+
Domi L-corner or bullnose board is optional for covering the ends or grooved edge.
-
8. Can I install your WPC product with another manufacturer’s accessories, like hidden fasteners?
+
No. Domi fasteners are recommended for use when installing Domi decking or wall cladding. Using another manufacturer’s accessories may result in an unsatisfactory installation, and void your warranty.
-
9. Can I use glue or caulk with my decking?
+
No. Do not use glue or caulk to fasten Domi composite boards or to seal between any of our boards. This will impede the drainage of the board and inhibit the natural expansion and contraction of the boards.
-
10. What would you recommend using for the understructure of a deck?
+
Domi composite decking works well with substructures made of a variety of materials, like natural lumber or pressure-treated lumber. Domi composite or metal joists are recommended are preferred as they are designed specifically for Domi decking.
-
11.Can you rip a composite decking board?
+
Yes. Our composite boards can’t be ripped to reduce thickness but can be ripped to reduce width.
-
12.Can I overhang your composite decking over the edge of my deck?
+
Yes. Domi composite decking may overhang over the edge of your deck, but overhang is not recommended to exceed 2 inches (or 50mm).
-
13. How do I finish a cut edge to match the color of my decking?
+
We provide L-corner or bullnose boards in the same color tone to match the color of your decking. In other applications, a solid color-matched stain or paint may also be used to coat the cut ends of the deck boards.
-

-
16.Can I use a nail gun to install your composite decking?
+
No. We do not recommend using nails or nailers, but using screws when installing composite decking. The material is very dense and getting nails to penetrate to a proper depth without bending can be a challenge. We recommend that all holes be predrilled to help reduce mushrooming, and avoid splitting. When using nails or nailers, the concern is that the ends would not be predrilled and possibly lead to cracking and splitting.
-
17.How much gap should I leave for expansion or contraction when installing?
+
As temperatures fluctuate, composite deck boards will naturally experience thermal expansion and contraction. There should always be a gap between the butt ends of the boards to allow for expansion and contraction and a gap between the edges of the boards for water runoff. For more information, refer to Domi Deck Installation Instructions.
-
18. Is ventilation required under a deck?
+
Yes. It is very important that there be adequate and unobstructed air flow under the deck to prevent excessive water absorption. Improve drainage or grade flat areas where standing water may gather. For decks with limited ventilation, 1 inch of clear ventilation is required.
-
19.How do varying weather conditions affect your decking during installation?
+
Domi composite decking performs well in varying weather conditions, having the lowest thermal movement among all wood-alternative decking. During installation, Domi decking will contract only slightly in cold weather. In hot weather, it expands. We recommend that the material is on the job site 48 hours prior to installation to acclimate. Follow the installation instructions on spacing guidelines to ensure proper room for expansion and contraction.
-
20. What is the maximum joist spacing for your decking?
+
Joist spacing requirements vary according to the product type you’ve chosen. You are advised to follow our Installation Instructions and local building codes.
-
22.Can I build a fire pit on your composite deck?
+
Fire pits should not be placed directly on Domi composite decking, it can cause damage to the surface of Domi composite decking via direct exposure to the flame, excessive radiated heat, or embers. But fire pits may be installed with a thermal insulating structure made of stone or other fire-resistant materials between the fire pits and Domi composite decking.
