Bostik Plasterer’s Stabilising Primer, No Mixing, Easy to Apply, Colour: Green, 10L

Product Information

Using a primer paint is a good idea if your surface is porous. Walls can become porous when moisture in the air is absorbed. Walls in kitchens and bathrooms are more likely to become porous than other rooms because of the increased humidity and moisture that builds in the air. Priming these walls before painting stops the paint being absorbed into the wall. Spirit-based primer can be used on indoor and outdoor surfaces. The shellac-based primer is great for sealing over stains and odour on interior walls and ceilings, and can be used for spot-priming exterior surfaces. Apply with a brush, roller, or spray. Metal Specific Primers Universal wood/metal primers can be used on new wood, masonry, metal, and plaster, inside and outside. Apply with a brush and clean with white spirit afterwards. Primers for Plaster It’s imperative to use a primer on bare plaster. This image shows what happens if you paint straight onto bare plaster without priming with a mist coat first. So from here just choose the right oil-based primer for you. We prefer oil-based ones mostly because they can help in binding, sealing, and stain removal. Binding Primers

Painting the metal surfaces in your home and garden – think garden gates, garage doors, and aluminium window frames – is a good way to refresh your space. Before you start painting your metal surfaces, you will need to prime them to help the paint adhere to the smooth metal surface. The other main function of PVA is that it’s used as a primer. We seal all the walls with PVA (not needed on plasterboard), to make sure we can get a decent finish. It helps bond the plaster to the walls and also gives us time.

Using PVA for bonding

If your walls are stained, you will need to use a primer paint to cover the stain and to stop it affecting the new paint. Spills and leaks happen and whilst it can be frustrating, it doesn’t have to mean the end of a professional-quality paint finish. To ensure an even result, we recommend applying primer paint to the whole wall, not just the stain. This also applies for ceiling stains too. To make a mist coat simply add about 30-50% of water to your paint and mix well. Apply with a roller and brush and allow to dry completely before adding your main coat of paint.
