EVEREST^®

Test Method:
Paints are applied to black charts. After drying for seven days, the charts are placed in an abrasion testing machine and stopped at the indicated cycle. Complete deterioration occurs when a full line of black background is exposed.

Test Method:
Paints are applied to test charts with a special multi-notch applicator (a drawdown blade with a series of notches of successively higher clearance). The charts are immediately hung vertically with the drawdown stripes horizontal, similar to rungs on a ladder, with the thinnest stripe at the top. After drying in this position, the drawdown is examined and rated for sagging (top stripe=4 mils, bottom stripe=24 mils, each stripe from top to bottom represents 2 mil increase in film thickness).

Test Method:
Paints are applied to white charts and allowed to dry for 24 hours. The charts are then folded over each other. A weight is then placed on them to force the painted surfaces together. After 24 hours, the face-to-face charts are pulled apart to see if the dried paint stuck together.

Test Method:
A 4´x 4´ drywall board is primed with a white acrylic primer. After allowing the primer to dry for 24 hours, varied shades of painted black to gray stripes are applied to the primed drywall (evenly spaced). After 24 hours, the first coat is applied to the test boards by brush (on the edges) and roller (across the center). After 1 hour dry time, the second coat is applied by roller (across the center) and the results are evaluated.
