Calibrated plywood is not technically waterproof. That would mean it specifically refers to plywood, which has been sanded or smoothed to an exact thickness that results in a quality finish. Although it may be improved for resistant characteristics to water, in its form as calibrated plywood, it tends not to be waterproof unless further treatments are involved, such as the special waterproof coatings or special adhesives applied. For wet exposure applications, consider plywood that is labelled as waterproofed or treated because these will have better resistance to water damage. Waterproofing treatments can also improve the properties of the plywood.
Calibrated plywood is ideal for most applications requiring smooth surfaces because it is sanded precisely to have an even thickness. This makes it useful in high-quality finishes or furniture and where decorative purposes require smoother surfaces. Nevertheless, the effectiveness will depend on the treatment that the product will undergo. If moisture resistance is not treated, this product will most likely be damaged by water.
The term calibrated core plywood refers to the type of plywood that contains a core that is sanded or smoothed to provide an even thickness and surface. The precaution taken in the calibration process ensures that the plywood has the highest structural precision and is absolutely flat for use in applications requiring high-quality finishes on furniture, cabinetry, or decorative panels. It calibrates the board to strengthen its core while giving it an even surface for use on various projects requiring perfection and aesthetic appeal.
Calibrated plywood differs from regular plywood in its processing. While both are made from layers of wood veneer, calibrated plywood is precisely sanded to achieve a uniform thickness and smooth surface, making it ideal for high-quality finishes like furniture or cabinets. Regular plywood may have slight variations in thickness and surface quality, as it doesn’t undergo the same calibration process. Calibrated plywood is preferred for projects that require consistency and fine finishes, while regular plywood is suitable for general applications.
