The new Natural range is a natural unprimed board which provides a unique appearance with the characteristics and look of raw, undressed timber. The Natural surface is pressed to create a woodgrain effect. Its rough deep cut pattern shows all the knots, cracks and imperfections of natural timber. When the Natural surface is oiled, the look of fresh brown timber is maintained. When allowed to weather naturally, the depth of colour will vary, subject to location and sun exposure. Weathertex is the only timber product to be covered by a 10 year warranty not to rot, split or crack.
The 300mm board contains two 15mm wide grooves. The groove begins with a sharp 5mm groove. The groove has a flat 10mm base before it is followed by another sharp 5mm rise, which meets with the Natual surface. When the following board is placed above the previous, the second groove is complete. Curved walls up to a 2.5m radius can be achieved for Selflok.
