What is WPC?
WPC is a product made essentially from a mixture of ground sustainable wood waste and plastic (we actually use recycled plastic milk bottles). WPC products contain no Formaldehydes
Does WPC need ventilation?
Yes, like timber, it is important to provide adequate ventilation to ensure WPC is able to dry out after being wet. For this reason it is very important to pay attention to clearance on butt joins (end to end), spacing between boards (side by side), and minimum ground clearances. Lack of ventilation can cause the product to swell over time. Check product fixing instructions for information on ventilation requirements. Boxing in the deck will reduce cross flow ventilation and therefore should be avoided.
Will it warp?
WPC decking will not warp provided it is used and fixed in accordance with fixing instructions. WPC mini board can in some circumstances, show slight deflection between uprights.
Does it splinter?
The composition of WPC products means that they will not splinter. This makes them ideal for small children.
How do I fix WPC?
Whilst WPC has many fixing similarities to natural timber, thereare a few subtle differences that must be observed. Please check Fixing & Technical on our website.
Does WPC fade?
Yes, WPC undergoes some fading when exposed to the elements. WPC generally comes in "sanded" or "brushed" options for each colour. The "sanded" colour will fade approximately half way between its original colour and that of the "brushed" version. This will primarily happen during the first couple of months. Check our web site for indicative colour differences under "Care & Maintenance". The brushed surface shows minimal fade.
Is it UV Protected?
Yes WPC products are highly protected against UV radiation Please note however UV stabilisation is of the plastic component of the product and does not have a great affect on the fading characteristics.
How does WPC compare with timber in terms of surface temperature?
Tests have shown WPC has a similar surface temperature to timber of similar colours and finishes. Please note because Black Bean and Jarrah are darker colours, they can get quite hot under foot, especially when new (similar to a dark painted timber decking board).
Can WPC be used for joists?
No, WPC has been designed for use as decking and fencing products only and cannot be classed as a "load bearing" product.
Is it scratch resistant?
No - wpc can show scuffs and scratches, especially when new, andespecially on the "sanded surface". By rubbing on light decking oil with a clean rag the marks will be less noticeable. Exposure to the weather will see the board fade to its natural colour, thus hiding scuff and scratch marks. It is strongly recommended that all furniture on a WPC deck has protective feet e.g. rubber stoppers applied to the legs to help prevent scuffing or scratching of the deck surface. See our web site for further details.
Important - the brushed surface does not easily show scuffs and scratches. This is recommended if the product is intended for use under 100% shade/cover. The brushed surface can be wire brushed. The area you brush will quickly fade out and hide your repair.
How does wpc perform when exposed to a fire?
WPC will not burn like the timber, because there is fire retardant, the burn can be last 1.5 hs long.
Is wpc decking slippery?
WPC decking has very similar non-slip ratings to painted or coated timber decking products.
Are wpc deckings, wpc fencing, and wpc chairs suitable for use around swimming pools?
Yes – WPC material is an ideal decking to be used in a pool and spa environment. Also, as there is no likelihood of splinters occurring, it protects your feet.
Can WPC materials be used by the sea?
WPC materials are ideal in a marine environment, being unaffected by the salt air.
How can I clean and maintain wpc materials?
WPC is relatively maintenance free, however, regular cleaning is important in keeping the deck to look great. Sweeping and cleaning with normal household cleaners is usually adequate to keep your deck looking great. "Sugar soap", mixed with water works particularly well. Stubborn (usually oil-based) stains can be difficult to remove - we find that water-diluted degreaser works well - scrub in and wash off after a few minutes. Periodic cleaning of expansion joints is also recommended. Refer to “Care & Maintenance” on our web site for more detail. Tests have shown it is possible to remove graffiti paint by using paint stripper.
Can water stain marks appear on the wood plastic composite materials?
Yes, water stain marks can show on the wpc materials surface. There are two types of water stains; both of which will generally disappear with exposure to a reasonable soaking of rain and general weathering.
a) Water stains from wood tannins will occur in the early life of your deck as the natural tannins come out of the wood fibers at the surface of the wpc materials. This will happen in the early weeks of your deck, and will depend on how exposed to the elements your deck is before the weathering process is complete.
b) Water stains from water pooling or dripping can happen with wpc just like it can with many other materials/surfaces such as timber flooring, glass, laminated tables etc. The visibility of the stain will be governed by factors such as how dirty the deck is and how quickly the water dries from the water pooling. Clean as mentioned above.
