A beginners Guide to Painting Walls

By: Katie Brown

Here are the key steps to preparing a room for a new coat of paint or paper. Whatever type of surface you're going to tackle it must be clean, dry and smooth for the best results - preparation is the secret of a good-looking finish.

Time to complete job: Preparing a room for a new coat of paint or paper will take at least half a day, including filling and smoothing old plaster.

Approximate budget: The basic tools and materials should cost less than £20 for most rooms.

You will need:
Sugar soap
Bucket and sponge
Rubber gloves
Interior plaster filler
Decorator's sealant
Filling knife
Sanding block or electric sander
Dust sheets
Step ladder
Dust mask

Tip: Before to begin, always protect yourself by using a dust mask and your floor by laying down dust sheets.

Step 1: Ensure that the surface is smooth. Using a sanding block, or cork block with sanding paper attached and a flexible filling knife where necessary, remove all debris such as paint flakes. For more tips on stripping back paint, see Paint Stripping. If there is wallpaper on the walls this will need removing. For tips on doing this, see Stripping Wallpaper.

Step 2: Repairing damaged plaster Sometimes patches of old plaster become loose or cracked. Pick out the loose areas with your filling knife and repair the areas with plaster filler. Work methodically over the whole room to make sure you have treated all the damaged areas. When the filler is dry, use an electric sander or sanding block to smooth any rough areas of plaster and blend in the new repairs. Very powdery plasterwork or new bare plaster should be coated with a coat of plaster sealer. Depending on the size that requires repairing, you may need to patch it up. Patching up plaster is beyond the scope of this article but detail of how to do this can be found on the UKTV website. Tip: In order to ensure as nice a finish around the door frames and skirting boards as possible ensure that no cracks are present. Ensure that you remove any debris such as flaking pain and anything else that does not belong and then seal the gaps by carefully applying the decorators sealant.

Step 3: Cleaning Wash off any black mould with a solution of household bleach and leave to dry. Stains left by mould or tobacco use can quite easily be masked with anti damp paint or watered down unibond which are available at all hardware stores. Tip: It's essential to treat the cause of mould and damp patches before redecorating.

Step 4: Make a judgement call as to whether the esposed walls need to be covered with lining paper. If the walls have large repair patches or lots of tiny hairline cracks, covering with plain lining paper will provide a smooth base for paint or wallpaper. Hand this paper in the same that that you would hand regular wallpaper and then allow this paper to dry thoroughly over night. For more tips, see Wallpapering. And last but by no means leas, ensure that the surface is dirt and grease free by wiping down with sugar soap or hot water and washing up liquid. Don't forget to wash the ceiling as well if it's going to be decorated.
