A:B =1:2 by volume

Condition product between 18 °C to 24 °C  (65 °F to 75°F) before using.

Minimum 10 °C (50 °F)   Maximum 30˚C (85 °F) 

Minimum 30 % /  Maximum 75 % (during application and curing)

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 10 °C (50 °F)  / Maximum 30˚C (85 °F) 

Mixing and Application attempted at Material, Ambient and/or Substrate Temperature conditions lower than 18 °C (65 °F) will result in a decrease in product workability and slower cure rates.

Moisture content of concrete substrate must be ≤ 4 % by mass (pbw – part by weight) as measured with a Tramex® CME/CMExpert type concrete moisture meter on mechanically-prepared surface according to this product data sheet (preparation to CSP-3 to CSP-4 as per ICRI
guidelines). Do not apply to concrete substrate with moisture levels > 4 % mass (pbw – part by weight) as measured with Tramex® CME/CMExpert type concrete moisture meter. If moisture content of concrete substrate exceeds 4 % by mass (pbw – part by weight) as measured with Tramex® CME/CMExpert type concrete moisture meter, use Sikafloor® 1610,or Sikafloor® 81 EpoCem®, or Sikafloor®-22NA or -24NA PurCem®.

When relative humidity tests for concrete substrate are conducted per ASTM F2170 for project specific requirements, values must be ≤ 85 %. If values exceed 85 %, according to ASTM F2170, use Sikafloor®-1610,or Sikafloor®-81 EpoCem®, or Sikafloor®-22NA or -24NA PurCem®.

ASTM F2170 testing is not a substitute for measuring substrate moisture content with a Tramex® CME/CMExpert type concrete moisture meter as described above.

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

Freshly applied material should be protected from dampness, condensation and water for at least 72 hours.

Curing times will vary according to anbient air, substrate temperature and relative air humidity.

Smooth Glossy Finish:
Sikafloor®-315 N applied at 4.0 m²/L to 9.8 m²/L (160 ft² / US gal. to 401 ft² US gal.) at 4-10 mil w.f.t. NOTE: Product will not cure properly if applied at excessive thickness. Do not exceed 10 mil w.f.t.

Textured Semi-Gloss Finish: 

(Requires addition of optional Part C wear aggregates)
Sikafloor®-315 N applied at 13.1 m²/L to 19.7 m²/L (534 ft² / US gal. to 801 ft² / US gal.) 2-3 mil w.f.t. NOTE:  If material is applied too heavy, the aggregate texture may be encapsulated resulting in a smooth glossy surface. Do not exceed 3 mil w.f.t.

IMPORTANT: Multi-coat applications requires additional surface preparation beteween coats; see Surface Preparation section for complete details.

Thinning Solvent - Sika^® Urethane Thinner and Cleaner - maximum 5 % by volume  (50 mL/L / 6.4 oz/US gal.) (if required). Contact Sika Canada for additional information.

Mix Ratio: A:B = 1:2 by volume.

Do not hand mix Sikafloor^® materials. Mechanically mix only.

Where part-mixing of a unit is necessary, ensure that Mix Ratio is accurately achieved. Preferably, do not part-mix units.  Pre-stir each component thoroughly and do not allow mixed material to stand and settle. Failure to pre-stir and keep product agitated will result in variation in gloss levels appareance and performance.

   
Glossy Finish
Empty the entire contents of the Component A (Resin) into the Component B (Hardener). Using a Exomixer® or Jiffy type mixing paddle and drill, mix at low speed (300-450 rpm) for three (3) minutes. Be careful not to introduce any air bubbles while mixing. Make sure the contents are completely mixed to avoid any weak or partially cured spots in the coating. During the mixing operation, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once to ensure complete mixing.

