Prepping Your Surface for Painting
The key to refinishing furniture is prepping. Follow these steps for furniture prepping before using MudPaint:
At the very least, a light sanding is always recommended. You may decide to use an electric mouse sander, an orbital sander or a non-electric sander. The upside of electric sanders is that you can accomplish a lot of sanding very quickly. The downside of electric sanders is that you may take off more material than you wanted. We would recommend using an electric sander on large surfaces that need a lot of sanding. A handheld non-electric sander is great for smaller surfaces that just need a light sanding.
What Grits of Sandpaper Should I Use?
We recommend using 180-220 grit on the surface of the piece. Then, 320 grit after the first coat of primer (if you are using a primer) or after the first coat of paint. For sanding the last coat, we recommend 320-400 grit sandpaper or even 600 if you like a really smooth surface.
How Much Sanding is Needed?
A surface that has been waxed, treated with furniture polish or just has a slick surface that paint won’t adhere to should be well sanded. It’s not necessary to sand the surface down to the wood, but to sand it to a point that the paint has something to adhere too. If you can’t get your surface sanded to a point that paint will adhere or just don’t want to do the extra work, consider using a coat of primer.
To Prime or Not to Prime
Our recommended brands of primer are water based primers, we’ve also had success using Cover Stain & Rustoleum’s All Purpose Primer. We do not recommend BIN’s shellac primer with MudPaint. To save time, consider using the primer in a spray can. Spray from about 12″ away from the surface and do not overlap your strokes too much, in order to prevent dripping. Primer drips should be allowed to dry and then sanded smooth. We recommend a light sanding over a coat of primer to maintain a smooth surface to paint on.
Paint will not normally adhere well to laminate surfaces without a coat of primer underneath. You can try a test area to see if MudPaint will adhere to your laminate surface. If it does not, we would recommend applying a primer before painting.
For plastic surfaces, always use a coat of plastic primer before applying MudPaint. MudPaint will not adhere directly to plastic. Most paints will not adhere to plastic without a primer designed to adhere to plastic surfaces.
Once your surface has been sanded and paint can adhere to the surface, you will need to make sure the surface is completely clean. We recommend a wet rag, wrung out. Or windex and a rag. The idea is to make sure there are no oils, dust or residue left on the surface. No paint or primer will adhere well to oils, wax or dust. Do a complete and thorough cleaning.0
