Bostik Powermix Block A350

Powermix Block A350 - Flexible, fibre-reinforced and specially modified high-grade acrylic polymer that is mixed with Portland Cement to provide superior water protection and more to concrete surfaces.

Uses: Once the primed surface is dry to the touch, prepare the Powermix cementitious mixture (1 gallon Powermix: 4.5 kgs or 3.5 liters Portland cement) to cover an area of 8sqm. Apply the mixture with a brush as the first coat over the measured area. Allow the first coat to cure for 1-2 hours, then prepare a second mixture and apply it with a roller in the opposite direction of the first coat. Let it dry for 24 hours before conducting a flood test. For exposed areas subject to regular traffic, such as roof decks, a concrete topping is recommended.
