Application method

Brush, roller or airless, nozzles 19 – 21, 180 - 220 bar To ensure the optimum layer thickness, we recommend to apply the paint in two layers. Always make a test coat to ensure the compatibility of product and surface. It is recommended to maintain coated roofs with a treatment with Iso A-Clean every second year – in order to keep the surface nice and clean.

Drying time The drying time for wet layer thickness 200 µm 20° C / 65 % RH: Touchdry after ~2 hours. Recoatable after ~4 hours. Fully cured after ~24 hours. The drying time and time for recoating depend on layer thickness, temperature, relative air humidity, and air circulation.

Pretreatment/cleaning The roof must be cleaned thoroughly using high-pressure and Iso A-Clean. It is advantageous to prime fibre cement roofs with Eternit Primer in order to obtain a durable surface (see TDS). The surface must be clean, dry and durable.
