Use guide

Dilute RJ-WP19 with organic solvent such as mineral spirits, methyl benzene, acetic ether or petroleum solvent. Solvents with flash point higher than 60℃ are more recommended. RJ-WP19 can be diluted with a weight ratio of 1:1-1:12( for wood product we suggest dilute RJ-WP19 with a weight ratio of 1:1-5, heat treatment will accelerate the reaction).RJ-WP19 can also be used directly without dilution,when used directly, it has deeper penetration depth and good waterproof effect, but the color of the substrate surface is deepened.

Spray or brush twice or more on substrates, or impregnate substrates into solution for few minutes. Fully cured treated substrate for few days under room temperature, a high temperature would be helpful to accelerate the reaction.
