C-Cure can now recommend tile installations directly over certain gypsum-based underlayments. However, these new installation methods require special surface preparation in conjunction with applications utilizing C-Cure’s UNIFLEX 916, ULTRACURE 971 or PRORED 963. UNIFLEX 916 Elastomeric Dry Set Mortar, ULTRACURE 971 Elastomeric Waterproofing Membrane or ProRed Waterproofing Membrane 963 produce tenacious bonds to these high compressive strength gypsum underlayments and provide anti-fracture protection for the tile installation. For more information consult our Technical Bulletins, under Surface Preparation, “Gypsum Cement Floor Underlayments”.
