Exposed aggregate concrete is a common approach to improving the appearance and functionality of concrete surfaces like driveways, parking aprons, and floors.
The cost to apply average exposed aggregate concrete depends upon surface area, the type and color of stones, special preparation needs, and the labor rate.
In the following table the Labor Cost figure is what the able and prepared DIY persons should expect to save by performing the corresponding tasks.
Exposed aggregate concrete: 500 sq.ft. surface; excavate, prepare, pour, and wash-finish a 2" thick concrete slab with rebar, wire mesh, and aggregate/sand base. Include costs for miscellaneous material, transport, equipment, and waste.
|Item||Unit Cost||Quantity||Line Cost|
|Exposed aggregate finish: medium grade washed colored stones less than 3/8" diameter.||$2.49||per sq.ft.||525||$1,309|
|Upgrade: additional cost to apply decorative acrylic sealant; wet look, non-yellowing, solvent based.||$0.28||per sq.ft.||525||$144|
|Material Cost||$2.91||per sq.ft.||500||$1,453|
|+ Labor Cost (base)||$36||per hour||32||$1,152|
|+ Labor Cost (upgrade)||$36||per hour||15||$540|
|Total Cost||$6.29||per sq.ft.||500||$3,145|
