Grout sealants
Hi all. Newbie dumb question:

I'm trying to seal grout lines between glazed tile and the procedure is going well.

However, in testing I find water still soaks in after the recommended 2 coats.
The sealant I'm using is the Dupont water based found at Lowes.

The question: Is there a better sealant available that is truly a sealant and will not allow penetration? Also, if there difficult to use?

Thanks, much.

Post some pics of your grout lines, water is not suppose to soak in the grout sealed or none sealed and sealing grout doesn't make grout water proof grout is already meant to reject water once the grout drys.

Is this sanded or none sanded grout and is the sealer for which ever type you have?

Thanks, Jet!
First, you give me far too much credit. I've just moved in here and to find my camera would be amazing.

The penetration I'm seeing is almond grout (sealed) and darkening by pouring a small amount of water on it.

As far as sanded or unsanded: I have no clue. It's a resale home of approximately 10 years and it is what it is.

Thank you so much for trying to help. I'm sorry I don't have better info.

Any other ideas you might have would be so much appreciated!

Grout sealer is not meant to completely 'seal' moisture from wetting the grout. If sealer did that, it would peel off like oil-based paint on an old un-cared for house. Sealer slows the intrusion giving you a little time to wipe the spill. Apply a couple coats or so until no more soaks in. Be sure to wipe off excess from the tiles before it dries.

That makes sense! I guess I was looking for a way to avoid cleaning. :)
