Cementitious waterproof coatings

Polymers and additivs for cementitious waterproofing formulations

Cementitious waterproof coatings are typically two-component blends used behind tile, over masonry patching, and over concrete surfaces. These above and below-grade waterproofing coatings have good affinity to concrete and masonry substrates due to their cementitious nature, and thus strong bonding strength. The polymer modifier contributes to the flexibility properties.

BASF’s portfolio offers depth and breadth of technological knowledge in raw materials for high performance two-component cementitious waterproofing mortars including acrylic and styrene-acrylic emulsion polymers as well as formulation additives to optimize performance.

Binders

ACRONAL® S 400Styrene acrylic latex binder ideal for two-component flexible cementitious waterproofing over concrete. Coatings feature low water absorption and vapor permeable.
ACRONAL 4924All acrylic latex binder ideal cement-based waterproofing coatings over concrete. Coatings feature good water resistance and freeze/thaw capability. Low odor, ammonia-free with potential for drinking water applications.
ACRONAL 5442Styrene acrylic latex binder for high-performance 2K flexible cementitious waterproofing coatings. Potential for drinking water applications. Formulated coatings feature excellent crack-bridging properties, even at lower temperatures down to ca. -10 to -20C.

Additives

FOAMASTER® MO NXZ
General purpose, broad spectrum mineral oil defoamer for water-based formulations.
MELEMENT® L 10Sulphonated melamine superplasticizer ideal for use with concrete. Optimized for plasticization and water reduction of cement-based materials.
