Commonly used types of paint

People have used paint for centuries as a means of adding color to the world. Paint also protects and covers houses and cars and provides markers for traffic on the streets or signs for businesses. Paint can add beauty and cover the faults of an otherwise drab artificial environment. Paint itself is a mixture of liquid and powder; the powder is the pigment that gives color to the paint and the liquid is what binds it and allows it to spread. In some paints a solvent, or thinner, is used to make the paint easier to spread. The kind of liquid and solvent used is determined by the kind of paint being made. There are many kinds of paint and they have many different uses.

Oil-based paints are thick and are commonly used as a protective barrier. Outside paints can protect houses and buildings from weather and the elements, while wall and floor paints provide color to the inside. Wall paints can be glossy, semi glossy, or flat, depending on the amount of inert pigment in the paint. The larger the amount of pigment, the flatter the paint, and the smaller the glossier. Metal protective paints are used on the metal machinery of farms and factories and on the surfaces of structures such as bridges or boats. These paints prevent the formation of rust and damage caused by corrosion from wind, water, and other variables.

Latex paints can be used indoors and outdoors much like oil-based paints, and are generally preferred due to their ease of use. Because these paints are water-based, they can be cleaned up with soap and water, however, latex wall paints are not as glossy as oil-based. Latex masonry paints are used mainly on bricks and cement and form a film that holds in the alkali on the surface.

Primers are used as the first coat on plaster and wood walls and usually have a varnish or synthetic resin base. They coat and flow into the uneven surface, filling in the tiny holes and cracks to allow the next layers of paint to be smoothed across without soaking into the wall. Enamels are used to cover inside and outside surfaces. They contain little pigment and provide a glossy sheen most commonly seen in kitchens and washrooms.

Lacquers are used to paint automobiles and are made with synthetic resins and fast evaporating solvents. Pigment is added to the solution and, after application, the paint dries quickly as the solvent evaporates. Metallic paints use aluminum or bronze powder that gives a metallic sheen when the flakes float to the surface of the paint film.

Fire-retardant and heat-resistant paints are used where there is danger of high heat or fire. Fire-retardant paints use an oil or oil resin base and have chemicals that cause it to blister and form an insulating barrier between the fire and the wall. The paint will burn but can be put out once the igniting fire is removed. Heat-resisting paints cover warm or hot surfaces such as ovens, boilers, or the cylinder heads in aircraft engines. Alkyd-resin bases are used in paints for moderately hot surfaces while silicone-resin is used for higher temperatures. Very hot surfaces use a metallic pigment mixed with varnish to evaporate and leave only the pigment bonded to the surface.

 

Interior Paint Problems & Solution


Burnishing

Increase in gloss or sheen of paint film when subjected to rubbing, scrubbing or having an object brush up against it...


Blistering

Bubbles resulting from localized loss of adhesion and lifting of the paint film from the underlying surface...
 

Blocking

Undesirable sticking together of two painted surfaces when pressed together (e.g., a door sticking to the jamb)...


Caulk Failures

Loss of caulk's initial adhesion and flexibility, causing it to crack and/or pull away from the surfaces to which it is applied...

 

Cracking - Flaking

The splitting of a dry paint film through at least one coat as a result of aging, which ultimately will lead to complete failure of the paint. In its early stages, the problem appears as hairline cracks; in its later stages, flaking occurs...

Grease on walls

Oil, grease or grime on wall surfaces. Common in kitchens and garages. Grease on the walls causes poor paint adhesion, stains, or small "pinpoint" rust spots.

Solution:

Wash the surface with detergent and warm water, apply an isolating primer such as X-Terminator alkyd, and repaint with a coat of Kitchen and Bath acrylic enamel.
