Add eight shovels of clean sand to the wheelbarrow. Distribute the sand evenly along the bottom of the wheelbarrow. Add 1/2 bag of type N mortar, found at any hardware store that sells masonry supplies. Break open the end of the mortar bag with a shovel and pour the contents into the sand. Wear a dust mask prior to working with the mortar, which is caustic and can be harmful to your lungs.

Blend the sand and mortar together with a hoe. Begin at the rear of the wheelbarrow and pull and push the mixture until it is completely blended. Add 2 gallons of water to the blended mixture and continue to mix until you have the consistency of toothpaste or thick pancake batter. Add more water, 1/2 gallon at a time, if the mixture is too dry, and more sand and mortar, one shovel of each at a time, until the mixture is correct.

Allow the mortar to set for 15 minutes after the initial water and powder blend. Add 1/2 gallon of water to the mixture to loosen it up. Use the mortar to lay your bricks, adding small amounts of water to the mix as it dries during use.
