Paint is a liquid that dries into a solid opaque form after it has been applied on a surface. It is usually composed of pigment, binder, solvent and additives which all contribute to its performance and application on a given surface. Paint can be used in various applications. One could be for protection as in painting buildings and structures to ward off the effects of water and sun. Paint may also serve as decoration as in applying decorative painting, and also in drawing pictures and in creating signs for information. There are many paint variations which are used in the different applications of paint.
Before the actual painting, a Primer is the preparatory coating applied to the surface of the material being painted. The application of a primer ensures that the paint will better adhere to the surface, will be more hard-wearing. It also provides additional protection for the material painted.
An Emulsion paint is the water-based paint basically used in either interior or exterior surfaces.
There are also paint without pigment utilized for protective coating such as varnish and shellac. A varnish is a see-through film principally used as wood finishing. The shellac, which is actually a resin secreted by a female lac bug to mold a cocoon has many functions: primer, sanding sealant, tannin-blocker, odor-blocker, stain, and high-gloss varnish among many others.
The wood stain provides a thin film on the surface. It has a formulation that allows its pigment to penetrate and be absorbed into the surface instead of remaining with the film. Its composition are pigment, solvent and a little amount of binder.
The lacquer is essentially a clear or colored varnish that dries up quickly as a hard and durable finish. It may range from being ultra matte to high glossed.
The paint that produces a hard and glossy finish when dry is the enamel paint which contains glass powder or tiny metal flake fragments in place of pigments found in most standard oil-based paints.
A glaze refers to the additive or paint composition that decreases the drying time of applied paint to increase its luminousness especially in Faux and art painting.
A roof coating, as the name implies, is used on roofs to protect it from UV rays due to the material’s elastic properties that allows it to be stretched and be returned to its original shape without damage.
A fingerpaint is a kind of paint applied on a surface by the use of the fingers and usually comes in pots. Adults may use it in teaching art to children.
Anti-graffiti coatings are applied on surfaces to whitewash graffiti vandal markings and could either be sacrificial or non-bonding. The first type, sacrificial, allows removal of graffiti. The material is applied on the vandalized surface and washed off with hosed water. Both graffiti and the paint will be removed, thus sacrificial. Surfaces applied with non-bonding coatings does not allow graffiti application on them.
Anti-climb paint is a type of coating that appears similar to a usual paint but is actually very slippery. A wall painted with this kind of paint is extremely hard to be climbed onto and it rubs off on to the climber.
