Description

Bostik Powermix is a high-grade, specially modified acrylic polymer liquid membrane used for flexible cementitious waterproofing. It is important to note that the standard, widely available formulation of Bostik Powermix is natively fiber-reinforced.

When users look for a “without fiber” variant or refer to a “16kg” unit, they are typically referring to the 16-Liter liquid pail (which weighs roughly 16–17kg) or they are comparing it to 2-component powders that include pre-mixed fibers. Powermix functions as a liquid concentrate designed to be mixed directly with standard, smooth Portland Cement to form a seamless, waterproof skin.

Key Product Features

Superior Water Impermeability: Creates a heavy-duty, seamless barrier that seals concrete against high hydrostatic pressure.

Crack Bridging & Flexibility: Moves naturally with concrete structures to bridge hairline and micro-cracks over time.

UV & Weather Resistant: The high-grade polymer blend withstands direct sunlight, making it highly effective for both exposed outdoor and indoor surfaces.

Breathes and Prevents Blistering: Offers high water vapor transmission, allowing trapped moisture inside the concrete to release without bubbling the coating.

Cost-Efficient & Tintable: It can be tinted to match desired colors, often eliminating the need for a separate decorative topcoat on firewalls.
