Belfast R&D Lab — Successful tile installation is deeply dependent on the chemical compatibility of the primer-concrete interface. Fresh cast concrete displays high alkalinity (pH values between 12 and 13.5) due to calcium hydroxide molecules. Standard PVA glue and cheap organic primers undergo alkaline hydrolysis in this environment, turning into a soapy, weak layer that delaminates under load.
EuroFix advanced acrylic primers utilize specialized alkali-resistant copolymers. These organic molecules display indestructible stability under high-pH environments. Upon application, they penetrate deep into the substrate, polymerize permanently, and form an elastic, breathable film that isolates the cement mortar from high alkali reactions.
