This product can be mixed with a force action mixer if it is to be applied by machine or with a low-speed hand drill mixer if it is to be applied by hand. If you're applying a very small amount, you can also mix this product by hand. You should pour the required amount of water into a mixing container and then add the powder while stirring and mixing the product thoroughly for a minimum of three minutes. Additional water can be added to reach the required consistency.
When used as a repair mortar, this product can be applied by hand or using wet spray techniques. The substrate should be wet thoroughly for two hours before the application and should be kept wet and not allowed to dry out. Before applying Sika monotop 615 remove any excess water with a sponge or cloth. A scratch coat should be applied when adding this product manually. When vertical applications are required, these should be built up in layers from the bottom upwards. Use a float to finish the surface to required textures. Too much trowelling can cause surface cracking.
