Nov 14, 2013 . Quarter-sawing produces more waste than plain sawing, resulting in higher costs, but quarter-sawn lumber is more resistant to warping with changes in moisture content, and much more stable. In addition, it accepts stains better and more uniformly than plain-sawn lumber and is less prone to checking
deck. The surface material and thickness should be based on the expected weight and density of traffic. A thicker or more abrasion-resistant surface is required . Full- width asphalt or chip-seal surfaces drain water and protect the deck from moisture. Lumber, steel, and aggregate surfaces tend to trap moisture and increase..
Answer: Leaching of tannin commonly occurs if merbau is exposed to rain without a coating, or with a coating that allows moisture to penetrate. .

Factors affecting moisture content determination with resistance. Apart from moisture content, a variety of other factors affect the wood resistance and consequently also moisture content measurements. Vermaas (1975b) divided these factors into two categories; wood variables and experimental variables. Wood variables
Wood strips on the external layers are aligned to the panel's strength axis, while internal layers are perpendicular. The number of layers placed is determined partly by the thickness of the panel but is limited by the equipment installed at the manufacturing site. Individual layers can also vary in thickness to give different..
