Graphenstone Naturcolor Interior Matt

Graphenstone Naturcolor Interior Matt can be used as a finish for large decorating projects and rooms that need less frequent cleaning. It can also be diluted as a mist coat to prepare new plaster and other absorbent mineral surfaces, or used to help cover strong colours before applying a decorative topcoat.

Suitability

Suitable for interior walls and ceilings made from gypsum and lime plaster, plasterboard, drywall, brick and compatible prefabricated boards. It can also be applied to correctly prepared, previously painted or repaired surfaces.

For busy areas where surfaces may need more frequent cleaning, consider Graphenstone GrafClean Matt as an alternative.

Surfaces should be clean, dry, sound and free from dust, dirt, grease and other contaminants that could affect adhesion. Graphenstone Naturcolor Interior Matt can be applied to new or previously painted plaster, plasterboard, drywall, brick, repaired surfaces and compatible prefabricated boards, provided they are correctly prepared.

• Remove any loose, flaking or poorly adhered paint and clean the surface thoroughly.
• Take extra care when removing paint applied before the 1960s, as it may contain lead. Seek professional advice if you are unsure.
• Rake out cracks and fill holes and surface imperfections with a suitable filler.
• Allow new plaster and other mineral surfaces to cure for at least 28 days before painting.
• Lightly sand glossy, satin or particularly smooth surfaces to provide a key, then remove all sanding dust.
• Apply Graphenstone Ambient Primer L42 to absorbent mineral surfaces where required. Prime plasterboard and spot-prime filled or repaired areas to help produce an even finish.
• Prime wood, metal and other non-porous surfaces with Graphenstone Four2Four.
• Treat any mould, mildew or other organic growth with a suitable mould remover, for instance Barrettine Mould and Mildew Cleaner then allow the surface to dry completely.

We recommend trialing a test area before starting your project to check suitability and compatibility. Follow the manufacturer's instructions on the tin at all times.

Apply when the surrounding air and surface temperatures are between 7°C and 35°C and relative humidity is below 80%. Choose a surface away from direct sunlight and allow any sun-warmed areas to cool before painting.

When using more than one container of the same colour or paint from different batches, combine and mix them before application to help maintain an even colour across the complete surface.

• Shake the container before opening, then stir the paint thoroughly before and periodically during application. Avoid excessive mixing as this can introduce air bubbles.
• Adjust the consistency with clean water where required:
• Brush or roller application: Dilute with 10% to 15% clean water.
• Mist coat application: Dilute with up to 20% clean water.
• Spray application: Dilute with 15% to 20% clean water.
• Apply 2 or 3 even coats using a brush, medium-pile roller, such as Osmo Premium Roller, Brush and Tray Set or suitable airless spray equipment.
• Work methodically in manageable sections, maintaining a wet edge to reduce visible joins and lap marks.
• When painting walls, cut in and roll one wall at a time. Use the same dilution rate throughout and roll close to the edges to minimise picture framing.
• Spread the paint evenly and avoid applying overly thick coats, as excess paint may affect curing times and cause fine surface cracking.
• Allow approximately 2 to 4 hours between coats and around 24 hours for the paint to dry fully.
• Clean brushes, rollers and spray equipment with warm water immediately after use.

Although Graphenstone Naturcolor Interior Matt is fully dry after approximately 24 hours, it continues to harden for around 30 days. Protect the painted surface from water, condensation and splashes for the first 4 to 5 days, particularly in kitchens and bathrooms. Avoid rubbing, washing or cleaning the finish until it has fully cured.

Regular Cleaning

Once fully cured, wipe away everyday marks with a soft, damp cloth. Use a mild soapy solution for more persistent dirt, taking care to avoid abrasive cleaners, scouring pads and excessive scrubbing.

Repairs

Clean the affected area and lightly sand any damaged or uneven edges. Remove the sanding dust, prime exposed or repaired surfaces where required and apply Graphenstone Naturcolor Interior Matt in thin, even coats. Allow each coat to dry fully before applying the next.

Here are some of the more commonly asked questions and answers about Graphenstone NaturColor Interior Matt.

What is a contract emulsion?

A contract emulsion is designed for efficient application across large interior areas, including new-build, renovation and commercial decorating projects. Graphenstone Naturcolor Interior Matt is particularly suited to walls and ceilings in rooms with low levels of traffic.

What is the difference between Graphenstone Naturcolor Interior Matt and GrafClean Matt?

NaturColor Interior Matt is a breathable contract emulsion intended for large interior areas and rooms with low levels of traffic. GrafClean Matt provides greater resistance to stains, wear and regular cleaning, making it more suitable for busy or frequently used rooms.

Can Graphenstone Naturcolor Interior Matt be used on walls and ceilings?

Yes. It can be applied to correctly prepared interior walls and ceilings made from lime and gypsum plaster, plasterboard, drywall, brick and compatible prefabricated boards. It is also suitable for previously painted and repaired surfaces.

Can Graphenstone Naturcolor Interior Matt be used as a mist coat?

Yes. Naturcolor Interior Matt can be diluted with up to 20% clean water for use as a mist coat on new plaster and other absorbent mineral surfaces. New mineral surfaces should be allowed to cure for at least 28 days before painting.

Is Graphenstone Naturcolor Interior Matt suitable for kitchens and bathrooms?

It can be used in kitchens and bathrooms as a mist coat, but its contract formulation is best suited to areas with lower levels of traffic and cleaning. For frequently cleaned or heavily used surfaces, Graphenstone GrafClean Matt provides a more durable alternative. Naturcolor should not be applied to surfaces in permanent contact with water.

How many coats of Graphenstone Naturcolor Interior Matt are required?

Graphenstone recommends applying 1-2 thin, even coats to achieve consistent colour and coverage. Allow approximately 2-4 hours between coats and around 24 hours for the paint to dry fully, depending on temperature and humidity.

Is Graphenstone Naturcolor Interior Matt washable?

Once fully cured, Naturcolor Interior Matt achieves Class 2 wet-scrub resistance under EN ISO 11998 and can be wiped with a soft, damp cloth. Allow approximately 30 days for the finish to cure fully and avoid abrasive cleaners, scouring pads and excessive scrubbing.
