Quick tips

How to clean your brushes after painting

To extend the life of your brushes and rollers, it is essential to clean them thoroughly and allow them to dry before storing.

How you clean brushes depends on the type of paint you have been using. All brushes and rollers that have been used with water-based paints should be rinsed in cold water and then washed in warm water with a little detergent. Brushes which have been used to apply solvent based paints should be cleaned with Polycell Brush Cleaner and then washed in warm water with a little detergent added. Rinse brushes in clean water, shake off excess water and wrap in a piece of clean paper towel and secure with masking tape. The brush will then dry back to its original shape, ready for the next job. Brushes should be stored flat. Standing brushes on their ends will bend the bristles and spoil them. Rollers should be stored hanging up to avoid crushing the pile.

Can I paint plastic garden furniture?

As garden furniture is made of a very smooth plastic and it is flexible we do not recommend painting it.

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.

How should I paint a radiator?

Before painting a radiator it is important to turn it off and allow it to cool down. Rub the surface down with 'wet and dry' abrasive paper and warm water with a little detergent added. Rinse, clean and dry. Any bare areas should be primed with Dulux Metal Primer. This will provide protection from rust and provide excellent adhesion for subsequent coats. You can then paint the radiator with solvent-based paints like Dulux Satinwood or Dulux Non-Drip Gloss. These paints all come in a wide range of colours allowing you to paint the radiator in a matching colour to the walls therefore helping to disguise it.

Once painted you should allow the paint to fully dry before turning the radiator on again. When you do so for the first time you may experience a paint smell - this is normal and will quickly disappear.

How do I paint new plaster?

New plaster should be sealed with Dulux Plaster Sealer when the plaster is completely dry. A plaster Skim will take approximately 2 - 3 weeks to dry, whereas a full plaster will take around 6 months to dry.
