Topic tags/keywords: question jointer spray gun finishing refurbishing

How do you do it?
The rust on my jointer is all wire brushed off, and i masked off all the machined surfaces.
The paint is in decent condition for painting over, so no need to strip it.

My question is, how many coats? and what do i do after the paint? lacquer, poly,nothing?
Also, i dont have a sprayer, so is spraying from the can ok?

Thank you all so much for helping me through this restoration! I am eternally grateful.

Wipe down with dilute phosphoric acid solution, followed by mineral spirits. Then brush on at least two coats of a good quality oil based enamel.

I did not understand most of that,
what i did understand, I dont have

I have a can of black spray paint + primer (2 in 1), also, i have turpentine

is phosphoric acid for cleaning? is it absolutely necessary? if so, its only $12 at home depot

You plan on painting the whole jointer with one can of black spray paint?!?

Phosphoric acid will remove any remaining hidden bits of rust and prep the surface for good adhesion. You can get a gallon of the stuff pretty cheap at the BORG as you mentioned. Dilute 50/50 with distilled water, wipe it on, wait a minute or two, then wipe off. I then like to wipe everything down with mineral spirits just to remove any residual contaminates. Preparation is 99% of painting. And no, it’s not absolutely necessary – but you may wind up with a less than ideal paint situation down the road… like peeling paint, or paint that easily chips off when hit.

I also like to brush on the enamel, as it provides a thicker, more durable surface. Primer is not necessary.

Cheers,
Brad

Thank you so much, that was the perfect explanation!
Ill head to home depot tomorrow, also, i plan on color matching the jointer and cabinet so i can get as close to the DELTA color as possible.

The black is only for the back of the fence area, and the very bottom of the cabinet.
Can i just spray the paint out in a separate container and then brush it on?

also, what the heck is a BORG?

Big Orange Retail Giant. 8D I’d recommend buying even a pint of oil based enamel instead of draining a spray can. You’ll get more paint that way. If you want to spray, use the Rustoleum “professional grade”, or whatever it’s called. It works really well. It comes in a bigger can, 14 or 16 oz instead of 12 oz.

I’ve been using Rustoleum for a few machine projects, a lathe, a drill press, and a tool box.
Primer first, then several more of the color you choose. I live in a dry climate, and rust coming through hasn’t been an issue fo me. Rustoleum offers several shades of grey.
