Dulux Avista Extended Wear Concrete Sealer — Maximum Durability for High-Traffic Concrete

The Dulux Avista Extended Wear Concrete Sealer is the heavy-duty option in the Dulux Avista concrete sealer range — engineered for surfaces that demand the highest level of protection against traffic, weather, and chemical exposure. This solvent-based, semi-gloss clear coating delivers a noticeably tougher film than standard sealers, making it the preferred choice for driveways, commercial entrances, and high-traffic pathways where longevity is paramount.

With excellent UV resistance, superior chemical resistance, and a robust film build of 40–80 microns dry per coat, the Extended Wear Sealer is built to outperform. It requires no primer on most surfaces, has a quick 2-hour recoat time, and provides reliable protection against oil, fuel, chlorine, salt, and the daily grind of residential and commercial use.

Key Features & Benefits

• Extended Wear Formulation: Tougher, thicker film build than standard sealers — designed to withstand higher traffic volumes and harsher conditions.
• Semi-Gloss Finish: Delivers a rich, polished appearance that enhances concrete colours and patterns whilst providing lasting protection.
• No Primer Required: Can be applied directly to clean, prepared concrete — saving time and material costs on most projects.
• Excellent Chemical Resistance: Resists alkali, salt, chlorine, mineral turpentine, and incidental fuel and oil spills once fully cured.
• Very Good UV Resistance: Protects against Australian sun exposure, helping prevent fading and degradation of the sealer and the concrete beneath.
• Quick Recoat: Recoat in just 2 hours, allowing multi-coat application in a single day.
• Versatile Substrate Compatibility: Suitable for stamped, stencilled, resurfaced, and coloured concrete, plus concrete pavers.

Ideal Applications

• Residential driveways and garage aprons
• High-traffic pathways and entrance areas
• Stamped, stencilled, and decorative concrete
• Coloured concrete patios and alfresco areas
• Commercial concrete floors (exterior)
• Concrete pavers in high-wear locations

Application Guidance

Surface Preparation: Surfaces must be thoroughly clean, dry, and free from dust, dirt, oil, grease, and loose or flaking material. New concrete must be fully cured (minimum 28 days). Previously sealed surfaces should be assessed for compatibility — a test patch is recommended. Failing or incompatible sealers must be stripped before application.

Application: Apply by roller using a solvent-resistant roller sleeve. Apply thin, even coats — heavy application can lead to blistering, extended drying, and uneven finish. Two coats are recommended for optimal durability and appearance.

Coverage: Approximately 3–6 m² per litre per coat (60–100 m² per 20L pail), depending on surface porosity and profile.

Drying & Curing (at 25 °C, 50% RH):

• Recoat: 2 hours
• Rain resistance: 2 hours
• Foot traffic: 24 hours
• Vehicle traffic: 5 days
• Full chemical cure: 28 days

Clean-Up: Clean tools and equipment with mineral turpentine or a suitable solvent immediately after use.

Safety: This product is highly flammable. Eliminate all ignition sources during application. Use in well-ventilated outdoor areas. Wear solvent-resistant gloves, safety glasses, and appropriate respiratory protection.

Why Choose Extended Wear?

If your concrete surface sees regular vehicle traffic, is fully exposed to the elements, or simply needs to look good for longer between maintenance coats, the Extended Wear Sealer is the logical upgrade from a standard general-purpose product. The increased film build and tougher resin system translate directly into longer service life — meaning fewer weekends spent resealing and more time enjoying your outdoor spaces.

Frequently Asked Questions

1. How does the Extended Wear Sealer differ from the General Purpose Sealer?

The Extended Wear Sealer is formulated with a tougher resin system and a thicker recommended film build (40–80 microns dry versus approximately 40 microns for the General Purpose range). In practical terms, this means greater resistance to abrasion, traffic wear, and chemical attack — and ultimately a longer service life. If your concrete surface experiences heavy or regular vehicle traffic, or if you simply want maximum durability, choose Extended Wear. For lighter-duty applications, the General Purpose Sealer offers excellent protection at a more economical price point.

2. Do I really not need a primer?

For most clean, bare concrete surfaces, no primer is required — the Extended Wear Sealer can be applied directly. However, on particularly porous, dusty, or friable concrete, a priming coat (such as the Dulux Avista Pre-Sealer or a thinned first coat of the sealer itself) can improve adhesion and finish. For previously sealed surfaces, ensure compatibility with a test patch and consider the Dulux Avista Sealed Surface Primer if adhesion is uncertain.

3. How long will the Extended Wear Sealer last compared to a standard sealer?

Under comparable conditions, the Extended Wear Sealer typically delivers 3–5 years of service compared to 2–4 years for a standard general-purpose sealer. The actual lifespan depends on sun exposure, traffic volume, cleaning practices, and whether the surface is covered or fully exposed. Regular maintenance — such as prompt cleaning of spills and application of a maintenance coat when water stops beading — will maximise the life of any sealer.

4. Can I use this sealer on my swimming pool surround?

Yes, with one important caveat: add a slip-resistant additive to the final coat. Pool surrounds are frequently wet and often barefoot — safety must be the priority. The Dulux Avista Slip Res Additive (Crushed Glass) can be mixed into the sealer without affecting clarity or colour. Also note that pool chemicals (particularly chlorine) will eventually affect any sealer — the Extended Wear formula has good chlorine resistance, but concentrated chemical spills should always be rinsed promptly.

5. What happens if it rains before the sealer is fully dry?

The sealer achieves rain resistance in 2 hours under ideal conditions (25 °C, 50% RH). If rain falls within this window, it can cause whitening (blushing), water spotting, and compromised adhesion. If this occurs, allow the surface to dry completely and assess the damage. Minor water spotting may resolve with time or with a light solvent wipe. Severe whitening or delamination may require stripping and reapplication. Always check the weather forecast before starting — a clear 24-hour window is ideal.

6. Can I apply this sealer in direct sunlight?

It is best to avoid application in direct, hot sunlight. When the concrete surface is hot, the sealer can dry too quickly — leading to lap marks, poor flow-out, and potential blistering as trapped solvents try to escape. Apply in the cooler parts of the day (early morning or late afternoon) and work away from the sun where possible. The ideal surface temperature range is 8 °C to 35 °C.

7. Is the Extended Wear Sealer suitable for commercial or industrial use?

Yes — this product is well suited to light commercial applications such as retail entrances, café forecourts, display areas, and office pathways. For heavy industrial applications involving forklift traffic, constant heavy loads, or exposure to aggressive chemicals, consider a two-pack epoxy or polyurethane system (such as the Dulux Avista 2 Pack Urethane or High Solids Epoxy range) which offer even greater durability and chemical resistance.
