something to finish mdf

paulfk · 13th March 2009, 07:00 PM

Hi all, sorry if this has been done but a search didn't turn up anything. I am adding another layer to the rear of my horns using mdf and would like to keep the mdf finish. What could I use to seal the mdf without changing the look of it.

It would be nice to see pictures of what you want to modify...

Hi domtw, thats another story, I have started a thread about my horns in the fullrange section, its the Scalford horn. At present I just would like some info on what I can use to seal the mdf. I will post pics when the front baffle has been changed from the rough piece of mdf to something a bit nicer to look at. oh go on then have a look.

Shellac. Use dewaxed, and according to a woodworker mate, it can be painted over later if you choose.

thanks I will look into that

The shellac, which I use on MDF, will darken the MDF quite a bit. But it is a good sealer.

You could also use B-I-N primer (shellac based) color tintable and/or paint them in case you tire of the DIY look.

Clear polyurethane is an excellent sealer.

Hi
your camera has a lot a barrel distorsion, that MDF looks bent
