EVERTUFF™ is an extruded product which comes out with a thin shiny outer layer that is darker than the core. Any light scratching to the product can be repaired with a fine course sandpaper, however the area rubbed will lighten in colour as the outer layer is removed. Rub a lightly oil based rag into the affected area to darken, any oil is sufficient for this.
DuraComp™ products once installed can sometimes develop markings that look like water stains. This development happens as the product is adjusting to being outside. These markings will fade as the product adapts correctly to its surroundings.
For a light cleaning a soft broom or brush can be used to wipe over the product or for a more intense clean a high pressure washer can be used, ensuring a distance is kept of at least 300mm.
Scratching, oil, alcohol and cigarette stains will need to be buffed gently with either sandpaper or steel wool. Clean the surface with hot water and soap once the stain has been removed.
The width of the finishing board can be reduced as required by sawing so that it remains supported across it’s width by the joists and/or fascia board. DuraComp™ decking boards make ideal fascia boards. When used as fascia boards they should be screwed at no more than 900mm centres to an appropriate frame fixed to the sub frame.
Cosset WPC decking products can and have been installed around salt water and chlorine swimming pools. Heavily chlorinated water may cause staining of the boards. Hollow boards are not recommended.
WPC decking expands and contracts longitudinally (lengthways) due to changes in temperature (there is minimal change to the width of the boards). This is known as ‘Thermal Movement’ and products that contain plastic are especially affected.
It is very important to have an understanding of the board temperature, as boards cut at different temperatures will affect the appearance of the finished deck.
A 3600mm board will grow in length by approximately 1mm for every 10°C increase or decrease in temperature.
