Product Information
Data Sheet

Earthborn’s Isolating Primer is designed to treat stubborn, dry stains before overpainting with water based paints such as Earthborn Claypaint or Earthborn Lifestyle Emulsion. It is a matt white paint that contains a stain inhibitor and is ideal for treating stains including crayon, graffiti, water stains, creosote, smoke stains, hand marks, asphalt etc. helping to prevent them from bleeding through the new paintwork.

With a water based formulation, Earthborn Isolating Primer is made from carefully selected, premium quality ingredients and is formulated to be less harmful to the user and the environment than competing products.

Please note: Isolating Primer is designed to isolate stains, so will not allow the areas to breathe where applied to.

Drying time: Touch dry in approximately 30 minutes depending on temperature and humidity. A second coat can be applied after 4 hours.

Approx coverage: Up to 14 m² per litre.
Coverage is approximate and dependent on surface properties

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.
