GP PRIMER

Application

All surfaces should be smooth, clean, sound and free from oil, grease, condensation and other contamination. Product may be applied to ‘green’ concrete and damp surfaces. The minimum ambient temperature for application is 0°C; it is not recommended to apply GP^® Primer at temperatures below this as advertised drying times will not be achieved.

GP^® Primer is recommended to be brush or roller applied, avoid pouring directly onto a horizontal surface. This may cause puddling during application and increase drying time. GP^® Primer should not need to be thinned if recommended storage conditions have been maintained.

Coverage rates depend on porosity of surface:

• Porous surfaces (e.g. concrete, wood): 6-8 m2/litre
• Non-porous surfaces (e.g. steel): 11m2/litre

GP^® Primer is designed to be effective as a single cost application.

If applying to metal, ensure the surface is well prepared in advance. Wire brush off any rust and ensure clean and dry. Where long-term protection is required, treat with a rust-inhibitive product. Consult the Technical Department for advice on compatibility prior to application if unsure. 

Keep primed areas clean and dust-free so far as possible prior to membrane application. Areas that accumulate significant amounts of dust or dirt must be re-primed before the membrane application, bonding performance will be compromised by debris.

For cleaning tools use hydrocarbon-based solvent such as White Spirit. Xylene, Toluene and Acetone are also effective.
