Concrete & Masonry Sealers Q&A

Question 1

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
