Specification points

Description

Joists amargoso, mandioqueira and kapur belong to hard and tropical woods with natural weather resistance. These wood species originating from South America and Indonesia are characterized by good stability. The color of these woods is initially light brown to golden red with various shades of banding, within a few days to weeks in the sun the wood changes color to a dark brown red and natural weathering occurs over time.

Color and weathering

Wood is a natural material with a natural range of color tones. Color differences are characteristic for wood and allowed. Due to UV radiation, climate and humidity, wood weatheres and changes its original color. With a dry environment, it changes to a shade of gray, and exposure to moisture or dirt will cause blackening and discoloration to a dark shade. The time and degree of weathering depends on the method of treatment, location, local conditions, roofing, exposure of the wood to the weather and other influences on the wood.

Features

Medium degree of shrinkage, medium degree of curvature, good stability, surface chipping, it is recommended to regrind the surface after installation to reach smooth surface. It is reccomended to pre-drill holes for screws to prevent splitting and cracking. Wood that is exposed to outdoor climatic influences changes in volume, dries out or grows according to climate change. There may be slight differences in width for individual boards, due to the different expansion of the wood during moisture balance between radial and tangential growth of the wood. In wood that is exposed to outdoor climatic influences, cracks, deflection of so-called troughs, torsion, cracks and fissures can occur, especially at the ends of the boards due to drying, changing depending on relative humidity or changes in climatic conditions, small holes for wood-destroying insects. If you want to restore the original color of the wood, use a professional Saicos dehumidifier (new window) according to the technical sheet. Then treat with a suitable protective oil paint. Use the stainless steel screws or fasteners only. Avoid contact with corrosive metals objects which makes hardly removable blue-black stains on the wood.

Natural oils contend

Most of tropical woods contains natural oils which may flush out from the wood during a certain period when wood is exposed to weather conditions as rain or high humidity in the form of a brown liquid. Avoid contact with walls, plaster, bricks and other surounding which can be stained. Secure rainwater pipe or sewer system in the event that the installation is made in balconies.

Wood storage

Before and during installation make sure that wood is not exposed to direct sunlight, rain, snow or other weather conditions. Keep wood covered under the foil or store it under the roof with relative humidity similar to outdoor conditions. Place the wood on stickers to allow air ventilation and keep wood out of moist and mold formation. Follow these storage instructions to prevent wood against twisting, bowing or other deformations which may apear during incorrect storage.

Care and maintenance

Clean your deck regulary, keep it out of dirt, soil, sediments and pollen. This prevents the penetration of dirt macropores into the wood. The black dirt stains can occure under objects like umbrellas stands, flower pots, bowls, mats and other where water and hight moisture can stand without proper air ventilation. Therefore carry these objects time to time and ensure natural drying and ventilation. This helps to avoid creating of dark spots on the wood.
