TENEREZZA<\/a> adesivo per piastrelle<\/a> formulations are based on P.O 42.5 Ordinary Portland Cement<\/strong> as the core binder, combined with graded quartz sand and TENESSY proprietary polymer additive systems. Strictly aligned with industry standards, the formulations cover the four mainstream strength grades: C1, C1T, C2, and C2T<\/strong>.<\/p>

These formulations balance bond strength, workability, anti-slip performance, and cost efficiency<\/strong>, and can be directly applied to industrial production and engineering projects.<\/p>

All formulas below are expressed in kg per ton (1 ton of dry-mix tile adhesive)<\/strong> and are suitable for indoor and outdoor applications, various tile sizes, and different working conditions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
