if you have a structure that has plywood siding as a covering, it may become damaged if it was not properly treated or has been exposed to rain for too long. Fortunately, replacing plywood finding is a relatively simple task that makes an excellent DIY project. In fact, you can replace a piece of water damaged plywood siding in a short period of time. Better still, you can use this handy how-to guide to learn everything you need to know about replacing water damaged plywood siding.

Step 1 - Remove the Water Damaged Plywood Siding

After you have located the sheet of plywood siding that is water damaged, you'll need to remove it. To do this, locate the seams around the 4 by 8 foot piece of plywood siding that are filled with caulk or silicone sealant. Then, take the utility knife or scraper and dig into the caulk so that you can score it and loosen it. Then, take a pry bar and hammer and pry the edges of the plywood siding out. Be careful not to damage the adjacent pieces of siding or you will need to replace them as well.

Step 2 - Remove Nails from Studs

When prying out the old piece of plywood siding, you will probably leave some nails in the studs that secured the siding. So, take the nail puller or hammer and remove the nails so that you can install the new piece of siding.

Step 3 - Clean Up Edges of Adjacent Siding Pieces

Once you remove the water damaged piece of plywood siding, take the utility knife or scraper and clean up the edges on the other adjacent pieces of siding. There will probably be ragged edges because of the caulk or silicone sealant that was used to seal the siding. Take the utility knife or scraper and run along the seam edges so that they become smooth.

Step 4 - Insert New Siding Piece

Have someone help you insert the new piece of plywood siding into the area from which you removed the old water damaged piece. Have your assistant hold the piece of plywood siding in place while you grab your hammer and nails.

Step 5 - Nail and Secure the Piece of Siding

Take your hammer and nails and begin nailing the new piece of plywood siding securely to the studs. Be sure to nail into the studs and not open areas behind the siding piece. To help locate the studs, look for nail marks on the adjacent pieces of siding.

Step 6 - Caulk the New Piece

Once you have nailed the new piece of plywood siding into place, take the caulk and caulk gun and run beads of caulk along the seams of the new siding peace.

Step 7 - Paint or Stain

You will now need to paint or stain the new siding piece to help it stand up to the elements. If you have previously painted the other pieces of siding, attempt to find a color that matches. If you have not painted the other pieces of plywood siding, that is probably the reason for the water damage and you may want to consider using a good waterproof sealant or paint on your structure.
