Protecting exterior surfaces can also be achieved by installing a KÖSTER self-leveling underlayment. In order to achieve excellent bonding to the following underlayment, the prepared substrate is primed with KÖSTER SL Primer. KÖSTER SL Primer works as a bonding agent to provide a homogeneous absorbency and to bind residual dust. KÖSTER SL Primer cures rapidly and is quickly recoatable.
KÖSTER SL Protect is an early loadable, mineral based self-leveling underlayment which provides high resistance to chemical and mechanical stresses. It can be used as a directly trafficable 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.
KÖSTER SL Protect is further used for fast repairs and protection in agricultural, industrial, workshop, production facilities, commercial, and private use buildings. KÖSTER SL Protect is self-leveling from 5 mm to 30 mm and can be feathered out to 2 mm with suitable tools.
Always adhere to the specifications in the respective Technical Guidelines.
