Questions & Answers on TECHWOODN
1. What is Colormix Woodgrain ?
Colormix Woodgrain is a color mixture product manufactured by Techwoodn company and designed to provide
simulated woodgrain effects in WPC building products.
Since Woodgrain masterbatches are added directly into the product formulation, they appear more natural, can
come in more colors, and are more enduring than other woodgrain alternatives.
2.How many Colormix Woodgrain are available?
We do have some standard colors available, CG04M02-Butternut, CG04M12-Birch,
CY29M01-Nut brown. Please watch our Colormix Woodgrain option.
3.Is COLORMIX WOODGRAIN weatherable? Is it impact resistant?
Yes on both counts. Techwoodn's decades of accelerated and outdoor weathering experience enables us to formulate highly
weatherable custom concentrates. Similarly, our expertise in analytical and physical testing helps us create an Colormix
Woodgrain formula that offers the right balance between impact performance and cost.
4.How many streak type of Colormix Woodgrain ?
Movement – multi-colored, multi- directional streaks thatclosely mimic those found in nature. Also referred to
as scribbling or chatter.
Smear – a wide, distinct streak or smudge, which is similar in appearance to a knot, particularly when viewed
from a distance.
5.What is TECHWOODN?
TECHWOODN is a product made essentially from a mixture of ground sustainable wood waste and plastic (we actually use
recycled plastic milk bottles). TECHWOODN products contain no Formaldehydes .
6.Is TECHWOODN moisture resistant?
TECHWOODN has excellent moisture resistance, however it should be noted that TECHWOODN is not designed to "live in
moisture" - this will eventually cause swelling, and affect physical properties.
7.Does TECHWOODN need ventilation?
Yes, like timber, it is important to provide adequate ventilation to ensure TECHWOODN 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.
8.Will it warp?
TECHWOODN decking will not warp provided it is used and fixed in accordance with fixing instructions. TECHWOODN mini
board can in some circumstances, show slight deflection between uprights.
9.Does it splinter?
The composition of TECHWOODN products means that they will not splinter. This makes them ideal for small children.
10.How do I fix TECHWOODN?
Whilst TECHWOODN has many fixing similarities to natural timber, there are a few subtle differences that must be observed.
Please check Installation Guide on our website.
11.Does TECHWOODN fade?
Yes, TECHWOODN undergoes some fading when exposed to the elements. TECHWOODN 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.
12.Is it UV Protected?
Yes TECHWOODN 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. For information on fading see above.
13.How does TECHWOODN compare with timber in terms of surface temperature?
Tests have shown TECHWOODN 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
14.Can TECHWOODN be used for joists?
No, TECHWOODN has been designed for use as decking and screening products only and cannot be classed as a "load bearing"
15.Is it scratch resistant?
No - TECHWOODN can show scuffs and scratches, especially when new, and especially 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 TECHWOODN 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
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.
16.How does TECHWOODN perform when exposed to a fire?
TECHWOODN will burn like most timbers. It has been tested by the CSIRO for ignitability, flame propagation etc and found to be of a performance somewhere between softwood and hardwood. TECHWOODN is not suitable to be used in bush fire areas
17.Is TECHWOODN slippery?
TECHWOODN decking has very similar non-slip ratings to painted or coated timber decking products.
18.Is TECHWOODN suitable for use around swimming pools?
Yes - TECHWOODN 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.
19.Can TECHWOODN be used by the sea?
TECHWOODN is ideal in a marine environment, being unaffected by the salt air.
20.How can I clean and maintain TECHWOODN?
TECHWOODN 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.
21.Can water stain marks appear on TECHWOODN?
Yes, water stain marks can show on TECHWOODN boards. 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 fibres
at the surface of the TECHWOODN. 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 TECHWOODN 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.
22.Is TECHWOODN mould resistant?
As TECHWOODN has a wood-fibre base, mould and mildew can grow on the deck in some circumstances and environments,
or if it "sweats" under the plastic cover (especially in rain) before installation. Failure to keep packs dry in storage can lead to
the growth of mould spores on boards. Clean as per directions under "Care & Maintenance" on our web site.
23.What joist span do I use?
Some TECHWOODN products have different joist spans to similar timber products. Please check Fixing & Technical section for
instructions for relevant products on our website.
24.Why does TECHWOODN specify a bigger side by side gap than timber?
Timber boards will often shrink slightly in width once laid, however TECHWOODN wood fibres have extremely low moisture
content. After laying, the surface fibres will "normalise" with moisture and the boards will swell slightly. It is critical that the
side by side minimum gapping specified (
25.What are the standard colours and sizes?
TECHWOODN comes in a wide range of colours and sizes for residential and commercial applications. Check our web site for more
Please note colours may vary from batch to batch, however different batches of the same colour will weather to within a
commercially acceptable tolerance.
26.Are there special tools required for working with TECHWOODN?
With TECHWOODN you can use standard power saws and drills. As with using any power tools, adequate personal protective
equipment should be used when cutting or drilling TECHWOODN. The TECHWOODN "sawdust", is a coarse, heavy sawdust
that doesn’t tend to "float" in the air. This makes it very safe for handling.
27.How should TECHWOODN be stored and handled?
Whether at the timber merchant premises or at your own house awaiting installation, TECHWOODN packs should be stored in a
dry, flat area under roof and off the ground. Loose boards should be stored on its edge in a dry, flat area under roof and off the
ground. Failure to keep packs dry in storage can lead to the growth of mould spores on boards. When moving product around,
TECHWOODN should be carried on its edge.
28.Is TECHWOODN guaranteed?
TECHWOODN offers a limited 20-year solid boards and 15-year hollow boards warranty. Please visit our warranty information
page on the website.
All product performance claims are based on TECHWOODN products being used as recommended and installed in accordance with
TECHWOODN’s minimum fixing specifications.
29. Is TECHWOODN stain resistant?
Yes,we spray TECHWOODN WPC-CLEANER on the board polluted with tea, coffee,milk,lard and soybean oil, using the rag and
water to clean the stain. If stain are tea,coffee or milk, just need one time to clean, while stain are lard or soybean oil, just need 5 to
10 times according to the extent of pollution.
TECHWOODN WPC-CLEANER is specially used for cleaning stain on WPC.
