PC Flooring have a vast amount of experience in the delivery and installation of traditional screed systems.
Traditional floor screeds typically consist of 3 to 5 parts sand and 1 part cement, drying times can vary considerably depending on a number of different variables, the most significant being screed type.
Laying Traditional Screed
Installing a traditional screeded floor involves application with a wooden or plastic float and finished with a trowel or powerfloat. There are different standards of screeded floors defined as surface regularity (SR), we pride ourselves on meeting specification standards.
Fully Bonded Screed
Fully bonded traditional screeded floor systems are laid on a shot-blasted / scabbled concrete base and bonded using an adhesive. Resin systems such as Isocrete K-Screed allow screeds to fully bond at 15mm and can perform as a high end DPM.
Unbonded screeds are a traditional screeding installation method which involves the use of a damp-proof membrane (DPM). Installing a DPM means the screed is not installed directly to the concrete floor, which should theoretically prevent the installation of the screed being effected by any cracks in the sub-base.
Floating screeds are used where there is a need for thermal or acoustic insulation to be installed on the floor. In many cases an underfloor heating system is also installed. To prevent against dry and shrinkage cracking it is essential that the floor is lined with edging foam/isolation.
