Sikafloor® ProSeal application information

Consumption	0.1 - 0.25 l/m2/coat (4 - 10 m2/l/coat). Note: This figure is theoretical and does not include for any additional ma- terial required due to surface porosity, surface profile, variations in level and wastage, etc.
Ambient Air Temperature	+ 10 °C minimum / + 30 °C maximum
Relative Air Humidity	80% r.h. maximum
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.
Substrate Temperature	+ 10 °C minimum / + 30 °C maximum
Waiting Time / Overcoating Note: Times are approximate and will be affected by changing substrate and ambient conditions, particularly temperature and relative humidity.	+10oC = ~ 60mins +20oC = ~ 25 mins +30oC = ~ 20 mins

Limitations

• In hot weather (i.e. above +25 °C), store Sikafloor® ProSeal in a cool place prior to use.
• In low temperatures (i.e. below +10 °C), the Product may thicken and be difficult to spray.
• 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 must be removed prior to the application of a coating system.
• Sikafloor ProSeal increases abrasion resistance compared to C20/25 concrete, but will gradually degrade and be removed by environmental exposure conditions and trafficking.
• As Sikafloor ProSeal is a solvented Product, it may be unsuitable for application in confined spaces or areas with inadequate ventilation. Consideration should also be given to its use close to areas used for food preparation etc. due to odour. If you are in need of guidance on the suitability of this Product for your site, please contact the Sika® Flooring Technical Team at flooring.technical@uk.sika.com

Sikafloor ProSeal Application Instructions

SUBSTRATE QUALITY / PRE-TREATMENT Fresh Concrete:

Surface must be free of bleed water and of sufficient strength to withstand finishing operations. 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-jetting or abrasive blast cleaning.

All dust, loose and friable material must be completely removed from all surfaces before application of the Product, preferably by brush and / or vacuum. If in doubt, apply a test area first.

MIXING

Sikafloor® ProSeal is supplied ready for use. Stir thor- oughly 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 is 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.

MAINTENANCE

CLEANING

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