What Customers Are Saying

Customers overwhelmingly praise this thinset mortar for exceptional ease of use and reliable adhesion, particularly with large-format tiles. Reviewers consistently highlight smooth, lump-free mixing, effortless application, and extended working time before setting. The product excels at holding tiles securely on walls and floors, including porcelain and natural stone in high-moisture areas like bathrooms. Many users report deep loyalty, repeatedly choosing it for projects. A few mention isolated adhesion issues, but these are universally attributed to improper installation or substrate preparation rather than product failure. Overall, customers consider it a dependable, high-quality choice for both beginners and experienced installers.

Be Aware this product contains Hexavalent chromium

Hexavalent chromium is a toxic chemical found in Portland cements and mortars that can cause severe allergic contact dermatitis if it gets on you. I did not know about this and now I have horribly itchy skin all over my body that I'm told will never go away. Please use heavy nitril gloves and wash off any mortar that gets on your skin immediately. After cool water rinsing for 20 minutes use vinegar to neutralize the alkaline residue. It's no joke what it can do to you.
