cragman 2,791 Posted September 11, 2017 Report Share Posted September 11, 2017 What's the best first coat of paint to put on MDF? I've had an MDF cupboard built in a bedroom and I want to paint it. What has anyone found to be the best for sealing? I intend to finish it with satinwood, thanks Quote Link to post Share on other sites
jok 3,368 Posted September 11, 2017 Report Share Posted September 11, 2017 You've heard the advertisement. 'Ronseal' it does what it says on the tin. Jok. Quote Link to post Share on other sites
stealthy1 3,964 Posted September 11, 2017 Report Share Posted September 11, 2017 I'd just use two coats of 50/50 water and paint of your choice, and two full coats (with out the water). 1 Quote Link to post Share on other sites

toby63 1,236 Posted September 23, 2017 Report Share Posted September 23, 2017 a good couple of coats with a good primer and sand with a fine grit something like a 400 grit between coats Quote Link to post Share on other sites
Chid 6,621 Posted September 23, 2017 Report Share Posted September 23, 2017 I'd just use two coats of 50/50 water and paint of your choice, and two full coats (with out the water). Water causes mdf to swell , it ain't a good idea to paint mdf with a water based paint let alone a paint mixed 50/50 with water Quote Link to post Share on other sites
Chaff 3,622 Posted September 23, 2017 Report Share Posted September 23, 2017 Oil based primer undercoat 2 coats then top coat with satin wood oil based again. You can normally tell the water based paint from oil based by how it says clean brushes As in if it says clean brush with water then its water based. Quote Link to post Share on other sites
