What is the best method for cleaning Flowpoint off the paving surface?

What is the best way to mix my bedding mortar?

Use a forced action mixer. Water should be added until your mix is moist. A quick on-site test to check your water content – Form a ball by squeezing material in your hand, throw this ball 2 feet in the air and catch. If the ball retains its shape then the moisture content is correct. If the ball breaks apart then there is insufficient water to hydrate the high percentage of cement. Insufficient water content can dramatically affect performance.

What is the best way to mix my primer and Flowpoint grout?

Using a gorilla tub or suitable mixing vessel, add the required amount of water as indicated on the bag, then with a drill & paddle to mix the product slowly add the contents of the bag and keep mixing until a smooth lump free consistency is achieved.

Why do I need to use a primer?
