Mixing pigments for the purpose of creating realistic paintings with diverse color gamuts is known to have been practiced at least since Ancient Greece.The identity of a/the set of minimal pigments to mix diverse gamuts has long been the subject of speculation by theorists whose claims have changed over time, for example Pliny's white, black, one or another red, and "sil", which might have ...
The base coat is applied after the primer coat. This coat contains the visual properties of color and effects, and is usually the one referred to as the paint. Base coat used in automotive applications is commonly divided into three categories: solid, metallic, and pearlescent pigments. Solid paints have no sparkle effects except the color ...
Plaster veneer may also be applied to ordinary drywall, or over existing walls, but this requires "gluing" the existing wall surface by painting on a special adhesive compound, and then applying a thin layer of "base coat" plaster. After the blueboard or base coat covers the interior of a room, the finishing plaster is mixed in batches ...
Most common cross-linkers are solid epoxy resins in so-called hybrid powders in mixing ratios of 50/50, 60/40 and 70/30 (polyester resin/ epoxy resin) for indoor applications and triglycidyl isocyanurate (TGIC) in a ratio of 93/7 and β-hydroxy alkylamide (HAA) hardener in 95/5 ratio for outdoor applications.
The first method is generally used where quality of finish is at a premium. The second method is quicker but can be several millimetres out of plumb. The second coat can be a slightly weaker mix 5/1/1, or the same as the base coat with maybe a water- proofer in the mix added to the water to minimize efflorescence (rising of salts).
Given that having a car subsequently resprayed in a metallic color is no more expensive than for a solid color, many consider the price premium for metallic paint as a way to boost the base price of a luxury car. Japanese luxury marques and many mass market brands usually do not charge extra for metallic paint. [citation needed]

Sometimes, the two parts are of equal volume and referred to as 1:1 but not always, as 2:1, 3:1, 4:1 and even 5:1 mixing ratios are commercially available. The individual components are usually referred to as Part A and Part B. All two-part epoxies have a pot-life or working time during which the mixed material can be used.
