 Instruction for use

An installation of the IMPACTODAN BT is shown in the following pictures:

  1. Extend and seal
  2. Place 1st board
  3. Set as system flooring
  4. Aluminum tape to take away static electricity

 Indications and Important Recommendations

- Differences in height of or above 3 mm in 1 m must be previously leveled with leveling paste.

- The panels must stay at least 48h acclimatizing to the room where they will be installed at a temperature of at least 18 ºC, the relative humidity between 40% and 70%.
- Scotia must have a thickness of at least 15 mm to cover up the expansion gap and it must leave a small separation sealed with a silicone cord.
- Sealing tapes of natural aluminum must be used in order to reduce the static electricity.
- Check the product’s technical sheet on safety.
- For further information, please contact our technical staff.
