Description

TUFINEIN Rubber Liquid Waterproof Coating is a newly upgraded single- component, moisture-curing elastic waterproof coating, suitable for various building surfaces and roof substrates. The coating cures upon contact with atmospheric moisture to form a durable elastic rubber waterproof protective membrane. 1. It possesses long-term stability, exhibiting crack resistance at low temperatures, heat aging resistance, excellent self-leveling properties, strong bonding force, and high adhesion. 2. With outstanding toughness and elongation, it effectively fills fine cracks and resists substrate deformation as well as wind and rain impact. 3. The waterproof membrane demonstrates superior water-repellent performance, capable of long-term immersion in low water pressure areas. 4. The effective operating temperature range after curing is -40°C to 80°C (-40°F to 176°F), ensuring reliability in extreme cold and heat without weather concerns. The product can be applied at temperatures above -10°C (14°F) during winter.

  • Chimney coating
Color: Neutral Gray Size: 53 OZ
This product worked great on my large masonry chimney on my home . I put on one coat with the included mesh on the seams and did two coats on the whole surface afterwards and dried perfectly and looks great and will hopefully last for many years !

  • Dries quickly so be fast
Color: Neutral Gray Size: 53 OZ
Great stuff but be sure to use it all at once if you can. It forms a skin even sealed up and this has to be removed out you will not get a smooth finish. Seems to be very tough as a flooring surface

It goes on thick, and I got 1 coat on my 2 axle camper. I like it, I should probably get another one to coat it really well.
