Koster SL Protect – Mineral Based Self-Leveling Underlayment 25Kg
Koster SL Protect is a mineral based self-leveling underlayment with high resistance to chemical and mechanical stresses. It is an early loadable, directly useable leveling layer over uneven or coarse concrete
and cementitious screeds. Due to its high chemical resistance it is used to protect against light and medium corrosion and serves as a slowly reacting sacrificial layer in areas of high chemical stress. Koster SL
Protect is further used for fast repairs and protection in agricultural, industrial, workshop, production facilities, commercial and private use buildings. Koster SL Protect is self-leveling from 5mm, but can be feathered out to 2mm with suitable tools.
Koster SL Protect is suitable for all interior and exterior floor leveling applications, especially those in industrial and agricultural areas where high chemical and mechanical resistance is required.
Mix each 25 kg bag of SL Protect with 3.0 liters of potable water. The water is placed in a clean mixing vessel and the powder added while constantly mixing. Use a double paddle mixer and mix intensively for no less than 3 minutes until a flowable, lump free consistency is reached. We recommend to always mix 2 bags with a total of 6.0ltrs of water at once. When feathering out the material in very thin layers below 5mm a maximum of 0.3 liters of water may be added per bag.
Depending on the temperature it may take between 24 and 72 hours for the material to attain a residual moisture content of less than 3 M%.
