Kerakoll has relaunched Keracem Eco, its hydraulic binder for high-performance screeds and heat-radiant slabs.
When mixed with sand, the product produces screeds compatible with any type of finished flooring including hardwood, resilient materials, PVC, carpets, ceramic tiles and natural stone. Since it was launched in 2005, the company says, tens of millions of bags have been produced which have been used to lay hundreds of millions of metres squared of screeds and it is now sold in over 62 countries throughout the world.
It’s a normal setting, rapid drying product with improved workability and a pot life of up to 3 hours, and the high-performance cements included reportedly minimise the amount of the product needed to bind the screed. The product is ready for foot traffic after approximately 8 hours, tiling after 24 hours and laying of LVT, sheet vinyl and hardwood floors after 5 days.
The product’s performance levels are said to be made possible by an optimised water/cement ratio, as well as the fact it compensates for hygrometric shrinkage, reducing the formation of surface cracks. The binder also compacts easily, reportedly giving the finished screed excellent thermal conductivity and making it suitable for use with radiant heating and cooling systems.
Finally, like all the company’s products, it has been developed to be as eco-friendly as possible without compromising its performance values. The hydraulic binder is classified as GEV Emicode EC1 R Plus, meaning it has low VOC emissions and can be recycled as an inert mineral material at the end of its life, reducing its environmental impact.
