Rendering Tips for Patch and Repair Work

Ernie Cook, the master bricklayer, who I had the pleasure of working for in my teens used to say “The worst thing that has happened to the building industry is cement”. It was a bit of an exaggeration but we spent a lot of time travelling around London and the South East putting right the work of bricklayers who were born into the cement age and knew nothing of working on buildings built with sand and lime.

The results were cracks appearing where they had never been before and spalling brick faces caused by moisture trying to find an escape route. All this because the brickie had the wrong mix for the job.

“If only they would use a bit of lime” said Ernie.

“If only they would use a bit of lime we would be out of work” I replied.

Lime is a magical material that has the ability to move and reconstitute itself in mortar, render and plaster. It is said that during the Blitz many of the buildings built with lime would jump minutely to absorb the impact of a nearby explosion whereas the sand and cement buildings would crack apart and stay cracked.

It is a golden rule of bricklaying that the mortar should be no stronger than the material it is joining together. That, in a nutshell, is the reason that Ernie Cook had such a poor regard for cement mortar. It wasn’t the fault of the cement so much as the lack of knowledge of those using it.

Nowhere is this more evident than in modern building with lightweight aircrete blocks. The mortar used to build block walls should be around 1 part cement to 8 parts of soft sand but it is rare to see bricklayers changing the mix (gauge) between the blocks and brickwork which is typically laid 1 part cement and 4 or 5 parts sand.

Limey mix for rendering

The result is that the blockwork moves at the weakest point which is the block itself and not the mortar. This produces cracks at the place where the blocks are most free to move, which is usually directly under windows. The cure, according to some builders, is to use an even stronger sand and cement render mix as a base coat for plaster. I have seen this done on so many occasions that I have lost count. Of course now the use of dot and dab plasterboard hides the cracks from view.

Another common problem is a strong mix of sand and cement render on exterior walls. Some plasterers think this stops cracking but sand and cement will always shrink and it pulls the brick or block with it producing hairline cracks. Until you’ve seen it you won’t believe how much water can run down a wall and track in along horizontal hairline cracks.

The capillary action sucks it in to soak internal faces. I have seen walls covered with the white web of dry rot simply because water has tracked in through cracks that you would hardly notice with the naked eye. Even worse is when well-meaning builders rake those cracks out and fill them with even stronger sand and cement or resin thinking that it will stick the building together. What then happens is the seasonal movement in the building causes the cracks to push upon the hard repair and lever the cracks open even more.

So faced with all this grief, why are brickies and plasterers still so anti-lime and pro-cement?

The reason that many won’t kick the habit or at least cut down is because putting in less cement makes the mix difficult to work with. It loses moisture into the bricks and won’t stay on the trowel. The simple answer is to use an equal part of hydrated lime and cement but this means ordering two different materials and mixing them together.

The modern answer is to use plasticiser which mimics lime by putting lots of tiny balls of air into the mix to help it flow. While plasticiser introduces air to increase workability and help frost resistance it doesn’t have the same stickability as lime. It does, however, allow the brickie to use less water which helps reduce shrinkage so it is a good second best.

The same effects can now be achieved by using enhanced cement which has plasticisers in a powder form but, in my experience, it still isn’t the same as putting hydrated lime in. The ratio of hydrated lime to cement is important. The lime should not exceed the cement. If you use more lime than mortar it is likely to fail if the frost gets to it. A typical mix is 1cement 1 lime 6 soft sand for bricklaying or sharp sand for rendering. If you want an even weaker mix for internal blockwork then a 1.1.9 can be used.

Not only does the hydrated lime help the workability and adhesion of the mortar it also retains the moisture during the initial set to assist hydration. The set takes place before the mortar has fully shrunk which means it is less likely to crack.

Even if it does crack, say with building movement, the lime helps the mortar to self-repair by leaching lime into cracks. The lime then reacts with the atmosphere to form limestone in much the same way that stalactites are formed. This makes it the ideal material for repointing brickwork.

The most important thing you have to get to grips with is that hydrated lime is different to hydraulic lime.

Many people confuse hydraulic and hydrated lime. The use of hydraulic lime in bricklaying, rendering and re-pointing is old school but is now largely confined to historic buildings. Hydraulic lime sets in days, sometimes weeks and is much too slow for most builders looking for fast track solutions.

