Paint  Brushing TechniquesTransfer sonic paint from the can into a paint kettle or any suitable container with a handle. Put the lid back on the can.

Dip the brush in the paint to about one third to one half of the depth of the bristles ЎЄ no more or paint will work its way up to the top of the bristles and from there to the handle. Estimate the area you’ll cover with one brushful and apply the paint in dabs about 60mm apart. Brush the paint out to produce an even coating, using both vertical and horizontal strokes. Finally, lay off the paint with light, vertical, upward strokes. Repeat the process, laying off the second area so that it merges into the wet edge of the first, and so on.

If the coating is uneven, you’re applying the paint too thin or not brushing it out enough. II the brush drags, you’re probably trying to spread the paint too thin. If the paint sags or runs, you’re applying it too thickly. Don’t try to correct mistakes which appear as the paint dries by brushing over them with fresh paint; the brush will drag off the surface film and just make matters worse. Wait until the paint has dried, rub down and repaint.

Before you use a new brush, stroke it vigorously back and forth across the palm of your hand, to remove as many loose bristles as possible. Even so, a few bristles are sure to appear in the paint when using a new brush. If you spot them right away, you can flick them off the paint with the tip of the brush. Otherwise, wait until the paint has dried, remove the bristles, rub down and repaint.

For windows, start by painting around the concealed edges of opening casements or sashes. Next, paint around the glass – use a cutting-in brush or, if you have difficulty getting a clean edge with a conventional brush, apply masking tape around the sides of the pane. Paint the horizontal edges first, then the verticals. Next, paint the outer laces of the opening parts of the window. Move on to the fixed parts of the frame -start with the normally-concealed edges and finish with the outer faces and the sill. As a rule, work on horizontal areas first and finish on verticals.

For doors, paint edges and small details such as the beading around panels or glazing first, and finish on the main parts of the frame. As with windows, the general rule is horizontal surfaces first and vertical surfaces to finish.

Cleaning brushes
Brushes used with oil-based paint must be cleaned promptly with white spirit or a proprietary paint brush cleaner. First, squeeze out as much paint as possible. Then work the white spirit or cleaner thoroughly into the bristles – you can’t be too conscientious about this – and squeeze again. Wash out all the cleaner with soap or detergent and water, repeatedly squeezing the brush to try to remove all traces of the paint colour. Finally, wrap the brush in absorbent paper to maintain the shape of the bristles and leave to dry. Looked after like this, you brushes will last for years and will get better with age.

Brushes used with emulsion need only be thoroughly washed out in water, and then wrapped in absorbent paper to maintain their shape.
