Spray Paint Finishing



We are looking for a Paint Spray with very high gloss of 90%. How can I obtain this gloss and scratches resistance on MDF Board? What are the layers involved? Approximate what is the time needed to achieve this layer? Can it be accerated with Oven?

To obtain a 90% sheen or better on MDF you should:

a . use a polyester primer coat. (I get mine from Italy)

b. Sand the polyester with 180 through 320 grit or equivelent.

c. Assuming you asked for an opaque finish, use a quality lacquer paint for color. If you need a clear finish, use a polyester sealer/clear lacquer. Make your color even.

d. Topcoat with a automotive type urethane clearcoat that is compatible with lacquer; or use a basecoat/clearcoat combo. Polyester accepts just about anything you can spray on it.

e. Good enough? If not, then wet-sand the clear using mineral spirits as a lube. When all the dust nibs are gone,then polish with any good auto compound and wax. This system has worked for me in many variations over the years. The polyester was recommended by famed piano finisher Donald Stienert in Fine Woodworking.

Good luck!
