Mastic waterproof coatings

Polymers and additives for mastic waterproofing formulations

Mastic waterproof coatings are one-component ready-to-use coatings that can be rolled or sprayed onto horizontal and vertical surfaces on various substrates.  In above-grade applications, these waterproofing membranes prevent water intrusion into construction elements.

BASF’s portfolio offers depth and breadth of technological knowledge in raw materials for ready-to-use mastic waterproofing coatings including styrene acrylic and styrene butadiene latex polymers as well as formulation additives to optimize performance.

  1. 1
    ACRONAL® 4040
    Styrene-acrylic copolymer designed for water-based concrete cure and seal coatings to deliver both benefits of a curing agent and sealer in a single coating application.
  2. 2
    ACRONAL 4160
    Styrene-acrylc emulsion polymer ideal for waterproofing coatings on masonry/concrete surfaces. Formulated coatings resists standing water, withstands negative-side hydrostatic pressure, prevents water intrusion.
  3. 3
    ACRONAL 5041
    Multi-purpose styrene acrylic copolymer dispersion for various low-emission applications including waterproofing over various substrates. Fast drying with superior adhesion and good crack bridging properties.
  4. 4
    STYROFAN® NX 1492
    Styrene butadiene dispersion for flexible waterproofing membranes below tiles, over concrete. Coatings feature excellent water resistance, low moisture vapor transmission, and good adhesion.
