White primer and “grip coat” for rigid, non-absorbent supports like: iron and non-ferrous metals (aluminium, brass, copper, zinc) which are not too mechanically stressed. polyester, acrylic glass, glass, fibre cement in interior and exterior (murals).
All supports should be completely free of oxide, dust and grease. Ferrous metals should be rust-free and initially treated with an expert rust protective priming. On an absorbent support, Uni-Primer can be applied with a brush or roller (an initial sizing with Lascaux Hydro Sealer is recommended). On non-absorbent supports a spray gun can be used for application as well. The first application should be diluted with approx.10-30 % water, depending on the absorption of the support.Lascaux Uni-Primer should not be used below the temperature of +8°C (+46°F).
