Drying: GCS interior dries in 2-4 hours between coats, and 24 hours until fully dried. Around 30 days until fully cured.
Coverage: Around 12-18m2 per Litre. We recommend diluting 10-15% with water before application for better coverage and easier application. Requires 2 coats.
If painting over mineral substrates, they must be at least 28 days old before application. The substrate must also be resistant to high alkalinity. If in doubt apply to a test area first, and do not apply to surfaces in constant contact with water.
Previously painted walls:
Over old glossy paint, sand surface to create a key for good adhesion.
Over old paint (standard normal paint), just remove unstable or flaking paint, then either prime with 10% diluted GCS interior to use as the primer, or use the Ambient Primer to homogenise the surface fro a uniform top colour. This does not change the breathability of the GCS interior.
How to prep GCS Interior prior to using
Open pot and give it a good stir. Ideally dilute with 10%-15% pf the product weight, which will be around 150ml to 200ml of water per litre of product). Avoid shaking to avoid bubbles.
Apply two to three even coat, with a roller, brush or airless spray gun.
Primer. If primer is required, use the Graphenstone L42 Ambient Primer.
