Sealing basement floor

If We are putting flooring down in our basement, is this something we could use to seal concrete first? We are putting tile down and wondered if we should seal the concrete first as extra protection.
Asked by: nhcurious
Heavy-Duty is recommended for vertical applications only. We do not have a sealer that we would recommend on a basement floor under tile.

Customer Reviews

5 gal. Heavy Duty Waterproofer is rated 3.5 out of 5 by 2.
Rated 5 out of 5 by from Great for sealing EIFS My customer had an ICF wall clad with EIFS that had water seeping through the EIFS and making its way into the cracks in the ICF blocks then around the window bucks and down to the floor inside the house. This water intrusion also came through the cold joint between floors and wet the sheetrock inside the house which was confirmed with an infrared camera and moisture meter. The outer wall was a parapet roof with no overhang, and there were visible cracks in the EIFS which were less than 1/8th inch. This heavy duty version of the Sealkrete product was recommended by the company's customer service rep instead of the usual regular product which is also recommended for EIFS. Since the product is acrylic base it is a good choice to use on EIFS finishes like Master Wall which also are acrylic base, and it is compatible with acrylic elastomeric paints which may be the ultimate finish coat. The rep suggested 2 coats. I applied one coat and it worked and thought that I would wait on adding another coat only if it leaked again or needed this product as a primer for some elastomeric paint. BTW, forget the sprayer. I had a much easier time rolling it on and was able to control the drips better that way. Regular 1/2 knap rolller I think is what I used. Before you stop reading you need to know one thing though. This product is similar to some paints, and you definitely don't want to be doing this when there will be dew or moisture on your surface before it has had a good chance to dry. I HIGHLY recommend you stop applying it well before night and make sure it has a chance to cure well. I found in the morning the product I put on on a November afternoon had some milky white areas with dew dripping down the wall and some of this product with it so there were some areas that look a little drippy where i had actually rolled over a second coat. Be cautious...very cautious and don't do it if any doubt. Also be mindful of low night temperatures making this problem worse. READ THE DIRECTIONS and be careful. With that warning out of the way I must say it solved the leak problem, and generally the wall looks great. So far it looks just fine after 1 year and no leaks. BTW, I used the standard product on another side of the house where there was less of a problem. It soaked in well and cured faster, but I don't know if it really sealed as well, and also it was much more messy. Both this and the standard product are pretty thin and drippy and not like thick paint that you can control so you need good protection below for drips. The great thing about this product is I ordered it online and it was delivered directly to the house at no extra cost. I would use this again. I saw some other houses that stucco repair pros tried to seal the leaks on the ICF walls covered with EIFS and it look terrible with all the patching work very obvious. This product gives a uniform finish but no color change...well not much. It maybe darkens it a tad, but you can't tell with normal light. Best of luck with your project.