Semi-gloss Finish - Requires use of the optional Wear Aggregate
Empty the entire contents of the Component A (Resin) into the Component B (Hardener). Using a Exomixer® orJiffy type mixing paddle and drill, mix at low speed (300-450 rpm) for one (1) minute. Slowly add the optional Component C (Wear Aggregate) to the mix material under agitation. Mix for two (2) minutes. Note: Do not dump wear aggregate into mix! Be careful not to introduce any air bubbles while mixing. Make sure the contents are completely mixed to avoid any weak or partially cured spots in the coating. During the mixing operation, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once to ensure complete mixing.

 
Do not mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature.

General Requirements: It is extremely important to thoroughly clean the substrate before application of Sikafloor®-315 N. Dust particles, dirt, steel shot and other contaminates will be permanently sealed into the cured film appearing as surface defects on high gloss, thin mil coatings. Roller sleeves should be low nap, lint-free and of high quality to minimize the appearance and frequency of entrapped roller fibres.

IMPORTANT: It is important to keep mixed product fully and mechanically agitated. Any breaks in application should be followed by re-mixing of the material to again produce a uniform consistency, before proceeding with the application.

  
Application of Sikafloor®-315 N for glossy finish using a roller:
Sikafloor®-315 N is applied with a solvent-resistant short nap roller, 6 mm (1/4 in), at 4-10 mil w.f.t The floor area to be coated should be divided into sections that can be done completely in one application sequence. Sections should be divided at expansion joints or doorways when possible. The end of a section should be taped off to form a straight clean edge for an adjacent section. Pour the material in a roller tray and saturate the roller, remove the excess material by lightly rolling it in the tray. It is important to apply the coating uniformly at a rate of 4 to10 mil to achieve proper appearance. If material is applied too heavy, the coating may create micro blisters. If material is applied too thin, the coating gloss level may vary. Product will not cure properly if applied at excessive thickness. Do not exceed 10 mil w.f.t.

  
Application of Sikafloor®-315 N for glossy finish using a flat squeegee (without use of Wear Aggregate):
Pour a thin ribbon of Sikafloor®-315 N onto the floor surface. Using a flat squeegee spread the material at the recommended rate. Avoid leaving puddles on the floor surface. Using a 6 mm (1/4 in) short nap roller, back roll the material in the opposite direction that it was applied with the squeegee. Continue to back roll the material to achieve uniform coverage across the floor. It is extremely important to apply this material at a rate of 4-10 mil w.f.t. To finish, Sikafloor®-315 N should be cross rolled; uninterrupted across the entire width of the floor. This will help reduce roller marks. If material is applied too heavy, the coating may create micro blisters. If material is applied too thin, the coating gloss level may vary. Product will not cure properly if applied at excessive thickness. Do not exceed 10 mil w.f.t.

Application of Sikafloor®-315 N for semi-gloss finish using a roller (Wear Aggregate required):

Sikafloor®-315 N is applied with a solvent-resistant short nap roller, 6 mm (1/4 in), at a thickness of 2-3 mil. The floor area to be coated should be divided into sections that can be done completely in one application sequence. Sections should be divided at expansion joints or doorways when possible. The end of a section should be taped off to form a straight clean edge for an adjacent section. Pour the material in a roller tray and saturate the roller, remove the excess material by lightly rolling it in the tray. It is important to apply the coating uniformly at a rate of 2-3 mil to achieve proper appearance. If material is applied too heavy, the coating may create micro blisters or result in loss of aggregate texture. If material is applied too thin, the coating gloss level may vary. Do not exceed 3 mil w.f.t.

  
IMPORTANT:  It is very important to remix the material often with the roller in the tray to keep the aggregate from settling at the bottom of the mixing container. It is important to remix the remaining material in the mixing container before the material is poured into the tray. This will ensure that the wear aggregate is evenly dispersed in the Sikafloor®-315 N. Cross roll the entire area with straight uninterrupted passes across the entire width of the floor. This will reduce roller marks. If appearance is still not uniform after a few of these passes, repeat this procedure.
