Pour a single bag of quick-drying cement powder into a wheelbarrow and add the appropriate amount of water per the instructions on the packaging.
Mix the cement and the water together with a mixing trowel or cement-mixing auger. For this application, a cheap garden or bricklayer's trowel works.
Fill the bucket with the cement mixture until it is full to the brim. If you do not have a sealing lid for the bucket, you must wait for the entire bucket of cement to cure so it does not come out of the bucket when you place it on its side. If you have a lid for the bucket, wait 24 to 48 hours for the cement to cure then fasten the lid to the bucket.
Place the bucket on its side then roll it slowly over the area you want to compact. Overlap each row by 50 percent to ensure you achieve adequate packing.
