If you’re painting over a glossy surface, it’s hard for the paint to adhere without the use of primer. If your walls have previously been covered with high-gloss or enamel paint, you will almost certainly need to apply a primer paint before you start painting and may even need to gently sand the surface before priming if it is very high-gloss. So if you could relate to this situation, just use an oil primer. By hearing the name, you could guess that it’s an oil-based primer. But it is an all in one solution for all old plastered walls. The mist coat was too neat meaning what little water there was is absorbed leaving the vinyl element of the paint on the surface of the plaster instead of actually soaking into the plaster evenly. 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. And now you see emerging little bumps and uneven surfaces. Which creates an unattractive look that you would not want at all.
