Pistol p Posted October 10, 2018 Report Share Posted October 10, 2018 Ive been asked to paint some sheets of MDF for a customer. I don't want to spray it but was considering using a roller. Any hint and tips with regards to materials and techniques please? Quote Link to comment Share on other sites More sharing options...
winnie&bezza Posted October 10, 2018 Report Share Posted October 10, 2018 Seal edges with an edge primer or watered down wood glue and sand between coats with 180g paper to get a good edge. Or you can fill and sand edges with two part filler. Roller on primer/undercoat and again sand with 180g paper. I’d use 240g between top coats. Depends if they want a brush finish. I would use moisture resistant MDF (green one) as it paints better. Quote Link to comment Share on other sites More sharing options...

buze Posted October 11, 2018 Report Share Posted October 11, 2018 I use PVA to seal everywhere, helps a lot, especially for the first coat. Alternative to painting is to vinyl it, I did that on a couple of pieces (especially if the edges aren't visible) and it looks pretty good too.

Scully Posted October 11, 2018 Report Share Posted October 11, 2018 I just paint with Johnstones acrylic wood primer, sand, then another coat, sand, then top coat. Quote Link to comment Share on other sites More sharing options...
