Treating Bleeding and Discoloration in Concrete Walls

garage walls do I need to Prime first or will masonry paint go straight on regards Garth in Ireland so their paints might be a little different than ours depending concrete walls um do I need to Prime um first or you know that's all going to depend on the product you're using so um you wouldn't need to Prime if you're using a masonry product like locks on XP I just recently did a video um painting block and I use locks on two coats of locks on rolled on with a interfeed roller so um you know if you're actually just using a paint you know it's probably a good idea to prime it but I use if I'm doing um a concrete wall I'm going to use like um you know you could if you're just trying to get color on and you don't care about filling stuff you know like um agency solid dollar stain you know would be great for concrete you know but if you're trying to fill and stuff you're going to want to use something like locks on which is a heavy body product that you know really fills too and you don't need to Prime you know if you're using that product you don't need a prime if you're using HC I'm definitely want it back well though you don't want to just spray it no matter what you're using you want to back roll it and the background enhances penetration and it enhances adhesion so I have a good question for you from Keith wind he said I did a white wash on my tongue and groove patio ceiling here in Florida so it's humid there I got mold on the surface can I put a a ceiling over it and what what kind yeah you're um you know I would have sealed it like a product that I've used in that type of application um Helmsman water-based um Spar you have um urethane is um is a great product um and it's water-based so it's but do you want like you have um primers like Rust-Oleum zinser has one that they wiped them all so you don't want to they're you don't want to cover it like um zinser's mold on killing primer that kills mold on putting over it is pure white yeah you would have to if you want to preserve your white wash you're gonna have to eliminate that mold by maybe a bleach solution spraying it on killing the mold then you're going to want to clear coat it so you don't have that problem anymore Helmsman Spar urethane they got water-based on oil based the the water-based doesn't yellow and simple easy to use I'd spray it back brush it is what I would do to get it on so Ian Mann says hi great content thank you for that my Q my question is I have stone around my window old paint…
