Tools & Cleaning

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

Clean tools in water after use.


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.

bon produit. La consommation est nettement inférieur à se donner. Pour une fois qu'il reste du produit, je ne peux que dire bravo

Produit qui a l'air de bien marcher, mais grosse problématique de séchage (au bout de 10 jours, ça colle encore). Nous avons essayé de respecter les températures de pose, mais en été il est très difficile de ne pas dépasser les 25 degrés. Cela signifie t il que nous ne pouvons pas utiliser ce produit en été ? C'est compliqué ...
