Frequently Asked Questions

1. What colours are available in AuSeaL Coloured Sealer?

AuSeaL Coloured Sealer is available in a curated range of popular Australian colours. Contact Singh Roofing Supplies for the current colour card and availability.

2. Can I apply AuSeaL over an existing clear sealer?

Yes, provided the existing sealer is sound and compatible. Clean thoroughly and test a small area first. The coloured sealer will add colour on top of the existing clear finish.

3. How long will the colour last?

Under normal conditions, AuSeaL Coloured Sealer provides 3–5 years of colour retention before a maintenance coat is recommended. Darker colours in full sun may require earlier maintenance.

4. Do I need a primer?

On most clean, bare concrete, no primer is required. For very porous surfaces or over existing sealers, a primer coat may improve adhesion and colour uniformity.

5. Is AuSeaL suitable for driveways?

Yes — AuSeaL Coloured Sealer is formulated for exterior concrete including driveways, providing UV resistance and good tyre marking resistance.

6. How many coats are recommended?

Two coats are recommended for optimal colour depth, uniformity, and protection.

7. What sheen level does AuSeaL Coloured Sealer provide?

AuSeaL Coloured Sealer delivers a semi-gloss finish that enhances colour depth whilst providing a natural, attractive sheen — not overly glossy.