Hydrated lime mixed with cement is far quicker to set. It is the reaction between the hydrated lime and the cement which makes it set, if you leave out the cement it simply won’t set. Although hydrated isn’t a direct substitute for hydraulic lime, it does give some of the benefits.

If you are extending an old building for example and want a good colour match but don’t want to go to the trouble of using hydraulic lime then hydrated lime is the next best thing.

If all this has started your head spinning just retain one thing. Next time you are doing a bit of above ground bricklaying or rendering buy a bag of hydrated lime from the merchants and add it to the mix in equal quantities to the cement. The instructions should be on the back of the bag. If you do this you will never go back to straight sand and cement.

Why did the shower tray crack? Roger’s tale of woe

Ladder Safety – Save your life

Roger talks about ladder safety after a recent tragedy on a site he was working at

In this episode we see Roger using the Youngman Fibreglass Stepladder, and the versatile Hunter Ladder from Ladder Safety Devices. We also see his neat ladder seat which sadly isn’t available anymore, so you’ll have to borrow Roger’s.

“A few weeks ago I was working on a site where somebody died by falling off a ladder. I had gone to collect some thermal boards and he told me he would give me a hand to unload. When I got back he was in intensive care and shortly after that he was dead, victim of a brain haemorrhage. The fall was from just over 2 metres. The ladder was set against a plastic gutter on a single story building.

“Nobody should ever put a ladder against a plastic gutter but on a low rise building many do it because the perceived risk is low. I could easily get side tracked here talking about the nature of risk, but the bottom line is that we are often in the most danger when we think we are safe.

If there is a risk of falling don’t just leave it to chance, do something to mitigate the risk. It is a common misconception that you are not allowed to work from ladders. It is certainly true that you should only do limited short duration jobs from a ladder and you should have three points of contact with the ladder, so that probably means one handed jobs. It follows that there is not much point hanging onto a ladder if it is able to move.

“Stopping a ladder moving can be done in many different ways. You can get a bloke on minimum wage to stand on the bottom rung. Personally, I have never had much faith in ladder footers, they tend to get bored and start texting or looking at passing members of the opposite sex, or perhaps the same sex. I can well remember having a casual labourer who was given to smoking a joint while making phone calls, when he should have been looking after the bottom of my ladder. If the choice is between him and a bag of sand, give me a bag of sand any day. Better still give me a ladder stabiliser.”

Videos from the web: Builder demolishes work after client says they can’t pay

Builder demolishes work: Builder Nigel Gray got so fed up waiting to be paid £15,000 for a construction job at a council owned property in Shoreham he decided to destroy his own handiwork.

The tennant, Anita Dovey, who had been given permission by the council to make the changes to the property, was given several chances to pay the bill but when she failed to do so the builder began demolishing his work in an attempt to salvage some of the materials used and recouperate some of his losses.

Mr Gray used a sledgehammer to break up the porch from Anita Dovey’s home, removed the conservatory one window at a time and took away the French doors.

https://goo.gl/n35XvD

Mr Gray told the BBC: “I’m absolutely gutted to have had to do this because it was such fantastic handiwork but I could not just let this go.”

“We just kept on getting a string of excuses and bounced cheques.”

When the work was not paid for, Mr Gray said the local council gave him consent to demolish his  work.

A council spokesman said: “Council tenants are allowed to make improvements to their home. Unfortunately, this private agreement has gone wrong.

Supercove How to: Trade tips on cutting and coving

Roger shows you just how easy it is to cut and fit coving using Supercove

SuperCove lightweight coving is available from many good builders merchants and DIY stores throughout the UK and Ireland, in various length options up to 4 metres.

With super-light SuperCove, you can fix coving quickly and easily – adding value to your home with the minimum of effort.

SuperCove is faced with a high quality paper-board – ideal for painting, with no need to prime. The polyurethane core, unlike polystyrene, will not melt or drip if exposed to heat or flame.

Despite the fact that there are a lot of different styles of coving out there,  the plain concave coving that has been the standard product for many modern homes over the last 40 years is still in  big demand. The big difference now is that there is a high quality alternative to the heavy gypsum based product that we all used to fit a few years ago. Supercove has a  polyurethane core that makes it exceptionally rigid and a white card/paper face that gives it crisp edges  with a finish that often needs no further decorating.

