SURFACE PREPARATION

Surface preparation is very important so that epoxy paint can show expected performance. The surfaces to be primed should be cleaned of all kinds of rust, rolling crust, dirt, dust, oil and grease. It is especially recommended to sand blasting at least Sa 2 ½ degrees according to Swedish standard SIS 05 59 00 for surface cleaning. Abrasives should be used that provides Surface roughness Medium G 30-85 micron degree iso 8503-2.

MIXING PREPARATION

A and B component should be mixed with a low speed mixer for at least 3-4 minutes until a homogenous mixture is obtained by paying attention to mixture ratios. It is ready for application after mixing.>

COATING SYSTEM

The prepared mixture must first be applied to the bolt heads, welding seams and sharp edges as two coats. Then the process is completed by applying coal tar to give a dry film of 250 microns in 2 transverse coats to the entire surface. After application, the uncoated pores should be repaired by visual inspection.

APPLICATION CONDITIONS

*Avoid applications under 10°C and in very humid environments.
