CNC Router and Engraving Has anybody got any good tips on finishing the edge of MDF? Posted by hippo on October 6, 2007 at 3:57 pm Has anybody got any good tips on finishing the edge of MDF. It seems to take forever to get a reasonable finish, there must be an easier way. Cheers, Simon.

Angelique Muller Member October 6, 2007 at 7:20 pm there is a special sealer for it….but i think a few coats shellac might work aswell….. Ian Johnston Member October 6, 2007 at 11:28 pm normal wood glue rubbed into the porous end, wait to it dries and give it a good sanding, works every time, Ian Andy Gorman Member October 6, 2007 at 11:34 pm If you water down some pva (wood glue) you can just brush it all over to seal.
