DIY - How to Prepare Your Wall For Painting
Having made the decision to paint your own walls there is no getting around the truth. If you want a professional looking finish there are no short cuts. Just like building a house on solid foundations, preparing your wall is the most important part. It doesn't matter how well you can paint, or what paint you use. This is even more vital if you are using enamel based paint. So let's get started.
Step 1
Remove any coverings that are on the wall. Light switch coverings, door lock sets and electrical outlets. Make sure to keep the screws in a safe place so you can find them again. If you find there are some coverings that you can't remove don't worry too much, they can be masked over.
Step 2
Washing the walls. Put down drop cloths to protect your flooring. All grease and grime needs to be thoroughly removed before painting. If you don't do this any grease marks will bleed through your new paint. Use something like TSP diluted in water for the main job. It is important to use a detergent that doesn't need rinsing and doesn't contain ammonia. You can make the job a little easier by using a mop on the wall, but be careful that you don't miss any spots. Stand back every now and then while the surface is still wet to make sure of this. If you have mold or mildew spots you may need to use a special spot cleaner on these areas before the main wash. Consider safety and wear a dust mask. Crayon marks come off easily with a little toothpaste.
Step 3
Scrape off any loose bits of paint with a scraper. Check for any holes and repair these with either plaster or a drywall compound. Wait until thoroughly dry then sand back lightly and add a little primer. Take care at this stage that you don't miss any spots or they will come back to haunt you.
Step 4
Sand back any glossy surfaces. This doesn't need to be sanded right back but certainly enough to take the gloss off. Make sure to remove any dust from sanding. A brush is usually sufficient. If you really hate sanding you could invest in a commercial gloss remover, but be sure to keep the room well ventilated and use according to the instructions.
Step 5
Use masking tape and plastic sheeting to cover any exposed fittings that couldn't be removed. Seal and or prime any new wood. See your local paint shop for advice on the best type to use with your wood and paint.
That is all there is to it! Your wall is now clean, mended, and ready for a fresh new coat of paint.
