Application of Perlite Bplus & Perlite B1.

1. Application
  • Filling up floors at a thickness of 4cm up to 1 cm in one go
  • For larger thickness two or more successive layers can be applied, at intervals of about 3-4 hours
  • The application surface has to be dust-free and clean
  • The application surface needs to be leveled Watering of the sub-surface
  • For fillings up to 4cm (Perlite Bplus) we recommend the addition of adhesive re-enforcer
  • We then are ready to apply our lightweight concrete

2. Preparing the Mix

  • Per four 50-litre bags we add one 50-kilo bag of cement.
  • In the mix we add up to 50 litres of water in order to achieve the required fluidity level.
  • We put Perlite Bplus or Perlite B in the pumping machine We add cement and we mix
  • We add water and we mix


  • In the first day of the application the spraying of the surface with a thin layer of water is necessary to prevent cracks
  • Brushing should be carried out the same day or at the latest the day after
  • For better results we recommend the use of piston/pumping machines
  • For external surfaces (roofs, balconies, etc) we recommend applying water-resistant insulation (in liquid form) prior to applying tiles 7-15 days required for drying up
