Wood Coatings

Wood coating is one of the necessary processes required by the wood-based industry for the purpose of decoration or protection. There are many types of coatings which are defined by how they are cured: evaporative, reactive or coalescing. Several techniques of coatings are available that include brushing, curtaining, dipping, flowing, spraying and 'rollering' which each has its own advantages and disadvantages. The performance of wood after coating can be determined by doing some testing such as abrasion, impact resistance, adhesion, scratch, dry heat, temperature-change and household chemicals tests. The selection of correct coatings type, proper coating technique and understanding well the properties of wood are important to produce high quality coated wood.
