clips and screws• Easy to work with using standard hand tools• Very durable; water and moisture resistant• Splinter free product• Limited maintenance required• Will not warp, twist or crack

SLIP RATING• Rated as ‘low slip potential’ when independently tested to BS7976

part 2 to conform with UK slip resistance guidelines.• Tested with Type 96 4S Slider and Type 55 (TRL) slider in both wet and dry conditions.

CLEANING AND MAINTENANCE • To maintain the original finish of the decking, clean the board

regularly with soap and water.• No sealing or painting is required, however, the product can be

painted with a standard timber treatment product.

GUARANTEE • Wood Composite Decking comes with a 10 year warranty.• The decking has strong resistance to weathering; however, the

FIXING INSTRUCTIONS

NOTE: THIS PRODUCT SHOULD NOT BE FACE FIXED USING NAILS OR SCREWS AND SHOULD ALWAYS BE SECURED USING THE PURPOSE MADE CLIPS AT EACH JOIST.

Wood Composite deck boards are subject to expansion and contraction when exposed to variations in temperature. To accommodate for this potential thermal movement:• Allow a 30mm expansion gap around the perimeter of the deck giving consideration to all walls, posts and other obstacles.• Allow a 10mm expansion gap between the ends of boards.• To prevent ‘creep’ secret fix each board with a single screw, positioned half way along its length, angled at 45 degrees and fixed through the bottom lip of the groove and into the joist or bearer.In addition:• To aid water run off prepare the sub-frame to accommodate a fall of 2mm per metre along the length of the deck boards.• Fix joists/bearers at a maximum of 40cm centres when boards are fitted perpendicular to the joist direction. When boards are fitted diagonal to the direction of the joist/bearer provide supports at 30cm centres.• If the deck is to be raised or used for commercial use, seek guidance from a qualified engineer to ensure the structure is sufficient to carry the potential loading.

Preparation of site:

Prior to laying: Preferably to be used on a hard sub-grade. In case of use directly ongarden soil always place paving stones underneath the rails to create an extra strong foundation (see image 1). In that case level the ground first and remove possible weeds anduse a black anti-weed membrane to prevent as much as possible weeds from growing. Keep a minimum gap of 30 mm between decking / rails and walls or other obstacles. In order to absorb the longitudinal effect of the WPC decking by influence of temperature changes, please keep an opening of about 10 mm between the crosscut faces in case of use of several sections of decking in the longitudinal direction of the terrace.

Step 1

Lay the rails (base structure) flat and level (see image 6), at a maximum interval of 30 cm.Make sure the terrace during the longitudinal direction of the deck runs just under a slight inclination of approximately 1 cm per meter so that rainwater flows away from the terrace. At the beginning and at the end, position two planks at a distance of 18 cm between the axes. TIP: Keep decking 2-3 cm longer and cut to size after installation, using a circular saw. Then fit the finishing profile. This will give it a very neat finish.

Step 2

Place a finishing profile (A-vertical) against the head of the rails (A-horizontal), see image 2. Cut this finishing profile with a false mitre. Note: follow the drawing (see images 7 and 8), so that the finishing profile connects with the so-called crosscut face later. This too must be done exactly according to the drawing.

Step 3

Now install the first section of decking (B). Make sure that the tongue of the finishing profileand the groove of the decking interlock and connect correctly. Now screw the finishing profile to the decking into the marked v-grooves every other 40 cm, using the enclosed long screws. Beware of the power of your electric screwdriver (see image 3).TIP: for additional stability, the horizontal rails can be screwed onto the vertical finishing profile using angle irons (see image 9).

Step 4

When the first section is in place, place a clip (C) on each rail, in the groove of the decking.Make sure they connect well and then (semi-) tighten/untighten the clips to the rail, using the enclosed short screws (see image 4). You can now install the second section and repeat the above instructions until you have created the size of terrace you want. Once the entire terrace is in place, tighten all screws and clips.

Step 5

Once the final section is in place, you finish with a finishing profile (A-vertical) on both thelongitudinal side and the so-called crosscut face. Now cut the longitudinal side of the profile to be connected with a false mitre. Note: follow the drawing (see images 7 and 8), so that the finishing profile connects with the crosscut face later. Make sure that the rails (A-horizontal) are cut to the right length, so that the decking slightly protrudes (by about 8 mm) and the finishing profile connects nicely (see image 5). Now screw the finishing profile to the decking into the marked v-grooves every other 40 cm, using the enclosed long screws (see image 5).TIP: For an extra neat and strong attachment of the finishing profile, we recommend you attach another bottom rail to the crosscut faces of the bottom rail at a right angle, using the angle irons as described under step 3. In that case you must keep the bottom rails 50 + 8 = 58mm shorter than the end of the last section of decking. Once the last section is in place, you can fully secure the finishing profile (see image 10).

Before securing the finishing profile to the crosscut face, please note the following:• make sure you “turn” the profile in relation to the profile on the longitudinal side before you start cutting (see image 6). • now follow the drawing (see images 7 and 8), and cut the connecting finishing profile for the crosscut face with a false mitre.• then screw the finishing profile to the underlying rail into the marked v-groove every other 40 cm, using the enclosed long screws (see image 6).Tip: Not suitable for load-bearing structures.
