Nano waterproof coating RJ-WP21※MSDS Download ※TDS Download Inquiry
RJ-WP21 is a new generation solvent based water repellent developed by nano technology, it can impart super hydrophobic water repellency to various substrates.
After nature stone is treated by RJ-WP21 and fully cured, contact angle between water drop and substrate can reach 150°or more. RJ-WP21 will impart excellent lotus effect and self-cleaning function to the substrates.

● All kinds of concrete include aerated concrete.
● Highway, airport runway, bridge & tunnel.
● Cement mortar, lime mortar & cement fiber boards.
● Interior or exterior wall
1. Dilute RJ-WP21 with organic solvent such as petroleum solvent or solvent oils. RJ-WP21 should be diluted with a weight ratio of 1:20-1:25.
2. Spray or brush RJ-WP21 on substrates, or impregnate substrates into RJ-WP21 for few minutes. 1 liter RJ-WP21 can treat more than 10 m3.
3. Fully cured treated substrate for 1-3 days, no contact with water or fire. In summer tack-free time is only 2-3 hours, after that substrates will be water resistant, then 3 days later there will be super hydrophobic properties.
