What to Consider When Choosing the Best Exterior Wood Stain
Before you start shopping for the best exterior wood stain, there are a few factors to consider, including your intended use and the transparency of the stain. The following section breaks down the most important points to keep in mind while hunting for the best exterior wood stain.
How you intend to use your stain will have a lot to do with choosing the best exterior wood stain. For one, any outdoor wood surface, whether it be a fence, chair, deck, or siding, requires an exterior-grade stain. These stains help preserve the wood in rougher environments, whereas interior-grade stain won’t provide the same protection.
Also, some stains are better for use on decks than others. Since decks lay flat, they’re more susceptible to standing water and the sun’s baking UV rays than other wood surfaces around your property. The foot traffic is also a concern. For these applications, a penetrating stain is often the best bet.
Outdoor furniture frequently uses wood with attractive grain patterns. For this reason, a transparent stain would protect the wood without blocking out the grain.
Exterior wood stains come in a few varieties: water-based or acrylic, oil-based, and a hybrid stain. These names refer to the liquid that the manufacturer uses to mix the pigments and protective particles.
Water-based or acrylic stains use water as the base liquid. These stains are relatively easy to apply, and they clean up with a bit of soap and water. They’re also less likely to cause any respiratory issues as they typically have a low-VOC (volatile organic compound) content. The downside is that they don’t penetrate wood quite as deeply as oil-based stains, so they might not last as long.
Oil-based stains really penetrate the wood, which makes them longer lasting. Once they soak into the wood grain, they protect from within and strengthen the bonds of the wood fibers (this is also true for some penetrating water-based stains). Oil-based stains also really showcase the wood grain. Cleanup can be a hassle, however, as it usually requires mineral spirits. Also, keep in mind that oil-based stains can be very irritating to the respiratory system, so wear a respirator mask.
Film-Forming vs. Penetrating Stain
Various products will protect wood surfaces in different ways. For instance, some products penetrate the wood grain and protect it from the sun’s UV rays and moisture from within. Other products create a protective barrier, or film, that encapsulates the wood to protect it. There are pros and cons to each.
Penetrating stains seep into the pores of the wood, strengthening the bonds in the material and protecting it from within. They’re long-lasting and durable, and they can highlight the grain. However, they don’t do a great job of hiding unsightly blemished or mismatched grain—even if they’re solid.
Film-forming products encapsulate the wood and protect it like a shell. They do a better job of hiding irregularities between wood planks and less attractive areas. However, their bond to the wood breaks down over time, requiring more frequent reapplication. This depends on factors like hours in the sun each day, foot traffic, and the condition of the deck boards.
Not only do the best exterior wood stains come in a variety of colors, with varying degrees of penetration, but they also come in different transparencies. This is an important consideration to keep in mind.
- Transparent stains are entirely see-through, and they rarely change the color of the wood below it by more than a shade or two. They don’t hide any of the wood grain, and they’re excellent for expensive exotic exterior woods, though they work equally well on more common wood types. They’re often not entirely long-lasting.
- Semitransparent stains will hide more of the grain, but they’re also longer lasting. They also do a better job of blending in blemishes than transparent stains.
- Semisolid stains are the next step up in transparency, and they do a nice job of blending the grains of various woods without removing the texture entirely. They’re also longer lasting.
- Solid stains hide the wood grain almost entirely. They’re excellent for using after replacing deck boards, shingles, or furniture. They also last the longest of the exterior wood stains.
Many of the best exterior wood stains come in different colors, allowing users to choose whichever hue best fits their aesthetic. Keep in mind, however, that there may be other reasons to choose one color over another.
If you’re considering a deck stain, remember that a deck will bake in the sun all day. A dark color will absorb a lot of heat, but dark colors are easier on the eyes than a lighter color. Light colors reflect more light, which can make them uncomfortable to look at in bright sunlight, but they often stay much cooler.
Likewise, a lighter color fence stain will brighten a backyard, while a darker stain might make a bright yard feel cozier.
