A water-based primer, used primarily on wood. A primer (/ ˈ p r aɪ m ər /) or undercoat is a preparatory coating put on materials before painting.Priming ensures better adhesion of paint to the surface, increases paint durability, and provides additional protection for the material being painted.
Like paint, wallpaper requires proper surface preparation before application. Additionally wallpaper is not suitable for all areas. For example, bathroom wallpaper may deteriorate rapidly due to excessive steam (if is not sealed with a specific varnish). Proper preparation includes the repair of any defects in the drywall or plaster and the ...

Some painters had their works lined immediately after, or even before, completion. [2] The treatment was intended to mitigate mechanical damage and some nineteenth century academics considered it a necessary step before any other treatments should be enacted.

It is widely used in industrial processes to prepare surfaces for bonding, gluing, coating and painting. Plasma processing achieves this effect through a combination of reduction of metal oxides, ultra-fine surface cleaning from organic contaminants, modification of the surface topography and deposition of functional chemical groups.
