Surface temperature shall always be at least 3°C above Dew Point. Do not expose the coated articles where there are chances of condensation on the surface.

Surface Preparation

All surfaces to be coated shall be dry and free from oil, grease, dust, dirt and any foreign matter that can adversely affect adhesion of coating. Solvent cleaning as per SSPC SP1 shall be conducted wherever necessary.

Recommended Surface Preparation

Surface shall be prepared by hand/power tool to achieve ST2 / ST3 standard of surface preparation as per ISO 8501-1. Any tightly adhering Old coating may remain on surface. For larger surface areas, abrasive blasting may be carried out to achieve Sa 2 as per ISO 8501-1.

Mixing a Liquid binder

Aqua ST AL is supplied in 2 parts, a liquid binder (Part A) and (Part B). Always mix liquid (Part B) into the liquid (Part A) while stirring. 75-100 RPM mixer is recommended.
