High quality brushes generally have longer bristles and
a divider inside to provide a larger paint reservoir for
more efficient application of paint, compared with lower
quality economy brushes. The ends of the bristles are flagged
or split at the tips and the brush is tapered with longer
bristles at the centre and shorter bristles to the outside.
This means the paint will go on smoother and more evenly.
Look for a bare wood handle rather than plastic or painted
wood; you'll get a better grip. A rust-resistant metal ferrule
that is nailed on instead of crimped to the handle means
that you'll shed fewer bristles.
Brushes are available with polyester, nylon or natural
bristles. Synthetic bristles are preferred with water-based
paints since natural bristles tend to absorb the water in
water-based products and lose their shape. Some synthetic
brushes are recommended for solvent-based products as well
as for water-based coatings. Natural bristle brushes are
recommended for solvent-based coatings. Brushes should be
pre-primed before use. For painting with water-based products,
prime the brush with water. For solvent-based coatings,
prime the brush with white spirit. All excess should be
removed before dipping the brush into the paint.
Different sized brushes have different functions. Use 30mm
to 50mm brushes for trim; 50m to 80mm for doors, 100mm for
larger areas such as floors and wall sections, and up to
150mm brushes for broad wall areas.Angular sash brushes
are excellent for precise work such as cutting in adjoining
surfaces, eg when tackling window frames.
Quality brushes give you a thicker, more uniform paint
film for better hiding and durability. And a smooth application
will be more resistant to dirt and fungal or algal contamination,
than the same paint with brush marks. To sum up a better
quality finish.
