Dulux Avista Waterbased Epoxy Part A Resin 5L — Professional Internal Floor Coating

The Dulux Avista Waterbased Epoxy Part A Resin is the resin component of a premium two-part, water-based epoxy coating system designed for internal concrete floors. When combined with the Waterbased Epoxy Part B Hardener (sold separately) in a 1:1 ratio, it creates a durable, self-smoothing coating that delivers excellent adhesion, chemical resistance, and a professional-grade finish for garages, workshops, retail spaces, and residential interiors.

This water-based formulation offers the performance characteristics of traditional epoxy — toughness, chemical resistance, and seamless finish — with the added benefits of low VOC (21 g/L when tinted), minimal odour, and easy water clean-up. The system can be tinted with Dulux Avista Waterbased Colour Tints for a custom coloured floor, and can be overcoated with Dulux Avista Polyurethane Sealer for enhanced wear resistance in high-traffic areas.

Important: This is Part A of a two-part system. You must also purchase Dulux Avista Waterbased Epoxy Part B Hardener to create a working coating. The two parts are mixed 1:1 by volume immediately before application.

Key Features & Benefits

• Two-Part Epoxy System: Chemically cured for superior hardness, adhesion, and chemical resistance compared to single-pack sealers.
• Water-Based, Low VOC: Only 21 g/L VOC when tinted — safe for indoor use with minimal disruption to occupied spaces.
• Self-Smoothing: Flows out to a seamless, professional finish — ideal for garage floors, showrooms, and workshops.
• Excellent Adhesion: Bonds exceptionally well to both new and old concrete, with concrete failure mode in adhesion testing.
• Broad Chemical Resistance: Resists water, petrol, oil, 10% caustic, 10% acetic acid, 10% sulphuric acid, antifreeze, and vegetable oils.
• Tintable: Add Dulux Avista Waterbased Colour Tints for a custom coloured epoxy floor.
• Overcoatable: Can be topped with Dulux Avista Polyurethane Sealer for additional wear and UV protection.

• Track Free: 2–4 hours at 25 °C
• Recoat Time: 4 hours
• Light Traffic: 24 hours
• Full Cure: 4 days

Application Guidance

Surface Preparation: Concrete must be clean, dry, and free from laitance, oil, grease, and existing coatings. Mechanically profile (grind or shot blast) for best adhesion. Fill cracks and holes with a suitable epoxy filler before coating.

Mixing: Combine equal volumes of Part A (Resin) and Part B (Hardener). Mix thoroughly for 2–3 minutes using a mechanical mixer, scraping the sides and base of the container to ensure complete blending. Mix only what can be applied within the 2–3 hour pot life.

Application: Pour the mixed epoxy onto the floor and spread evenly using a squeegee, then back-roll with a short-nap roller for a uniform finish. For a primer coat on porous concrete, coverage is approximately 1L per 6 m². As a topcoat, coverage is approximately 1L per 6–10 m².

Clean-Up: Wash tools with water immediately after use — before the epoxy begins to cure.

Frequently Asked Questions

1. Do I need to buy Part B separately?

Yes. This listing is for Part A Resin only. You must also purchase the Dulux Avista Waterbased Epoxy Part B Hardener (5L) to create a working epoxy coating. The two parts are mixed in equal volumes (1:1) immediately before use. Neither part works alone — both are essential components of the two-part curing system.

2. Can I use this epoxy outdoors on my driveway?

No. This product is formulated for internal use only. It is not UV stable and will chalk and degrade if exposed to direct sunlight. If you need an exterior-grade two-part coating, consider the Dulux Avista 2 Pack Urethane Sealer or Polyaspartic Sealer — both of which are UV resistant and suitable for exterior applications.

3. How long before I can park my car on the epoxy floor?

Allow a minimum of 4 days for full cure before subjecting the floor to vehicle traffic. Light foot traffic can resume after 24 hours. Cooler temperatures will extend these times — if in doubt, wait longer. The surface may feel hard to the touch much sooner, but full chemical and mechanical resistance develops over several days.

4. Can I tint the epoxy to a specific colour?

Yes. The waterbased epoxy system can be tinted using Dulux Avista Waterbased Colour Tints (400ML). Add one 400ML tint tin per 8L mixed kit (4L Part A + 4L Part B). Note that tinting will slightly increase the VOC content to 21 g/L. The epoxy is not available in a clear formulation — the untinted product is white opaque.

5. What is the coverage per kit?

Coverage depends on the application:

• As a primer coat: ~1L mixed product per 6 m² (more on porous concrete)
• As a topcoat: ~1L mixed product per 6–10 m²
• A 10L mixed kit (5L Part A + 5L Part B) will cover approximately 60–100 m² as a single coat, depending on porosity.

6. Can I apply this over my old garage floor paint?

It depends. The existing coating must be well-adhered, not peeling, and chemically compatible. Old floor paints — particularly single-pack enamels — may not bond well with epoxy and could lift. The safest approach is to mechanically prepare the floor (grind or shot blast) to remove existing coatings and expose clean concrete. Always test a small area first.

7. Is this epoxy slippery when wet?

Epoxy floors can be slippery when wet — particularly in garages where water drips from vehicles. For areas where slip resistance is a concern, broadcast a fine aggregate or anti-slip additive into the wet topcoat, or add a compatible slip-resistant additive to the final coat. Consult the Dulux Avista technical data sheet for recommended slip-resistant products.
