Triton Decking Installation & Technical Details
Please see below the installation guidance below as provide by the manufacturer.
Important Installation Instructions
- Slight colour and surface differences may occur due to slight differences in raw materials or surface treatment. The deck boards will fade by approx. 10% of the colour over the first 12 month period of being installed. At the end of this period the surface colour will stabilise.
- It is advisable to place the deck boards in the required installation site for 72 hours before you start the installation for them to acclimatize. The decking should not be installed in temperatures below 5 degree's.
- We advise to use original accessories and parts from STORM to ensure warranty remains valid.
- There must be a space of at least 25mm between the ground and substructure. In case of insufficient ventilation any warranty will be invalidated. There should not be direct contact between the decking structure and the ground (grass, soil etc)
- Variations in temperatue and moisture uptake will result in expansion (about 0.3% to 0.5%).
- A strong and compacted base such as concrete is recommended.
- WPC products are not suitable for closed and moist environments such as sauna rooms etc.
Installation
- Ensure there is sufficient drainage below the deck area.
- Lay the sub frame with a slight gradient of 1% to 1.5% away from the walls, laid lengthways. Keep the sub frame set off any surrounding walls or other obstacles to allow for slight expansion.
- Keep the substructure at a maximum of 400mm centres (We recommend 350mm).
- The substructure should be fixed by expansion screws to the concrete at a distance of 300-400mm.
- To ensure each deck board has a full bearing each end, for runs lower than 5m, the subframes should overlap by a minimum of 100mm.
- If the deck boards have to be joined on the length, a second section of sub frame should be added.
WPC Product’s expansion rate is around 0.3% to 0.5% depending on different weather conditions in different places, based on this expansion rate, there must always be a gap between 2 WPC products as follows:
- The distance of at least 30mm from walls or other obstacles to allow for expansion of the deck boards.
- Allow at least a 10mm gap on butt joints.
- IMPORTANT: When fixing the starter clips or the connecting clips, we recommend pre-drilling with a 2.5mm drill bit to prevent cracking or breaking the sub frame as WPC products have a high density.
Finishing
- There must be a gap at the joint between the 2 corner covers, calculated based on the expansion rate of 0.3% - 0.5% of the length.
- The distance between the fixing screws have to be a minimum of 300cm.
- When fitting the matching angle trim you can use STORMfix, a one part solvent free hybrid adhesive with a very high initial grab and no slip properties.
Expansion
The deck area can be finished with the Angle Trim product around the perimeter, this provides a neat finish to the deck. Allow the same expansion tolerances as the decking.
Maintenance
Stains;
Water stain marks can show on composite deck boards. There are 2 main types of water stains; both of which will generally disappear with exposure to general weathering.
1. 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 composite decking. This will happen in the early week of your deck being laid, and will depend on how exposed to the elements your deck is before the weathering process is complete. This type of stain can be more prominent when new decking is exposed to direct sunlight in the first few months of its life.
2. Water stains from water pooling or dripping can happen on composite decking just like it can with many other materials/surfaces such as timber decking, glass, laminiated flooring etc. This can leave a “shoreline” effect. The visibility of the stain will be governed by factors such as how dirty the decking is and how quickly the water dries from the water pooling, clean as mentioned above.
Again, this can be exaggerated in hotter weather.
Both types of marks/stains will disappear natually over time unless, of course, you have a recurring problem that allows water to continually land on the composite decking. E.g. a drip from the gutter will continue to make marks.
Oil or cigarette stains etc can be very diffilcult to remove from the surface, avoid contact at all times.
We advise to let the composite decking weather naturally over time. However, we understand you want to be proud of your new deck once installed and if you feel the need to try and remove the marks yourself then wash with clean, hot water, this should wash away most.
Do not wash your decking whilst it is still hot from a days sunshine.
1. Pour clean, hot water on the deck and let it sit for 5-10 minutes.
2. Work in with a soft bristle brush.
3. Pressure wash (at low pressure and wide fan) or rinse down in hot water (preferred option).
4. Squeegee water off the deck with a squeegee brush.
5. Mop up any wet areas with a clean sponge mop. If water marks have been long standing they may require more hot water or repeated procedure.
IMPORTANT: Never use strong detergent or bleach based products.
Colour Difference
Sometimes you may see a colour difference in the composite decking boards, as they are produced in batches using natural products, and therefore there is no way to prevent this from happening.
