What Customers Say About This Product

I used this on my kitchen backsplash and it was easy to apply. The brush helped, but the formula is runny, so go slow. It’s been a few months and my grout still looks clean.

Applied this to my bathroom floor grout. It dried quickly as stated. I haven’t seen new stains yet, which is a good sign. The bottle size is just right for one room.

For small repair jobs, this is a handy product. The applicator is convenient. Note that it’s watery, so manage drips carefully to avoid extra cleanup on the tiles.

Mixed feelings. It does seem to help with water spots, but I had a leaky bottle which was messy. The protection is decent for the price on a small area.

Apply the sealer using the brush applicator directly onto clean, dry grout lines. Allow it to penetrate for a few minutes, then wipe any excess from the tile surfaces. Drying time is typically quick.

While this product is designed to provide stain resistance, some customer experiences vary. For best results, ensure grout is properly cleaned and dried before application, and consider a second coat for enhanced protection.
The included brush applicator is intended for direct application. The product has a watery consistency, so apply carefully to avoid drips and run-off onto surrounding tile surfaces.
