Will Trex decking warp?

Trex decking resists termites, won't rot, warp, or splinter-and never needs staining or painting.

Why is my Trex deck warping?

Warping occurs when the decking's surface is exposed to sunlight. The decking becomes hot and starts to distort gradually. It happens during thermal expansion when the decking absorbs heat from the sun and expands. The heat from the sun causes the decking to be flexible.

What causes composite decking warp?

The reason why most composites warp is due to thermal expansion. When plastic fibres of the composites get heated, they will expand. It will return to its original size unless there's a problem with the decking board spacing.

Should composite decking warp?

Your composite deck may not warp, but it can sag and buckle. Most sagging is caused by improper spacing between the joists when it is installed. Also, thermal expansion, the fluctuation of temperatures, can have a more significant effect on composite decking than on natural wood decking.

What are the disadvantages of Trex decking?

Does composite decking warp or twist?

What is the downside of composite decking?

Cons of Composite Decking

Durability comes at a cost, as composite decking is more expensive than wood. It could cost 15 to 20 percent more for composite material than pressure-treated pine. Composites aren't natural. No matter how much effort goes into making composites look like wood, they're not.

Why is my composite deck wavy?

Flatten Joists to Avoid a Wavy Deck

Most PVC and composite products aren't as rigid as wood, so they don't bridge imperfections in the framing as well. If some of your joists are higher than others, you might end up with a wavy surface.

Does Trex decking float?

Water Resistance

Because plastic decking is lighter per cubic inch than wood, it will float easily. There are no micro-spaces for the water to seep into, which means that the material will float indefinitely.

Does Trex deck swell?

All of our composite deck boards have been engineered with the changing weather conditions in mind, meaning they can withstand whatever's thrown at them a lot better than real wood can. Composite decking doesn't swell or contract to the same extent that real wood decking does (especially if it's fitted correctly).

How long does Trex deck last?

Trex and TimberTech Composite Decking Warranties

Composite decks have a lifespan of at least 25 to 30 years — and they have warranties to match. At Keystone Custom Decks, we primarily build using Trex and TimberTech composite decking products.

Does composite decking twist?

Composite decking has a high rate of expansion and contraction due to temperature swings. It actually moves greater distances and more unexpectedly than traditional wood. When the boards expand and contract, they may split, delaminate, and peel. The movement can cause your decking to shrink, warp, twist, and bend.

Is Trex decking worth the money?

Trex decks are worth it because you get what you pay for. They cost more than a treated lumber one, making up for your extra outlay of cash at the onset, and will last for years longer than the average treated deck, letting you more than recoup your investment. Trex decks are also low maintenance.

How do you straighten a warped composite deck?

Cut off the warped part

When the composite decking warped, we can see that it's mainly the end part warped. So it just needs to cut the end warped part off. Then, we can put the same new decking board onto the empty part only. Please make sure that there is a suitable joist frame under the old and new decking.

Do composite deck boards expand and contract?

As temperatures fluctuate, composite deck boards will naturally experience thermal expansion and contraction. That's why the board ends should never be installed tight against one another.

What voids a Trex warranty?

If the surface of the Product is damaged or punctured, this warranty will be voided. Paint or Other Materials Applied to the Product: If paint or other coating materials are applied to the Product, this warranty will be voided.

Can underside of Trex get wet?

Does composite decking expand when wet?

Yes, composite decking materials expand and contract in all directions, but not as much as real wood. Composites are resistant to moisture.

Does composite decking puddle?

In short, no. Standing water on composite deck boards will not affect your TimberTech® capped polymer or capped composite deck boards the way it would traditional wood.

Why is my deck bowing?

Just like warping, bowing occurs when moisture leaves the boards causing the wood to shrink. By adding moisture back into the wood, you can correct the warping with a little bit of pressure. Add water to the board until it starts to pool. Leave it sitting on the surface for roughly 15 minutes before wiping it away.

Should a composite deck be level?

While you could keep a composite deck level, some water would stay and eventually evaporate. Either way, a composite deck requires little or no slope. If your deck is not attached to or next to any structure, then sloping your deck still might be advisable if only to shed water off the deck boards more efficiently.

Can Trex decking be repaired?

If you notice a scratch or damaged area on your Trex decking, fret not! If you have a small scratch or chip, use a composite deck repair kit. If you have a larger scratch, dent, or dings, it is best to replace the entire board. With a few tools, you can easily repair your deck and enjoy your patio.

Do you need to slope a Trex deck?

“When installing Trex Porch Floorboards in a non-covered environment, the porch structure should be slightly sloped to help allow for proper drainage. Joists should be sloped 1/8″ per foot away from the house to facilitate drainage.”

Can composite decking crack?

It can crack if the deck suffers stress due to a settling foundation or a poor design. It may also crack due to simple wear and tear or faulty pieces. Manufacturers have developed a product specifically designed to patch cracks in composite decking.

Is Trex decking slippery when wet?
