![]() ![]() If this is impractical due to the size of area affected the area could be horizontally lined with lining paper and then repainted. The surface should then be rinsed and allowed to dry before repainting. You will need to rub down using 'wet and dry' abrasive paper using water with a little detergent added. Sometimes these craters dry to give an even film. When these bubbles burst craters are left on the film surface. Foaming happens when air gets into the wet paint film to create air bubbles. Long pile rollers must be wetted out properly. Sponge or foam rollers should be avoided with water-based paints. Using the wrong type of roller can cause foaming of a paint film. Once this is dried you can apply a full coat of Dulux emulsion. Use a coat of Dulux emulsion thinned 10-20% with clean water. You will need to prime the filler before painting to prevent subsequent coats being absorbed more rapidly than on other areas. Make sure that all filled areas are rubbed down smooth and level. Once rinsed and dried the area can be repainted.įiller shows through the paint. Putting it rightĪllow the surface to dry and then rub down using 'wet and dry' abrasive paper and a solution of warm water and detergent. This can also be caused by contamination on the brush. The paint cannot adhere to the surface and draws away leaving unpainted areas. This is caused by painting over contaminated surfaces such as wax, oil or polish. It is important to seal the original stain by applying a coat of Polycell Stain Stop prior to re-decorating. This is usually caused by contamination of the underlying surface by soluble stains. If large areas are involved it will be best to totally strip the surface back to a bare surface and start again. This is because dark colours absorb more heat than light colours.Īll loose material will have to be removed back to a firm edge, spot primed with the appropriate Dulux Primer, and then recoated with the appropriate product. Resin bleed and flaking is a common problem where dark colours are used on south facing elevations. Resins present in knots causing light coloured paints to discolour or even flake.Excessive movement of the substrate, such as joints, imposing stress on the paint film which can result in cracking which in turn lets in moisture, ultimately resulting in a flaking paint film.Polish residues on the surface, which impair the adhesion of the paint.Surface contamination such as dirt, oil, and grease.If the paint is applied over a powdery or friable surface.Moisture trapped beneath the surface of the paint film. ![]() This may be due to any of the following factors: ![]()
