Precautions for construction
- Do not overlay MEJIFIT.
- If the base around joints has a level difference, apply polymer-cement-based touchups.
- Leave a space of about 2 to 3mm between parts joining MEJIFIT.
- After adhesion of MEJIFIT, compact the surface with a roller.
- Handle with care so as not to be injured by the edge of the ultrathin sheet in the surface layer of MEJIFIT.
- If MEJIFIT is curled, uncurl it before adhesion.
- Confirm primer and other treatment with the manufacturer of the new waterproof layer.
- Note that a wet concrete base will reduce the adhesive force of MEJIFIT.
- In case of adhesion system, confirm with the manufacturer of the new waterproof layer.
