About this product
deka is a high-performance liquid additive engineered for the production of semi-dry cementitious screeds. Its effect extremely enhances the compressive and flexural strength of the screed. Thanks to its integrated processing aid, deka ensures excellent workability, making mixing, pumping, spreading, levelling and smoothing noticeably easier and more efficient.
The result: faster construction progress, superior quality, and maximum reliability on site.
