Hi all.
I wonder if anyone can give me a little bit of information about blue grit, as I’ve never used it.
I have a garden wall which I painted end of last summer, some strange mix was used on the wall, I’m not sure what they did but loose had come off and the top coat of render was thin and black (maybe unibond or sbr in the mix). Anyhow, I patched in where necessary and when dry painted the whole wall.
Once the weather became wet and cold, I noticed the paint blistering on the most exposed part of the wall (not bits that I’d patched), it looked like small pox there were so many blisters. Since then it got worse and has come off almost in sheets and I’m going to have to do it again when the weather breaks.
I’ve done plenty of painting over the years but have never seen masonry paint behave like this, it simply did not adhere to the surface. I did all the prepping and jet washed it down etc. before starting so am flummoxed as to the cause. Masonry painting has never caused an issue for me before.
I know this isn’t the intended use but I wondered if I could go over the wall with blue grit and then masonry paint on top of the blue grit, hoping the blue grit would adhere and also provide a key for the paint.
I’ve never seen blue grit, would it leave an awful looking texture? There’s a poor texture on the wall anyway but it’s looks good enough with a coat of paint on it, would blue grit look bad painted over or is there some other reason why this won’t work, such as you wouldn’t be able to paint directly on blue grit?
I’m just thinking out of the box at trying something different so I can’t paint it once and be done with it and thought blue grit might give me the adhesion that I need.
Anyway, it might sound mad, I don’t know but I’d welcome any advice anyone could offer about this, whether it’s possible or plain ridiculous. If this isn’t likely to work out then I might clad it as I just want it at a finished standard but if I can pull it off with a couple of coats of paint then I’d prefer to do that as it’s a very long wall and will come at a price.
Thanks in advance
Ern.
