Surface Preparation
All surfaces to be coated should be clean, dry and free from contamination. Prior to paint application, all surfaces should be assessed and treated in accordance with ISO 8504:1992
Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.
Strict adherence to all cleanliness standards is essential for application of water-based coatings.

Abrasive Blast Cleaning
Abrasive blast clean if oxidation has occurred between blasting and application of Waterglass Anticorrosive, the surface should be reblasted to the specified visual standard.

Surface defects revealed by the blast cleaning process, should be ground, filled, or treated in the appropriate manner.


Waterglass Anticorrosive is supplied in 2 parts, a liquid binder base component (Part A) and a Powder component (Part B). Powder (Part B) should be slowly added to the Liquid Binder (Part A) while stirring with a mechanical mixer.

Material should be filtered prior to application and should be constantly agitated in the pot during spraying. Once the unit has been mixed it should be used within the working pot life specified.

Mix Ratio

1 part (Part A): 0.7 parts (Part B) by volume
1 part (Part A): 4 parts (Part B) by weight

Working Pot Life

8 hours at 20 °C (68 °F)

Spray: Conventional Spray Application: Use pressure fed spray gun – DeVilbiss
JGA558, AV651-D fluid tip, MB-4039-64 air cap set up, or equivalent with 75 psi
atomising pressure and air agitated pot pressure of 20 psi, according to length of
material line used.
