Proper surface preparation
Before applying the lacquer, surfaces must be properly prepared. For unpainted wood, OSB or multiplex panels, remove dust and grease with a mixture of water and ammonia (1 part ammonia to 9 parts water).
Painted woods in good condition require thorough cleaning, while those with flaking coats should be scraped and sanded after degreasing. Melamine and wall tiles require cleaning with an abrasive sponge and degreaser.

Material selection and application

Use foam or mohair rollers for even application. Before you start, make sure you have all your materials to hand and mix the paint thoroughly.
