Description
Bostik Powermix is a high-grade, specially modified acrylic polymer designed to be mixed with Portland Cement to create a flexible cementitious waterproofing membrane.
Note: While you asked for a “without fiber” variant, Bostik’s standard Powermix formulation is natively fiber-reinforced to bridge hairline cracks and handle concrete movements. A standard 4-liter gallon container roughly equals 4 kilograms of liquid polymer.
Product Overview & Specifications
Primary Function: Forms a seamless, monolithic “waterproofed concrete skin” that prevents leaks, mold, and blistering.
Mixing Ratio: Typically mixed with 4.5 kg of Portland cement per 1 gallon (4L) of Powermix liquid polymer.
Approximate Coverage (per 4L gallon): Horizontal surfaces: 4 square meters (at 1mm thickness across 2 coats). Vertical surfaces: 8 square meters (at 0.5mm thickness across 2 coats).
Key Features & Benefits
High Impermeability: Offers superior protection against water penetration
.Crack Bridging: The polymer allows the cured coat to move along with the concrete and seal hairline fractures.
UV Resistant: Contains specialized polymers that withstand prolonged sunlight exposure, making it ideal for exterior use.
Breathable & Anti-Blistering: Features high water vapor transmission, allowing trapped concrete moisture to escape without bubbling the layer.
Tintable: Can be colored using compatible pigments to save on overall painting costs.
