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.
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, baseboards & 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.
Foam rollers are not recommended for normal latex paints as their spongy texture creates air bubbles in the paint film which can then burst, leaving a cratered, orange peel effect.
