Dulux Avista Polyaspartic Sealer Part A 10L — Fast-Cure, One-Coat Concrete Protection

The Dulux Avista Polyaspartic Sealer Part A is the resin component of a cutting-edge two-part, solvent-free polyaspartic clear gloss coating system. When combined with Polyaspartic Sealer Part B (10L, sold separately) in equal parts, it creates a single-coat sealer that cures rapidly — delivering foot-traffic-ready surfaces in just 1–2 hours and light vehicle traffic in 24 hours.

Polyaspartic technology represents the latest advancement in concrete coating chemistry. Compared to traditional epoxy and urethane systems, it offers faster cure, excellent UV stability, superior abrasion resistance, and the ability to be applied in a wider temperature range — making it the professional choice for commercial and high-end residential projects where downtime is costly.

Important: This is Part A of a two-part system. You must also purchase Dulux Avista Polyaspartic Sealer Part B (10L). Mix equal parts A and B. Pot life is approximately 40 minutes — mix only what can be applied within this time. A two-person application team is recommended.

Key Features & Benefits

• Single-Coat System: Unlike traditional sealers requiring 2–3 coats, the polyaspartic achieves full protection in one application — saving time and labour.
• Extremely Fast Cure: Walkable in 1–2 hours; light vehicle traffic in 24 hours — minimal downtime for homes and businesses.
• Solvent-Free, Low VOC: Suitable for retail, food preparation, healthcare, and educational environments where air quality is critical.
• UV, Chemical & Abrasion Resistant: Stands up to sunlight, spills, and heavy foot traffic without yellowing or degrading.
• Interior & Exterior Use: One product for all applications — from outdoor entertaining areas to indoor commercial showrooms.
• Gloss Finish: Delivers a vibrant, polished appearance that enhances decorative concrete.

Application Guidance

Surface Preparation: As with all high-performance coatings, surface preparation is critical. Concrete must be clean, dry, and properly profiled. Mechanically prepare (grind or shot blast) for best results.

Mixing: Stir Part B first, then mix equal volumes of Part A and Part B. Mix thoroughly. Pot life is only 40 minutes — mix only what a two-person crew can apply in this time (~4L per batch is recommended).

Application: Pour onto the floor, spread with a squeegee, and back-roll for a uniform finish. Work systematically — the fast cure means you cannot go back over areas that have begun to set. Apply at 20–30 °C for optimal working time.

Clean-Up: Clean tools with a suitable solvent immediately after use — once cured, the coating is highly resistant to removal.

Frequently Asked Questions

1. What makes polyaspartic technology better than traditional epoxy or urethane?

Polyaspartic coatings offer a unique combination of advantages: single-coat application (vs 2–3 coats for most systems), extremely fast cure (walkable in 1–2 hours vs 24+ hours for epoxy), solvent-free formulation (safe for sensitive environments), and excellent UV stability (unlike epoxy which chalks in sunlight). The trade-off is a short pot life (40 minutes) requiring efficient work practices and ideally a two-person team.

2. Can I really achieve full protection with just one coat?

Yes — this is one of the defining features of the polyaspartic system. The chemistry delivers a thicker film build and complete protection in a single application, unlike traditional sealers that rely on multiple thin coats to build up protection. However, coverage rate must be carefully managed — applying too thinly will compromise protection. Stick to the recommended 5–12.5 m² per litre.

3. How do I manage the 40-minute pot life on a large area?

Plan ahead. Divide the area into manageable sections. Mix small batches (~4L at a time, enough for ~20–50 m² depending on porosity). Use a two-person team: one person mixing and pouring, the other spreading and rolling. Work in cooler conditions (morning or late afternoon) to extend the pot life. Once a section begins to set, do not go back over it — plan your exit path before starting.

4. Is polyaspartic safe for food preparation areas?

Yes — the solvent-free, low-VOC formulation makes it suitable for commercial kitchens, food processing areas, and hospitality venues where air quality and chemical exposure are regulated. Once fully cured (24 hours), the coating is inert and safe for food contact surfaces.

5. Can I apply polyaspartic over an old epoxy floor?

Yes, provided the epoxy is sound, well-adhered, and properly prepared. Lightly sand the epoxy surface to provide a mechanical key, ensure it is clean and dry, and test a small area for compatibility. The polyaspartic will provide the UV stability that the epoxy beneath lacks — making it an excellent upgrade for epoxy floors near windows or in covered outdoor areas.

6. What is the difference between polyaspartic and the 2 Pack Urethane?

Both are high-performance two-part systems, but they serve different priorities. Polyaspartic is faster (1–2 hrs to foot traffic vs tack-free in 30 min–2 hrs for urethane), requires only one coat, and is solvent-free — ideal for commercial projects with tight deadlines. 2 Pack Urethane has a longer pot life (3–4 hrs vs 40 min), a higher gloss, and is better suited to projects where the applicator wants longer working time. Both are UV stable and suitable for interior and exterior use.

7. What temperature range can I apply this in?

The recommended application temperature is 20–30 °C. The short pot life is temperature-dependent — warmer conditions accelerate the cure further, whilst cooler conditions extend working time slightly. Do not apply below 10 °C or above 35 °C. In hot weather, work early in the morning and mix smaller batches to stay ahead of the cure.
