Quick tips

Which brushes do I use for which job?

When selecting a brush it is important to consider the following areas: type of bristle; job to be completed & coating to be applied.

There are 2 types of bristle: synthetic and natural.

Synthetic bristles are very hard wearing, lasting up to 5 times as long as natural bristle brushes. As synthetic bristles do not absorb large amounts of water and swell up they do not cause tramlines to appear in the paint. Their structure produces a fine finish on all water-based paints.

Natural bristle has a structure that allows it to take and hold paint within the brush. In addition, the split ends of bristle brushes help to produce a fine finish with traditional solvent paints. However, they do not perform well with water-based paints like Dulux Once, or Quick Drying Satinwood.

Brushes come in many sizes. As a rule of thumb, the larger the area you are painting, the larger the brush that you should use. For walls a 2" or 3" brush is required for cutting in, whilst a 1" or 2" brush will give you more flexibility when painting doors, skirting boards & architraves.

What type of roller do I use?

Rollers are ideal for painting large areas, particularly ceilings. They are quick and easy to use. There are several types of roller to suit different paint jobs: foam, mohair or sheepskin, available in short, medium and long-pile. Your choice of roller really depends upon the sort of paint you are using. A short-pile mohair roller is suitable for applying silk emulsion. A medium-pile sheepskin roller is ideal for applying matt emulsion. Foam rollers are not recommended for normal emulsion paints as their spongy texture creates air bubbles in the paint film which can then burst, leaving a crated, orange peel effect.

Is there a right order to painting a room?

Generally when painting a room it is advisable to start at the top of the room and work down. The following is a typical sequence:

  1. Ceiling - Apply two full coats. Dulux Magic White is ideal for this purpose.
  2. Walls - Apply two full coats of your chosen Dulux emulsion, working away from natural light.
  3. Doors & skirting boards - Start with the windows to give them a full day to dry before closing them in the evening. Next paint the door & doorframe followed by the skirting.
I have removed wallpaper from my walls. How do I prepare them for painting?

Having removed wallpaper by scraping, the surface must be thoroughly washed down to remove all old paste and size. While the surface is still damp is the best time to fill all holes before painting. If the area is small then Polycell No Sanding Polyfilla is the ideal solution as it is dry in as little as 15 minutes. However, if the area is larger, use Polycell SmoothOver for Cracked & Damaged Walls. It offers a whole wall solution that covers cracks, dents, gouges, small holes and other problem features in one go, leaving them smooth and ready to paint after rubbing down

The wall can then be painted with any Dulux emulsion

When decorating it is important to remember to protect anything that you do not want to get covered in paint or dust. The best way to do this is to move all large items into the centre of the room and then cover with a clear plastic dust sheet. This is so anyone coming into the room will be able to see what is under the sheet and will help to avoid the risk of putting things on your precious items.

Now that we have finished preparing all the walls we can start to think about the order in which we paint the surfaces. First of all we start with the ceiling. This is so that any wet paint that may drop will only fall on an unpainted surface, which will be painted later.

Now the primer is dry it is time to choose an undercoat, which can be water based or solvent based. The idea of an undercoat is to fill any imperfections in the surface, such as grain marks.

When decorating any surface that has paint on it, the best way to start is by cleaning it down with sugar soap. Allow this to dry.

When it comes to decorating it is very important to choose a good quality brush. The first one I will show you is a synthetic brush. This is most suited for water-based materials as opposed to solvent because it doesn't absorb moisture.

When it comes to decorating large surfaces it is best to use a quality roller. You can get many different sizes and differing pile lengths - short, medium or long. The best way to choose the roller you need is to consider that a short pile is for very fine or flat surfaces.
