Graphenstone - GCS Interior Premium
Interior Wall Paint with Graphene Technology
Graphenstone's GCS Interior wall paint uses a combination of lime, silicate and natural minerals to create a beautiful matt paint. 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. 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 89 stunning colours from the GCS colour card (shown above). Also available in 980 colours from the NCS colour system (contact us for details).
The selected pigments used in the colour range are chosen for their light fastness, stability and resistance to temperature (colours suffixed with an (E) are less suited to exterior applications). The colours Adonis, Artic, Juniper, Moleskin, Indigo, Oxford and Periwinkle are not available in this finish. See GrafClean or GrafClean MidSheen instead.

Why do pots have Transparent, Medium or Pastel on them?
That simply refers to the base paint type that the pigments are added into to create the colour.

How to prep walls for painting
See the Graphenstone GCS Interior 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 GCS Interior Primer - for absorbent internal surfaces ie cement blocks, bricks, plaster etc.
- 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 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.
