At A.G. Williams Painting Company, we’ve been painting with pride and passion for over 100 years, serving homeowners across New York and Connecticut. One of the most frequent questions we hear from our clients is: “What’s the best way to stain exterior siding or wood surfaces?”
The truth is, exterior staining can be tricky. Wood is a natural material, which means it absorbs stain differently depending on its age, condition, and exposure to the elements. Proper preparation and technique are just as important as the stain itself.
To help, we teamed up with our Benjamin Moore representative to put together a list of professional exterior staining tips that will help you get durable, beautiful results, whether you’re tackling the project yourself or considering hiring a professional.
Why Maintenance Matters
Wood siding and outdoor surfaces are constantly exposed to sun, rain, wind, snow, and humidity. Over time, this exposure can cause:
- Fading and discoloration from UV rays
- Moisture damage that leads to rot or warping
- Mold, mildew, and algae growth
- Splintering or cracking
Staining not only enhances the natural grain and beauty of the wood, but also provides a layer of protection against the elements. Unlike paint, which forms a film on top of the wood, stain penetrates deep into the surface, allowing the wood to “breathe” while shielding it from damage.
When done right, a good stain can extend the life of your siding and improve your home’s curb appeal dramatically. Here’s a blog with more detailed tips for exterior maintenance painting.
Pro Exterior Staining Tips for Success
Here are the top 10 tips from A.G. Williams Painting Company and Benjamin Moore for a flawless exterior stain finish:
1.) Keep the Stain Mixed
Unlike paint, stain separates easily. Stir it regularly while applying to ensure an even color across the entire surface.
2.) Rough Surfaces Absorb More Color
Rough-sawn siding or weathered wood will drink in more stain, producing a darker look than smoother boards. Always account for this when estimating color intensity.
3. Avoid Direct Sunlight
Hot surfaces cause stain to dry too quickly, leaving lap marks and uneven penetration. Choose a shaded area or work in the cooler hours of the day.
4. Work From the Top Down
Start staining at the top of your siding and move downward to prevent drips from ruining finished areas. Gravity works in your favor here.
5. Always Follow the Grain
Brush or roll stain in the same direction as the wood grain. This helps it soak in evenly and enhances the natural look of the wood.
6. Test Before You Commit
Stains can look very different once they’re applied to real wood. Test a small, hidden area to make sure the color is what you want.
7. Be Careful With Pressure Washing
If you’re prepping with a pressure washer, angle the spray along the grain of the wood to avoid splintering or gouging the surface.
8. Use Prep Products the Right Way
Wood brighteners, cleaners, and conditioners are concentrated. Apply them with a pump sprayer, garden hose applicator, or pressure washer, never stronger than the manufacturer recommends.
9. Don’t Assume Stronger is Better
Mixing prep solutions too strong doesn’t speed up the process. In fact, it can damage the wood and make neutralization harder.
10. Finish Staining Soon After Prep
Try to stain within one week of preparation. Otherwise, dirt, pollen, and mildew can start settling back on the surface, affecting adhesion.
Choosing the Right Stain
One of the biggest decisions homeowners face is whether to use a solid, semi-transparent, or clear stain. Each has pros and cons:
- Clear Stains: Highlight the natural wood grain but provide the least UV protection. Best for newer wood in shaded areas.
- Semi-Transparent Stains: Allow some grain to show while offering solid weather protection. Great for most siding and decks.
- Solid Stains: Provide the most coverage and longest durability, but hide the natural grain. Best for older or weathered wood.
At A.G. Williams Painting Company, we often recommend Benjamin Moore ARBORCOAT® exterior stains because of their durability, color range, and proven performance in the Northeast climate.
Common Exterior Staining Mistakes to Avoid
Even with good intentions, many DIY staining projects fall short because of preventable mistakes. Here are some pitfalls to watch out for:
- Skipping prep work: Stain won’t adhere properly if the wood isn’t clean and dry. Over-applying stain: Too much product can leave sticky, uneven patches.
- Ignoring weather conditions: Rain within 24–48 hours can washA thin, translucent layer of paint or color applied to a surface, often to add... More away fresh stain.
- Using the wrong applicator: Brushes are best for precision; sprayers and rollers work well on large surfaces but need back-brushing.
- Not maintaining regularly: Stain needs periodic refreshing to stay protective.
Seasonal Staining Tips
Timing matters when staining exterior siding. Here’s what to consider season by season:
- Spring: A great time to stain after winter damage. Just ensure surfaces are dry and free of early pollen.
- Summer: Work in the mornings or evenings to avoid hot midday sun. Humidity can slow drying.
- Fall: Ideal conditions, cool, dry weather helps stain cure evenly before winter sets in.
- Winter: Not recommended unless temperatures are consistently above 50°F and the wood is dry.
Maintaining Your Stained Siding
Staining isn’t a one-and-done project, it requires upkeep. To extend the life of your stain:
- WashA thin, translucent layer of paint or color applied to a surface, often to add... More siding annually with a mild cleaner to remove dirt and mildew.
- Touch up faded or worn areas as soon as you notice them.
- Reapply stain every 3–5 years for semi-transparent products, or every 5–7 years for solid stains.
For decks, fences, or high-exposure areas, you may need more frequent touch-ups.
