Application Information
Mixing ratio (Part A : Part B by weight): 78 : 22
Consumption (self-smoothing): ~1.8 kg/m²/mm (1L/m²/mm) - theoretical. For detailed info, please refer to the System data sheet Sikafloor® Multidur ES- 23 / 24 and Sikafloor® Multidur EB-24.
Ambient air temperature: +10 °C min. / +30 °C max.
Relative air humidity: 80 % r.h. max.
Dew point: Substrate and uncured floor must be at least 3 °C above dew point.
Substrate temperature: +10 °C min. / +30 °C max.
Substrate moisture content: < 4 % pbw (refer to datasheet for priming requirements for higher moisture).
Pot Life: ~ 60 minutes at +10 °C, ~ 30 minutes at +20 °C, ~ 15 minutes at +30 °C.
Curing time (before overcoating): Minimum 16-30 hours depending on temperature, maximum 1-3 days.
Important Considerations
- Do not apply on substrates with rising moisture.
- Do not blind the primer.
- Protect freshly applied floor from damp, condensation, and water for at least 24 hours.
- Ensure consistent batch numbers for colour matching across areas.
- Underfloor heating and high point loads may lead to imprints.
- Use only electric powered warm air blowers for heating.
Application Instructions
Refer to Sika Method Statements for substrate evaluation and preparation, mixing and application of flooring systems, and Sikafloor cleaning regime.
Substrate quality / pre-treatment
Concrete substrate must be sound (min. 25 N/mm² compressive strength, 1.5 N/mm² pull off strength), clean, dry, and free of contaminants. Prepare mechanically (abrasive blast cleaning or scarifying) to remove laitance and achieve an open texture. Repair defects with appropriate Sikafloor, Sikadur, or Sika Gard products. Remove all dust and loose material.
Mixing
Stir Part A mechanically. Add all of Part B to Part A and mix continuously for 3 minutes until uniform. Add quartz sand and Extender T (if required) and mix for another 2 minutes. Pour into another container and mix again. Avoid over mixing to minimize air entrainment. Use a low speed electric stirrer (300-400 rpm) or suitable forced action mixer for mortars.
Application
Confirm substrate moisture, humidity, and dew point. Prime with Sikafloor 161/-160 to ensure a pore-free coat (apply by roller then squeegee). Level rough surfaces with Sikafloor levelling mortar if needed. For a smooth wearing course, pour and spread Sikafloor-263 SL evenly with a serrated trowel or pin rake, then roll immediately with a spiked roller in two directions to ensure even thickness and remove entrapped air. For a broadcast system, pour and spread, roll with a spiked roller, and after ~15-30 minutes (at +20 °C), broadcast with quartz sand to excess. Once hard, remove excess sand and apply Sikafloor 264 finish coats (usually 2 coats at 2-3 m²/L for the first and 5-6 m²/L for the second coat).
Cleaning of equipment
Clean all tools and application equipment with Thinner C immediately after use. Hardened material can only be removed mechanically.
Maintenance
Clean spillages immediately and clean regularly using appropriate methods and detergents.
