Pine furniture is charming, affordable, and super versatile. But when it comes to the outdoors, pine needs some serious backup. In contrast to hardwoods such as teak and cedar, pine is a softwood that isn’t naturally suited to handle the elements. So if you’re considering placing that lovely pine bench or patio table outside, you’ll want to protect it properly.
You’ll find everything you need to know about staining, painting, or sealing pine for outdoor use in this guide. Our step-by-step instructions will guide you through the entire process of creating long-lasting, weather-resistant outdoor pine furniture.
Step-by-Step:How to Finish Outdoor Pine Furniture
What’s holding you back from getting started? Let’s walk through the process of how to waterproof pine furniture and make it patio-ready.
Before diving into the process, here’s what you should gather:
- Sandpaper (80 to 220 grit)
- Wood cleaner or mild soap
- Exterior wood stain, paint, or clear sealer
- Brushes, rollers, or clean rags
- Drop cloth and painter’s tape
- Safety gear (gloves, mask, goggles)
Step 1: Clean the Surface
A quick wipe-down with a damp cloth might do if the furniture is new. But if it’s been sitting around or previously used, scrub it with a wood cleaner or mild soap and let it dry fully.
This clears away dirt, mildew, and residue essential for getting your finish to stick.
Step 2: Sand It Smooth
You can smooth out the surface with 120-grit sandpaper, following the grain. This helps the finish soak in better and gives you an even, polished look. You should start with 80-grit and work up to 220 if the wood is rough or previously finished.
Make sure you wipe down any dust with a tack cloth before moving on!
Step 3: Apply a Preservative or Primer
If you want long-lasting results, you can consider applying a wood preservative or an exterior primer. You’ll need to stain or paint, depending on what you’re painting.
- For stains or clear sealers, you can choose a preservative that will help prevent mold and mildew.
- For paint, you can use an outdoor primer to help the paint adhere and last longer.
This step adds another layer of pine wood outdoor protection.
Step 4: Apply Your Chosen Finish
Here comes the fun part. We’re now going to add color and protection!
If You’re Staining: The best way to stain exterior wood is to apply an even coat of exterior wood stain with a brush or rag. Put it on and let it soak in before wiping off any excess.
Why it works: The stain penetrates the wood, providing UV protection and allowing the grain to show.
If You’re Painting: After priming, apply at least two coats of high-quality outdoor paint. Use a brush or roller, and let each coat dry completely before adding the next.
Why it works: Paint acts as a shield to protect buildings from moisture and sun damage.
If You’re Sealing: Apply a clear outdoor sealant or spar urethane using a brush. Make sure to coat all surfaces, both top, bottom, legs, and sides. Let it dry completely, then lightly sand and apply a second coat.
Why it works: Water is kept out of wood while sealers preserve the wood’s natural look.
Step 5: Let It Cure
You know, drying and curing are not the same. Your finish might feel dry to the touch in a few hours, but it could take a few days to fully cure. Be sure to follow the product’s instructions. As well as better to avoid exposing the furniture to rain or heavy use until it’s completely cured.
Best Finish Options for Outdoor Pine Furniture
Your choice of finish will depend on the look you’re going for as well as how much maintenance you’re comfortable with. The following are the best for DIY outdoor furniture finishes:
1. Exterior Wood Stain
This is a great way to show off wood grain while adding color and protection. Go for a semi-transparent or solid stain designed specifically for exterior use.
✅ Best for: Protecting you from UV rays and water

Painting gives pine maximum protection and color options. Just make sure you use a primer and paint made for outdoor durability.
✅ Best for: Bold color, long-lasting protection
- Clear Sealer or Spar Urethane
Ideal if you want to maintain the wood’s natural look while guarding against moisture and sun damage. Look for products labeled as outdoor sealant for pine wood or marine-grade for maximum effect.
