    I've followed some of the DIY threads here with great interest and may well undertake a project or 2 when time and £££ permit. Whilst I'm confident in my ability to turn a sheet of MDF into bespoke piece of AV kit (and a small pile of sawdust), how do you regular DIY'ers finish off MDF to give it a presentable finish? I'm thinking specifically about the coloured lacquer type that gives a hard shiny finish and what is the best method of applying it? I don't possess an oil free compressor and/or spraygun kit.

    PS I don't much fancy the veneer option.

    Cheers.

    Mason (Taz) will be able to help you here.

    He'll probably not be on until tomorrow though.

    I take it you mean the wood effect paint. If so I would imagine you will first need to use MDF primer followed by the primer for the wood effect then finally the laquer which must be brush applied to get the grain look.

    I was thinking more like the shiny black or black ash type finish. There is a thread containing a link to a bloke across the pond who made a coffee table subwoofer. He had it finished with a lacquer type finish the like I have never seen available in my circles.

    That effect (AFAIK), can only be reached by spraying a high gloss laquer (several layers of it) over a black paint, Im pretty sure you wont be able to acheive this effect with a brush as the finnish would not be as professional. HSS hire shops will hire you a compressor and a spray gun for quite a minimal charge. Although I wouldn't attempt to spray it yourself unless you have previous spraying experience.

    The more layers of laquer you apply the deeper and shinier the colour will appear.

    prime the mdf (if you are useing a dark colour for the finish. use a dark primer)

    to get that sort off finish use gloss paint watered down with white spirit so that it becomes runny and than you could hire a compressor and a spray gun/ take it to you local car body shop and ask them to do it.

    Cheers.

    With regard to the lacquer, what product is it exactly? and who is likely to retail it.

    I've used the hand held spray cans of 'lacquer' from Halfords before (and a few cans of hair lacquer during my New Romantic phase in the 80's). Can this stuff be bought over the counter in car spares shops and does it need thinners etc etc. I seem to recall that some lacquers can react with the base paint? The problem is that I've heard about it, other people mention it during there DIY projects, but I don't know just what it is I'm actually trying to locate. I hope that makes sense. I don't want to go into a shop and ask for a tin of 'lacquer' to have more questions returned back to me that i may not be able to answer.

    I will most likely go down the spray gun & compressor route.

    Edit: post above landed secionds before this one, hence the answer preceding the question. duh!

    i thnk to get this sort of finish you will require a HVLP compressor and you will need to "cut back" between coats.

    An alternative would be to take it to your local vehicle body refinishers, they will probably be able to do it.......for a price

    2 part epoxy wood filler, Wickes sell it for around £6 for a big tin.
    Easy to mix up and dries in around 20 mins, you can then sand drill etc. Ronseal do an equivalent but its around twice the price
