Question 3

We built a new granny unit and want to paint the concrete floors. Masterlife 300-C was used in the admixture. It forms a crystalline structure within the concrete preventing water penetration. Would your Safecoat Concrete Floor Paint adhere to this surface and if not could you suggest or recommend some other treatment? View answer

Question 5

I think I need to seal my very old (from 1955) concrete basement floor but it has small holes (from nails that were taken out along with small amounts of concrete) that need patching. What should use to patch it with that will still allow the GBS penetrating sealer to be applied? I assume I can't patch it after applying the sealer because of adhesion issues. I intend to paint over the sealer. View answer

Question 6

Does AFM SafeCoat, Concrete Floor Paint block formaldehyde emissions? At first I was looking at AFM Safecoat Safeseal to put on part of the concrete floor to seal in formaldehyde, but that's only for plywood type surfaces apparently. But I liked that one because it blocked/sealed formaldehyde 100% and was very low VOC (around 22). View answer

Question 36

Hello! This looks like a great product for our garage floor. What would you recommend for the garage walls (and basement walls)? They have not been painted in decades, have been known to get damp (even wet after heavy rainfall). Would you recommend sanding first (with what product), then priming (with anything in particular), and then painting? We'd like a product that is eco-friendly/non-toxic/low-VOC but that will also hopefully protect against moisture/mildew etc. Thanks very much! View answer

Question 38

I am restoring the interior of a building which has a poured concrete floor and block walls. Previously, both the walls and the floor were painted, but since at one end of the building the ground rises several feet up the wall on the outside, the moisture from the earth managed to seep through just a little, causing damp on the floor and wall in that area, and eroding the paint. What product would you recommend to solve this slight dampness? would its use require me to remove the old paint completely (which would be a chore)? I intend to panel the walls and repaint the floor, and do not want recurrence of the problem. View answer

Hi! i bought a gallon and painted the inside of my planters but read in your instructions it should not be exposed to sun or the elements. Since mt boxes are angled, above soil line there will be 10 inches exposed to sun and rain on all my 10 planters. Should I coat this with something else? Ideally white (and even more ideal if i don't need to coat again but i do want it to last). Thank you! View answer