The lightweight coving means that you can stick it up with a minimal amount of adhesive and it genuinely does not need propping or pinning. There are still many die-hard plasterers out there who would rather use a gypsum coving because they can run the corners in with a bit of board filler and close up any mitres which are a bit gappy. I would not dream of taking away their fun but for me the cutting of accurate mitres is easy enough to achieve with the guides.

When it comes to cutting you have a choice of using the blue plastic Supercove mitre guide, your own mitre guide or a mitre box. The manufacturers recommend a sharp craft knife which produces a sharp line that doesn’t need sanding. I tried this but without a longer blade it is difficult to set the knife against the former. If you have a sharp blade that it long enough by all means try this.

The mitre box works well provided you remember to set it at the same angle that the coving will be fitted. That is to say that the top and bottom must be equidistant from the corner.  For me the easiest way to cut Supercove is with a fine tooth saw because it allows you to set the blade against the guide to produce the correct angle.

If you are new to coving here are a few tips.
1. It pays to mark the top or bottom of the cove so you know which way you are cutting. If you keep the bottom towards you on the bench you will find it easier to orientate and make the correct cut at the corners.  Internal corners have the long end at the bottom and external corners (around chimney breasts) have the long end of the cut at the top.  The guide allows you to do this easily.

2. You can buy Supercove in 3metre lengths but it is likely that you will need to join two lengths together.  Some people do this with a straight 90 degree cut but it is a lot better to cut a 45 degree cut with your mitre guide and joint the two bits together.  You can then run a damp sponge lightly across the adhesive/filler.

3 Always mark the wall and ceiling with a pencil so you get the coving evenly set between the wall and ceiling. If the corners of the room or chimney breast are not quite 90 degrees it is best not to try cutting the mitres to suit. Stick to the 45 degrees and gently roll the corners in so the mitre closes up.

4. If you are fitting around a bay with 45 degree angles you need to cut 22 ½ degree mitres.

How to: Fit an electric shower (Bristan Joy)

0

This is an instantaneous thermostatic electric shower that’s designed to be easy to fit. It’s a modern-looking case, and it’s designed to cover over existing footprints of showers, so if you’re replacing an electric shower, then hopefully this will cover over all the screw holes; you won’t get involved in any retiling.

But here’s the other thing; they make it easy to fit with a choice of pipe entries. You can come in either on the left or the right hand side, and you’ve got a channel coming down, so if you’re coming in from the ceiling with an exposed chrome pipe, you can run down inside the channel, swivel the elbow around, and then pop it straight in. Or you can just swap it over and come in the other side. They make it as versatile as possible.

It’s a well-known fact that not many people ever read the instruction booklet, which is a bit of a shame, because it’s only when the job finishes and something goes wrong that people reach for the instructions. The instructions for the Bristan Joy are easy to follow. They’re clear; you don’t need to be a scientist or an engineer to follow them. And they also have, in the middle, a very handy fixing template, which is useful if you’re setting out for new work. But if you’re going on to existing work, you probably won’t need the template. You’ve more or less got to put the shower up over where the pipe and the cable connection come in and make sure that you can work with those. But it is a versatile shower, so you shouldn’t have too much trouble.

Okay, we’ve got the template leveled up nicely now, so we’re ready to mark these fixing holes so they’re ready for drilling. Now, some people get very worried about drilling tiles because you can do a lot of damage. Some people say stick a bit of tape on there, stops the drill from skidding. But here’s something that I do. It’s a tip that’s going to raise alarm bells with some of you, I know that. But what I do, is I get a screw or a nail or anything like that, and I just mark the hole with a very tiny little tap. What that does is it just breaks the glaze very, very slightly, so that when you drill, the drill wants to center on that point.

Also, if I’m fixing something like a shower, I only put the top two holes in. I don’t mark and drill the bottom hole until I’m absolutely sure that the thing’s level. That way, if you need a very slight bit of adjustment, you’ve got it.

