PRODUCT APPLICATION (cont.) .
APPLICATION
Apply only when air, material, and surface temperatures
are between 40-80°F (4-27°C) and the relative humidity
should not be greater than 85%. Shake or mix thoroughly
before using. In most cases only one coat is necessary to
prime most surfaces. If excessive absorption occurs over
very porous substrates a second coat may be necessary.
Spot priming is recommended only under high-hiding
topcoat paints. For best results, prime entire surface
before painting. Apply with a high quality natural or
synthetic brush, roller, pad or sprayer. Follow
manufacturer’s instructions when using spray equipment.
For airless spraying, use a 0.015 to 0.017" tip at 1500 to
2000 P.S.I.

DRY TIME
In most cases Cover-Stain will dry to the touch in 30
minutes and can be recoated after 1 hour. The dry primer
film develops full adhesion in 7 days. Lower temperatures,
higher humidity and the addition of tint will prolong the dry
and cure time.
CLEAN-UP
Clean up spills and paint drips with a rag soaked in
mineral spirits or paint thinner. If spills or drips have dried,
use paint remover. Application tools may be cleaned using
paint thinner. Follow manufacturer’s directions to clean
spray equipment. Dispose of unused or unwanted product
in accordance with local laws regulating solvent-based
coatings.
