How to Paint on Stainless Steel

posted Jan 30, 2012, 9:21 AM by Dustin Romero

In case you have seen it yet, here is the new paint job on the cart. It's a chalkboard paint (black), with the logo painted over it. Stainless steel is really tough to get paint to stick to, but with the help of the Glidden professionals we got it done right. Here's how.

  1. Cleaning: We cleaned the surface with a lacquer thinner we got at the paint store. We then used soapy water to wipe off the residue, then rinsed lightly with warm water.
  2. Preping: We then did a wet sand with a 50 grit sandpaper over the whole cart. This roughage helps the paint stick. We then cleaned it again with warm water to get all the dust off.
  3. Primer: This is where it gets particular, for details you'll want to go to a professional paint supplier. We went to the local Glidden distributor. The professional there will help you get the right primer for the job. Basically it's this. We used a two part epoxy primer. An epoxy means that it has two chemicals that when combined make a super hard element thing. In other words The gallon of primer came with a little jug of stuff you poor into and mix, that activates it, then when it dries it's super hard. It's important to use a two part epoxy when when working with stainless steel, because a standard primer will not stick to the surface.
  4. Setting: There are specific times that the manufacturer suggests you let the primer set, they are temperature dependent, the expert guy will explain it to you.
  5. Painting: After the primer set we painted over it with some black chalkboard paint we bought at Wal-Mart. We did two coats over two days. After it dried sufficiently we used a stencil that we printed on my moms laser cutter to paint the white logo on. Let dry and blammo! New cool looking front panel.
