Application

The substrate must be dry, firm, well adhered, even and free of any impurities that could hinder the perfect bonding of the product. Mineral substrates must be at least 28 days old.

Ensure the substrate to be painted is thoroughly cleaned with any organic growth and/or other impurities removed by thorough cleaning using specific products for this purpose.

Depending on the nature of the surface, the actions prior to application of the paint vary as follows:

• Old glossy or satin paints and putties: clean the surface and sand softly.
• Absorbent substrates (e.g. concrete block or brick): apply Graphenstone Ambient Primer Premium.
• If the substrate is wood, metal (without corrosion or oxidation) or non-porous (e.g. glazed tiles, phenolic panel, epoxy or polyurethane paints): apply Graphenstone Four2Four Premium.

Shake and dilute the product with water using 10-15% per litre (Approx. 150-200ml water p/L or 19-26 fl. oz. of water p/Gal of paint). Ensure good mixing. Avoid excessive shaking to minimise bubble occlusion.

On transparent bases, or intense colours, dilute with water at 5-10% of the weight of the product (approx. 100-150 ml of water per litre of product).

The recommended application method is by Roller, Brush or Airless Spray.
