Calibrated Five Gallon Buckets
Calibrated five gallon buckets can be used to measure sand added to the mixer. When a cubic foot box is used, a hinged attachment to the mortar mixer can be constructed to facilitate one-man operation. When five gallon buckets are used, they should be calibrated to determine actual volume capacity. For example: if it is determined that buckets being used for proportioning have a volume capacity of exactly five gallons, then, since 1 cu ft is equal to 7.48 gal, 3 cu ft of sand is 22.44 gal or 4½ five-gallon buckets of sand. To obtain a mortar having a 3 to 1 volume proportion of sand to cementitious materials, 4½ five-gallon buckets of sand would be added to the mixer for each bag of masonry cement or cubic foot of cement plus lime used in the mortar batch.

CAUTION
CAUTION: Contact with wet (unhardened) concrete, mortar, cement, or cement mixtures can cause SKIN IRRITATION, SEVERE CHEMICAL BURNS, or SERIOUS EYE DAMAGE. Wear waterproof gloves, a long-sleeved shirt, full-length trousers, and proper eye protection when working with these materials. If you have to stand in wet concrete, use waterproof boots that are high enough to keep concrete from flowing into them. Wash wet concrete, mortar, cement, or cement mixtures from your skin immediately after contact. Indirect contact through clothing can be as serious as direct contact, so promptly rinse out wet concrete, mortar, cement, or cement mixtures from clothing. Seek immediate medical attention if you have persistent or severe discomfort.
