 Instruction for use

An installation of the FONODAN BJ is shown in the following pictures:

  1. Measure and cut
  2. Remove nonstick paper
  3. Stick to the tube
  4. Duplicate in the curve

 Indications and Important Recommendations

- Any adhesive product in order needs a dry and clean surface to stick.
- The product must be cut on top of a clean surface in order to avoid contact of the polyethylene with dust.
- Using bridles ensures a long-lasting adherence between the product and the pipe.
- Install with temperatures above a 10ºC. To maintain its temperature in winter, store to sun light before applying.
- Special caution will be given when the pipes pass through slab, sealing possible spaces between them and FONODAN BJ, with elastic paste with high density.
- Check the product’s technical sheet on safety.
- For further information, please contact our technical staff.
