The simplest way to create a weathered finish on painted wood is to break a few of the rules. The standard instructions for wood refinishing are designed to produce a smooth finish that will make the wood look like new. By selectively violating those guidelines you can, instead, raise the wood's grain to give it a subtle, weather-worn texture that evokes the appearance of driftwood. The key is to expose wood to water during the stripping phase of your project.
1. Off With The Old
1 Apply NMP paint stripper paste to the wood's surface using a disposable paint brush, and leave on for at least 3 hours. If there are several layers of paint and primer, the paste should be left on the wood overnight.
2. Off With The Old
2 Scrape off the paint stripping paste using a carbide blade paint scraper. Start by scraping in the direction of the grain, then remove any residue by scraping perpendicular to the grain. This may create small scratches or nicks in the wood.
3. Off With The Old
3 Rinse off any leftover paint and stripping paste using a hand-trigger spray bottle to thoroughly wet down the wood. Wipe off the excess moisture using a cotton cloth.
4. Off With The Old
4 Soak a fresh cotton rag with denatured alcohol. Wipe down the wood and allow the alcohol to thoroughly penetrate the surface. Refresh the rag with alcohol as needed.
5. Off With The Old
5 Spray the wood with water again, then wipe off any excess moisture with a cotton rag and allow the wood to dry completely.
6. Off With The Old
6 Sand the wood, rubbing 180-grit sandpaper in the direction of the grain to smooth down any rough surfaces.
7. On With The Not-So-New
1 Dilute an all-purpose water-based white paint primer with water, using a ratio of 3 parts water to 1 part primer.
8. On With The Not-So-New
2 Brush the primer mix in the direction of the grain onto a roughly 2-foot-square section of the wood. Using a clean cotton rag, rub the primer into the wood and wipe off any excess. Repeat until the entire surface of the wood has been treated.
9. On With The Not-So-New
3 Wait 2 hours for the surface to dry.
10. On With The Not-So-New
4 Sand the wood gently with 180-grit sandpaper to smooth off any roughness. Wipe off any sanding residue using a tack cloth.
11. On With The Not-So-New
5 Apply a thin coat of flat-sheen water-based varnish using a lint-free cotton rag. After 3 hours, apply a second coat.
Items you will need
- N-methyl pyrrolidone (NMP) paint stripping paste
- Rubber gloves
- Safety glasses
- Disposable paint brush
- Carbide-blade paint scraper
- Hand-trigger spray bottle
- Clean, lint-free cotton rags
- Denatured alcohol
- 180-grit sandpaper
- Water-based paint primer
- Tack cloth
- Water-based varnish
- NMP strippers can remove up to 7 layers of paint and primer in a single application. When multiple coats of paint and primer are present, it will take longer for the stripper solution to work. Read the instructions on the stripper's label for suggested working times.
- NMP strippers are often marketed as environmental strippers, and many products labeled as soy-based strippers list NMP as one of their primary ingredients.
- On softer woods, the diluted primer may appear blotchy after application, and this can enhance the weathered effect. If you prefer a more even appearance, apply a wood conditioner before applying the primer mix.
- Slip on a set of rubber gloves and protective eye wear before coming into contact with chemicals throughout this project.
- Unless you are confident that all of the original paint was applied after 1978, perform a lead paint test before disturbing the painted surface. Lead paint test kits are available whereever paint is sold, and professional testing services are available in most larger communities.
