Application

Application Information

Mixing Ratio

5.0 - 5.2 litres of cool, clean water per 20 kg bag.

Layer Thickness

Minimum 3 mm to maximum 15 mm

20 kg bag:
15mm min. to 30mm max., with approx. 30% by weight addition of 0.7 to 1.2 or 1.0 - 2.0mm of quartz sand per bag. (i.e. 6 kg per 20 kg bag.)

Ambient Air Temperature

Minimum +10°C / maximum +25°C

Substrate Temperature

Minimum +10°C / maximum +25°C

For increased surface strength and good adhesive strengths - also with aqueous adhesives - it is recommended to work at air and substrate temperatures between +15°C and +25°C.
In cold weather tempering of Sika® Level-315 F is recommended.

Pot Life

~ 30 minutes at +23°C and 50 % r.h.

Higher temperatures accelerate setting, lower temperatures reduce setting of the product.

Waiting Time / Overcoating

At +23oC and 50 % r.h.

Walkable after

~ 3 hours (without load)

Ready for covering with tiles

~ 4 - 6 hours

Ready for covering with parquet with 3 mm thickness~ 24 hours

Prior to application of Sika® Level-315 F, ensure that the maximum moisture content for the subsequent coating is achieved. (See the corresponding standards and information sheet of the subsequent coatings or adhesives).

Application steps

MIXING

When mixing manually, place 5.0 - 5.2 litres of cool, clean water in a suitable sized mixing vessel. Add a full bag (20 kg) of Sika® Level-315 F powder slowly to the water, mixing (slow speed 300-400 RPM) continuously to achieve a homogeneous and lump-free mix (at least 3 minutes). After mixing thoroughly, leave the material to stand in the container for two or three minutes until the majority of air bubbles have dispersed.

APPLICATION

Pour Sika® Level-315 F onto the floor and smooth with a trowel to the desired layer thickness. To improve floating and deaeration use a swab bar at a higher layer thicknesses.

Important!

  • Avoid rapid drying.
  • Protect from direct sunlight and drafts.
  • Higher temperatures of the powder and the mixing water accelerate the setting of Sika® Level-315 F.  Lower temperatures delay setting.

CLEANING OF TOOLS

Clean all tools and equipment immediately after use with water. Hardened material can only be removed mechanically.
