Has anyone got any experience of veneering? I've got this far -  I need to sand a couple of bits but it dulls the veneer and makes it muddy and undefined. Will it come back to life when its coated with Rustins Plastic coating or do I need to do something after sanding it? cheers |

Cheers for the link. I've read its advised to make sure the grain is flat and its nice and smooth or something. Guess once theres a high shine on it all the defects will show through. I've also got a couple of little glue spots I need to get rid of.
Its quite a long process with flattening the burr walnut etc but should be worth it in the end. Just hope it doesn't delaminate a year down the line.

you need to be careful sanding veneer. if you don't remove the finish off it completely you may end up with a blotchy finish due to the difference if the new finish soaks into the veneer as it is porous, or doesnt in the case of old finish or glue. I understand that if you wipe over the surface of the veneer with methylated spirits it will give an indication of the patina and grain finish you will end up with, but wont raise the grain like water would. when I redid my heralds dashboard, I used a new plywood base and got veneer off a roll (from ebay) and used an iron on film glue (also from ebay) to me it seemed the best option, I could have used pva glue, but the water in it would have caused the veneer to ripple and would have been harder to get a flat surface. I used sanding sealer to seal the surface of the veneer, then sprayed it with car lacquer. as I wanted a satin finish, I then flatted it back with 0000 grade steel wool. you can just about see the finish in this picture    |

Cheers for the advice. Its new veneer on there so haven't got to worry about old varnish etc. I've been told twice now about the meths trick so i'm going to try some sanding techniques on a bit of scrap and get the meths out. On advice from online i'm going for Rustins Plastic Coating for the top coat with a nice thick gloss finish so it looks like the original.

Try not to sand the veneer but use a scraper instead( sharp stanley blade at 90 degrees) this would be the prefered tool of a cabinet maker and will not change the surface of your veneer . Rustins is a good product use this only, not with any other product , build the layers up and allow to dry between. Sand with 1000 grade whan you have enough depth and polish and you will acheive a mirror finish. Open the windows though it does smell dreadfull.

Hi, its all sanded now and looks good for it, although the brightness has been taken out of the veneer its now silky smooth and I think once the rustins is on the definition wlll come back. Its not a hard job if anyone else is considering it, all I would say is use plently enough glue when adhering the veneer to the backing. I wish i'd have used a little more as in a couple of places around the edge there are a couple of very small pockets where the surfaces arent joined. I'm going to try and glue them with a syringe and needle.
I also found that a mix of meths, Glycerine and water worked great for flattening the waves from the veneer before glueing.
