Surface Preparation

The substrate must be dry and free from oil, grease, dirt, bituminous and other contaminants.

Application

SEALER CT can be brush, roller or airless spray applied. The appropriate amount of Hardener Powder is determined by the use of the GCP Mixing Guide and is dependent upon the temperature of the material, air and substrate. The material may be either used clear or pigmented with GCP pigment.

Cure

SEALER CT will dry to the touch, typically in 45-60 minutes. At this time it is ready for subsequent applications or for use.

SEALER CT is supplied in 4.8 gal pails and 48 gal drums. All material must be premixed prior to use.

Store in a cool, dry place and away from direct sunlight. Temperature should not exceed 90°F. Do not store near open flame or food. The shelf life is six months from the ship date in the unopened container.

Coverage

For BRIDGEMASTER® overlays SEALER CT is applied in one coat at an approximate coverage rate of 65-100 ft²/gal, actual consumption depending on the surface texture of the broadcast Aggregate that is selected.
