Laticrete Waterproofing 20kg Membrane
The Laticrete Waterproofing 20kg provides a professional-grade, polymer-fortified cementitious coating designed to prevent water ingress in critical structural areas. This single-component powder requires only the addition of water to create a high-bond slurry suitable for negative and positive side hydrostatic pressure applications. It effectively seals concrete, masonry, and cement-based substrates in both residential and industrial environments.
Built for the Job
This waterproofing compound is a standard requirement for contractors preparing wet areas before tile installation. It is specifically formulated to handle the rigors of continuous water exposure in high-traffic zones. Site supervisors rely on this material for its predictable cure times and compatibility with various thin-set mortars and adhesives. It serves as a primary moisture barrier in multi-story developments where leak prevention between floors is mandatory.
- Internal wet area tanking including shower recesses, bathrooms, and commercial laundries.
- External moisture protection for balconies, podium decks, and rooftops prior to finishing.
- Submerged applications such as swimming pools, water features, and potable water tanks.

On-Site & Workshop Notes
- Ensure the substrate is structurally sound, clean, and free of oils or curing compounds before the first coat.
- Mix the powder using a low-speed drill and paddle mixer to prevent excessive air entrainment in the slurry.
- Apply in two perpendicular coats to ensure total coverage and eliminate pinholes in the membrane surface.
- Allow the material to dry completely between coats; typical wait time is 2 to 4 hours depending on site humidity.
