Wood has long been considered a timeless decking material, so it’s no surprise that it is still one of the most popular decking materials on the market. However, while it’s incredibly popular, it does require continual upkeep to keep it looking well-maintained. Traditional options for wood decking maintenance include clear sealer, stain or paint.
When it’s time to choose a finish for a deck, it’s important to understand the difference between available products to decide which is better for your specific project.
Should you paint or stain your deck? Much of the decision between deck paint or stain comes down to personal preference, the desired final look, and the amount of protection and coverage needed.
Is There a Difference Between Paint and Stain?
Although they do share some similarities, there are a number of differences between paint and stain, including their composition, amount of coverage and site preparation.
Paint is made up of four components — solvent, resin, additives and pigment. The solvent is the liquid part of the paint. In water-based latex paint, water is the solvent. Mineral turpentine is typically used as the solvent for oil-based paints. As the solvent evaporates, the other components are left behind.
Resins are the binders that adhere the paint to the surface after the solvent has evaporated. Additives are added to the paint to give it desired properties such as faster drying times, reduced mold growth or smoother brush strokes.
The color of the paint is due to the pigments. Different powdered colorants are combined with water and then added to the paint and mixed in different ratios to create a wide range of colors
The composition of stain is largely the same as paint — solvent, resin and pigments. Instead of the paint sitting on top of the surface, a stain is formulated to penetrate the wood and reveal the natural beauty of its grain and texture. Stain comes in three finish options — transparent, semi-transparent and opaque.
Opaque, or solid color stains, contain more pigment than the transparent or semi-transparent types and will cover the grain while still showing the wood texture. Clear stains don’t contain any pigment, allowing the true beauty of the natural wood to come through. Since they don’t contain pigment, they offer less protection than semi-transparent or solid wood stains.
If you’re having trouble deciding between solid or clear, then semi-transparent is the ideal compromise. It offers more protection than clear stain while revealing more of the wood grain and texture than solid stains. You can also choose the color that best compliments the home.
Many stains are oil-based, containing alkyd resins, linseed oil or tung oil or a mixture of the three. These stains penetrate the wood more deeply than water-based stains, but they can fade faster. Water-based stains may last longer, but they require more site preparation to prepare the wood to absorb the stain.
Benefits of Deck Stain vs. Paint
If the deck is made with pressure-treated woods, the stain will adhere better than paint. If pressure-treated woods are used, stain seeps into the deck, becoming a part of the deck rather than an added layer, which means that it won’t chip, crack or flake.
On the other hand, paint doesn’t flex as the wood of the deck expands and contracts in response to heat, cold and moisture, which can lead to peeling and additional maintenance throughout the year. To properly paint a deck, a primer should be applied first, followed by the paint — usually two coats — and then finished with a sealant.
Stain typically only requires one coat, and it can include a sealer to give you a sealed and stained deck quickly. It also adds a measure of slip resistance whereas paint can become slippery in wet conditions.
Paints offer a nearly endless range of colors and sheens, so you can choose a high gloss yellow, a matte green or anything in between. Stain is typically thought of as being wood-toned, but the truth is that stains can also range in colors from yellows to greens to blues. Stains can also be opaque, semi-transparent and transparent — giving you ultimate design flexibility.
How Often Should a Deck Be Painted or Stained?
Decks should be stained every few years to maintain the look and protection that stain creates on the deck. A painted deck will only need to be refinished about every 10 years.
However, regardless of the stated longevity of any products, it is important to inspect for damage, periodically. If the paint has chipped or peeled or the stain has faded, then it’s important to address these issues as soon as possible.
The longevity of paint or stain is also affected by deck maintenance. Quickly removing leaves, snow or other debris will protect the deck from moisture, reducing the likelihood of mold growth, peeling or fading.
