Applying piano black finish help

[Toast_Master]

Hey

My box construction is nearing an end and have to start planning on box finish, I have chosen, I want a piano black finish

I have googled on it and looked every where, I have found little info but not enough to satify my hunger and need.

Could some one pls, explain step by step or lead to a page explaing my exact situation

..My box is pure 25mm mdf board,----what now, I have a faint idea but would like to be told the correct way

Thanks

Heres a pic of my subwoofer insides

An externally hosted image should be here but it was not working when we last tested it.

hope you like sanding...



Sand, fill, sand, fill, sand, sand, prime, sand, prime, sand, prime, sand, sand, sand, paint, sand, paint, sand, paint, ad nauseum...

The process is so involved, but with few different steps, I did it on a box of mine, but after the effort would NEVER do it again.

Get a auto paint shop to do it is my suggestion. (unless you have a nice paint booth and patience)

Are you serious...can I do that...will they do all the required stuff

 

[just a guy]

If you pay them they will do whatever you want. But just remember, it's going to be expensive - better get Maaco - lol.

This is not THAT hard. Do you have spray equipment?

😀

 

[Toast_Master]

I dont personally have all that equipment, but the college I go to does, and I have access to it, other than going to the auto, shop I would like steps on how to do it

thanks

 

[poobah]

oops... Do you want shiny black or satin?

😀

 

[Toast_Master]

shiny black....thats gloss black aint it?

 

[poobah]

yup

You might cheaper to go to an autobody shop.

You need a quart of this, this, that, and that, quart prices suck.

Have you sprayed before? If not, is it in your life-master-plan?

😉

 

[Toast_Master]

lol, well its not in my life master plan but I am going to make many more subwoofer and speakers over time, cause as we all know, there always room for improvement and its so dam addictive

 

[poobah]

Well... you need to **** or get off the pot.

Here's the deal; wood (yes... mdf) is an unstable material. It shrinks and swells when solvents are applied. The old-school-labor-intensive ways of shiny black wood are just that... labor intensive.

If you can spend more on exotic primers... you can do things faster.

I can tell you more... but I hate typing.

If you can use a catalized urethane/or epoxy primer with high solids... then you are on your way. Then you can follow with laquer with minimal effort.

Painting wood for gloss is like painting a tee-shirt. Metal is much easier it doesn't shrink or swell

Perhaps the "happy point" would be to do the primer and prep yourself, and let a pro squirt the laquer (or urethane).

 

[Toast_Master]

I see, so if I dont skimp on the primer, it should be an easy enough job? or easier

 

[poobah]

Yep,

You need a 2 part filler/primer... urethane or epoxy.

There is also a water-based system called "piano-laq"... paint brush stuff.

Search for it here. it was in a recent thread

😉

 

[Toast_Master]

Ok I searched but says it dosent exist, you seem to know what your on about...could you tell me the steps poobah

 

[poobah]

let's find "piano laq" first.

Start a new thread, "need piano-laq" the guy is a regular poster.

If this is your first attempt... I think this stuff could really help you.

 

[poobah]

OH... night-night

I'll be around...
