Can You Install New Decking Over Old Deck Boards?

What To Do With A Graying Wood Deck

That’s usually an effective way to avoid prolonged moisture exposure for your deck. When all your joists are in , you can begin your decking. Many people think the selection of the width of the board is purely cosmetic or a function of price. However, the width of the board is crucial where dimensional stability is needed. The more narrow the decking board, the less it will move and the less it will cup. This is why in boat decking construction and flooring you will typically see a nominal 3 (actual 2.5”) or nominal 4 (actual 3.5”) wide deck board being used.

Hide Composite Ends

The wood stain complemented the new composites very nicely, and I predrilled the base trim and screwed it in place along the edges of the walls. We then added a Timbertech fascia board to the outside edge of the deck and stained the handrail. The homeowner chose to keep the wood handrail system and stain it to complement the new composite decking. However, the cap rail was in very bad shape, so it was replaced with composite. Some heavy-duty Irwin clamps helped to keep everything in position. Naturally, I ran into a couple of unexpected snags on this project. As a result, there was already evidence of wood rot at the deck intersection.

Build Decks Using Composite And Other Low

My favorite type of wood is ACQ Spruce for its strength; however it is not the most visually appealing. Countersink the screws but no deeper than the screw’s head. Besides creating a rougher finish, deep countersinking can reduce the effectiveness of the fastener and void the warranty.

Assess the joists for rot - You also need to examine the joists, as this dictates the strength of the decking. When the joists weaken, the entire deck can start to warp or sag. Joists often suffer from mildew and rot, especially when compared with other parts of the decking. This is because they are not exposed to the direct sunlight.

so i agree with the conclusion that decking on decking will promote rot and mold, so now my other question is part of my deck is covered by a porch area, like a sun room with a room. I was going to enclose this area and make a breakfast nook. Since it is covered do you all think i can lay a sub floor over the the existing deck to start my addition project. BTW - I also agree with the others that sandwiching decking materials will promote moisture damage and rot, etc. I might just lay down 3'x3' area of the trex and weigh it down with stones or bricks over maybe couple of seasons and see what happens. Having said that, ripping out old deck is not that hard. Nails are probably little loose anyway and having 4' bar makes it much easier.

It is also important that all screws be secured at a 90-degree angle to the boards. Fastening from the side can cause dimpling in the composite surface and mar the finish.
