Overview

Little Greene Wall Primer Sealer is a high-opacity, low-odour, microporous water-based primer. Ideal to prepare surfaces before painting, it seals and stabilises new, patched or friable walls and ceilings. Wall Primer Sealer regulates surface absorption to ensure a smooth, even finish without patchiness. It offers excellent adhesion to most existing finishes and is highly recommended to use under Little Greene water-based topcoats for both interior and exterior use.

Tinted Colour Information

Tinted paint is custom mixed in house at Next Day Paint using our Little Greene tinting machine. We mix the paint on site, which means we can offer our usual fast delivery with no extra delay.

Tinted Colour Match paints can't be cancelled or returned as they are tinted to order.

A tinted primer can be used to help obtain the true depth of colour for your top coat or to reduce the amount of coats required when a drastic colour change is occurring. A tinted primer will not necessarily be the same colour as your selected topcoat. It will be tinted towards the topcoat colour and generally lighter in shade. For example if your topcoat is black your primer may be a shade of grey. If you are unsure about when a tinted primer is required please contact us and we can advise further.

Preparation

Ensure the surface is clean, dry and free from dirt and grease.

Remove all imperfections and repair defects to achieve a smooth, sound surface

Previously Painted Surfaces:

• Remove loose or flaking paint and degrease with a suitable detergent (e.g. sugar soap), then rinse with clean water.
• Sand with medium-grade paper to create a smooth, keyed surface, feathering edges where paint has been removed.
• Make any repair required, sand and apply Wall Primer Sealer to exposed surface as appropriate.

New Plaster Walls:

• Allow skim plaster to dry for at least 4 weeks (6 months for full-depth plaster).
• >The primer coat may need to be thinned 5–25% (v/v) with clean water if the substrate is excessively porous.
• Cut in using the same dilution.
• For new, fully plastered walls, allow at least six months for the plaster to thoroughly dry before painting.

Existing Plaster Walls:

• Lightly wash to remove dust or laitance.
• The primer coat may need to be thinned 5–25% (v/v) with clean water if the substrate is excessively porous.

Not recommended for painting lime or other natural plaster.

Always follow manufacturer's instructions found on the packaging

Application

Always test a small area of the surface to be painted to ensure you are happy with the finished results

• Stir thoroughly before use.
• Do not apply below 8°C, or externally if rain or frost is expected during application or drying.
• Apply generously for a smooth, even finish, avoiding runs or sags.
• Lightly sand between coats to remove dust and imperfections for a smooth, professional finish.

For brush application:

• Use a high-quality synthetic brush suited to the project. Condition new brushes by washing and drying with a lint-free cloth.
• Avoid dipping the brush too deep or overloading with paint.
• Apply in even strokes, maintaining a wet edge.
• Keep final strokes in one direction and avoid re-working once paint starts to dry to prevent lap marks.

For roller application:

• Use a short-nap wool blend sleeve for smooth surfaces; increase nap for textured areas.
• Maintain a wet edge and consistent stroke direction. Do not over-roll drying paint to prevent lap marks.

For sprayer application:

• Conventional: Thin up to 40% (v/v) water. Tip: 1.60–2.00 mm (62–78 thou). Air pressure: 0.28–0.41 MPa (40–60 psi).
• Airless: Thin up to 20% (v/v) water. Tip: 0.28–0.54 mm (11–21 thou). Pressure: 12.6–19.6 MPa (1800–2800 psi).

Always follow manufacturer's instructions found on the packaging
