IS Isonit Non Reflective

IS Isonit Non Reflective

Product description

Isonit Non Reflective is a water dilutable roof coating especially suitable for cratered roofs of fibre cement. The special paint spreads the reflection of the sunlight resulting in the surface looking more evenly matt instead of appearing faded and pale. Isonit Non Reflective has a high covering strength and a short drying time. The coating is breathable (diffusion-open) and creates a water-repellent surface. Good flow and levelling properties. Strong and water-repellent surface. Light-fast and weather-stable. CE-marked (EN1504/2). Use: Cratered roofs of fibre cement (primed with Eternit Primer), concrete roof tiles, fibre cement slates, primed steel roofs. Not usable on clay tiles and natural slate.


Standard colours: Black, anthracite grey dark, red brown, dark brown, black blue. Other colours are available on demand.

Application details

The temperature must be between 8° C and 30° C and relative humidity <85 % RH.

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 (each with a layer thickness of 200 µm). If Eternit Primer is used, the right layer thickness can be obtained with only 1 layer of 300 µm. 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.

Technical data

Gloss 5

Spreading rate 2 - 4 m²/l

Drying time The drying time for wet layer thickness 200 µm 20° C / 65 % RH: Touchdry after ~1 hour. Recoatable after ~2 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.

Environment Avoid spillage into drains, water systems and soil. Destroy liquid waste according to the local regulations. Recycle or dispose of empty, dry cans in accordance with local regulations. VOC: Max. 40 g/l (Kat. A/c)
