Sikafloor 2 Syntop 2 SCD ® is a heavy duty cementitious surface topping produced using very high abrasion resistance aggregate (corundum) and special metallic aggregate to provide extra protection against impact. Sikafloor 2 Syntop 2 SCD® toppings exhibit high compressive strengths, resulting in an extremely durable surface finish. Abrasion resistance tests have shown Sikafloor 2 Syntop 2 SCD® to have much higher the wear resistance than that of plain concrete.
