Application steps

MIXING

Sikafloor® ProSeal W is supplied ready for use. Stir thoroughly with an electric stirrer with low speed (~300 rpm) for 2 minutes before use.

 

APPLICATION

For fresh concrete, apply immediately after finishing techniques have been completed.

For dry shaked topped concrete, apply immediatelty after completion of the power floating operation
Apply in a continuous even film by low-pressure spray unit. The suitability of spraying equipment must be confirmed by trials.
Application also possible by brush or roller.
To achieve the highest visual aesthetics and performance, a second coat is recommended.
Wait for first coat to dry tack free before applying a second coat. (see waiting time / overcoating)

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be removed mechanically.

CLEANING

To maintain the appearance of the floor after application, Sikafloor® ProSeal W must have all spillages removed immediately and must be regularly cleaned using rotary brushes, mechanical scrubbers, scrubber dryers, high pressure washers, wash and vacuum techniques, etc., using suitable detergents and waxes.
