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.
 

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.
