Not only about great quality and look. The procedure for installing your decking highly contributes to meeting the expectations of the customer. Carefully following the installation guidelines significantly limits the risk that the wood, a natural living element, might move, therefore compromising the overall tightness of the floor. We recommend that you read carefully the following requirements.
If you encounter any questions or concerns during the design or installation, please do not hesitate to contact us and we will be happy to offer you all the assistance needed.
The general instructions about the installation of joists are suitable for hardwood as well as Ultrashield and Décowood. The specifica instructions for Ultrashield and Décowood installation are in the next few pages.
The ground floor must be made flat with a slope of about 1 cm per linear meter. To correct an uneven slope you can use “compensation heels”- is wooden pieces derived from the same joists and fixed to the ground and/or to the joists.
In case of installation on unstable ground (Fig. 1) it is necessary to level the surface (in case of installation on soil, spread a layer of fabric to prevent the regrowth of the grass). In order to stabilize the surface upon which the joists will be layed, it is necessary to use concrete beams sized 30×30 cm (Fig. 1). It is recommended to build a double frame with two perpendicular rows of joists (Fig.1), the first with 1 meter distance, the second with a distance of 30 cm (in case of installation with clips) or 45 cm (in the case of installation with screws): this will make the structure perfectly stable.
In order to achieve the best stability, Déco recommends to build the substructure in durable wood, even in case of different heights and uneven soil. This recommendations applies in case of installation of hardwood decking as well as Ultrashield or Décowood.
For a proper installation of decking, it is important to wash the boards before proceeding. This is to ensure that the tannins in the wood is released therefore preventing it from staining the areas adjacent to the pavement.
There are two ways to install decking: with visible screws and with clips.
The clips do not allow the boards to be directly fixed to the joists, thus exposing the flooring to the risk of movements. This type of installation is therefore recommended only with proven stability woods.
Moreover, the inspection and / or replacement of damaged boards will be very difficult with this type of installation.
The procedure is as follows:
Once decking is installed, it is recommended to apply two coats of exterior oil, 72 hours one after the other. This operation, to be repeated every 6 months/1 year depending on weather conditions, it is necessary to preserve the colour of the wood and prevent it from cracking, especially on the ends of the boards. On the other hand the lack of this kind of maintenance does not affect the stability of the floor at all.
