Elakor-PU Floor Sealant — polyurethane sealant for movement joints
Two-component polyurethane sealant for thermal and movement joints in concrete floors, elongation at least 400 %.

This three-component polyurethane-cement compound flows into a semi-matt coating that withstands continuous heating up to +70 °C and short-term heating up to 150 °C for 2 hours. It is designed for light and moderate intensity of mechanical exposure per SP 29.13330.2011 in workshops, warehouses, car parks, and food and pharmaceutical production. Substrate moisture is not limited, concrete must be at least M350; compressive strength is 56 MPa, flexural strength 20 MPa, foot traffic after 24 hours.
