Mixing

For best results, a mechanically powered grout mixer should be used.
Consistency of mixed grout: The quantity of clean water required to be added to a 25 kg bag to achieve the desired consistency is:
- Trowellable: 2.750-3.250 liters
- Flowable: 3.250-3.750 liters
The selected water content should be accurately measured into the mixer. The total contents of the Strugrout N880 bag should be slowly added and continuous mixing should take place for 5 minutes. This will ensure that the grout has a smooth, even consistency.

Health and safety & Cleaning

Strugrout N880 is alkaline and should not come into contact with skin and eyes. Avoid inhalation of dust during mixing. Gloves, goggles, and a dust mask should be worn. If contact with skin occurs, wash with water. Splashes to eyes should be washed immediately with plenty of clean water and medical advice sought.

Strugrout N880 should be removed from tools and equipment with clean water immediately after use.

Fire

Strugrout N880 is non-flammable.
