- Usage
GacoFlex E5691 is intended to seal and prime in a single step prior to the application of GacoFlex coating systems over concrete decks. This penetrating sealer and primer is specifically formulated for use on concrete surfaces, but may also be applied to plywood (please refer to General Instructions GW-2-3 Plywood Selection and Installation). GacoFlex E5691 meets ASTM C309 requirements for use as a concrete curing compound (water loss of 0.55kg/m²).

- Paints & Coatings
- Coverage
Up to 400 ft²per gallon (9.84 m²/L) over smooth surfaces such as plywood and lightly etched concrete. For moisture vapor mitigation application, the concrete must be shot blasted or ground to a CSP 2 where one gallon of the combined product will cover 200 ft² yielding 2.6 dry mils. On freshly poured green concrete when used as a curing compound, the coverage rate should also be approximately 200 ft² per gallon to meet the ASTM C309-11 standard for water loss.
- Consistency
The A&B components are slightly viscous independently and form a more viscous emulsion when mixed. Becomes water thin when diluted.
- Limitations
Not intended for application to glass or metal. Not intended for application to green concrete to prepare for the installation of a conventional roofing system.
