Sealing Grout for Tile
I wrote several months ago requesting information for sealing grout. I enclosed a stamped self-addressed envelope for a reply. To date you have not responded. Also, I have made four long distance calls to your office and your secretary asked me to write another letter, so I am following her suggestion.
I wanted information on a silicone product made by Aqua Mix (penetrating sealer). Would you please advise me if their product is harmful to grout and tile. I listen to you on KCBS and enjoy the program very much.
Aqua Mix makes a good product. It certainly can’t hurt, and may be the correct blend for your tile-grout problem.
You might also want to contact the folks at CeramaSeal Stone and Tile Care Products, P.O. Box 33322, Seattle, WA 98133. Their free technical assistance hot line is 1 (800) 356-4903.
Glaze ‘N Seal Acrylic Grout Sealer made by the Glessner Corporation in San Francisco is a product we have also used that works very well on grout.
A silicone sealer should not be applied to stop leaks in cracks. The grout should first be repaired. The surface should be very clean. A thorough scrubbing with vinegar, lemon juice or bleach should be do the trick. Surface grease (visible or not) will neutralize the effect of a silicone treatment.
