Gypsol XS, a high strength screeding solution, for use in projects that experience superior strengths and higher loadings.

Application

Gypsol XS liquid screed is formulated especially for projects where higher loadings and wear and tear are more likely. Commercial projects such as:

  • Theatres.
  • Data storage facilities.
  • Hospital operating facilities.


The screed is suitable for the encapsulation of an underfloor heating system, either electric or warm water. It can be used to produce a smooth, flat, and level floor to form the subbase for subsequent floor coverings for internal floors.


Customers are specially trained screeders who use specialized equipment to pump the floor into place. Gypsol XS provides a high-strength, cost-effective, and environmentally friendly alternative to cement-based screeds. Combine this screed with the unique Gypsol Rapide fast-drying additive to produce drying times of just 14 days at 50 mm deep in the correct drying conditions.

Description

Gypsol XS is an enhanced strength liquid screed, suitable for areas where higher than usual loadings are experienced.


Gypsol Binder is an integral component of Gypsol XS, an enhanced strength-flowing screed. It is suitable for use in residential and commercial properties, including car showrooms, domestic garages, gymnasia, hospital operating theatres, and other applications where higher loadings and more durable screeded floors are required. Gypsol XS can be used with or without embedded underfloor heating.
