Installation
- Remove dirty and dust from the parts to join;
- Put in a container 2,5l of water every 10 kg of RefMix. Pour slowly and mix until obtaining an elastic mixture;
- Spray water or wet with a sponge parts to join;
- Apply RefMix spreading it homogeneously (minimum 10 mm of thickness) and join the parts;
- When work completed, keep parts wet, for a few hours, to allow RefMix to adhere homogeneously.
