Hello
This is my first post here.
After 20 years of corporate grind, I managed to get out last year and have moved to Cheshire where I'm helping my girlfriend expand her property portfolio.
Having always been a keen and (reasonably) competent DIYer, I have been trying to improve my skills across a wide range of trades, mainly due to having been let down / ripped of by a couple of builders last year.
We are slowly going through the properties and renovating and a couple of the back yards need rendering to improve the outside space.
After quite a bit of research, we've decided to try some thin coat silicone rendering and I've ordered some from EWI to try it out.
The walls are a mix of bare brick / painted brick / bare block. So, I started by applying universal render to all surfaces to try and even out application suction. Next, I wanted to apply the EWI premium basecoat and mesh. We put all the beads on the wall and mixed up the first bag. Nice product to apply to the wall. Put on with plastering trowel, then used a notched trowel to get about 6 or 7mm (depth of beads) - applied the mesh onto the walls with 100mm overlap and then gently pushed in with trowel.
So far so good. All of the mesh was covered over but the mesh pattern was still visible in certain parts of the wall. Not sure if this is a problem or not. But the biggest challenges has been flattening the wall off after this first application. I've tried a combination of trowel and SF Speedskim. It seems as if you can only literally pass over the product once because after that, it seems to drag rather than smooth. This is ok for much of the wall but in a couple of areas there were low spots, which needed more product adding in. Was then just really struggling to get the wall smooth and flat without pulling the product.
Any idea what might be causing this. On the first wall, we ended up putting a thin (2mm) skim over the first pass about 24 later when it appeared to have dried. Then flattening with the speedskim, which has then just left a very thin overlap line, which I'm happy to polish out with a plastic float when drier.
But ideally, we'd like to be able to get the walls flat and smooth after the first pass, which appears to be inline with what EWI recommend.
The top coat is going to be 1.5mm silicone render and I know that I will need to apply the top coat primer and let that fully dry before putting the top coat on. I also realise that because it's such a thin layer, the base coat does need to be pretty imperfection freee.
Really appreciate any advice that anyone can offer.
Best wishes
Steve
