Product Information

If your colour choice is much darker or lighter than the original, apply a primer to help your new paint colour adhere better to the surface. 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.

This dead wood must be completely removed by rubbing it down to new sound wood. If outside, the wood can then be primed with Weathershield Exterior Preservative Primer followed by the Weathershield Undercoat& Gloss. Rotten wood Cause There are a variety of undercoat options available in the UK, with water-based and oil-based choices, and others designed around specific surfaces. Almost all undercoats will include primers, meaning that they can fully prepare a surface for painting. Oil-Based Undercoat Paint undercoat also protect your walls and surfaces and prepare them for the top coat, providing a neutral base for you to apply any colour, however bold it may be. Primer paint is essential if you're changing a colour scheme from a dark shade to something lighter, helping to show your topcoats true colour while keeping it vibrant for longer. 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.Ensure no rain is forecast as the paint is only weather-proof when dry, and get to work on day when the temperature is between 8 and 25 degrees Celsius.

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 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.

It can then be re-painted in your chosen finish. 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.
