Product Information
Data Sheet

Should you need to do some repair work before getting down to painting, Earthborn Casein Filler is the perfect complement to Earthborn environmentally friendly wall and ceiling paints.

Our Casein Filler is based on the natural milk protein casein and white lime which uses less energy to make because being titanium dioxide free. This means it has a smaller carbon footprint than most other fillers.

Suitable for interior or exterior use. Supplied in powder form for mixing as required, you can even create coloured filler by mixing it with your choice of Earthborn Pigment.

Note: As the Casein Filler contains lime, it needs to be allowed to cure before painting. This is normally 4 weeks.

Drying Time 4 – 8 hours. Sand after 8 hours.

Sizes 2kg, 500g

Approx coverage 1.5 kg per m² per mm of thickness of coating.

Colours on screen may vary from actual paint. Slight variations in colour can occur between batches and finishes; the substrate and texture of the surface can also change the appearance of the final colour, as can lighting.

Advice is given in good faith but without warranty as methods of application and site conditions are outside of our control.
