    Pebbledash to smooth finish

    Quite right but I didn’t look at the photo close up, more on what I read. Yes on painted dash then parinter or Fassa K over. Subject to a pull test of course.

    Advice needed please

    Johnstones is fine, using it a lot alately. What is the repair? Whats wrong with it? Repair or repoint? Repoint is not needed and all the modern renders on refurb usually have reinforcing mesh embedded. K Rend monocouche has a bad reputation but their other renders are fine.

    Patching terylene.

    Getting it to match will not only need the same wetness but the wear on the tyroleaning machine, so down to a bit of experimentation. Minster insulation round here stocks Cullamix or try Johnstones one coat render thats a good alternative. also consider it is painted that has took the...

    Rendering on timber/ EML

    The chippies have done it the way it used to be done 15+ years ago. It can work with the right mix and practice which it sounds like your plasterer hasnt got but even then you will have a brittle render on a flexible substrate so cracking might be an issue. The felt will probably be the modern...

    Ghosting or something else

    There are some Council houses near me and when it rains heavy you can see the blocks showing through. No idea how thick but they was hand applied about 12 years ago. They was originally Webers white but now grey.

    Ghosting or something else

    Do you know what thickness the render is? You may find a horizontal Stop bead That will be either 10 or 15mm.

    Ghosting or something else

    There are several causes on one coat render. Different blocks, wet blocks, different suction in the substrate will give different setting times at the time of scratching back giving different texture giving different shades. Was it raining shortly after finishing? Could be salts coming out...

    or an extension on top of a garage? Fit brick stitch bars into it zig zag and double mesh with a thin coat system.

    Cracks on scratch coat?

    Yes leave it 6 weeks but do not use that clear stuff it’s water repellent but it doesn’t know the difference between wet water and wet paint, it will repel both.

    Cracks on scratch coat?

    You have left it to cure so it will be fine. Are you going to paint it? Jub make a siliconed paint that has some stretch in it or better still apply an acrylic or silicone render finish 1.5mm. Plenty of stretch there.

    Silicon thin coat render advise

    It’s all down to timing. Spray the first coat and if it stiffens up enough then spray the second. I scratch the first pass if it going to be left to set.

    Silicon thin coat render advise

    X32 is sticky on its own but you could use Eco rends liquid primer instead of rendaid. I have used their primer to stabilise a wall of different brick, block and concrete for even suction then x32.

    Cracks on scratch coat?

    Thats shrinkage cracks. Either too much suction or the heat. Tap it and if it isn’t hollowthen let it fully cure for at least 14 days preferably a month then carry on. I have seen worse. Strange why he would use mesh on brick. If it was smooth faced or painted then yes but a bit out of date...

    Cracks on scratch coat?

    under the metal meshing was it brick or block with suction or did he treat it with anything? Are the cracks small and more horizontal than vertical?

    Cracks on scratch coat?

    If it appears to be solid then crack on. The cold will be ok, safer than too hot and the damp air will help curing. even painting will be ok, just needs a few hours to dry so pick a couple of dry days..

    Rendering window reveals

    Bit unusual that ts, scaffolders price for erection and dismantle over a set or agreed time then in my case 5% of the price per week on hire. This covers the hire of Capital assets and a profit otherwise in time of boom the scaffolding company would have to hire in steel as their assets is tied up.

    The doser is good and it will give you peace of mind. My Ritmo and water pump needed expensive repairs after using Wickes and not flushing out.

    Pitched Face Render Circa 1900s

    I was taught how to do this in college but with raised pointing. a scratch coat was applied then the joints was marked out with chalk, then a thin band of render applied over the chalk lines and cut using a stick the width of the pointing and let set. Then mix up a sand, cement and lime mix and...

    Hot weather vs rendering

    The heat has killed it but it could have been avoided in a way. cover the wall up the night before to keep it in the cool, hot blocks just make the water in the mix evaporate. Avoid working in the sun but if you have to like you did then uncover as you go and re cover immediately. Not ideal...

    Masking up time, beading time, applying base coat time then mono which depending on who‘s could be a day, long day or an overnighter. Small areas or something worth going at? How much labour only are you? You and a bag of tools with someone supplying the equipment or a transit full of equipment...

    If its 3.5 newton blocks you might be ok but if 7 Newton then there is no need. I would prime with 3 water 1 sbr then when dry either 1:1 sbr and water but better still neat sbr and cement into a brushable slurry. For for ease then consider Everbuild Rendagrip. I prefer rendagrip, apply once...

    Rendering short term course

    You need hands on experienc, no short course can teach you that. How long did it take you to master skimming? No day is the same, for example skimming on a cold damp day in a new build is different if that same wall was in a heated house. Rendering is the same. Ruling off the modern renders...

    S+c on osb board

    I have done lots of bays over the years and no problems. Put breathable roofing felt on tight then expanded metal lathing or riblath as tight as you can. Perimeter beads as well. If you want bed some 8-10 mesh into your scratch coat or fibres for a belt and braces job. I doubt on boarding this...

    Pral M advice.

    I have done it in the past with good success. Put waterproofer in your coats but not in your final top coat so you have some suction and hopefully even suction. Scratch wavy and not too deep to avoid sag lines Top off with 10mm peak.m or more.

    Temps frost proofer

    I have used it once in mono but it wasn’t that good as an accelerator. Wickes worked well but I bought Larsens in bulk. Cheaper than Wickes without the chloride free additive.

    Temps frost proofer

    Putting obvious freezing weather aside its what if it turns parky overnight we should be considering. Well I have used Wickes and Feb Wintamix with good success. I have had two that did get caught and froze solid but are still there today. When I say solid is was white over with frost but under...

    Pebbledash to smooth finish

    depends how dirty, and also any organic growth so sometimes consider algicide and pressure wash but polluted mortar more likely than pebble.

    Pebbledash to smooth finish

    No not always but its me, I would be thinking of the inground dirt so something sticky for reassurance.

    Pebbledash to smooth finish

    If you are satisfied that your existing rendering is on sound and is clean then there are options. Talking in Weber product talk then a coat of their rend-aid2 then their OCR will give you a flat render. You could give it a coat of Parex (manufacturer) Microgobetis then their GPR. There are...

    Re-render one wall in krend

    The sides will be solid but the front will be little more than piers so subject to a weakness when the door shuts. If it is a porch then why not consider rendering the front with an o.c.r render (plain cement render) done with the right base and mesh and then skim over the sides with a thin...

    Full mesh coverage, or just stress areas? Johnstones silicon enhanced

    The op doesn’t state new build or refurbishment? New build with 7.5n blocks and one coat render then stress patches on opening corners will suffice or even good hard crack free bricks but usually it is common practice on refurb work to fully mesh.

    Hopper gun

    Unless he has seen that open hopper that does fire it on, Refina make a version of it. But you need one of those towable compressors the road diggers use to use it with. The compressor will cost more than a machine.
