## Overview

The StoneTech Heavy Duty Grout Sealer is a powerful, water-based solution designed to protect grout from oil and water-based stains. Ideal for both indoor and outdoor use, it covers up to 1,000 linear feet per gallon and is specially formulated for cement-based grout with natural stone, ceramic, and porcelain tiles, ensuring your surfaces maintain their natural beauty.

## Description

Always test in a small inconspicuous area with a 24-hour cure time to determine ease of application and desired results. Allow new grout installations to cure for at least 72 hours prior to application. Be sure surface is clean, thoroughly dry and free of waxes and coatings. Surface temperature should be between 50F and 80F (10C and 26.7C) before sealing. Ensure work area is well-ventilated during application and until surface is dry. Keep children and pets out of the area until treated surface is dry. Expected wear is up to 5 years on interior surfaces and up to 3 years on exterior surfaces. Coverage is up to 1,000 linear ft per gallon, depending on porosity of surface.

Review: Used this in the past when it was DuPont. Do two coats, clean with Hydrogen peroxide and a little comet cleanser where really dirty. Rinse and recoat if necessary. Mine last ten years before recoating.
Review: Before trying this product I tried the one made by Mapei (same fabricator as the grout used) and despite the Mapei sealer bottle said will not change the appearance of the grout it definitely darkened it at the two areas i tested and the grout stayed dark after 72 hrs. So i decided to try this product to seal my grout. Despite being a lot more expensive than the Mapei sealer it DID NOT change the colour of my grout. I wouldnt have made so much as a fuss if the tiles weren't Italian porcelain 64" x 32" tiles but for the price i paid the tiles no way i was gonna cheapen on the sealer! I highly recommend this product. Easy to apply. Excellent procuct!

## Questions & Answers

**Q: will this seal sandstone**
A: My experience with the StoneTech products is they don't seal anything. Very expensive, tried different products and none worked.

**Q: About how many square feet of will this cover? I understand it depends on the tile size and the actual amount of grout.**
A: We have 20x20 tile on about 1200 sq. ft. in our new house.  Two applications on ours and two applications on our neighbor's (same size) with about 1/3 left.  So 6000 sq. ft. of tile coverage or more on this size of tile.  It will depend on tile size with smaller tiles having more grout but it works great and it's fairly easy to apply....I used a roller applicator.

**Q: Can this be used on a backsplash with white glass subway tile? Does it have an odor? If so how long does it smell?**
A: 1) Yes let it set for 5 minutes they wipe off....2) Hardly any noticeable smell...its water soluble so it really does not have any long lasting odor...

**Q: Can I put this in checked baggage on an airplane?**
A: No.  Have it shipped to wherever it needs to be applied.

*by D***N on 17 January 2024*

Did a lot of research about products & process. Settled on this due to the excellent reviews. Couldn’t find it in stores so ordered from Amazon. It works as described. Used it to seal tile backsplashes in kitchen, bathroom showers & tile floors in 80% of our new home. It doesn’t change the color or finish of the tile or grout. Really happy with it.
