Synthetic paint-brush sizes

Choose a brush width around the area you need to cover and the edges you need to reach. A narrow angled brush and a broad flat brush offer different access, even when their bristles are made from the same material. Harris identifies bristle material, size, shape and surface texture as separate buying considerations. Check the brush’s stated paint type as well: a general synthetic description does not replace the exact manufacturer’s recommendation for a particular coating or finish.

MATCH THE DETAILS TO YOUR JOB

What to check before buying

  1. Compare the stated brush width in millimetres or inches with the trim, panel or edge being painted.
  2. Check the manufacturer’s paint compatibility, including whether it is intended for emulsion, gloss, stain or varnish.
  3. Choose the brush shape and handle length around access to corners, narrow edges and awkward recesses.
  4. Read the pack contents by individual width, and check whether pictured protective sleeves are included.
