Curing Time
Applied Product ready for use
| Substrate temperature | +10 °C | +10 °C | +30 °C |
| Foot traffic | ~ 4 hours | ~ 3 hours | ~ 2 hours |
| Full cure | ~ 24 hours | ~ 20 hours | ~ 16 hours |
Note: Times are approximate and will be affected by changing ambient and substrate conditions.
Waiting Time / Overcoating
Allow previous coats to become tack free before applying additional coats.
| Substrate Temperature | +10 °C | +20 °C | +30 °C |
| Time | ~ 60 minutes | ~ 25 minutes | ~ 20 minutes |
Times are approximate and will be affected by changing substrate and ambient conditions, particularly temperature and relative humidity.
Consumption
0.1 - 0.25 l/m2/coat. (4 - 10 m2/l/coat)
This figure is theoretical and does not include for any additional material required due to surface porosity, surface profile, variations in level and wastage, etc.
MIXING
Sikafloor® ProSeal-90 is supplied ready for use. Stir thoroughly before use for a minimum of 2 minutes using a low speed electric stirrer (~300 rpm).
APPLICATION
For fresh concrete, apply immediately after finishing techniques have been completed.
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.
CLEANING OF TOOLS
Clean all tools and application equipment with Sika® Thinner C immediately after use. Hardened / cured material can only be removed mechanically.
CLEANING
To maintain the appearance of the floor after application, Sikafloor® ProSeal-90 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.
