Overview

The Dulux Avista Solvent Based Rejuvenator is a specialised treatment for the whitening, milky haze and clouding that develop between clear concrete sealer layers over time. It penetrates and re-flows aged solvent-based acrylic sealers, restoring clarity and uniformity without a full strip and reseal.

The rejuvenator re-wets the sealer film and lets trapped moisture escape, which is the common cause of that cloudy, patchy look on older sealed concrete. It is a maintenance product for pavers, stamped, stencilled, coloured and exposed aggregate concrete previously sealed with a clear solvent-based acrylic sealer.

Key Features

• Applied by air spray or broom, no special equipment
• For pavers, stamped, stencilled, coloured and exposed aggregate concrete
• Not for water-based, alkyd, epoxy or polyurethane coatings

Specifications

• Application: air spray or solvent-resistant broom
• Dwell: 10 minutes or more, then work in for 30 to 60 seconds
• Cure: 3 to 5 days for the treatment to take effect
• Recoat: wait 4 to 6 weeks before applying a new sealer coat
• Use: external concrete surfaces only

Applications

• Fixing whitening on sealed driveways
• Restoring clarity to hazy pavers
• Treating cloudy stamped and stencilled concrete
• Refreshing aged coloured and exposed aggregate concrete

What You Need to Complete the Job

Test a small area first, apply the rejuvenator evenly and work it in with a broom, then allow 3 to 5 days for the treatment to take effect. If haze persists, a second application may be needed. Recoat with a fresh Dulux Avista sealer such as the General Purpose Matt only after the 4 to 6 week wait. For failed or peeling sealer, use the Sealer Stripper instead. Sealers are in the Concrete Sealers range.

Frequently Asked Questions

What causes the white, cloudy appearance on sealed concrete?

The milky haze, often called blushing, is usually moisture trapped between sealer layers during application. It happens when sealer is applied too thickly, recoated before the previous coat is dry, applied in high humidity, or over concrete with residual moisture. The rejuvenator re-wets the film and lets the trapped moisture escape.

Can I use this on any brand of concrete sealer?

The rejuvenator is formulated for Dulux Avista clear solvent-based acrylic sealers. It may not be effective, and could react badly, on other brands or on water-based, alkyd, epoxy or polyurethane coatings. If you are unsure what is on the concrete, test a small hidden area first.

How long before I can reseal after treatment?

Wait a minimum of 4 to 6 weeks before applying a new coat of sealer. This lets all solvents from the rejuvenator fully evaporate. Rushing the recoat can trap residual solvent under the new sealer and cause the same whitening you are trying to fix.

Is the rejuvenator a substitute for stripping and resealing?

Not always. It is a first-line treatment for whitening and haze and will often restore clarity and extend the sealer life by years. If the sealer is peeling, delaminating or badly worn, rejuvenation cannot fix structural failure, and stripping and resealing remains the correct course.
