Uses
RAK GROUT can be used for sealing up to 4 mm joint width ceramic tiles, clinker, quarry tile, mosaics, etc. It is suitable for floors and walls joints internally and externally, including kitchens and bathrooms. To obtain high-resistant characteristics (heavy traffic) or high waterproofing resistance (swimming pools), it is recommended to mix RAK GROUT with instead of water.
Instructions for Use
Surface Preparation
Make sure that the tile adhesive is totally set before applying RAK GROUT. The joints must be clean, free of dust. Clean the joints between tiles and brush before grouting.
Mixing
Measure 3.0 – 3.5 Liters of cold, potable water in the mixing bucket and add slowly 10 kg bag of RAK GROUT under
Application
After mixing, let the material rest for about 10 minutes, then remix and spread using a rubber grout float.
Let the product set for about 20 minutes and then clean with a damp sponge. After the complete hardening, clean all the surface of the tile with a dry cloth.
Cleaning
All used tools should be cleaned with water before the product cures.
Recommendations
- Do not apply RAK GROUT in rainy weather, high winds and sand storms
- Do not apply on surface that has temperature less than 5ºC
- During summer season, working area should be covered to prevent the direct sun e ects. Keep equipment cool and use a cool water
- The product should not be exposed to moving water during application
- Apply RAK GROUT when the joint is totally dry
- In case of very high absorbent tiles or high temperature, dampen the joints with clean water
- It is recommended to grout the joints after 24 hours of tile fixing. Since temperature and humidity conditions a ect the final curing, it is advisable to allow extended periods of cure when temperatures are low and /or relative humidity is below70%
Storage
Store in a dry covered place in original well closed packaging. Shelf life is 12 months if stored as recommended
Health & Safety
RAK GROUT can be harmful to skin as it contains cement powders which may releases alkalis when mixed with water. During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment if necessary. In case of contact with skin, rinse with water and again wash thoroughly with soap and water. If ingested, obtain medical attention immediately. Do not induce vomiting.
