Wall and floor applications

With JACKOBOARD construction boards, uneven walls are easily evened out and cracks isolated, and the boards have excellent thermal insulation properties.

They can be used on practically every substrate, whether uneven and non-adhesive; whether timber or mineral.

  • An old bathroom that needs to be completely renovated.
  • When using JACKOBOARD Plano for wall applications, a screwdriver is used to punch 8 holes (5 per m2) through the board for marking purposes. Dabs of mortar are then applied over these hole markings.
  • JACKOBOARD Plano is aligned to the floor at an angle, pressed onto the substrate and straightened with the help of a spirit level.
  • Once the mortar has hardened, a hammer drill is used to drill the dowel holes and the board is fixed with JACKOBOARD metal plugs. Again, the hole markings help when drilling the holes.
  • To compensate cracks and provide additional thermal insulation in floors, JACKOBOARD Plano is moved back and forth gently to embed it firmly in the tile adhesive, and then straightened with the help of a spirit level.
  • Once all of the butt edges have been filled with glass fibre or sealing tape, the bathroom surfaces can be directly covered with tiles, plaster or filler.

Here is a short overview of the different ways JACKOBOARD can be used. Please refer to our installation notes for more detailed information.

on an even and adhesive substrate

  • full-surface bonding without additional dowelling
  • the substrate must be even and flush, and clean and dust free.
  • reinforce the construction-board joints with JACKOBOARD glass-fibre tape or JACKOBOARD sealing tape

on an even and non-adhesive substrate

  • full-surface bonding and additional dowelling
  • the substrate must be clean and dust free
  • reinforce the construction-board joints with JACKOBOARD glass-fibre tape or JACKOBOARD sealing tape

on an uneven substrate

  • spot bonding and additional dowelling
  • reinforce the construction-board joints with JACKOBOARD glass-fibre tape or JACKOBOARD sealing tape

on timber or metal stud frames

  • secure with universal screws and JACKOBOARD insulation-board discs (timber stud frames)
  • secure with self-tapping screws and JACKOBOARD insulation-board discs (metal stud frames)
  • reinforce the construction-board joints with JACKOBOARD glass-fibre tape or JACKOBOARD sealing tape

as free-standing wall

  • for construction boards with a minimum thickness of 50 mm
  • secure by gluing with JACKODUR assembly adhesive
  • secure by gluing with JACKODUR assembly adhesive and using U profiles
  • secure with U profiles
  • reinforce the construction-board joints with JACKOBOARD glass-fibre tape or JACKOBOARD sealing tape

on wooden floors

  • the substrate must be rigid, able to support loads, dry and clean
  • treat the timber substrate with a suitable wood primer
  • full-surface bonding with a flexible adhesive and also secured with universal screws and JACKOBOARD insulation-board discs
  • reinforce the construction-board joints with JACKOBOARD glass-fibre tape or JACKOBOARD sealing tape

on cement-based floors

  • full-surface bonding
  • reinforce the construction-board joints with JACKOBOARD glass-fibre tape or JACKOBOARD sealing tape
