Fill the mixer bucket
Keep a bucket on hand to place the mixer in when you’re not using it. Fill the bucket 3/4 full of water. That way the floor levelling compound won’t stick to the paddle and the bucket won’t tip over when you stick the heavy mixer in it.
Prep the floor leveller bags
Most bags filled with dry cementitious mixes have a vent in the top. It’s there so the bags don’t bust open when they’re handled. Minimise the mess produced by floor levelling compound by keeping the vent side up. Line the open bags up next to the buckets. Mixing is a messy business, so do it outdoors whenever possible. Extreme temperatures can affect the time it takes the leveller to set up, so never mix up super cold leveller or work in the blistering hot sun.
Make a fill bucket
Make a bucket that can be filled quickly. Fill a clear bucket with the proper amount of water and draw a fill-line with a marker on the outside of the bucket. Another option is to drill holes at the fill-line so the bucket will drain to the proper level. Dipping a bucket into a barrel filled with water is a lot faster than filling it with a garden hose over and over again.
