Polyurethane sprayers may require special coatings and construction parameters when working with certain specialized types of wood. The following are some common types of specialty woods:
Higher Density Hardwoods: Certain hardwood species, such as oak and walnut, have high densities and hard surfaces. When treating these woods, it may be necessary to choose a more abrasion-resistant polyurethane coating to provide better scratch resistance and durability.
Woods with a high content of natural oils and fats: Some woods, such as certain species of pine and eucalyptus, contain high levels of natural oils and fats. These oils and fats may affect the adhesion and curing of the coating. When treating these woods, special primers or pre-treatments may be required to promote adhesion and curing of the paint to the wood surface.
COMPOSITE LUMBER: Composite lumber is a panel made up of multiple layers of wood and glued together. When treating composite lumber, it may be necessary to select a suitable polyurethane coating to ensure bonding and compatibility between the coating and the layers.
COMPRESSED WOOD: Compressed wood is made by compressing wood at high temperatures and pressures. Due to the structural changes in the wood during compression, it may be necessary to select a suitable polyurethane coating and application parameters to ensure that the coating will adequately penetrate and adhere to the surface of the compressed wood.
For specific types of wood, it is recommended that a coating supplier or professional be consulted for wood-specific advice and guidance prior to application with a polyurethane sprayer. They can provide appropriate coating selection and application parameters based on the characteristics of the wood and project requirements.
