Exterior Wall Paint

Graphenstone's GrafClean mineral paint uses a revolutionary natural vegetable resin and graphene technology to create an outstanding modern mineral paint that can be used both inside and outside. It can be applied to most surfaces including, plaster, gypsum, old paints, unpainted wallpaper, brick, wood, tiles and metal.

This very low VOC paint dries to an attractive ultra matt finish.

Grafclean performs more like an acrylic paint. It is a washable wall paint making it perfect for use in modern buildings, contemporary interiors, kitchens, bathrooms, hallways and other "high traffic" areas. It is recommended too for application in construction, specifically concrete as it is certified for moisture control in concrete surface protection systems (EN 1504-2).

With an exceptionally high solid content (up to 70%) it offers fantastic coverage.

The selected pigments used in the colour range are chosen for their light fastness, stability and resistance to temperature and weather. However colours suffixed with an (E) are less suited to exterior applications.

How to prep walls for painting

See the GrafClean (White) Technical Data Sheet for full details, however in brief:

For all surfaces

  • Ensure the substrate is dry, sound and clean.
  • If the substrate has salt deposits, brush and apply Graphenstone Neutralysal Premium
  • If the substrate contains a high moisture level, apply Graphenstone StopWater Premium

For previously painted walls

  • When applying over glossy paint, sand the surface lightly to create a "key".
  • Remove flaking and unstable paint. Create a uniform surface with Graphenstone Filler Primer

For unpainted surfaces

You can prime walls with:

  • Graphenstone Nevada Ultra - economical breathable primer.
  • Graphenstone Minerseal Premium - for very absorbent surfaces ie clay, adobe, rammed earth etc and for consolidating dusty mineral surfaces.
  • Graphenstone Four2Four Premium  - for wood, metal or non porous surfaces such as ceramic tiles.

How to prepare Graphenstone GrafClean paint

  • Stir and dilute with water to 10-15% of the product weight (150-200 ml of water per litre of product approx.), ensure a homogeneous mixture. Avoid excessive shaking to minimize bubbles. 
  • Apply 2 or 3 coats evenly  by roller, brush or airless spray gun.
  • Note: an excess of product by layers can generate micro-cracks.
