A:B = 6:1 by volume

Condition product between 18 °C to 30 °C (65 °F to 86 °F) before use. 

Minimum 15 °C  (59 °F)  Maximum 30 °C (86 °F).

Low temperatures and/or high humidity will increase curing time.

Maximum 75%  (during application and curing)

Sikafloor®-317 UV should not be applied when the Relative Humidity is greater than 75 % as curing times will be longer and water will be retained in the film reducing ultimate coating performance.

IMPORTANT:  Water-borne products require moisture to evapourate from the film to cure to full properties. Provide adequate fresh air ventilation to remove the excess moisture from the curing product.

Substrate must be at least 3 °C (5 °F) above the Dew Point to reduce the risk of condensation, which may lead to adhesion failure or "blushing" on the floor finish. Be aware that the substrate temperature may be lower than the ambient temperature.

Minimum 15 °C  (59 °F)  Maximum 30 °C (86 °F).

~2 hours at 23 °C (73 °F)

Note: Care must be taken not to use product beyond its recommended pot life. Material will appear liquid, but is unuseable and will result in poor adhesion.

Curing times will vary according to air and substrate temperature and

relative humidity.

Protect from dampness, condensation and water contact during the initial 24 hour cure period.

Mechanical, chemical and physical properties will be fully achieved at full cure.

Minimum 6 hours  Maximum 24 hours at 23 °C (73 °F) 

Note: If the Waiting / Overcoating Time has passed, the previous coat must be lightly sanded, vacuumed and wipe clean with a solvent damped cloth to remove all traces of dust before applying the next coat.

20 m²/L (800 ft²/US gal) at 2 mil (w.f.t.) / ~0.84 mil (d.f.t.) per coat.
Two (2) coats recommended.

Note: Actual coverage rates and material consumption will depend upon porosity and profile of substrates.  Allowance must be also made for variation in film thickness or number of coats required to achieve complete coverage of surfaces. Test sections are recommended to establish correct coverage.

New Sikafloor® or Sikagard® Surfaces: Sikafloor®-317 UV must be applied within the critical recoat window following the last application of the Sika resin. If the recoat window is exceeded, the existing Sika resin surface must be sanded (abraded) to remove any sheen or gloss. The prepared surface must then be wiped clean with a solvent-moistened rag to remove all traces of dust, dirt or preparation residue prior to application of the Sikafloor®-317 UV topcoat.

Previously Coated Surfaces: Existing coated surfaces must be intact and tightly bonded to the substrate. Completely remove all traces of waxes or sealers, dust, dirt, oil, grease or other contaminates that may inhibit bonding. Hard or glossy surfaces must be abraded and solvent wiped clean to improve performance.

IMPORTANT: Sika Canada strongly recommends that a trial application be carried out to determine compatibility and acceptable performance of Sikafloor®-317 UV with the existing surface, prior to general topcoat works being undertaken. Contact Sika Canada for recommendations.

Mix Ratio:  A:B 6:1 by volume (mix full units only)

Do not hand mix Sikafloor® materials. Mechanical mix only.

Pre-mix each component separately to ensure that any settled material is broken up and all solids are evenly distributed. Uniform clarity and consistencies must be achieved within each component.  The container for Component A (resin) is partly filled and sized to allow use as the mixing vessel for a single unit. Start mixing Component A (resin) using a low-speed electric drill (300 - 400 rpm) fitted with an Exomixer® type paddle (recommended model), ensuring the paddle is kept within the resin to avoid air entrapment. Add Component B (hardener) to the vortex of the resin being mixed and blend for three (3) minutes until a uniform consistency is achieved. During the mixing operations, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once to ensure complete mixing.

Thin film, water-based, matte, or semi-gloss topcoats require the installer to be extremely careful during application to use a consistent technique, in a stable, dust free environment to achieve a high quality finish.  Uniform appearance and reflective gloss will vary depending upon the following factors: 

1. Excessive thickness will yield a glossier cured surface.  It is critical to final appearance to employ enough manpower to retain a wet edge, and not allow the product to flash dry during application to prevent unintended multi-layer overlap marks that increase cured thickness and alter reflective gloss properties.  

Do not apply at thicknesses below or above those recommended as this will result in a variation in gloss level.

2. Control of the microenvironment during application and cure.   Water-borne products require moisture to evaporate from the wet coating to achieve full cure.   Too low an ambient relative humidity (< 30%) will result in flash drying conditions that increase the potential for multi-layer overlap marks.  Too high an ambient relative humidity (> 75%) may cause the coating to skin over retaining moisture in the film that can reduce abrasion resistance and increasing dirt pick-up. 

3. Large open areas with natural lighting through exterior windows and/or bright lighting typically enhance the visibility of gloss variation.  It is Sika Canada’s experience that some areas present conditions that are difficult to achieve a visually uniform finish, free of overlap marks.

Apply Sikafloor®-317 UV by dip and roll method using a 6 mm (1/4 in) low nap lint-free roller. For best results, it is recommended to back roll the wet material in a direction perpendicular to the application. Apply uniformly, avoiding puddles or ridges as they take longer to cure and may remain white, after cure, if very thick. Take care to maintain the ‘wet edge’ during application to minimize the potential for lap lines.

Allow first coat to become hard dry before overcoating, approximately six (6) hours at 23 °C (73 °F). For correct inter-coat adhesion, additional coats must be applied within 24 hours at 23 °C [73 °F] of completing the previous coat. If the recoat time is passed, the existing topcoat surface must be mechanically abraded, vacuumed and wiped clean with a lint-free, solvent-dampened cloth before proceeding.

IMPORTANT:   Sikafloor®-317 UV is a hand applied finish subject to minor variations in appearance and performance due to influences partly beyond Sika Canada’s control.   It is the client’s responsibility to assess suitability throughout the selection and installation process to ensure a satisfactory result. 

Sika cannot accept liability for application related uniformity issues and strongly recommends that a trial application be carried out to determine compatibility and acceptable performance before general application begins.    

Clean tools and equipment immediately with water.  Once hardened, product can only be removed mechanically.
