Information
System Structure
Curing compound 1 - 2 coats
Application Details
Consumption / Dosage
0.1 - 0.2 l/m2 /coat (5 - 10 m2 /l coat)
To conform to ASTM C-309, ensure a total of 0.2 l/m2 is applied.
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.
Substrate Quality
Fresh concrete:
Surfaces must be free of bleed water and of sufficient strength to withstand finishing
operations.
Hardened / old concrete:
Surfaces must be sound, open textured, clean, free from frost, laitance, surface
water, oils, grease, coatings, all loosely adhering particles and other surface
contaminants.
If in doubt apply a test area first.
Substrate Preparation
Fresh concrete:
The concrete must be prepared by suitable power or manual floating/tamping
techniques.
Hardened / old concrete:
The substrate must be prepared by suitable mechanical preparation techniques
such as high-pressure water or abrasive blasting cleaning equipment.
All dust, loose and friable material must be completely removed from all surfaces
before application of the product, preferably by brush and/or vacuum.

Dew Point
Beware of condensation!
The substrate and uncured floor must be at least 3°C above dew point to reduce
the risk of condensation or blooming on the floor finish.
Application
Instructions
Mixing
Sikafloor® -ProSeal-22 is supplied ready for use. Stir thoroughly before use.
Mixing Time
2 minutes
Mixing Tools
Electric stirrer with low speed (~ 300 rpm)
Application Method /
Tools
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 second coat.
Cleaning of Tools
Clean all tools and application equipment with Thinner C immediately after use.
Hardened / cured material can only be removed mechanically.
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
Waiting Time /
Overcoating
Times are approximate and will be affected by changing ambient conditions,
particularly temperature and relative humidity.
Notes on Application /
Limitations
In hot weather (above +25°C) store Sikafloor® -ProSeal-22 in a cool place prior to
use.
In low temperatures (below +10°C) the product may thicken and reduce
sprayability.
Do not use sprayers, which have been used to spray silicones or release agents.
Do not mix differing formulations of Sika® or other curing membranes.
Ensure spraying equipment is cleaned thoroughly before use and residues of
previous membranes are removed.
Sikafloor® -ProSeal-22 must be mechanically removed prior to the application of a
coating system.
Sikafloor® -ProSeal-22 increases abrasion resistance compared to C25 concrete,
but will gradually de-grade and be removed by environmental exposure conditions
and trafficking.
Do not use outside over white and non absorbent substrates, as some yellowing
may be perceptible.

Sikafloor® -ProSeal-22
Methods
To maintain the appearance of the floor after application, Sikafloor® -ProSeal® -22
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.
