Paint to give Bakelite finish?

Post by davegsm82 » Tue May 21, 2013 5:25 pm

I'm busy making a cabinet for a little project, I'd like it to have a nice bakelite finish, similar to a DAC90 if possible, however this will be on sanded down MDF.

Any suggestions?

Dave.

I've never tried it but I seen a description of a method using several different shades of brown paint. Spray on thin coats of the different colours, letting them dry thoroughly between each coat, even spraying the same colour twice, with a different colour between them, and then, using very fine wet & dry (eg 1200 grit) rub away the upper layers in a random fashion. This gives the marbling effect of Bakelite.

Hi Brian,

Thank you for your advice, although I was wondering, what kind of paint should I use?

I'm a complete novice so really, paint could mean anything from Automotive spray to garden gate hammerite!

I have some MDF to experiment on before letting loose on my 'creation' :=D

I hope that whatever paint I use will sort of 'leech' into the MDF, as unfortunately there is some fairly fine detail on my piece and it appears that it is easily damaged, a simple knock can take off a whole chunk.

Dave.

I would try acrylic paint, Dave. There is a huge range of colours to play with. The leaching into the MDF is an advantage because you have then a background colour to work down to. However, I would have thought that if your project is complicated, it will be quite difficult to use wet & dry on it!

Would that be Acrylic Spray paint or something like artists paint?

As for getting the paint into the MDF, i hope it does this to provide a little mechanical strength, I've even considered giving the whole thing a thin coat of watered down PVA glue, however i'm not sure how well the paint would take to this.

I've repaired Bakelite and as Brian has said used Acrylic paints to match the finish. As example here is the classic chip on a Bush DAC90A, just below the dial (see below). I used a combination of browns and terracotta mixes.

I would imagine a similar combination would yield the result you require but on a larger scale.

Good luck look forward to seeing the results.

The spray cans are ideal for large areas but for fine touching-up, that artists' type is good. Till uses the latter to create grain figuring on veneers he has applied in order to match existing bits - see the thread on the wreck of a pre-war HMV 900 set from NVFC here:
