Decking planks might wear out long before the deck’s foundation when exposed to direct sunshine or heavy rains. Because most komposittrall have wood foundations, placing composite planks on the deck will be simple. However, it is necessary to remove the old deck boards first for various reasons.
Remove the Wood Decking
Installing new decking planks directly over the old ones might save you two or three days of labor, depending on the size of your deck. One major reason to avoid this is that the deck foundation may not be able to support the additional weight. A third concern is that water seepage under the new boards will decay the old ones, making the surface unstable.
Composite Board Installation
Before installing the new kompositbrädor, make sure the joists are level after removing the old decking boards. If the decking is bent, the joists are likely to be as well, and you may need to replace one or two of them. Hidden fasteners, which screw into the joists and hook into grooves on the sides of the boards to keep them down, are the ideal technique to install composite boards. 3-inch deck screws can also be used to secure composite boards to the joists. When attaching composite boards, avoid using nails since the heads of the nails do not sink well into composite materials.
When building a deck, what are sleepers?
Due to the influence of moisture on wood, extra measures must be taken while building a deck. Extra pieces of wood called sleepers are one approach that builders have devised to slow the development of rot. Sleepers let homeowners create decks with less effort and in narrow locations where heavy digging is not possible.
Materials
Although sleepers are available in a number of materials, only wood sleepers are commonly utilized in deck construction. Concrete and metal sleepers are excellent for retaining walls, but they are too difficult to connect standard deck boards to for a simple deck.
Function
Between the deck surface and the ground or slab below it, sleepers are put. The decking is supported by sleepers, which enable moisture and air to circulate beneath it.
Benefits
Your chosen hardwood materials are kept off the ground by sleepers. This allows homeowners and builders to easily construct a deck without having to construct a whole structure to support it.
Problems
The majority of deck sleepers are pressure-treated with a variety of hazardous chemicals. Creosote-coated railroad ties are popular because of their low cost and ability to be recycled. According to the US Environmental Protection the chemicals used to make this lumber rot- and insect-resistant offer health risks to anyone who spends a lot of time with it. To avoid chemical exposure, use treated wood for the sleepers only when they can be entirely covered with decking.
