Dulux 5092090 Primer & Undercoat Paint For Wood - 2.5L, White

Product Information

Intended for use with emulsion paints, water-based undercoats are vital in many cases for a smooth finish. Most of the options within the UK will also function as a primer, effectively offering protection for the underlying material and an adhesive surface for painting in a single coat. Acrylic Primer Undercoat Loss of gloss is normally only noticed with high gloss paint & varnishes. It is caused by the settling of dew or condensation on the paint shortly after application. This is often a problem when painting out of season, or in areas of high condensation like bathrooms. Putting it right When the surface is thoroughly dry the affected surface will need to be rubbed down using 'wet and dry' abrasive paper. It can then be re-coated. Begin by laying down a dust sheet underneath the area that you will be working in, to prevent any primer or paint spillages from staining your floor. Then clean the surface you will be working on with soap and a sponge, removing any algae, mould or surface coating, and allow the area to dry. Tape up any metal hardware such as handles or doorknobs with masking tape prior to priming and painting, to prevent stains and paint splatters. When the surface is thoroughly dry the affected surface will need to be rubbed down using 'wet and dry' abrasive paper. It can then be re-coated. This should only be done once the conditions improve or when the condensation problem is resolved.

When shopping in the UK, most undercoat options you find will also work as primers, allowing you to fully prepare a surface with one coat.

Putting it right It is important to seal the original stain by applying a coat of Polycell Stain Stop prior to re-decorating.

Resins present in knots causing light coloured paints to discolour or even flake. Resin bleed and flaking is a common problem where dark colours are used on south facing elevations. This is because dark colours absorb more heat than light colours.Affected areas should be treated with Weathershield Multi-Surface Fungicidal Wash. Once rinsed and allowed to dry it can be over coated with your favourite Weathershield Masonry Paint. This is caused by painting over contaminated surfaces such as wax, oil or polish. The paint cannot adhere to the surface and draws away leaving unpainted areas. This can also be caused by contamination on the brush. Putting it right This is caused usually by a wearing away of the paint film by weathering or could be evidence of salts coming out of the surface. Putting it right

The affected area should be brushed down with a stiff bristle brush to remove as much powdery material as possible before applying a coat of Weathershield Exterior Stabilising Primer. If the powder is due to salts/efflorescence then the surface should be wiped with a dry cloth to exhaust the salts before coating with Dulux Trade Alkali Resisting primer to eliminate staining. It can then be re-painted in your chosen finish. You will need to rub down using 'wet and dry' abrasive paper using water with a little detergent added. The surface should then be rinsed and allowed to dry before repainting. If this is impractical due to the size of area affected the area could be horizontally lined with lining paper and then repainted.

Oil-based undercoat paints are for use with oil-based finishing paints. While these paints were traditionally the choice of professionals, advances in water-based options mean that today many will use both, or have moved to water-based entirely. It’s worth keeping in mind that oil-based undercoat paints will release volatile organic compounds (VOCs) while drying, which can be dangerous. Ensuring adequate ventilation is crucial, with many opting to use water-based paints internally. Water-Based UndercoatApplication : Brush or roller only. For health and safety reasons related to all solvent-based paints, spray application is not recommended. STIR THOROUGHLY BEFORE USE. Apply 1 coat of the appropriate coloured Dulux Trade Undercoat, followed by 1 or 2 coats of Dulux Trade High Gloss. Allow a minimum of 6 hours for the undercoat to dry before applying the Gloss finish. Where a second coat of Dulux Trade High Gloss is required, allow a minimum of 16 hours between coats.
