I've started a DIY speaker project based on some components from PureAudioProjects.

So far, I have fabricated modular speaker baffles from Baltic Birch (they attach to a frame, albeit a bit different from that depicted in the photos below).

I hope to finish the Baltic Birch to replicate, as much as possible, the kind of glossy lacquer like finishes in the attached images.

enter image description here

At this point I have Baltic Birch, un-edged.

I have the constraint of living in a New York apartment. While I have space to work and assemble things, I don't have a place to use spay equipment.

I'll need to apply primer and finishes by hand.

How do I get as close to the desired finish as possible? If I sand the plywoods edges, can I get away without edging the baffles?

Any suggestions on sanding process (edges and faces) appreciated. This post, Will painting the edges of plywood hide the layers?, probably answers the edge question, but I'd think Baltic Birch makes a more forgiving edge then typical plywood.

I generally understand the process of priming, sanding, and painting; but specific recommendations for what:

  • grit of sand paper to use at what stage of the process as well as
  • specific primers and paint and application suggestions

much appreciated.

Perhaps a satin finish would prove more forgiving, so I'll happily consider that. Again, any guidance welcome.


Your question has been identified as a possible duplicate of another question. If the answers there do not address your problem, please edit to explain in detail the parts of your question that are unique.

I have a number of constraints affecting the materials with which I have to work and where I have to work (all discussed in the original post) that the suggested answer does not address. I hope to get answers or guidance that help me achieve a result as close as possible to the desired result (see images) with what and where I have to work.

That said, the suggested "possible duplicate" certainly helps (and is really interesting!), it just doesn't fully answer the problem.

  • I was posting an Answer but I realised this has been amply covered in previous Answers. Fair warning, the finish you're going for will be extremely challenging to produce on plywood and especially working by hand. As I say a couple of other previous Q&As may be of further help, primarily this one, How do I achieve a “piano black” high gloss finish on wood?

  • I will answer this later when I have a computer that displays the image. I have built about 3 sets in the last 6 months so I will be able to help I think. If you need a good website for stuff here is a website below. Also GRS speakers if you are on a budget. They are great. parts-express.com

  • Combining the information in the two previous Questions already linked to just about covers everything you need to know about prepping the wood for paint and then subsequently priming and painting it if you want to paint it manually. The only part that then remains is finding primers & paints that are suitable and available to you locally. But instead of doing this manually it may be worth going with spraycans, although they tend to be an expensive way to paint it might actually work out more cheaply in the end for this project because you won't need to buy any brushes or rollers or solvent.

  • @Graphus -- Any suggestions on what kind of spray can pain I could use? I would likely have to spray outdoor on a fire escape or on the roof of my building, but maybe that could work. Some concerns about dust.
