All the nuances of laying decking (more commonly called PDK) painted in detail in the manufacturer's instructions, depending on the species of this relatively new material.And yet, the author believes that the article is useful to those who plan to carry out all the work yourself, but do not understand it well with the content of the instructions, especially if the board - imported.

no secret that some of the texts after translation in native Russian sometimes no common sense.Secondly, the proposed material can help homeowners assess their capabilities and determine the feasibility of the acquisition is terrace boards of wood-polymer composite, and not any other.

raw material for the production of WPC is crushed (to the state of flour) dried wood, which fractions are fastened by means of a polymeric binder.Plus - Various additives that enhance certain characteristics of the decking.Feature of products that it sells in the kit, which includes all the necessary elements for the installation on their own, without the involvement of specialists.

Basic rules for working with terrace board

Laying PDK is conducted only at positive temperatures.
air circulation under the decking should be effective.
As with any material, composite wood-polymer with temperature changes and humidity (to a lesser extent) is able to change its geometry.When installing terraced boards is necessary to consider leaving some clearance between samples.
in direct contact with the entire structure is excluded from the soil.

scheme It is with this and you need to start.Firstly, it is possible immediately, based on the area of the future deck linear parameters select optimal composite board.Second, determine the order of its installation.Third, depending on the characteristics of the site, to pick up all the necessary components.

For example, if you plan to composite wood-polymer shell out the garden path, you can immediately specify the slope terrain.So, to get the same support under the joists to provide the desired angle.In addition, if the finished circuit can always count on a substantive consultation.Terrace boards are sold in specialty stores, and managers are quite professionally versed in all the features of the PDK installation.

Tools

Working with composite complexity is no different.Depending on the specific placement need only what is practically at each host.

E / drill.
tool for cutting.Better if it will be a model of electric saws, then will cut much straighter.
screwdriver (if possible), as a screwdriver screwing fastener elements much complicate the work and reduce the composite speed of installation.
Building level and measuring tape (optional).
Screws (if installation is planned to conduct open pit).Moreover, not all, but only a coating (anticorrosive).

KDP

following rule holds whether to work with any material - it should "adapt" to the local conditions.Therefore, after the delivery of the composite and unpacking it is desirable to attempt to install no earlier than 36 hours.During this time, you can carry out a number of other preparatory activities.

the basis

basis

Typically, assembling decking associate it as a finishing laying flooring.However, wood-plastic composite can be used for walls, gables of buildings.But the requirements for any constant basis - evenness and reliability.Next will be the features of the flooring installation of the PDK, as it is this work causes the most problems.

Possible bases:

screed followed by treatment with the composition of bitumen;
lags;
joists.

If the decking is used as flooring, it is necessary to provide natural drainage of water from this segment.Excessive humidity under the composite reduces the term of its maintenance-free operation.Therefore playground designed for stacking boards should have a slope.What?

too large to be noticeable enough - does not provide a natural outflow of water.The best is the difference in height of the order of 0.8 cm to 1 PMflooring, although here we must take into account the dimensions of the finished surface.

To ensure that the bias is properly selected, simply install 1 board in the calculated position and lightly spray it with water.And then see whether to drop it stagnate or start to drain.Change the angle can not only by ties, which "lifted" in one direction, but also lags.

Installation lag

Under them settling solid ground.It can be a reliable screed (not less than 50 mm), asphalt pavement, slab w / w or paving slabs.On the slope it has already been said.How to fix them, it depends on the local context.Feature - at their disposal at the site.

As already noted, a composite of wood-polymer moisture does not accumulate.To the liquid dripping, logs are to be installed in the direction of the slope area.Interval - about 40 -. 45 cm

If for some reason this is not possible their installation, the mount is permitted in the other direction, even perpendicular to the slope.But in this case, the length of the small lag gaps are left between them (about 25 mm) for removal of the natural water.

Note

When installing flooring on an already finished monolithic foundation before installing the lag is necessary to cut it (hack) small Stroebe (channels) to drain fluid from the area.
Mounting guide only anchors.Given the specifics of operation of the deck, no other means (eg, screws + dowels) are not suitable.

Fixing boards composite

There are 2 ways of fastening.

samorezov

The decking board, in targeted areas, holes are drilled.Next - screwing fasteners in a log at an angle.

clamps (plastic or stainless steel)

plate screwed to a carrier support, and then inserted in its groove composite board.

Features

«Departures» end of the KDP for extreme lag should not exceed 50 mm.Failure to do so will have to put extra support.
Between the last in the series of composite board, and a vertical obstacle (for example, a wall structure) at a minimum gap is left at 10 mm.

final stage of installation

It is to assess the results, determining certain shortcomings (and correction).For example, minor scratches easily "cleaned" small fraction emery paper.

immediately installed additional elements - caps on the end of the decking (or strips) composite corners and so on.

If necessary mounting composite profile (strip) in place flooring bending (for example in the region of the columns on the nut), it should be heated slightly (optionally hairdryer construction).After that it lends itself to the deformation in any plane.

Common Errors in self-installing decking

Too small gap between the products.As a result - a composite deformed, and the floor bends.What target?1 p. M. Of terrace boards, on average, during the expansion, adds to the length of 0.5 cm. Therefore, make a calculation for a particular sample will not be working KDP.
large distance between joists.The best is 400 mm.The increase results in increasing the load on the composite, thereby bend it over time, and there are cracks in the stack.
Errors with the spatial orientation of the KDP.Terrace boards stacked in a certain direction, and the majority of manufacturers in the end portion of the sample is applied to the directional arrows.If this is not taken into account, the flooring of KDP can turn striped.
Using log of wood.Buying composite, it is necessary to buy the corresponding supporting elements (joists polymer or metal).Typically, sellers always pay attention to it customers.For example, products Y50-85 (98), K30-51.The point differences between the coefficients of expansion of the KDP and wood.With rapid temperature changes, the design of the different materials will begin to break down and have to regularly repair the flooring.

Short leg fixture.As a result - the lack of fixing strength composite joists, resulting in loosening of boards.This flooring will last a long time.
Acquisition of structural components from different manufacturers.Take into account that in most countries there is no such a thing as a guest.All major companies are developing their own standards, not running counter to generally accepted requirements, for example, the rules of the European Union.Consequently, there may be some discrepancies in some parameters.This will not only complicate the installation of composite boards, but also directly affect the final result in the form of cracks, bumps and the like.
