Identify the surface and follow the current instructions for your exact products. Do not sand or strip uncertain old coatings. Read the safety guide before disturbing materials.
Choose a brush you can control
A good synthetic brush is a common choice for water based paints. Check the coating maker’s recommendation for other systems. A medium width brush that feels comfortable is easier to control than the largest brush on the rack.
Load part of the bristle length, not the ferrule. Tap off excess against your container rather than scraping nearly all the paint away. Start on a practice board to understand how the paint leaves the brush.
Match the sleeve to the surface
Shorter pile generally leaves a finer texture on a smooth surface; longer pile reaches into a rough surface but holds more paint and can leave more texture. Sleeve material matters too. Use the paint maker’s specified sleeve and pile as your starting point.
Condition a new sleeve as its maker recommends and remove loose fibres. A mini roller helps on small flat panels, but a foam sleeve is not automatically right for every trim coating. Do a sample first.
The unglamorous kit earns its keep
A secure dust sheet, clean bucket, filling knife, sanding block and good light will be useful long after a novelty gadget has gone in the drawer. Use a stable platform when needed and an extension pole where practical. Never balance a chair on another object.
Choose masking tape for the surface and the time it will remain in place. Test delicate finishes first, and remove tape within the tape and paint makers’ guidance.
Common mistakes
- Using a worn sleeve that sheds fibres.
- Buying a rough surface roller for a smooth door.
- Treating a dust sheet as protection against every liquid spill.
Do not improvise access for stairwells, high ceilings or exterior work. Arrange equipment and competent help suited to the job.
