How to Use Fosroc Conbextra GP2
Pro Tip: Always ensure the substrate is clean, sound, and pre-soaked with water for several hours before application to prevent premature drying.
Preparation: Remove all dust, oil, and loose debris from the application area.
Mixing: Use a mechanical grout mixer for best results. Add the required amount of water (typically 4.0 to 4.5 liters per 25kg bag for a flowable consistency).
Placement: Pour or pump the grout continuously from one side only to avoid air entrapment.
Curing: Once the grout has reached its initial set, cover exposed areas with wet hessian or a curing compound like Concure.
