Drying between layers:

• 12-16 hours depending on the ambient temperature. Fingerprint check.

Application methods:

• Apply a spoonful of plasters in the mortar

Area preparation:

Concrete infrastructure –

• Polishing until you get white and clean concrete on the walls, thorough vacuuming, primer 450 for wet areas or epoxy fluor primer for dry areas.
• It is possible without a primer layer, but this requires a thorough cleaning of the concrete by polishing.

Primary color:

• On dry concrete – epoxy flour primer.
• On damp concrete – epoxy primer 450.

Application instructions:

• Mix a desired amount of part A with part B in a ratio of 4:1
• Apply the mixture into the hole in the polished and painted concrete, prime and level and apply grout or putty to “zero” height.

Packing:

• 4+1 = 5 liters, 14.4+3.6 = 18 liters
