Product Description

Exterior Wall Paint with Graphene Technology

Graphenstone's GCS Exterior wall paint uses a combination of lime, silicate and natural minerals to create a beautiful matt paint. It can be applied to all surfaces common in construction including mortar, brick, concrete old paints etc. It can even be used on wood and metal when substrates are primed with Four2Four primer.

This very low VOC paint dries to an attractive ultra matt finish. It is the perfect partner for restoration, heritage and listed properties as it allows the building to breathe.

The combination of natural lime with graphene produces a very strong and hardwearing paint with all the benefits of a natural lime paint giving you superb air quality inside your home, maintaining the breathability, sustainability and health of the building.

Available in White and 43 stunning colours from the GCS colour card (shown above). 

The selected pigments used in the colour range are chosen for their light fastness, stability and resistance to temperature.

How to prep walls for painting

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

How to prepare Graphenstone GCS Interior paint

  • Stir and dilute with water to 10-15% of the product weight (150-200 ml of water per liter 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.
