Frequently Asked Questions

1. What is the difference between AuSeaL EC25 and EC-30?

The key difference is the solids content: EC25 has approximately 25% solids, while EC-30 has approximately 30% solids. Higher solids generally mean greater film build per coat and potentially longer service life. EC25 is an excellent mid-range option offering a balance of performance and economy.

2. What finish does EC25 provide?

AuSeaL Clear EC25 delivers a semi-gloss finish that enhances concrete colour and provides a clean, attractive sheen without being excessively glossy.

3. Can EC25 be used on stamped concrete?

Yes — AuSeaL Clear EC25 is suitable for stamped, stencilled, coloured, and plain concrete, as well as concrete pavers and exposed aggregate.

4. How many coats are needed?

Two coats are recommended for optimal protection and appearance. On very porous concrete, a third coat may be beneficial.

5. What is the drying time?

Recoat time is approximately 2 hours at 25 °C. Foot traffic after 24 hours, vehicle traffic after 5 days. Cooler temperatures extend drying times.

6. Is EC25 suitable for pool surrounds?

Yes, but add a slip-resistant additive to the final coat for safety when wet. The sealer has good chlorine resistance but chemical spills should be rinsed promptly.

7. How should I store leftover product?

Reseal the container tightly and store in a cool, dry place away from direct sunlight and ignition sources. Shelf life is approximately 24 months in unopened containers.
