Applied 2 coats of this and so far it's solved the problem. It's a nice thin paste consistency that doesn't run and is easy to apply with the little brush supplied - no good for a big job but fine for what I needed. It washes out easily in water. No unpleasant fumes. I'm pleased with it so far. ### ⭐⭐⭐⭐⭐ Amazing product, transparent when dry, saved old garden mosaic table top! 5* *by on Reviewed in the United Kingdom 25 June 2026* Wow! Saved 20 year old mosaic garden table top, use 2 coats for waterproofing, transparent when dry, waterproof. Apply with brush supplied for first coat and then go for bigger brush if you have large area to give 2nd coat to. In current heat it dried very quickly so was able to 2nd coat after 8 hours. 5* product. ### ⭐⭐⭐⭐ Water sealant *by on Reviewed in the United Kingdom 3 May 2026* Does what it says on the tin.
