Before you paint any surface, it has to be made ready to accept the paint. How to prepare walls before painting them requires well-planned preparation, which will make all the difference. With the right tools, you can make a room look totally new. You can’t just apply paint to a wall which already has paint on it. Before you prepare a wall for painting, you will want to take steps to protect your floors and furniture from splattered paint. Remove as much furniture from the room to be painted as possible and lay down paper or canvas drop clothes to protect the floors.
Start surveying your walls for dents, holes, and cracks, as these will need to be filled in to get an even surface. By using a putty knife you can also remove loose or scaling paint and then sand the paint edges to ensure a smooth surface. Wallpaper can be removed with special solutions from your hardware store. Most of the newer vinyl-type wallpapers can simply be peeled off. They will, however, leave a sticky residue, which can be removed with a sponge and warm water. Some of the older types of wallpaper may require coarse sand paper. The surface should be cleaned thoroughly, and once the wall is dry it should be resealed with an oil-based sealer. How to prepare walls before painting them will take the best part of a day.
How to prepare walls before painting them will be made easier by following these easy steps:
- Remove as much furniture from the room as possible
- Check for cracks and dents and fill them. Prime the repaired areas according to manufacturer’s directions. This is to ensure that the paint will adhere well and to also prevent future peeling. Check advice and tips for priming unpainted wood, as this may require a different type of primer.
- If you are re-painting walls you may not need to put on primer first, unless, of course, you are making a paint change from a dark paint color to a lighter shade.
- When you apply over a porous surface, mix with up to 20% water as this will seal the surface and also promote adhesion.
- After fixing flaws, wash down the walls with warm water and soap to remove grease and dirt
- A previous paint job may be peeling and you will need to remove it. Scrape the flaking paint with a scraper.
- This is important because flaking paint means the new paint won’t adhere. Once the flaking paint is removed, smooth the edges with medium sandpaper. Make sure, because in some instances you will need to scrape the entire area. Sometimes an electric stripper can help to make completion of the job quicker.
- Wash the entire surface with sugar soap before painting, you can protect wall trim with painters tape. If you opt not to mask around windows and doors, you can minimize the risk of paint spattering by using a paint shield which can be bought from your local paint dealer.
- Make sure that all your tins of paint are exactly the same color, stir the paint in the tin thoroughly before use
and apply two coats. Remember that by taking short cuts and using low-quality paintbrushes and paint can cost more in remedial work.
