Basecoat

This is also called sealer and has the following functions: 1) filling the wood pores – 2) allowing sanding, preserving the item colour – 3) realising a good bonding of any other basecoats or of the topcoat, thanks to “micro-streaks” caused by sanding.
A properly chosen and applied basecoat is critical for the final result of the entire coating system. Based on the user’s needs and on the desired result, it is possible to apply one or more basecoats. A basecoat may be single-component (as with nitrocellulose and waterborne ones), two-component (as with polyurethane ones) and multi-component (as with polyester ones).
