To put an end to your worries of the warped deck, we’ve arranged a few steps that might be of great use to you today. So, let’s have a look at them sequentially-

Step 1: Select The Wood

This trick that we’re going to share with you today is the best way to deal with a warped deck. You’re going to need a piece of wood first.

You need to make sure that the wood you’re choosing is strong enough. It should be strong enough to handle a decent drill easily.

As it’s required to be very strong, also make sure that it’s not wet. Because that will automatically soften most of the wood pieces for you.

Step 2: Shape It Perfectly

Now, this wood will be used as a clamp soon. More like you need to transform it into one clamp.

But first, you need some adjustments with the size of this wood. You need to cut the wood totally flat.

It should be long enough to cover the width of two of your decks’ width. So, measure the width of the deck and cut it accordingly.

Also, remember that the height of the wood should not be more than the half of a screw. It means a screw should have at least half of it uncovered after going inside the piece of wood.

Step 3: Drill a Screw in The Wood Piece

If the wood is in the correct shape, you need to drill a screw in the middle of the wood piece.

But remember to use a washer that will prevent the top of the screw from going inside the wood.

Also, you need to drill the screw half first, because soon the other half of the screw will be inside your warped deck.

Step 4: Place The Wood Piece On The Deck

You need to place the wood piece on the warped deck now and this part is a bit tricky.

Start by placing one side of the wood piece on the middle point of one board. The ending point of the wood piece will be on the middle point of the deck board on another side of the warped board.

The length of the wood piece will be covering from one middle point to another middle point of another deck board. That’ll also cover all of the warped deck board.

The screw on the wood piece will be at right at the top of the warped deck board.

When you put the piece right at the place, you’ll notice how much the deck has warped. All you have to do is just look under the wood piece and you’ll see the gap.

Step 5: Drill The Screw To The Warped Deck

Grab the drill and drill the screw all the way to the warped deck board. You’ll notice that instantly the warped deck is leveled and the wood piece is working as a clamp to hold it.

Step 6: Drill The Side Decks

Immediately drill holes at 45 angle on the side decks that’ll connect the leveled boards together.

Make sure that you drill as close as possible to the warped deck. Also, remember to drill from both of the sides.

Step 7: Put The Screw Inside The Holes

Now, you need to take screws and put them inside of each hole. Make sure you drill them in perfectly in the holes so that there’s no room for those to move.

These screws will be used as a support that’ll hold the deck flat like the ones next to it.

Step 8: Take The Wood Piece Away

If you have a flat deck now, you can unscrew the screw that you entered the warped deck with the wood piece. There you go, your flat composite deck just like new again.
