Description
While there is no dedicated individual PDF datasheet found online specifically titled Sikafloor®‑318 UV, available resources indicate that Sikafloor®‑317 UV and Sikafloor®‑318 UV share the same official series documentation and SDS bundle.
Material Use:
Sikafloor®-317 UV is a two-component, water-based, low odor, non-yellowing, clear matte aliphatic polyurethane topcoat. It is specifically designed for use as a UV-blocking topcoat for interior Sikafloor® and Sikagard® resin floor and wall systems. Its main function is to reduce gloss and enhance the UV stability and color retention of decorative flooring and wall coatings.
System Components:
- Sikafloor®-317 UV is a finish/topcoat layer and should be used over Sikafloor® or Sikagard® systems.
- Compatible with Sikafloor® PurCem® mortar systems for thermal shock resistance.
- Must be applied as a two-coat system for best performance.
Applications:
- Interior spaces only: floors and walls.
- Ideal for public and commercial buildings, including hospitals, clinics, laboratories, schools, universities, retail spaces, museums, banks, offices, and warehouses.
- Particularly useful where visual clarity and matte aesthetics are important, such as multi-colored flake or quartz systems.
Application Details:
- Mix Ratio: 6:1 by volume (Component A : Component B)
- Application Method: Dip and roll using a 6 mm (1/4 in) low nap lint-free roller. Back rolling recommended for uniform finish.
- Film Thickness:
- Wet Film Thickness: 2 mil
- Dry Film Thickness: ~0.84 mil
