Shrink Face (RC) the colors comes from the chemical reactive, from 3-6 times stain, the colors show natural from the inside of the wood, and because of the Tannin content is different in different part of the wood, the colors really show little bit variations with the same color tone. And we made the filler match very well of the wood color and the finish color.
The last coating we use water base,it is waterproof, it is pollution proof and it is very easy for maintenance.
