Why should you Paint







Why is painting required?

Around your home, you'll ordinarily require paint for three basic elements - walls, metal and wooden surfaces. In their lifetime, each of these will necessarily need painting because with time, their beauty and strength decreases.

Wall surfaces chip and crack, metals rust and corrode, while wooden furniture and doors get warped and scratched. Different paints have specific properties that prevent, or at least delay this. They form a protective layer around the substrate, keeping it relatively safe. Naturally, since walls are different from metals, which in turn have properties dissimilar to wood, each surface requires a different type of paint. Today, different paints have been developed, specific to each category.

Thus the main purposes of painting are:

WHAT IS PAINT?

There's more to paint than meets the eye. Physically, paint is a mixture of four important elements: Pigments, Additives, Binders and Solvents                 

Pigments

It renders color and opacity to the paint film.

Additives

This helps in holding of the paint to the surface of pigment to pigment. It alos endows the paint with special properties such as resistance to fungus, rust etc.

Binders

This holds the paint together and also bind it to the surface being painted, thus promoting durability. It gives gloss to the surface.

Solvents

This gives a paint its flowing property, enabling brushing/rolling on a surface and mixing. Depending on the solvent used, paints can be categorized as water-based (where water is the solvent), e.g. plastic emulsions and distempers or oil-based (where Thinner, a petroleum by-product is the solvent) e.g. enamels and wood finishes.

Types of Finishes

When Surface Coatings (Top coat of Paint) dry, they produce films with varying degree of sheen. The range extends from Flat or Matt finishes which have no sheen, through increasing degree of Luster to high gloss finishes.

Based on the reflectance level of the dried film of paint we can classify the finish in to following four heads:

Matt

It is the kind of finish, which has the lowest level of gloss. When the gloss on a panel painted with a Matt finish paint is measured in a glossometer at 60-degree angle, the reading is less than 5.

Egg Shell or Satin

This finish has silk like gloss, explains the name Satin finish. When the gloss on a panel painted with a Satin finish paint is measured in a glossometer at 60-degree angle, the reading is 6-20.

Semi-Gloss

This finish has more gloss than a satin finish. When the gloss on a panel painted with a Semi-Gloss finish paint is measured in a glossometer at 60-degree angle, the reading is 21-70.

Glossy

This is the finish with highest level of gloss. When the gloss on a panel painted with a Gloss finish paint is measured in a glossometer at 60-degree angle, the reading is more than 70.
