Concrete & Masonry Sealers Q&A

Question 1

Will GBS Penetrating Concrete Sealer work for polished concrete? Do you carry any caulk, sand, or silica substance that can be used to fill cracks in the concrete prior to applying GBS Penetrating Concrete Sealer?The concrete in the basement was recently ground to "salt and pepper" look and caulking from radon mitigation was removed with it. The radon levels went up from what they were before. There are various hairline cracks that I planned to grind clean and fill prior to applying the sealer. View answer

My landlord just re grouted the grout lines on our kitchen countertop which has porcelain tiles. Our place is very old, and he used a white TEC Color Matched Sanded Caulk Grout. It has cured but is a little rough because of the sand in it. He said he is not doing anything else to it, but will pay for inexpensive material(s) for us to do our self if there is something to smooth/seal it. Would grout sealer work? We have kids and really need to get this fixed. View answer

Question 38

Can you use a sprayer to apply? I have a 100 year old house with a fieldstone foundation. When I purchased in 2006 it was already coated in a thick white covering that was peeling off and as a result there is lots of dust from the crumbling stone. I tried to cover it with a product I got from Home Depot that had to be brushed on. I had to use a large bristle brush and it was next to impossible as the stuff was so gloppy that as I brushed it on it would pull off what was already applied and it was difficult to get into the crevices. I also rolled it on to my damp concrete floor. It all started peeling off within a year. I need something that will seal my floors and foundation from the inside that can be sprayed on. View answer
