Technical Specifications

Application Guidelines

New Surfaces

• Clean and ensure the surface is dry; remove efflorescence with Nutech Thinners if needed 

• First coat (50% diluted): Apply at 3–5 m²/L using a soft bristle broom, roller, or spray.

• Second coat (neat): Same coverage rate, applied similarly to ensure deep gloss and protection 

Existing Surfaces

• Clean thoroughly; use acid etching for uncured concrete, degreaser for sealed surfaces. Remove incompatible sealers as recommended 

• Abrade old finishes if required; test a small area before sealing 

Hot Weather Note

• Add ~2 L of Nutech Thinners per 20 L to avoid bubbling on hot days

Frequently Asked Questions

1. What surfaces is AGRESEAL suitable for?

AGRESEAL Concrete Sealer is suitable for a wide range of exterior concrete surfaces including driveways, pathways, patios, exposed aggregate, stamped concrete, and concrete pavers. It provides a durable, clear protective coating that enhances the natural appearance of concrete.

2. How does AGRESEAL compare to Dulux Avista sealers?

AGRESEAL is a high-quality alternative concrete sealer offering excellent protection at a competitive price point. It provides reliable UV resistance, water repellency, and surface durability suitable for Australian conditions. For specific performance comparisons, speak to our team about your project requirements.

3. What is the coverage per 20L pail?

Coverage varies by surface porosity — typically 3–5 m² per litre, giving approximately 60–100 m² per 20L pail per coat. Two coats are recommended for optimal protection.

4. How long before I can drive on the sealed surface?

Allow a minimum of 5 days for full cure before vehicle traffic. Foot traffic can typically resume after 24 hours. Cooler temperatures may extend these times.

5. Do I need to strip the old sealer before applying AGRESEAL?

If the existing sealer is sound and well-adhered, a thorough clean and test patch may be sufficient. If the old sealer is peeling, flaking, or incompatible, it should be stripped before applying AGRESEAL for best adhesion and finish.

6. Can AGRESEAL be used indoors?

AGRESEAL is formulated for exterior use. For interior concrete sealing, consider a low-VOC water-based alternative suitable for enclosed spaces.

7. Is AGRESEAL UV-resistant?

Yes — AGRESEAL is formulated with UV inhibitors to resist yellowing and degradation under Australian sunlight.
