16 January 2014  |

To Paint MDF Edges and achieve a great result on your boards follow the step by step guide below.


  1. Take some PVA glue and thin by approximately 10% with water. Apply to the edge of your MDF board. Leave to dry, sand with 120 grit sandpaper and repeat as required.

  2. Apply a first layer of undercoat. Be sure to use a spirit based undercoat as water based undercoat will be absorbed by the MDF and cause the board to swell.

  3. Add filler to any gaps or holes if necessary, allow to dry and sand down with 120 grit sanding sponge.

  4. Apply a second layer of spirit based undercoat, allow to dry and sand with 120 grit sandpaper sponge until the edge is smooth.

  5. Apply the first top coat of paint..

Top Tips:

  • The more time you spend on the sanding and filling the better your finished edge will be, it's all in the preparation!
  • To omit the need for applying PVA glue, sanding and filling then try using Paintable Edging Tape which you simply iron on to your edge for a beautiful and smooth finish.
