Guarantee: Manufacturer’s liability

Tools & Cleaning

Lacquer roller, paint gun, sprayer, protective gloves, tarpaulin, paint tray.

The base surface must be resistant, sound, solid, clean, dry and free of humidity.

Use Harmony neutral agent or Harmony degreaser for any cleaning required (to remove grease, oil etc).


Application must be completed within a temperature range of 5° - 25°.

Coverage: 1 litre/10 - 12m2.

Apply a thin and uniform film in a ratio of 1 litre per 10 m2, applied in a single coat.Where a lacquer roller is used, apply a crosswise action to ensure the effective spreading of pore sealant. Do not create any excess thickness.

Where a large area is to be covered, use the 250 or 500 mm PermaPro special floor nozzle, or the PermaPro paint gun.

On an anhydrite screed or smoothed concrete, it is recommended to moisten the base slightly with a microfibre mop before applying.

If the existing soil has a high porosity, a second layer must be applied.

Wait 2 to 4 hours before applying Optimum Lacquer. In winter drying time may take longer.
