Dulux Avista Concrete Sealer Tintable Base 19L — Solvent-Based Coloured Concrete Protection

The Dulux Avista Concrete Sealer Tintable Base is a high-performance solvent-based sealer designed to be custom-tinted with Dulux Avista Sealer Colour Tints, delivering a rich, semi-gloss coloured finish to exterior decorative concrete. This 19-litre base offers superior penetration, film hardness, and UV durability compared to water-based alternatives — making it the preferred choice for driveways, pathways, and outdoor living areas where colour depth and longevity are paramount.

Formulated for Australian conditions, this tintable base provides excellent coverage of 3–5 m² per litre and requires no primer on most exterior concrete surfaces. When paired with a Dulux Avista Sealer Colour Tint (1L), it creates a durable, UV-resistant coloured coating that enhances and protects stamped, stencilled, coloured, and plain concrete. A slip-reducing additive can be incorporated for safety on inclined or wet surfaces.

Key Features & Benefits

• Custom Tintable: Mix with Dulux Avista Sealer Colour Tint (1L) to create a bespoke coloured sealer — choose from an extensive colour range to complement your home.
• Semi-Gloss Finish: Delivers a vibrant, wet-look sheen that enhances colour depth and makes decorative concrete patterns stand out.
• Solvent-Based Durability: Superior penetration, film hardness, and UV resistance compared to water-based sealers — built to last in harsh Australian conditions.
• No Primer Required: Can be applied directly to clean, prepared concrete on most exterior surfaces, saving time and material costs.
• Chemical & Stain Resistant: Excellent resistance to engine oil, fuel, salt, chlorine, alkali, and acid once fully cured.
• Slip Resistance Option: Compatible with Dulux Avista Slip Reducing Additive for improved grip on sloped or high-traffic areas.

Ideal Applications

• Coloured concrete driveways
• Stamped and stencilled concrete patios
• Plain concrete requiring a colour enhancement
• Concrete pavers
• Resurfaced concrete surfaces
• Commercial decorative concrete

Application Guidance

Surface Preparation: Surfaces must be clean, dry, and free from dust, dirt, oil, grease, and loose material. New concrete must be fully cured (minimum 28 days). Previously sealed surfaces should be assessed for compatibility — strip failing sealers before application.

Tinting: Add one 1L tin of Dulux Avista Sealer Colour Tint to the 19L base and mix thoroughly for 3–5 minutes to ensure uniform colour dispersion. Tint must be added before application — do not apply the base untinted.

Application: Apply by roller using a long-nap (20 mm) lambswool roller sleeve for best results on textured surfaces. Apply thin, even coats — two coats are recommended for optimal colour depth and durability.

Coverage: Approximately 3–5 m² per litre per coat (60–100 m² per 19L pail), depending on surface porosity.

Drying & Curing (at 25 °C, 50% RH):

• Recoat: 2 hours
• Rain resistance: 2 hours
• Foot traffic: 24 hours
• Vehicle traffic: 5 days

Safety: This product is highly flammable and has a high VOC content (689 g/L). Use only in well-ventilated outdoor areas. Wear an organic vapour respirator, solvent-resistant gloves, and safety eyewear. Do not apply below 8 °C or above 35 °C.

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

Frequently Asked Questions

1. How is this different from the Waterbased Tintable Sealer Base?

The key differences are in the carrier (solvent vs water), finish, and durability. This solvent-based version delivers a semi-gloss finish with deeper colour enhancement and superior film hardness — ideal for exterior surfaces that demand maximum durability. The waterbased version delivers a matt finish with lower VOCs — better suited to indoor use or where odour is a concern. Both can be tinted to a wide range of colours.

2. Do I have to tint this product, or can I use it clear?

This base is designed to be tinted with Dulux Avista Sealer Colour Tint (1L). If you require a clear, untinted sealer, consider the Dulux Avista General Purpose Sealer (Matt or Semi-Gloss) or Extended Wear Sealer, which are ready to use straight from the pail without tinting.

3. How many tins of colour tint do I need for a 19L pail?

One 1L tin of Dulux Avista Sealer Colour Tint is sufficient for a full 19L pail of tintable base. Add the entire contents of the tint tin to the base and mix thoroughly for 3–5 minutes. Do not partially tint — always tint the full pail for colour consistency.

4. Can I use this sealer on my existing sealed driveway?

Yes, provided the existing sealer is sound, well-adhered, and of a compatible type (solvent-based acrylic). Clean the surface thoroughly, test a small area for compatibility, and if the test is successful after 48 hours, proceed with the full application. If the existing sealer is peeling, flaking, or incompatible, strip it completely before applying this product.

5. How long will the colour last in full sun?

The solvent-based formulation offers very good UV resistance, and you can expect 3–5 years of colour retention under normal Australian conditions before a maintenance coat is needed. Darker, more saturated colours may show fading sooner than lighter tones. A fresh maintenance coat applied when the colour begins to look tired will restore vibrancy without the need for stripping.

6. Is a primer really not needed?

For most clean, bare exterior concrete, no primer is required. However, on very porous, dusty, or friable concrete, a priming coat of Dulux Avista Pre-Sealer can improve film build and colour uniformity. For recoating over existing sealers, the Dulux Avista Sealed Surface Primer is recommended to ensure inter-coat adhesion.

7. Can I apply this sealer around my swimming pool?

Yes, but with two important caveats: add a slip-reducing additive to the final coat for safety on wet surfaces, and be aware that concentrated pool chemicals may affect the sealer over time. The product has good resistance to chlorine (5% solution), but chemical spills should be rinsed promptly. Expect a slightly shorter service life in pool environments compared to general outdoor applications.
