With all the chalk painting and waxing rage I thought this may be a helpful post for all of you furniture painters who would like to repaint your chalk painted or waxed surfaces.
First step is determine if your chalk painted surface has been waxed. I usually scratch the surface using a putty knife or a fingernail on several different areas on the piece to see if wax comes off on my putty knife or under my fingernail.
No Wax –
If you get no indication of wax on the surface you are ready to clean with TSP or Degreaser, scuff sand, wipe off your saw dust with a damp rag and start painting. I recommend Fusion TSP because it is a great non-toxic version of the store bought TSP that needs to be applied with gloves and rinsed off after.
Note: Applying paint over chalk paint may require a little more sanding to achieve a smooth surface. Chalk paint is very textured. Just remember that any texture or flaws may show through your newly painted surface so you’ll want to sand accordingly.
Removing wax from a surface may seem daunting but with the right tools it’s relatively easy.
Here’s what you’ll need:
1)Pour a generous amount of Odorless Solvent or Mineral Spirits on your surface or pour onto the scrubby side of your sponge.
2)Take the scrubby side of your sponge and scrub the surface of your piece. You should start seeing smalls amounts of wax ball up on the surface of your piece or on your sponge. The amount is really depending on how much wax was originally applied.
3)After you’ve scrubbed the entire piece, let it dry. After it’s dry use Fusion TSP or a Degreaser to wipe down the entire piece.
After your piece has dried make sure to test the surface to make sure all wax has been removed. I take a fingernail and scratch several different areas of the surface to make sure I’m no longer removing wax. If you find areas that still seem waxy follow steps 1-3 again on those areas.
If all wax has been removed the next step is to scuff sand the surface to smooth out any flaws or textures that you do not want showing through your final painted finish. Make sure to wipe the entire piece down with a damp rag to remove sanding residue.
Now you are ready to paint!
