You can build a deck out of lumberyard plywood, but it will suck. A skateboard is usually made from 7 plies of wood, but they are in no way comparable to a sheet of plywood.
Can plywood be used for decks?
Given that it’s highly durable, pressure treated plywood is most commonly used to build outdoor decks, fences, and railings.
How thick should plywood be for a deck?
CHOOSING THE RIGHT DECKING BOARD THICKNESS
| Nominal Thickness | Actual Thickness |
|---|---|
| “Four-Quarter” or “1x” or “4/4” E.g.1 x 4, 1 x 5, 1 x 6, 4/4 x 6 | 3/4” to 13/16” |
| “Five-Quarter” or “5/4” E.g., 5/4 x 6, 5/4 x 4 | 1” |

What kind of plywood do you use for a deck?
What Type of Plywood is Best For Outdoor Use?
- Exterior plywood is weather (and water) resistant, so it’s strong enough to be used outside and also in areas that are exposed to water and humidity, like a garage.
- There are many types of exterior plywood to choose from — the most common being CDX or ACX.
What is the cheapest material to build a deck with?
Choose wood, but carefully: Untreated wood decks are generally the cheapest to install, but don’t forget long-term costs. Wood decks require yearly maintenance and deteriorate quickly if they don’t get it.
How do you waterproof a plywood deck?
Using an epoxy sealer is probably the most popular way to seal plywood against the elements. The epoxy is usually found in paint or spray forms. The advantage that epoxy provides is that it makes the plywood stronger, in addition to waterproof.
Can plywood be pressure treated?
Use of Pressure-Treated Plywood
Pressure-treated plywood is chemically treated to prevent insect damage and to protect against rot, and it can survive outside without added protection if exposed only to average amounts of water like an occasional rainstorm or garden hose.
What plywood is best for outdoor use?
Well, marine grade plywood is regarded as the best outdoor plywood, and is extensively used for construction. There are other construction materials that can be used for building exterior structures like oriented strand board (OSB) or ACX, but marine grade plywood outshines them all.
What to use instead of decking boards?
Decking Alternatives
- Natural Stone And Porcelain. Firstly, let’s start with one of the most expensive options.
- Poured Concrete. If you decide that concrete slabs are not for you, and you are looking for a super low-cost option, you could contemplate a patio made from poured concrete.
- Timber Decking.
Is plywood stronger than OSB?
OSB and plywood offer similar (and sufficient) performance in terms of strength and functionality, though plywood is about 7% stronger.
What happens when plywood gets wet?
When plywood gets soaked with water, it usually swells and will eventually rot. However, if your plywood does get wet, there is no need to panic as plywood usually takes at least a few weeks to decay, especially if you live in a cool and dry climate.
Does staining plywood make it waterproof?
Perhaps not the first thing you would think of when choosing how to weatherproof plywood, wood staining is one of the best ways to ensure that water doesn’t ruin your plywood, and just like an epoxy sealant, it will not cover up the natural finish of the wood.
How long will pressure treated plywood last outside?
It depends on the climate, the type of wood, its uses, and how well it’s maintained. While pressure treated poles can stay up to 40 years without any signs of rot or decay, decks and flooring might only last around 10 years.

Can you treat plywood for outdoor use?
And if you’re putting your plywood outdoors, it’s also really easy to waterproof! Plywood can be waterproofed with paint, polyurethane, or epoxy finish. Lightly sand the plywood with 180 grit sandpaper, clean off any sawdust, and apply the finish with a brush or by pouring the finish on if using epoxy.
Will painted plywood last outside?
Standard plywood is not rated for exterior use and paint will not adequately protect it from moisture.
How do Marines treat plywood?
Since marine plywood is typically used underwater, you’ll need to treat every surface of the wood with sealant. We prefer clear, penetrating epoxy because it works its way deep into the wood, dries transparent, and requires less maintenance than other types of sealant.
Does treated plywood rot?
Pressure-treating can make wood water-resistant, but it’s not 100 percent rot-resistant. Any time the wood moves, bends, or cracks, water can enter. While this may seem worrisome, the key is to keep the water away.
How much does a 4×8 sheet of plywood cost?
