Rapid screed
Rapid screed is a traditional sand and cement dry screed mix engineered to reduce drying times and allows the 1st heating cycle to be carried out after only 15 days.
Rapid Screed has the additional benefits including improved plasticity, reduced porosity, reduced shrinkage properties, and improved thermal conductivity.
Features and benefits
Compressive strength
Greater than 20N/mm² at 7 days and greater than 30N/mm² at 28 days
Flexural strength
Greater than 3N/mm² at 7 days and greater than 6N/mm² at 28 days
Set to foot traffic
Greater than 3N/mm² at 7 days and greater than 6N/mm² at 28 days
Waiting time before commisioning heating system
15 days
Residual moisture after 14 days
2.0% or below at screed thickness of up to 75 mm
Measuring the moisture content
Before laying flooring sensitive to moisture always check the relative moisture level of the screed using the calcium carbide method.
Increased plasticity and workability
Reduces porosity and hygrometric shrinkage, speeds up and increases development of mechanical strength and improves thermal conductivity.