In this situation, we’re using a rear pipe entry, and that will be typical of a lot of replacements that you’re doing. We need to trim this pipe to make sure that it goes into the elbow. The elbow protrudes very slightly past the back of the unit, which to my mind is not ideal, but so long as you make sure that the hole around the pipe is big enough to accommodate that bit of elbow, you’ll be fine. I’ve got to trim it. I’ve worked out that it’s 16 millimeters of pipe protrusion beyond the tiles to get into the fitting, so I’m going to cut that with my pipe slice.

At this point, what I would like to do is hang it on the wall and offer it up on the pipe work, just to make sure that everything’s right. But there is a problem here: in Bristan’s instructions, they say that if you’re going to use a rear entry pipe work, you need to have access from behind. They say that for one very good reason, and that’s because once the push-fit fittings are in, they’re locked taut, there’s no way that you can remove them again from the wall, because if the pipe work is fixed and you can’t pull it out, then you’re stuck.

What I do – it’s a little tip – with these collets here, you can just, if you’re careful, flip them out with your fingers, and then you can try a trial fit without the pipe locking on the fitting. You must remember to put that collet back in finally; otherwise there’s nothing to stop the fitting from pulling off the end of the pipe. But just temporarily, while you’re doing the trial fit, you can take that collet out, put it in a safe place, and pop it back in afterwards. That’s perfectly acceptable.

Before I leave this subject of pipe positions, there’s one more option which is included in the Bristan instructions. Rather than coming through the back and having that problem that I talked about with the collet locking on, if you’re worried about that and you’d rather be able to get the shower on and off the wall easily, what you can do is put an elbow in the existing pipe. There may already be one on it. It doesn’t matter whether it’s compression or capillary elbow. But if you just then turn the pipe down through 90 degrees, you’ll find that you can just pop the shower on that way. That way, it’s very easy to remove it if you ever need to.

Okay, now we’ve got the pipes in and it’s time to look at the wiring. If you’re doing an existing shower, then the cable is probably in there, and you’ll just want to adapt that to the shower. You can come in from either side, or you can drop it down on the surface, so there are a few options there.

If you want to come in from the right hand side, you can either come in through the back of the wall or you can come up through the entry point and then put the conduit on. If you pop the live and the neutral behind the filter housing, and then the earth, you can just bring around the front there – there’s plenty of room that way. Not too crowded. And then you can make your connections up through the channel.

When it comes to connecting to the terminal block, there’s a sign here, a little label, which says that you’re going to make sure that all these terminal connections are tight. The reason for that is that these things draw quite a lot of power, and if you’ve got slightly loose connection, you’re getting an overheat and you can get a burnout of a cable. I’ve been to many showers which have stopped working and found that it’s just been loose terminals which have caused the cable to burn out. That’s an important point to remember.

Now it’s time to fit the riser rail. The riser rail’s only got one hole in it, because there’s only one fixed position for the screw. This is useful because if you’re replacing an existing riser rail, then you can adjust the screw holes on this riser rail to fit the old one.

Okay, so that’s it. Our basic installation is done. I’m just waiting for the electrician to wire up to the RCD and put his isolating pull cord switch in, and also I’ve got to put an isolating valve on the cold water supply. Other than that, it’s ready to go, but obviously I want to put the shower screen up first.

But before I do that, I just want to explain a little bit about the controls. Scale is a problem in hard water areas. Electric showers are prone to it because they heat the water to quite a temperature in a small cylinder. It’s a bit like the kettle, if you like. So Bristan have thought about this. They’ve done a lot of work on it. One thing they’ve done, in the electronic controls, there’s a run-on. So when the shower’s turned off, it runs on to clear the water out of the cylinder so that it’s not hanging around forming scale. That helps enormously.

Also, they’ve got a quite clean head. This has got a three position on it, which helps to just move it around every so often. But you can wipe the surface clean, and that gets rid of some of the scale. And there’s also a filter which can be taken out and cleaned every so often, and just run through with cold water, just to make sure that’s nice and clear.

So those three things are going to extend the life of the shower and hopefully solve a few of those scale problems. It comes with a two-year guarantee, so that shows that they’re confident about it. But if the customer takes care of those small points, it will increase the life of the shower.

Impact Driver Vs Drill

Busman’s Holiday – A Plumber in Cyprus

0

I have just returned from a one week holiday in Cyprus. It was a cheap break and we weren’t expecting fantastic weather at that time of year but we stayed in a 5-star hotel with plenty of facilities and a good sea view.

