Application steps

MIXING

Sika® FloorFix should be mixed to the following ratio: 100 parts Sika® FloorFix : 22.5 parts water by weight. Always add powder to water. Use mechanical stirring only.

  • For mixes up to 10 kg, mix using a low speed/high torque electric hand drill fitted with a Sika Spiral Mixer.
  • For quantities greater than 10 kg use a forced action pan mixer, eg Hobart Berkel Mixer.
  • Add powder to cold water while stirring, and stir vigorously for a minimum of two minutes after final addition and until mix is thoroughly and uniformly wetted out. After initial mix, do not remix or add further water.

APPLICATION

  • Working time is approximately 10 minutes at 20°C, and will be shorter at higher temperatures and longer at lower temperatures.
  • Initial adhesion is best obtained by working mixed Sika® FloorFix hard against the damp repair surface using a gloved hand. Build up to 20 mm on vertical and 40 mm on horizontal surfaces, and finish profiles with steel tools as required. For higher builds, wait until first layer has partially set (approximately 30 minutes), score the surface for increased adhesion, and lay freshly mixed Sika® FloorFix as necessary.
  • Sika® FloorFix should preferably not be used in direct sun because premature drying may occur. In all circumstances repaired areas should be kept damp by mist spraying for at least 1 hour after application to prevent risk of premature surface drying and cracking.
  • Initial set between 10 and 30 minutes at 20°C depending on thickness and substrate temperature.
  • Sika® FloorFix may be lightly trafficked after approximately 2 hours.

CLEANING OF TOOLS

Clean uncured material with water. Mechanical action will be required to remove cured material.
