Before You Buy a Deck Resurfacer
When shopping for a deck resurfacer, it’s important to understand the difference between a deck stain, a deck paint, and a deck resurfacer. You might find the other options are better suited for your needs.
- Deck stains penetrate the wood, often changing its color but also accentuating the grain. Deck stains contain protectants that seal the wood from rain and snow, as well as minimize the effects of UV rays. They’re ideal for newer decks that still look good but need a protective finish.
- Deck paints create a thin shell over the deck, changing the color and protecting it from the elements. Deck paints do an admirable job of making the surface look even and uniform. They’re suitable for older decks, but the coating isn’t very thick.
- Deck resurfacers are ideal for older decks that are past their prime. These products create a thick coating on top of the deck that fills depressions, fastener holes, and pronounced grain.
An important note: There is no fix for an unsafe or compromised deck. If you’re dealing with rot, severe warping, or other structural issues, it’s best to replace the surface.
What to Consider When Choosing the Best Deck Resurfacer
There’s nothing quite like a fresh deck surface to enjoy with friends and family. And with the best deck resurfacer, your guests won’t even know an old deck lies beneath that beautiful coating. But choosing a deck resurfacer can be complicated. The following section will point out the most critical points to keep in mind while shopping for one of these products.
Deck resurfacers contain certain ingredients that make them suitable for particular uses. For example, many resurfacers include a gritty texture that creates a nonslip surface and fills cracks and gaps. This grit goes a long way toward creating a safe deck with a uniform look.
Other resurfacers might include rubberized polymers or polyurethane. Both of these materials create a flexible coat that can even self-heal in some circumstances. They’re also grippier than other finishes.
Some deck resurfacers contain mildewcide, which helps prevent mold and mildew from growing on the surface—a big plus for decks in shady and wet spaces.
The main reason deck resurfacers work so well for their intended purpose is that they’re incredibly thick compared to paints or stains. This thick material sits on top of the wood and self-levels, filling into the worn grain, knots, and fastener holes. It also resists damage from foot traffic and patio furniture.
Although much thicker than paint or stain, it’s essential to understand that most deck resurfacers need at least two coats to truly replenish the look of a tired old deck. The first coat will fill those undesirable areas while the second (or third) coat makes them all but disappear.
The one downside to deck resurfacers is their thickness doesn’t allow them to go nearly as far as a stain or a paint during application. In fact, DIYers can expect to use at least twice as much deck resurfacer for a given area than if they were to use a stain.
One gallon of the best deck resurfacer will usually cover only about 75 square feet. And, if the deck is particularly worn, a gallon might not even come close to that level of coverage. However, while the lower coverage might make the job more expensive than staining or painting, it’s still much cheaper than replacing the decking.
Color and Finish
The greatest benefit to deck resurfacers is that the sky’s the limit when it comes to color. Because these products are so thick and designed to hide the wood, manufacturers can offer them in a host of versatile hues. Browns, reds, greens, grays, and even black and white are available, and they can help blend a deck into the landscape around it.
There’s also a choice of finish when selecting the best deck resurfacer. Those who prefer a nonslip surface will enjoy the gritty, grippy textures. For those who prefer a smoother surface underfoot, these options are available as well. But, should you choose a smoother finish, recognize that it might not do quite as well at hiding imperfections as a grittier finish—an additional coat might be necessary.
All deck resurfacers protect deck materials from weather conditions like rain and snow. After all, water can’t permeate a shell of two or three coats of resurfacer. But there are other considerations to keep in mind.
If the deck is in a shady spot or an area that sees a lot of water exposure, a resurfacer containing mildewcide might be the only way to keep it clean and safe to walk on.
Also, keep in mind the amount of direct sunlight the deck sees when choosing the deck color. Dark colors might do an excellent job of creating contrast or hiding imperfections, but they also absorb a lot of heat from the sun. The deck surface could be uncomfortable to sit on and painful for bare feet or four-legged family members, particularly on hot, sunny days.
Deck resurfacers rarely dry quickly. Since you apply them in such thick coats, they take quite a bit more time to dry than a thin paint or even thinner stain. Most of the best deck resurfacers take between 24 and 48 hours to dry fully.
Because they take so long to dry, it’s important to plan the application when the weather cooperates. Imagine spending all day resurfacing a deck only to have rain come through a few hours later and make a mess of the deck and the yard. When applying a resurfacer, having 3 days of pleasant, dry weather is ideal.
Prep and Application
There are lots of pictures of DIY deck resurfacing jobs that appear to be peeling. In most cases, this is due to the DIYer’s failure to prep the surface and apply the product correctly. For optimal application, follow these instructions:
- Make any necessary repairs, including removing rotten boards or screwing down loose boards. Unlike refinishing a deck, there’s no need to sand or plane any of the surfaces unless large splinters are present.
- Clean the surface with a deck cleaner, a bucket, and a brush. Using a pressure washer is another option, but DIYers will have to wait longer for the deck to dry.
- Let the deck dry in the sun for around 24 hours—the surface must be dry for the resurfacer to adhere.
- Coat the surface with the resurfacer using a long-handled roller and a brush for tight spots. Be sure to maintain a wet edge to avoid lap marks.
- Apply the first coat and then let it dry according to the directions.
- Apply additional coats as necessary.

FAQs About Deck Resurfacers
Even though all this information should’ve taken you below the surface on the best deck resurfacer, questions might be popping up like splinters on a hot day. The following section will aim to answer them, as it’s a collection of some of the most frequently asked questions about deck resurfacers.
Q. What is deck resurfacing?
Deck resurfacing is a method of adding new life to an older deck by covering the worn surfaces with a thick layer or membrane of nonslip material.
Q. Is it safe to resurface my deck?
If your deck is suffering from rot, dry rot, splitting, or other issues affecting structural integrity, it is not safe for resurfacing. Resurfacing is for solid, affixed decking boards that are a few years past their prime—not structurally compromised decks.
Q. How long will my deck restore last?
Because the membranes are so thick, deck resurfacers can create a deck restoration that lasts more than 10 years without additional applications.