We would both have been quite happy to sit and read a few books but as it turned out the weather was really good and we were out walking and cycling along the coast and up into the hills.

That left us thinking that we weren’t really taking full advantage of the two swimming pools, spa sauna, steam room and gym at the hotel.

So on the third day, we decided to remain at the hotel and have a lazy day on the sun loungers. It was all going well until the chop saw and impact drivers started.

Over in one area of the vast grounds the guys had started laying new hardwood decking. I ignored it as long as I could but in the end I had to go and have a nose. 

I then discovered they were also tiling a new pool for children.

Then by the end of the day, they started laying large steel trays ready to mesh and concrete.

I told my wife that they would soon be pouring concrete into that tray and vibrating it into place. 

I wasn’t entirely sure how they would get the ready mix lorry in.  It turned out they didn’t. It was done by five guys with five barrows.

It wasn’t so much that all this activity disturbed us rather that I felt decidedly lazy lying there while others were working. That urge to get up and lend a hand was too much.

We decided to move to the indoor pool area. It was then that we saw the notice. As from the following morning, the indoor pool was going to be closed for maintenance.

When they said ‘maintenance’  they meant it.  In one day the pool was drained and scaffolded out. The next day they took the glazed roof off and attacked the perimeter with 10 kg jackhammers.

Thoughtfully the hammers were shrouded in sound -deadening jackets.

In a strange sort of way I felt quite at home there on the lounger reading my book surrounded by this cacophony and  It didn’t seem to be bothering my wife that much either.

That is possibly the only compensation of having spent the last 30 years living in houses that are constantly being knocked about or ‘improved’ as I like to call it.

That said it felt like masochism, so the next day we put on our walking boots and headed for the hills.

Product review: Hilti TE 1000-AVR Breaker

Power and safety are the cornerstones of next generation Hilti TE 1000-AVR breaker.

Hilti has launched its next generation TE 1000-AVR breaker, which has more demolition power and less vibration than its predecessor.

Utilising the company’s new HiDrive technology, which features a brushless motor, dynamic transmission and electronic power steering, enables the tool to create 26 joules of high impact energy and a hammering frequency of 1,950 impacts per minute.

The Active Vibration Reduction (AVR) system cuts tri-axial vibration from 6.5 m/s² to 5 m/s², meaning the product can be used for eight hours per day before reaching exposure limit value (ELV).

Hilti TE 1000-AVR Breaker 2

In addition the tool, when used with the TE DRS-B dust removal system and a Hilti M-class vacuum, removes up to 97% of hazardous fine dust from the point of impact for a safer, cleaner environment. The system also protects the machine’s workings, meaning continuous performance and reduced downtime.

Productivity can be improved still further with Hilti’s recently launched TE-SP chisel, with features an innovative ‘wave’ design for more breaking power and less sticking, which in turn markedly increases performance.

Applications include demolishing concrete and masonry at floor level or below waist level, corrective chiseling, removing tiles, bushing and compacting and renovating floors.

Tom Clegg, Northern Europe Product Manager (Heavy Duty Tools) at Hilti, said: “To increase power is one thing but to significantly reduce vibration numbers with optimised levels of dust extraction – without compromising the weight of the machine – makes this tool a truly innovative development.

“Alongside the recently launched TE 80-ATC AVR combihammer, plus the larger TE 1500-AVR and TE 3000-AVR heavy-duty breakers, we have a cutting-edge portfolio which will maximise productivity across the board.”

The TE 1000-AVR can be purchased through Hilti’s Fleet Management programme whereby a fixed monthly charge covers all tool, service and repair costs over four years. For customers who prefer to own their own tools outright Hilti’s Lifetime Service gives a complete no-cost period of two years.

The renewable heat incentive that’s anything but

Underwhelmed By The Renewable Heat Incentive

Regular readers of this blog will know that I am slightly underwhelmed by the government’s Green Deal and also by the way the RHI (renewable heat incentive) favours those companies that are willing to go through all the red tape it requires to become an approved contractor. For the smaller builder (like me) these schemes offer little or nothing.

