The Quality Assurance Tests
An experienced person checks the color to decide if the desired shade matches the decided standard. Some part of the paint is exposed to the arc light for some time and then it is compared to the non exposed part to decide the resistance of the color to the natural elements. Then paint is applied over black and white surface. It is done to measure the paint’s hiding quality. 0.98 is considered high-quality paint so the black and white surface ratio is compared with 0.98. The gloss is measured by the amount of light is reflected off a painted surface.
As paint has more functional qualities, different tests are performed. Most important is the scratch test. A piece of tape is applied on the painted surface and then pulled off. Good paint will not come off. A machine is used to determine the scrubbability. The machine uses soapy brush and rubs the painted surface.
Another measure to see the good paint is rate settling. Good quality paint can sit for six months with no settling. So the number given to the paint is 10. Poor paint can settle faster and is rated accordingly. Paints are checked for its fire retardancy by actually burning the paint. Then the weight loss is determined. If the loss is more than 10% then the paint is not fire resistant.
The top quality paints are manufactured so it
-
Sticks better so it is less likely to peel or flake
-
Its chalk resistance is better so the chosen color looks the same
-
It resists dirt so the paint looks fresh for long time
-
It’s mildew resistance is better so the brown or black blotches do not mar the paint
