Putty: A knead-like preparation that is applied with a scraper and usually hardened by exposure to air.
Rigid filling: A viscous slurry usually filled with a scraper in the deep recesses of the substrate that hardens thoroughly when dried.It should not be confused with glass putty, which is different from the consistency of glass putty and its hardening is much slower.
Scraping putty: A filler applied with a filler blade as opposed to a brush.
Texture bulges: Improper bulges of wood fibers caused by the absorption of water or water-bearing substances by wood structures.
Wood grain bulge: The bulge of the harder part of a wood grain when the softer part of the wood grain is contracted or eroded.
Resinous wood: Resinous wood (often called softwood).The resin has a high solubility to many paints (even if the paint is partially dried), and it often penetrates the paint film coated on such wood.
Rust grade: Describes the grade of corrosion on the surface of steel products before cleaning.The surface can be polished (with sandpaper) without being painted: A polishing process used to smooth the painted surface before applying the next coating.
Fine grinding: A grinding process in which a dry coating is lightly ground with fine sandpaper before the coating is applied.
Sealant: An organic material that provides a flexible, impermeable separation layer between two surfaces.
Powder galvanizing: Hot-dip galvanizing of zinc powder: A method of galvanizing by heating iron parts in close contact with zinc powder for several hours

( Swedish standard) for corrosion grade and cleanliness grade of steel surface after treatment: used to grade the condition of steel substrate before painting.The classification includes the degree of rust before pretreatment, the type of pretreatment, and the degree of rust, scale, and other undesirable residue after pretreatment, but the hue will vary depending on the type of particles used in the abrasive spray cleaning process.