I am currently working on a house that doesn’t have mains gas. The householder is keen to install as many renewables as possible and I quickly realised that I would not be able to help him. I got the job of ripping up all the floors and installing underfloor heating throughout, but when it came to the solar thermal I was unable to sign off the job so he could qualify for the RHI. We looked at using an outside contractor but they were double, sometimes treble, my price. Good luck to them but it means that any saving through the Renewable heat incentive is being mopped up by the installation companies, not passed on to the consumer.

I wouldn’t go so far as to say it’s a cartel but when you look up how many companies operate in this field it is an exclusive little club. Even getting them to quote for the job is impossible, they are interested in new build housing estates not one off jobs for private clients. It’s been the same story with heat pumps. I contacted over ten companies and not one of them came back to me. My customer was getting impatient. He embraced the whole concept of green energy but he wanted to get a move on. His house was cold and his wife was unhappy.

We had a meeting, and worked out the total value of the government incentives and set them against the savings he would make using a one man band like myself. Of course we didn’t have any actual quotes to go on but we found some examples of jobs on the internet. The other advantage in not going for the Renewable heat incentive is that he won’t have to pay someone £300 for an energy assessment. The house already has cavity wall insulation; 200mm loft insulation and triple glazing. Short of relocating it to the Caribbean there isn’t a lot more they can do to cut their energy consumption. I wonder if there is a government grant available for that.

Cordless jigsaw Product review: DeWalt DCS331M2

This cordless jigsaw has loads of capacity and grunt to complete the average kitchen…

There are two kinds of product tests that I carry out for Skill Builder, explains Roger Bisby. The first is to take a brand new tool out of the box, and give my immediate impressions by taking it out on site, hopefully letting a few of my fellow workers give it a go to get their opinions. This has obvious limitations because some problems take a while to surface.

The second kind of product test is to use to use a tool for several months and then report back. This is the test I prefer, but most manufacturers are understandably keen to get their new products out into the market place, and some are also very keen to get them back. Often they are on the phone asking for them back before I have had a chance to run them around the block. What are they afraid of? Do they think their shiny power tool will fall apart?

Refreshingly, some give you a little longer to get acquainted. I first took delivery of this cordless jigsaw over six months ago, so it has had some good use! A few years ago I would have said a cordless jig saw is a tool to get you out of trouble, rather than as a replacement for a corded one, but battery technology is now so advanced that you could use this as your only jig saw. I don’t think you would find a job that it would not do as well as the corded version.

Coupled with the 18 Volt 4amp hour battery, this cordless jigsaw has loads of capacity and grunt to complete the average kitchen…

Having said that, you will notice that a cordless jigsaw is considerably more expensive that a corded version. So if you work in easy reach of a power supply there may be no reason to go unplugged.

If you are already a committed DeWalt cordless jigsaw user running on an 18 Volt XR platform, then you can buy the naked body for the same kind of money as a mains power model.

What you want from a cordless jigsaw, is enough runtime to cut through worktop and the like, without running out of power part way through. Coupled with the 18 Volt 4amp hour battery, this cordless jigsaw has loads of capacity and grunt to complete the average kitchen fit and still have something left in the bank. If you are cutting laminate worktop, you are more likely to stop for a blade change than a battery charge. I just couldn’t believe how many metres it had in it. One day perhaps over the Christmas break, I will do a proper measurement of how many linear metres it will cut on a single 4AmHr battery.

When you do need to change the blade, the large lever on the front is easy to flick out, even with gloves on, and the T pattern blades lock in easily and stay put. Similarly, there is a lever at the back to adjust the base plate angle for bevel cuts.

The other features of pendulum action, variable speed and fan blower to clear the cutting line, are standard on all good jig saws. If you use this saw, you may wonder why it feels a cut above many of the others out there. The difference is the counterweight on the action, which dampens vibration and gives the saw a lovely controlled balanced feel, even on the full pendulum setting. Until you have used it, you don’t know what you are missing.

In fact the other day I saw a PVCu cladding guy making a dog’s breakfast of a bit of fascia. I could see it was almost entirely due to the grabbing action of the piece of tat he was using. I thought about how much better he would do the job with a decent variable speed machine, that gave a nice soft start. I thought about it, but I didn’t say a word. If it was you, then I am sorry, but you know now. There is a better tool out there, and it will make you a craftsman rather than a butcher.
