Installation and Notes
1. To clear the debris, dross and dust, etc before installing the waterstop and keep the base dry;
2. The waterstop must be fixed with nails or adhesive on the surface of the central position, make sure not fall off;
3. The overlap joints of the waterstop must be parallel connection and form a closed, not leaving the breakpoint;
4. The storage and transport of the waterstop avoid moisture, extrusion, deformation;
5. The package box cantains detailed installation instructions, the construction must follow the instruct.
