Painting MDF Pannelling

WildCardDoW

So have some MDF Pannelling that is raw / untreated.

What's the best way to prepare it for painting and what paints can be used?

Is it sealant, primer and then paint of choice? Any restrictions on the paint used, like does it have to be Satinwood?

I can't seem to find primer in specific colours (only white) so do I need to get it made up in a matching colour?

is it cheap b and q level rubbish mdf or standard decent mdf, or MR mdf or hydrofugo.
depending on the above you will need to give the edges coats of sealer. 1 will do hydrofugo but you could want 4-5 on cheap crap.
i like BIN primer for the edges. it dries really fast and sets the fibers before they raise up. 4put on a good coat of BIN on the edges and sand between them
then 123 everything,
sand everything
undercoat and top etc as normal

MDF was from woodworkers.

I'm more curious about finishing paints that can be used on it and if I should use coloured primers than sealing it. Sorry. 😂

mdf should be decent then.

top coaats is more personal preference . coulored primers are great for darker colours or more translucant paints. i generlly dont unless needed because the rest of the can isnt as usfull down the line

Thanks, might just bring in a proper painter for the panelling and I'll do the walls. Want it done right haha.

I'll see about it primer wise, it's a dark enough colour I'm planning on using so I figured I'd run the risk of needing to use more of it as a result of using a white primer.

You'll need to use more of it if you don't use the primer.


Sand the bollix out of it. Use BIN on it. Light sand to smooth then use whatever you want on it. I find emulsions work perfectly when done in light layers. Very light sand between.

This is what I use as Primer. Works well and much cheaper than BIN.

For the edges I put a coat or 2 on first before sanding. Comes out really well and no issues.

Ha I knew I'd need a primer regardless - just enquiring about the general thoughts on it. Just off the. Shelf in white or go to the effort of getting one made up that is more in line with the colour!
