Question 2

I applied this product 10 years ago on my interior, colored concrete floor. I think it has performed well, though certain stains have still gotten through- cat puke in particular- I guess that's pretty much acid...Question: can I re-apply another coat? Will it penetrate or just sit on the surface? How should I deep clean stained areas first? View answer

Hi! We exposed concrete columns in our 1961 condo and think it would be good to apply a sealer of some sort. One reason would be to create a smoother service in the event someone brushes up against the wall so clothes won't snag or skin won't get scratched. What product would work best for that? We are not looking to paint and do not want a wet look Thank you! View answer

Question 38

I applied the micro etch to concrete that had been power troweled. Afterward I found a tiny pit in the concrete (1/32�). Will these pits be sealed up and flush with the top surface of the concrete or will there always be a tiny pit? What would you recommend I do, before or after the sealer, to address any tiny pits? The concrete was previously smooth as glass and I could not perceive any pits before hand at least, but they may have been there. Should I not leave the micro etch on as long as I did? (5 minutes then scrub with a brush as the bottle suggested). View answer
