Dulux Avista Slip Resistant Additive Crushed Glass 5KG — Safety for Sealed Concrete

The Dulux Avista Slip Resistant Additive — Crushed Glass is a clear, granulated anti-slip additive designed to be mixed into or broadcast onto the final coat of Dulux Avista concrete sealers and epoxy coatings. When added to the sealer, the transparent glass particles create a micro-textured surface that significantly improves slip resistance without compromising the clarity, colour, or sheen of the finished coating.

This 5-kilogram container provides sufficient additive to treat approximately 100–150 m² of sealed concrete — making it an economical safety solution for driveways, pool surrounds, alfresco areas, and any sealed concrete surface where wet-condition slip resistance is a priority. The crushed glass particles are chemically inert, UV stable, and will not discolour or degrade over time.

Key Features

• Clear Glass Particles: Invisible in the sealer — does not affect colour, clarity, or finish appearance.
• Excellent Coverage: One 5KG container treats 100–150 m².
• Chemically Inert: Will not react with sealers, epoxies, or urethanes.
• Particle Size 0.45–0.68 mm: Coarse enough for grip, fine enough for a comfortable barefoot surface.
• Interior & Exterior: Suitable for all sealed concrete applications.
• Broad Compatibility: Works with all Dulux Avista sealers and epoxies.

Application

Mix-In Method: Add the crushed glass directly to the final coat of sealer and stir thoroughly. Apply as normal. The glass particles will be locked into the sealer film as it cures, creating a permanently textured surface.

Broadcast Method: Apply the final coat of sealer, then broadcast the crushed glass evenly over the wet surface using a hand spreader. Once the sealer has cured, any loose particles can be swept or vacuumed away.

Dosage: Adjust the amount based on the level of grip required — more additive for steeper slopes and wet areas; less for surfaces where a subtle texture is preferred.

Frequently Asked Questions

1. Will the crushed glass make my sealed concrete look cloudy or rough?

No. The glass particles are clear and transparent — they do not affect the colour or clarity of the sealer. The surface will have a very fine texture underfoot but will look identical to an untextured sealed surface. The additive is undetectable visually.

2. Can I use this with any brand of concrete sealer?

It is formulated for Dulux Avista sealers and epoxies. Whilst it is chemically compatible with most acrylic and epoxy coatings, always test a small area first when using with non-Avista products to confirm compatibility and appearance.

3. How much should I add for a pool surround?

For pool surrounds and other frequently wet, barefoot areas, use the higher dosage rate (closer to 5 kg per 100 m²) for maximum grip. The surface should feel noticeably textured under a wet bare foot. Test a small patch first to ensure the texture is comfortable — the goal is safety without discomfort.

4. Is the crushed glass better than the powder additive?

The crushed glass provides a coarser, more pronounced texture suitable for sloped driveways, pool surrounds, and high-traffic commercial areas. The powder additive (also available from Dulux Avista) provides a finer texture better suited to interior floors and areas where a smoother finish is desired. Choose based on the level of slip resistance required.

5. Can I add this to a coloured or tinted sealer?

Yes — the clear glass particles are compatible with tinted and coloured sealers and will not alter the colour.
