Application

Suitable for both commercial and domestic buildings. Particularly for use with under floor heating.

Description

It is the most popular screed in the range and is a blend of Gyvlon binder, special additives and selected aggregates mixed with clean potable water to produce a pumpable, self smoothing, flowing screed (manufactured to BS EN 13813).

It is designed to provide a smooth level surface in both commercial and domestic buildings prior to the application of floor finishes. It can be used bonded, unbonded or floating and is particularly suitable for use with under floor heating.


Features and benefits:

  • Avoids the need for reinforcement.
  • Easily achieves SR2 finish as described in BS 8204.
  • Environmentally friendly - recycled content of 98%, VOC free, 100% recyclable.
  • Excellent thermal conductivity.
  • Extremely low shrinkage - does not curl and minimizes the risk of cracking.
  • Increased productivity - 2000 m²/day can be easily achieved.
  • Large bay sizes of up to 1000 m² depending on application (heated floors 300 m²).
  • Minimal thermal expansion (0.012 mm/mK).
  • Non combustible (tested to BS 476-4).
  • Protein free - cannot harbour harmful bacteria.
  • Self compacting.
  • Self curing.
  • Significantly reduced thickness when compared to traditional sand/ cement screed.
  • Weight saving as a result of thinner section.
  • Can be force-dried after 7 days.
  • Can be walked on in 24-48 hours.


Primer:

Requires priming prior to application of adhesives; generally acrylic dispersion or water based epoxy.


Product Options:

Sub base:

Gyvlon screeds are suitable for application to most types of sub bases, demonstrating an excellent degree of dimensional stability (maximum shrinkage/ expansion on drying of 0.02%) when compared to traditional sand/ cement based screeds.


Application thickness (minimum):

  • Bonded: 25 mm.
  • In contact with substrate: 30 mm.
  • Unbonded: 30 mm.
  • Floating commercial: 40 mm.
  • Floating domestic: 35 mm.
  • Underfloor heating: 25 mm (30 mm nominal) cover to pipes, heating elements.

Drying time:

  • Dries at a rate of 1 mm per day up to a screed depth of 40 mm in good drying conditions.
  • Can be walked on in 24-48 hours.
  • Can be loaded after 7 days.
  • Can be force dried as early as 7 days after application.
