Re: concrete sealers
I'm not an expert but have been told by many people that do concrete that for a sealer to last there needs to be a vapor barrier under the concrete. If not it will flake off over time. I used a cure and seal on my garage floors just after they were poured. I would use an etch on cured concrete before using any product on it. Again I'm not an expert but have built several garages.
