Please see pics https://flic.kr/p/2hUQkJS https://flic.kr/p/2hULGKo https://flic.kr/p/2hUPaRX I've done 2 coats of this paint and 4 months later it looks a mess with bubbles everywhere. BBQ is built with blocks and been sand and cemented skimmed After scraping and sanding it back, what painting method should I follow? Thanks
Couple of coats of stablising solution first to ensure the paint adheres properly, but looks like there could be moisture getting in the blocks somehow.
masonary paint will stick to most surfaces.the only probs is if no prep is done.make sure its clean no oil or dirt etc first also the surface must be completely dry
Could simply be due to the paint no adhering properly, stablising solution (properly applied) should sort that.
What are the blocks sitting on and guess lightweight block construction ? Porcelain patio looks fantastic, as does the overall design but those bbq blocks are soaking up water/rainfall from somewhere May only be a simple block built bbq area but still needs planning before 1st block is laid to prevent water soaking up from base blocks, rising up through blocks then blowing paint off as it escapes outwards Think engineering bricks for base and DPM, then blocks Seems overkill but now you’ve got a damp problem I’m only diy, see what others think
+1 A DPC is essential in any wall in the garden,whether freestanding,bbq,bar,etc,to stop moisture being soaked up in wall, but seldom done.
Hi all, it's just built on the actual patio flags... I didn't realise moisture would travel upwards. Anything I can do to at least minimise it? I should of had it built on bricks or a DP, but not much I can do now. Plastic trim around the bottom like a skirting board? Some magic paint? I know I've messes up or the guy I paid to do it, but must be something Please help
Patio looks great (from my phone anyway) So did a pro do the patio, bbq, etc ? Rain is landing on the tile planks, hopefully there’s a slope away from house to drain water but water is clearly soaking into base layer of blocks plus, what’s it built on ? Guess it’s not sitting on tiles but what ? Concrete strip foundation / hardcore / soil / etc /? Anyway, that’s the limit of my knowledge pointing out the likely cause of damp I wonder (and I really don’t know) if you could drill holes around base and inject in a chemical damp course layer ? I really know nothing about these apart from system is often used around houses when the original DPC has broken down Equal amount of bad press about these injected DPC, lots of them on this forum Take advice and read up, it’s something probably worth trying, you can do it yourself and for this small area, surely not gonna cost much Now over to others / pros / etc Good luck
Yes someone local did it. To be clear its not built on sand or anything and has zero DP apart from being built on the patio flags. I might do 4 coats of a really thick interior gloss paint and 3x sandtex exterior and build a plastic skirting trim at the bottom Open to suggestions
I would think that ‘4 coats of really thick gloss paint’ would be the worse thing to do as this will totally stop the wall from breathing and prevent damp from drying out So saying, the gloss will only stick to whatever paint is on render now so, if bass paint bubbles, then it will simply lift gloss off with it Tricky one Injected chemical damp course anyone ? May seem over kill for a bbq but this needs sorting

Thanks.. They say to drill them along the mortar line, I won't be able to find the exact motar lines as it's rendered, does that matter?
