Solid Stain vs Paint for Exterior Wood

Solid stain vs paint is a common question for siding, trim and decks, and the honest answer is that each wins in a different place. Fine Homebuilding lays out the core differences, and This Old House adds how long each type of stain tends to last. Here is how to choose for your house.

What Is the Difference Between Solid Stain and Paint?

Paint forms an opaque film on the surface. Fine Homebuilding says that film is 0.002 to 0.003 inches thick once dry, fills wood pores more effectively than stain and obscures the grain. Solid-color stain, in the words of This Old House, resembles flat paint and hides the wood's grain but not its texture, because stain penetrates the wood instead of sitting on top of it.

Which Lasts Longer, Paint or Solid Stain?

Paint, usually. Fine Homebuilding says paint may endure several times longer than stain before it needs recoating, while solid stain will have to be recoated more often, in as little as two or three years on exposed areas. This Old House gives a wider range by type: semitransparent stain typically needs reapplication every two to three years, and solid-color stain every five to seven years. Sun, water exposure and how horizontal the surface is all push those numbers around.

Which Is More Likely to Peel?

Paint. Fine Homebuilding notes the paint film can peel, while stain will not peel like paint because it does not form a film. That is also why recoating is easier for stain: This Old House quotes a painting contractor saying the prep work for recoating stain is far easier and faster than for paint. When paint fails, the old film has to be scraped or sanded back before repainting. If your house was built before 1978, scraping old paint falls under the EPA lead-safe rule for paid contractors, and a repaint takes planning around weather.

How Do They Look Different?

Paint gives a uniform, opaque finish that hides the wood. Solid stain looks like flat paint but lets some wood texture show through. Semitransparent stain changes the color without hiding grain, per This Old House. If you want the wood to read as wood, a semitransparent product is the closer match, and if you want a crisp painted look, paint is the stronger choice.

Which Costs More?

Fine Homebuilding says paint costs roughly 25 percent more than a stain of comparable quality, and that most paint should go over a primer, which adds a step. Stain needs no primer. Over time the picture changes, because stain is recoated more often and a good paint job is recoated less often, so the cheaper product per gallon is not always the cheaper choice per year.

Siding or Deck: Which Should You Use?

On vertical siding and trim, paint's longer life is often the better value, since those surfaces are expensive to scaffold and prep again. On horizontal surfaces such as a deck, which take the most sun, water and foot traffic, many homeowners choose stain because it does not peel and recoating is simpler. This Old House lists decks, siding, fences, doors, trim and composite decking among the surfaces suited to stain. If the wood itself is soft or rotted, finish is not the fix: that is a repair or a replacement, which is where our siding and deck work comes in. For exterior painting, see our painting services.

The Bottom Line

Paint lasts longer and hides more but can peel, while solid stain is simpler to recoat and does not peel, though it may need redoing in two to seven years depending on type and exposure. Use paint where you want a durable, uniform finish on siding and trim, and stain where recoating ease matters, such as decks. Get a Free Exterior Estimate
