Mix The Concrete
Read the manufacturer’s instructions carefully as slight deviations can and will affect the final product. The real danger is adding too much water or not getting the colors exactly right. Be sure to know exactly how much cubic footage area you have to fill with concrete. Mix accordingly.
Before mixing the concrete, put on safety glasses, a dust mask and old or protective clothing; the mixing process gets really dusty — and assemble the bucket, concrete, water, pigments and mixer.
Start to mix the concrete with water, alternating the mix and water until all of the mix has been added. Carefully follow the manufacturer's guide to how much concrete you need for the job that you are doing. Precision is important. Mix the concrete for 10 minutes or according to the manufacturer's directions. The best consistency seems to fall in sheets inside the mixer barrel as it turns over.
