Thin set mortar typically does not adhere well to polyurethane surfaces due to the latter's smooth and non-porous nature. For optimal adhesion, it's essential to use a suitable primer or bonding agent designed for polyurethane. Additionally, roughening the surface can enhance the bond between the thin set and the polyurethane. Always consult manufacturer guidelines for the best results.
