Dulux Avista High Solids Epoxy Part A Resin 6L — Heavy-Duty Internal Floor Coating

The Dulux Avista High Solids Epoxy Part A Resin is the resin component of a premium two-part, solvent-based high-solids epoxy system engineered for heavy-duty internal concrete floors. When combined with the High Solids Epoxy Part B Hardener (4L, sold separately) in the specified ratio, it produces a low-viscosity, self-smoothing coating that cures to exceptional hardness with outstanding chemical and abrasion resistance.

Unlike the waterbased epoxy alternative, this high-solids system delivers a thicker film build, faster cure, and superior resistance to aggressive chemicals including sulphuric acid (30%), hydrochloric acid, ammonia (20%), toluene, kerosene, and used sump oil — making it the professional choice for commercial kitchens, industrial workshops, laboratories, and heavy-traffic retail environments.

Important: This is Part A of a two-part system. You must also purchase Dulux Avista High Solids Epoxy Part B Hardener (4L). Mix ratio is 1000 mL Part A to 650 mL Part B by volume. Pot life is approximately 25 minutes at 25 °C — work quickly.

Key Features & Benefits

• High Solids Formulation: Greater film build per coat for superior durability and chemical resistance compared to standard epoxies.
• Exceptional Chemical Resistance: Withstands sulphuric acid (30%), hydrochloric acid, ammonia, toluene, kerosene, petrol, and more.
• Self-Smoothing: Low viscosity flows to a seamless, professional finish — ideal for showrooms and commercial floors.
• Fast Cure: Dust free in ~8 hours; recoat in 10–12 hours; full cure in 10–12 hours at 20 °C.
• Low VOC: 50 g/L when tinted; 64 g/L untinted.
• Excellent Coverage: Approximately 10 m² per litre — a 10L mixed kit covers up to 100 m².

Application Guidance

Surface Preparation: Concrete must be clean, dry, and mechanically prepared (grind or shot blast). Remove all laitance, oil, grease, and existing coatings.

Mixing: Add Part B to Part A in the correct ratio. Mix thoroughly for 2–3 minutes. Pot life is only 25 minutes — mix small batches and apply immediately. Use a two-person team for efficient application.

Application: Pour onto the floor, spread with a squeegee or notched trowel, and back-roll with a short-nap roller. Apply at 10 °C – 35 °C. Clean tools with solvent immediately after use.

Frequently Asked Questions

1. What makes this “high solids” compared to standard epoxy?

High solids epoxy contains a higher percentage of solid resin material and less solvent — meaning more of what you apply stays on the floor as protective coating rather than evaporating into the air. This translates to a thicker film build per coat, better chemical resistance, and fewer coats needed to achieve the desired thickness. The trade-off is a shorter pot life (25 minutes vs 2–3 hours for waterbased epoxy).

2. Can I use this in my home garage?

Yes — this is an excellent choice for residential garages, particularly if you work on vehicles and want resistance to oil, petrol, and chemical spills. However, be aware of the short 25-minute pot life — you need to work quickly and mix small batches. For first-time DIY epoxy users, the waterbased epoxy (longer pot life) may be more forgiving.

3. How does the mix ratio work in practice?

The kit is supplied as a 6L Part A Resin and a 4L Part B Hardener — designed to be mixed together in full. If mixing smaller batches, the ratio is 1000 mL Part A to 650 mL Part B by volume. Accurate measurement is essential — use graduated mixing containers and follow the ratio precisely. An incorrect ratio will result in incomplete curing.

4. Is this product suitable for exterior use?

No. Like all epoxy systems in the Dulux Avista range, this is formulated for internal use only. It is not UV stable and will degrade under direct sunlight. For exterior two-part systems, choose Dulux Avista 2 Pack Urethane or Polyaspartic Sealer.

5. What safety precautions are needed?

Although VOC content is low (50–64 g/L), this is still a chemical curing system. Work in a well-ventilated area. Wear solvent-resistant gloves, safety glasses, and appropriate respiratory protection. Avoid skin contact — epoxy resins can cause sensitisation with repeated exposure. Keep away from food preparation areas until fully cured.

6. Can I apply multiple coats?

Yes — recoat within 10–12 hours. If you wait longer than 24 hours, the surface may need light sanding to provide a mechanical key for the next coat. For maximum chemical resistance and hydrostatic pressure resistance, three coats achieving 300 µm dry film thickness are recommended.
