Cost of stamped concrete materials for your patio

In total, the material costs for a 200-square-foot stamped concrete patio can range from $580 to $890, or £435 to £680. This estimate does not include labour and additional costs like sealers. Lets break that down below though:

The primary material, concrete, typically costs around $100 to $150 per cubic meter, equivalent to £75 to £115. For a standard patio with a depth of 4 inches, you'll need about 0.01 cubic meters of concrete per square foot, translating to approximately $1.20 to $1.80 per square foot, or £0.90 to £1.35 per square foot.

Stamping mats, which create the desired patterns on the wet concrete, add to the cost. Renting these mats generally costs between $100 to $200 per day, or £75 to £150. If you decide to purchase them, the price can range from $1,500 to $3,000, or £1,150 to £2,300, depending on their complexity and quality.

Colourants are another significant expense, with two main types used: integral colour and colour hardener. Integral colour, mixed into the concrete before pouring, typically costs between $40 and $50 per bag, equivalent to £30 to £40, with one bag covering about 1 cubic meter of concrete. Colour hardener, applied to the surface, costs about $60 to $70 per 60-pound bucket, or £45 to £55, with one bucket covering approximately 100 square feet.

Release agents, necessary to prevent the stamping mats from sticking to the concrete, come in powdered and liquid forms. Powdered release agents cost around $25 to $30 per 30-pound bucket, or £20 to £25, covering approximately 200 square feet. Liquid release agents are generally priced at $80 to $100 for a 5-gallon bucket, or £60 to £75, which covers about 600 square feet.

Additional materials include rebar or mesh for reinforcement, control joints to prevent cracking, and various tools needed for the application. Rebar typically costs about $0.75 to $1.00 per linear foot, or £0.60 to £0.75, while mesh costs around $0.10 to $0.20 per square foot, or £0.08 to £0.15.

For a 200-square-foot patio, the material costs can add up. The concrete itself would cost between $240 to $360, or £180 to £270. Renting stamping mats would add another $100 to $200, or £75 to £150. Integral colour might cost around $80 to $100, or £60 to £80, while colour hardener could be another $120 to $140, or £90 to £110. Release agents might add $25 to $50, or £20 to £40, and rebar or mesh would cost about $15 to $40, or £12 to £30.

Cost of labour for a stamped concrete patio

For a basic installation of a stamped concrete patio, labour costs generally range from £30 to £50 per hour, which is approximately $40 to $65 per hour. For a small to medium-sized patio, the total time required might span one to two days. This means you could expect to pay between £240 to £800, or $320 to $1,040, for the labour alone for a straightforward project.

More complex projects that involve intricate patterns, multiple colors, or custom designs will require more time and expertise. These projects often involve additional steps, such as detailed handwork, extra layering of colors, and precise stamping techniques. For such projects, labour costs can rise to about £50 to £80 per hour, which equates to $65 to $100 per hour. If the project takes several days to a week, the total labour cost can range from £1,200 to £3,200, or $1,600 to $4,000.

In addition to the hourly rate, some contractors might charge a flat rate for specific tasks within the project. For example, preparing the site, which includes removing old materials, leveling the ground, and setting up forms, might have a fixed cost. This preparation is crucial for ensuring the quality and durability of the finished patio.

Cost of sealing the stamped concrete

Sealers are essential for maintaining the longevity and aesthetics of a stamped concrete patio. They protect the surface from moisture, stains, and UV damage, and can also enhance the color and shine of the concrete. The cost of sealers typically ranges from $0.25 to $0.50 per square foot (£0.20 to £0.40 per square foot). For a 200-square-foot patio, this translates to a total cost of $50 to $100, or £40 to £80, for the sealer alone.

There are different types of sealers to choose from, each with its own cost implications. Acrylic sealers are commonly used for stamped concrete patios because they are affordable and provide good protection. These sealers generally cost between $30 to $60 per gallon (£25 to £50 per gallon), with one gallon covering approximately 200 to 300 square feet. This means you might need one to two gallons for a 200-square-foot patio, costing between $30 to $120 (£25 to £100).

Epoxy and polyurethane sealers are more expensive but offer superior protection and durability. These sealers can cost anywhere from $50 to $100 per gallon (£40 to £80 per gallon). Given their higher cost, they are typically used for busy areas or projects requiring maximum durability. For a 200-square-foot patio, using epoxy or polyurethane sealers could cost between $100 and $200 (£80 to £160).

In addition to the sealer, other finishing touches might include antislip additives, which are mixed with the sealer to enhance traction. These additives are especially useful for outdoor patios that may get wet. Antislip additives generally cost around $10 to $20 (£8 to £15) per packet, with one packet sufficient for a gallon of sealer.
