Railings are great. They really can make a difference to your outdoor space. But not as much as the deck itself. This single direct fixing of each deck board to the joist will ensure that normal thermal expansion and contraction can occur at both ends, but that the board itself stays in place.
Failure to do so may result in movement of the deck boards and uneven opening of gaps. Ensure the deck ends are aligned and if necessary use a rubber mallet or clamps to ensure a close fit to the neighbouring board. Repeat the process with the remaining deck boards.
To allow for board relaxation and thermal movement, the following gaps should be left when two 4 m boards are installed end to end. Expansion tables for all lengths can be found in the Technical Data Sheets — contact us for more details. To minimize gap size it is recommended not to lay deck boards end to end which are longer than 4 m.
If the whole length of the deck can be built by laying two boards end to end, and a wider expansion gap at the outer ends of the deck is acceptable, the boards can be installed with no gap where the ends meet, and the single direct fixing screws can be fixed where the boards meet instead of in the middle of the boards.
When deck boards are installed next to walls, please always leave a gap of 20 mm between the wall and the whole construction. Wider gaps may be needed for ventilation or to be in line with local building regulations as described in section 2.
For Piazza One oval holes may be used instead of using clips. Then loosely install the last two decking boards and tilt the inner edges upwards to provide enough space for inserting the appropriate final T-Clips, Wing Clips or alu rails. Matching colour Cover Strips are available for finishing the sides of all ProFi deck boards. Being flexible, they can be installed around curved deck surfaces.
The Cover Strip is attached by screws into the frame. The spacing between the screws must not exceed mm. For a robust and professional finish, ProFi Rail Step is available in matching colours for the Deck system.
Start Clips should be screwed into the edge of the frame at 60 cm spacing and the correct height to fit the Rail Step tongue. T-Clip large can be used to fix both the other edge of the Rail Step and the end of the deck boards. Remember also one direct fixing screw through the bottom tongue in the middle of the Rail Step. To create a closed deck surface and avoid leaves and other materials falling through the deck board gaps, a yacht deck like look can be achieved with ProFi Rubber Strip.
Press the rubber strip into the gap between the deck edges with a roller. After several days the ends can be trimmed to length. Rubber strip should not be used in the joints where deck board ends meet, and additional ventilation points are required when using rubber strip.
See section 2. ProFi End Caps with patented locking teeth can be also used to finish a deck made with Deck They are available in matching colours and fit both the deck boards and the Rail Step. If alu rail has been used in place of clips, and end caps are to be used, the alu rail always must be cut 10 mm shorter than the deck board length. ProFi Rail Step is a patented reversible profile designed for installation of stairs together with Deck boards. The bottom of the first stair riser is made by cutting a Deck board to 82 mm wide and installing it with a start clip at the bottom edge and alu rail at the top edge.
The top edge of the deck board and the Rail Step are then joined with alu rail and screwed into the frame. The stair tread is completed with a deck board and rail step that has been turned degrees which are also joined by alu rail and screwed to the frame.
T-Clips must not be used for stair construction. Remember also one direct fixing screw through the bottom tongue in the middle of each deck board and Rail Step. ProFi deck products have been designed with closed surfaces that offer greater resistance to spills and stains. However, as with any outdoor flooring surface, periodic cleaning and correct care is needed to ensure that the deck retains its beauty for many years.
Call utility companies in the area to find out if there are any underground cables, wires or pipes. Builders are often helpful with this information. Stay safe.

Test the screws. The screws you use should be specifically made for composite decking. If the screws do end up mushrooming, you should switch to another brand. When searching for the right screws, go to your local hardware store or home center and ask if they sell screws specifically designed for composite wood.
Composite screws are guaranteed to work and will give you the best-looking results when installing NewTechWood products. Install all screws properly. Never toe-screw in the product.
If you cannot drive in a screw at a degree angle into the board, you should add an additional joist. Flatten your deck joists. You can do this by stretching chalk lines over the joists, finding the high spots and planing them down with a power hand planer.
This decking product is not meant to be used as beams, columns, support posts, joist stringers or serve any other supporting function. Do not install over other decking boards. NewTechWood products work well with retrofits, but under no circumstances should they be installed on top of an existing decking material. There must be air flow under the decking. You must install the decking product on top of a substructure that consists of a frame to ensure there is proper airflow underneath, as this will prevent the absorption of too much water.
If an excessive amount of water is absorbed in an area that is not protected by a cap layer, this could lead to swelling. There must be at least four inches of free area underneath the surface of the decking so that air circulation can occur and promote drying and drainage.
Dig holes for the caissons using a posthole digger. Then, pour concrete in the holes and, using a float, smooth it over. Wait 24 hours so that the concrete can cure. Install a ledger board and beams. Using a level, attach a ledger board to the house, which will serve to secure your deck to the wall of your house.
A center beam should then be attached to the post hangers. Finally, attach an end beam. Attach joist hangers. Every six inches along the end beam and ledger board, put in joist hangers.
Using the framing lumber, create a joist jig to make sure there is consistency in your hangers. Your joists should be marked and cut so that they run from the end beams to the ledger board. Place the joists in the hangers and secure them with nails. Make sure to check the level, plumb and square frequently.
One box contains 15 locking clips and 75 T Clips. The locking clips serve to fasten the deck boards to the joist to prevent movement, whereas the T Clips allow expansion and contraction of the deck boards. It is critical to use the appropriate clip for each joint, as the deck needs to expand and contract properly without buckling or warping. The Mini Gap System. A box contains 15 locking clips, which prevent lateral movement and 75 clips that permit it. You can get starter clips, which are sold separately, which are to be used on the first and last boards as well as the stair treads.
A starter clip box contains 25 starter clips and screws. This way, they will expand away from the joint. A breaker board: The fourth and final situation is if a breaker board is installed between the rows, which would eliminate the butt joints. In this scenario, you must install the locking clips in the center of each board, which is similar to the first scenario. You can choose to have either side face up. This is the main board for most decks, and keep in mind that this type of board can only be fastened with the hidden fastener systems.
Screws cannot be used, so this type of board should not be used on stairs. Magellan Board: You can install this solid board with either side facing up. To secure these boards, you can use either the hidden fasteners or composite deck screws. Cortes Board: This board features a solid profile and contains no grooves. Each side features a different pattern, and these boards can be used for stair treads or regular deck boards.
They are attached using composite deck screws. You can rout them to accommodate hidden fasteners, but you should not rout them for the full length of the board. Columbus Board: This solid board contains one groove on one side to accommodate the hidden fasteners and another underneath to accommodate the starter clips.
