Laying Composite wood decking & Underlay in Easy Steps

Why use wood plastic composite decking for your house?WPC decking is undeniably one of the most useful inventions. Made to have the appearance of natural stained wood decking, composite wood is more affordable, does not need to be nailed in place, doesn't need finishing treatments, and is damage resistant. Options in composite decking are numerous and vary his design from wood grain replication, to mimic ceramic tile. Although composite wood decking still contains wood from our natural resources, the majority of the material used in composite wood decking contains no wood and bonds together in several layers in a process using high pressure and heat. The benefit of using composite over wood decking is that the various layers of cellulose fibers will allow expansion and contraction during humidity changes. Areas that contain high humidity levels like bathrooms are not suitable for composite decking.

Getting Started.

Once you've made your choice in what type of wood plastic composite decking design you want to see in your home, you'll need to pull together some basic tools for the job. Materials needed obviously include your composite wood decking, and if you have chosen a variety that does not come with underlay attached to the planks, you will need to buy some rolls of underlay as well. You'll also need protective sheeting, composite wood adhesive, molding or a baseboard, and threshold transitions. Basic hand tools include a hammer, a crow-bar or pull bar, spacers to use between sections of decking or between walls and decking, safety glasses, utility knife, gloves, a tape measure, power tools such as saws and drills, and some Composite wood cleaner. You may not necessarily need all these items, but they are handy to have should the need arise. Most of these tools are available at your local hardware shop, and many shops sell composite wood decking installation kits which include the tools most needed for the job.

Composite wood decking installation. Before you begin to install your wood composite decking, you must ensure your work surface is flat and clean. Remove any uneven areas that will affect your flat surface with a paint scraper, a putty knife, or, for stubborn lumps, a sander or grinder. Divots or dents should be made level with wood filler or crack filler and left the appropriate time to dry. Remove all trim and transitions from walls and doorways.

Underlay First

When you are ready to start putting your deck down, you must first start with the underlay.

Usually purchased in rolls, applying underlay is a very simple task to complete, and is essential in controlling excess noise. Roll the underlay out from one side of the room to the other and secure in place with adhesive strips found on the underlay, or tape. Returning to the starting point with the remainder of the roll, or the next roll of underlay, roll the next piece out across the room beside the last length of underlay and adhere the two pieces together at the seam, making sure to overlap them by approximately one centimetre. Continue until the deck surface is covered completely with underlay. Any excess can be cut away once the wood composite decking has been installed.

Decking

At best lay your WPC deck down in evenly, measure your room from one side to the other and divide by the width of one composite wood plank. Add the remaining amount to the plank width and divide by two in order to balance to the room. Leave a half centimetre or full centimetre gap between the wall and the first row of composite wood planks for expansion room. Beginning at one side of the room, place spacers along the wall the give you the expansion area. Set the first plank down and then the next, end to end, and secure in place. At the end of the first row, you may need to cut the final piece in order to fit it in. Subtract half a centimetre from the measurement of the space between the wall and the end of the last piece lay before cutting your final piece. Use the off-cut to start your next row unless it is shorter that 20 centimetres. Continue in this way until the room is nearly complete. The final row may need to be cut along its length.

The final steps of installing composite wood decking are the ones that demand the most patient. Cut the underlay so that it is even with the composite wood decking. Remove all spacers from the walls and install the molding or baseboard in order to hide the expansion gap. Remember to attach the molding to the walls and not the decking so that the deck is able to expand and contract as needed. Attach the transition pieces in doorways and level changes. Lastly, give the deck a gentle clean with a damp mop or some composite wood cleaner and sit back to enjoy your work.
