screed drying times

Screed Drying Times

 

All Screed drys at the same rate unless you use Hydraulic binders, for example, Mapei Topcem.

 

Liquid Anhydrite Screed

  • Drys at 1mm per day but this is all dependant on atmospheric conditions.
  • The minimum thickness of Liquid screed is 35mm on insulated beam and block floors which will be half the drying time of sand and cement
  • You can force dry after 5 days using Dehumidifier or Boiler
  • Tiles can be installed when the screed reads 85% Relative Humidity or less

 

Fast Dry Screed using Hydraulic binders 

  • These work by hydration. Certain chemicals react with the water until they consume all the moisture that is present.
  • Tiles can be installed after 4 days   

 

Gypsol commissioned a report which finds that drying times were identical between Sand and Cement screed and Anhydrite Liquid Screed.

They found the most important factor was atmospheric conditions. (Get the report here)

 

Generally, the most important rule to remember is to keep good airflow throughout the building allowing moisture to escape.
