SUBSTRATE PREPARATION

For maximum performance, all surfaces to be over coated must be clean, dry and free from contaminants. Fresh water wash and degrease according to SSPC – SP1 solvent cleaning.

For best results, blast clean to a minimum of Sa2½, near white metal. Hand and power tool cleaning to a minimum of St 2 or St 3.

APPLICATION

Apply in one coat, by brush, roller or spray, with a consumption of 0.09–0.14 kg/m² per coat depending upon surface roughness and absorption.
