Sikafloor®-315 N

Sikafloor®-315 N is a high solids, low VOC, low odour, highly abrasion resistant aliphatic polyurethane coating.

This high performance resin contains a unique UV blocker technology that provides superior ultra violet light screening properties that significantly improves colour retention values of underlying resin floor systems. Sikafloor®-315 N has excellent clarity when applied as a two-part clear high gloss smooth coating or as a three-part semi-gloss fine aggregate-textured finish with the addition of prepackaged optional wear aggregate that increases traction and scratch resistance.

Recommended uses

Sikafloor®-315 N is typically used in light to heavy traffic areas such as: Laboratories, life sciences, pharmaceutical industries Hospitals, health care facilities Education (e.g. schools and universities). Leisure & culture (e.g. museums, stadiums). Retail spaces (e.g. shopping malls). Manufacturing facilities and warehouses.

Features

• Smooth high gloss aesthetic finish (without optional wear aggregate)
• Semi-gloss fine aggregate texture provides improved traction (with optional wear aggregate)
• Durable, impermeable and seamless
• Superior mechanical and chemical resistance
• Enhanced stain-resistance
• Easily cleaned and maintained
• Low VOC-content, low odour

Product Temperature

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

Ambient Air Temperature

Minimum: 10 °C (50 °F) / Maximum: 30 °C (86 °F) Note: Mixing carried out under conditions where the Sikafloor®-315 N temperature and ambient temperature are below 18°C (65°F) will result in reduced product workability and slower curing rates.

Relative Air Humidity

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

Dew Point

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.

Substrate Temperature

Minimum: 10 °C (50 °F) / Maximum: 30 °C (86 °F) Note: Any attempt to apply Sikafloor®-315 N at substrate temperature conditions less than 18 °C (65 °F) will result in an increase in viscosity and slower cure rates.

Substrate Moisture Content

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).

Pot Life

Material Temperature Time 10 °C (50 °F) ~50 minutes 20 °C (68 °F) ~25 minutes 30 °C (86 °F) ~15 minutes 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.

Curing Time

Ambient & Substrate Temperature Foot traffic Light traffic Full cure 10 °C (50 °F) ~48 hours ~72 hours ~10 days 20 °C (68 °F) ~24 hours ~48 hours ~7 days 30 °C (86 °F) ~18 hours ~36 hours ~5 days Note: Freshly applied material should be protected from dampness, condensation and water for at least 72 hours. Curing times will vary according to ambient air, substrate temperature and relative air humidity.

Consumption

Smooth Glossy Finish: Sikafloor®-315 N applied at 4.0 m 2 /L to 9.8 m 2 /L (160 ft 2 / US gal to 401 ft 2 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 m 2 /L to 19.7 m 2 /L (534 ft 2 / US gal to 801 ft 2 / 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 between coats; see Surface Preparation section for complete details.

SUBSTRATE QUALITY

Concrete surfaces must be clean and sound. The compressive strength of the concrete substrate should be at least 25 MPa (3625 psi) at 28 days and a minimum of 1.5 MPa (217 psi) in tensile strength, at the time of the application.

CLEAN UP

Clean all tools and equipment with a non-flammable solvent. Once hardened, product can only be removed mechanically.
