Coo-Var Undercoat is an oil based, high opacity undercoat with good flow characteristics. Ideal for use as a foundation coating or when a colour change is required. Ensures the subsequent topcoat is as effective as possible.

Surface Preparation

All surfaces should be clean, dry, sound and free from contaminants. Wood should be sanded prior to coating to ensure an adequate "key" is produced. Apply direct to abraded GRP. Existing painted surfaces should be cleaned, degreased and sanded to ensure an adequate "key" is produced. Remove all loose, flaking material and treat bare areas as new substrate then prepare accordingly.

Application Conditions

As dictated by normal good painting practice. Care must be taken during application that the temperature is above the dew point to avoid any contamination. In confined spaces, provide adequate ventilation during application and drying.

Preceding Coat

Direct to wood and GRP, use Coo-Var Zinc Phosphate Primer on ferrous metals.
