Step 1
Build a canonical concrete block wall . Outline the courtyard sphere with stake and mason ’s string . Square the corners with 3 - 4 - 5 measurements . measurement with a tape measure 3 feet down one wall , 4 feet down another and connect the ends in a trilateral ; if that slanted bank line is 5 animal foot , the corner is square . Mark all wall .
Step 2
Dig a trench with a shovelful for concrete terms , twice as wide and a third as high as the bulwark . For a distinctive block wall 6 feet high , the deep would be 16 inches - by-2 feet . Place a layer ofcompacted gravelin the bottom of the trench , and install 1/2 - column inch steel reinforcing saloon ( rebar ) vertically at all recess and every 4 feet in between . go down the rebar into the ground to the finished height of the wall .
Step 3
Step 4
Pour concrete into the deep . Mix it in a wheelbarrow using a prepared mixing or charter a concrete provider . Fill the deep to solid ground degree and smooth the top with a rectangular mason ’s trowel . Let the concrete cure 72 hours .
Step 5
Lay a first course of action of pulley in a 1/2 - in buddy-buddy bed of howitzer on the terms . habituate block with full ends and set auction block firmly into the mortar but without any mortar between oddment ; hindquarters ends tightly together . ensure the blocking tops are point the integral duration of the wall , using a feeling level and the string rule of thumb to keep blocks square . Lay a meanspirited course of blocks on all court walls .
Step 6
Step 7
Add other courses , stacking pulley tightly together without trench mortar and overlap blocks at nook . Place block over the rebar at those points , with the rebar in the holes in the cube . Stack block to the desired tallness . Fill rebar joints with concrete grout , let that bring around and add 2 - inch or 4 - inch strong blocks on top as a cap . Seal the walls with a 1/8 - in dense layer of control surface bonding cement on both side of the paries to secure the blocks .
Step 8
Spread a base or scratch coat of stucco over both sides of all walls , 3/8 - inch wooden-headed , using the rectangular trowel . Scratch horizontal line in it with the notch bound of the trowel , a broom or a leaf rake . Let that cure 72 time of day and add a 2d or chocolate-brown coat 3/8 - inch thick . Smooth this coat with a farseeing instrument panel pulled down the wall from top to bottom ; remove excess material at the bottom . Let that cure 24 hour .
Step 9
Step 10
polish off the stucco courtyard with a final coating of stucco , 1/8 - column inch thick . Smooth this with the trowel or apply a texture . Make convolution or part - roofy with the notched sharpness of the trowel , or give it a stippled or popcorn surface by pulling stucco up with the flat bottom of the trowel , then smoothing those tip with the flavourless bound . Let this coating cure 24 hour .
