Cement & Plaster Admixture
SurfaMix C is a water-based, latex-free admixture for cementitious mortars, grouts, renders and plasters that enhances adhesion and bonding on application surfaces. Further, it improves elasticity and reduces cracking, shrinkage and the formation of water absorbing capillaries.
SurfaMix C is an ideal admixture for exterior or interior masonry coatings, patch, repair and re-profiling mortars, mortar grout and as an enhancing agent for adhesive materials used when laying ceramic tiles and stones. It reduces surface dusting on floor screeds/overlays an can be used as a primer to improve the adhesion of surfaces. SurfaMix C improves workability and extends the working time of the mix. Furthermore, it reduces water absorption by up to 70% by reducing the pores in the cement mortar.
In any cementitious mix, the addition of water is essential for setting, curing and the development of mechanical strength. Water promotes a process called hydration. During hydration, individual cement particles react with each other and create a strong and durable solid phase. Most frequently, the hydration process is inefficient, resulting in extensive cracking, failure or poor adhesion of the cured cement. The active ingredients of SurfaMix C control the hydration process and prevent the shrinkage and subsequent failure of the final product. Simultaneously, an extended network of material fills the void volume of the cement and promotes surface adhesion and bonding. This also reduces surface dusting. The final SurfaMix C modified material remains visually unchanged, even though its elasticity and mechanical properties are enhanced. Individual nanoparticles exhibiting water repelling properties coat the pores of the mix and its reduce water absorption. This process results in renders, plasters or cement surfaces that are very resilient to weathering. For example, it prevents unwanted moisture,that may rise through the structure (i.e. rising damp) or penetrate from the outside (i.e. condensation). Finally, the cured cementitious mix is more durable against surface corrosion, negative water pressure, frost threat and extreme weather conditions. As a result, SurfaMix C modified cement surfaces last longer.
