How to Paint Over a Varnished Surface
- 1). Sand the wood with 220-grit sandpaper. This sandpaper isn't so rough that it will cause the wood to splinter, but it will remove the gloss.
- 2). Wipe down the surface using a trisodium phosphate cleanser. The TSP will get rid of any oily residue that lingers on the wood.
- 3). Dry the wood with a clean towel.
- 4). Prime the wood with a stain-blocking primer. Some woods release natural oils that can bleed through regular primers. A stain-blocking primer ensures that you get good paint coverage.
- 5). Paint the wood using any latex or oil-based paint. A roller makes short work of large objects, whereas a paintbrush is your best bet for smaller, intricate items. Wait for the base coat to dry, and then apply additional coats as needed. Avoid using the freshly painted item for at least 24 hours.
