DECKINGPRODUCT GUIDEINSTALLATIONCARE & MAINTENANCE

COEN WPC is a new type of composite made by mixing 60% wood powder with 28% HDPE and 12% additives. These are extruded through our modern CNC high pressure / temperature extrusion machines. Our WPC not only has a high degree of anti-UV and weather resistance, but is also easy to work with and install. COEN WPC’s are highly resistant to moisture, so there is no “Wood Rot” and termites just don’t seem to like getting near our products. No cracking, warping or splintering ensures an efficient and easy installation process for our builders. We also have a very stable UV product, so the colour will have very minimal fading from the harsh Australian conditions.

Our WPC is a safe, environmentally responsible alternative, and doesn’t require any painting or coatings to ensure colour or longevity. The main materials used are wood powder, from scrap building and factory waist, such as wood furniture and construction manufacturers. In addition, we recycle any off

cuts or waste from our manufacturing process. The aim here is to improve our environment through recycling.

The raw material quality is paramount to our product being consistently manufactured to the specifications, to ensure the products longevity. As such we only select quality raw products and each batch is tested to our required standard prior to entering its first stage of production process. (Ref our web site for the production process).

After production, each batch of COEN Composite Wood is tested for its elasticity and strength. Our products have a consistency in size and colour and are cut to a length you need, therefore eliminating the search for the perfect piece of WPC for your application.

Prior to beginning the installation process, check any substructure is true and to the design criteria and that the correct code compliance for building the substructure is assured.

DECKING INSTALLATION

HOLLOW SOLID

DECKING TYPES

INSTALL TIPS:• Most colored chalk lines are permanent. Use baby

powder.

• When drilling large or deep holes, periodically lift the bit out of the hole to remove the shavings.

• Observe minimum side by side and butt join gapping requirements.

• Always pre-drill when screwing or fixing near the ends of the boards. Each pilot hole must be greater than the ‘outside diameter’ of the screw thread.

DECKING INSTALLATION

First, pre-drill the joist, then screw in the starting clip. Slide the first board onto the starter clip, horizontally.

Continue to slide the decking boards and clips into the grooves of the previous board and secure with the decking clips and screws to the joist.

For hollow decking, drill a small hole around 5mm at the end of each board to allow for water drainage, then attach end caps by lightly tapping into the decking board ends.

Calculate the decking span and joists to make the frame of your deck. Ensure joists are spaced and secured as per Technical Information table on page 4. The frame needs to be level with a slight taper away from the dwelling, allowing for water flow.

Insert the decking clip onto the first board then slide the second board into place against this first decking clip, then lightly screw down the decking clip, around halfway. Once the first board and the second board are in place, tighten fully the decking clips to secure the joint between decking board

Pre-drill pilot holes at an angle through the grooved edge of the deck board and onto the joist/ ledger board. Insert screws into the pilot holes to secure the last board. Attach a fascia board flush with deck surface, and allow for thermal expansion.

CODE COMPLIANCEJoists must be spaced on centres according to the following charts for Solid & Hollow Decking. Be sure that joists are level and plumb. COEN decking must span at least three joists.

For heavy items such as hot tubs, planters, etc., consult a local building engineer or inspector for span recommendations. If you want to minimize the appearance of joists through the spaces between boards, paint the top of your joists black.

* use only dome-head nails from “coil-nail” gun. Pre-drill and hand nail when within 50mm of end of board. In all cases, when screwing down do not overdrive screws. Fix with low to medium torque. Do not punch nail-heads under surface of board. Fixing too close to the end of the board will cause splitting. DO NOT fix within 15mm of end of board.

Following our easy-care tips will ensure that your cladding looks fresh and attractive for years to come.

NORMAL CARE Once COEN decking is installed, periodic cleaning is necessary to keep it looking great. For dirt, dust and other residue, simply brush with a soft broom. If necessary, wash the decking down in the direction of the grain with a garden hose or a pressure washer, no more than 1,500 psi.

DECKING CARE & MAINTENANCE

PROBLEM SOLUTION

Mould and Mildew Clean away leaves and debris that promote mould growth. Ideally, you should clean the dirt off your walls before mildew starts, because the dirt is what feeds the mould. If mould/mildew appears, a deck washing product and a detergent can be used. Never mix any other cleaners with the deck washing product. Vinegar can be used to kill the mould.

Rust stains/stubborn spots Use a cleaning product containing oxalic or phosphoric acid base to lighten or remove the rust or dirt. Product may need to sit on stain 10-15 minutes.

Ice and snow If you reside in a cold weather climate and would like to avoid accumulating snow/ice on your COEN deck, use calcium chloride or safety rock salt to melt it. Remove the ice and snow with a plastic or wood shovel as it begins to melt.

Oil and Grease Stains As soon as the spill has occurred, use hot water and dishwashing detergent, to remove the stain. Be sure to thoroughly rinse the detergent off the deck with hot water. If need be, use a light stainless steel scourer

Berries and Wine Stains Mix bleach into hot water according to the bleach-packaging label. Scrub the stain lightly and rinse thoroughly. The stain may not disappear entirely.

Ink Stains Inks may be permanent. However, scrubbing with hot soapy water may lighten the stain. Rinse thoroughly.

Note: Please note that some cleaners can lighten the colour of your decking, so always test any cleaner on a small portion of before cleaning the entire surface.

ADDITIONAL TIPS ∙ Remove food, spills and other debris and clean immediately to minimize the possibility of staining.

∙ Never apply harsh solvents such as acetone, gasoline, benzene, carbon tetrachloride or paint thinner to your deck.

∙ Never mix two or more cleaning agents when cleaning your decking.

∙ Keep the area around your decking clean and well ventilated.
