Customer Questions & Answers

Is this made for non sanded or sanded grout?

Asked by: lynniebee
This sealer will work on either. I just re-grouted my bathroom using both sanded and non-sanded grout. On both, I used this stainblocker without any issues whatsoever...Just follow the directions on the bottle and you won't have any issues either.

how long does stainblocker for grout by custom building products last as far a sealer

Asked by: Anonymous
It has a 1 year manufacturer warranty, but I haven't found any actual homeowner info on how long one can expect it to last beyond the warranty period. Undoubtedly, it will depend on whether or not it's used in a stain-prone area (like a tile countertop or floor). I haven't had mine long enough to say for sure, but I can say that it's well worth the minimal extra cost to add this stain blocker to the grout mixture during the initial application.

Stain Blocker Update

You state in your reply that the Stain Blocker is a sealer designed to repeal dirt and make cleaning easier and will not make the grout waterproof or stain proof. Well my question is, why is it called stain blocker and depicted on your container label water beading in the grout lines.
Asked by: Dayton
Unfortunately, the answer given to you is not completely accurate. This product is a stainblocker/sealer. It does make cleanup easer by preventing dirt, etc. from working it's way into the grout. This product also does prevent stains in the same way I just mentioned. As far as water beading up on the tile, this product won't do that completely. It will provide some degree of water repelling qualities, but only on the grout which is where this product is mixed into. The degree of stain and water resistance is in direct relation to the ratio you mix this with the grout. The included directions on the bottle further explain this.
