This standard outlines the recommended schedules for applying opaque and transparent finishes (paints, varnishes, polishes) to wood and wood-based materials. It specifies the sequence, number, and types of coats required for various exterior and interior applications to ensure durability and aesthetic quality.

Practical Notes
Wood must be properly seasoned to the correct moisture content (IS 287) prior to finishing to avoid blistering or flaking.
End grains of timber absorb more moisture and paint, requiring thorough sealing and priming.
Exterior transparent finishes degrade faster than opaque paints and require more frequent maintenance.
