Systems Specifications Maintenance Repaint

Surface Preparation: No paint system will give optimum performance over poorly prepared surfaces. Painting over dirt, dust or contaminated surfaces is

wasteful in terms of time, materials and labour. The aim in preparation is to remove contamination, glossiness and defect of the surface in order to provide a physically sound and chemically clean surface.

Ensure surfaces are degreased and free of contamination using Protective Paints A925 - Metal degreaser (follow instructions as per data sheet).

Ensure surfaces are free from preparation debris and are clean and dry. Apply 1^st coat within 4 hours of abrasive blasting. Practical coverage is project dependent.

All corroless data sheets can be obtained by cicking on the links.

*General Metal Protection and Maintenance Schedule:

The main task of the protective coatings is to prevent or control corrosion. During its service life a protection coating system deteriorates

as a result of exposure to ultra violet light, moisture, fluctuating temperatures, chemicals, abrasion and many other possible factors.

It is thus recommended that a preventative maintenance schedule be followed to attain the optimum performance from the coating system.
