Newly laid concrete must cure for a specific period of time to achieve its full strength. Curing concrete consists of keeping it moist around the clock. A common method of curing concrete is to lay wet burlap or other fabrics on the moist concrete and to keep the burlap wet with a hose or sprinkler system. Properly curing the concrete will result in a harder surface and a more durable concrete slab.
Things You'll Need
- Burlap bags
- Garden hose
Soak the burlap bags in water. Flatten the bags out and lay them on the moist concrete in a single layer. Overlap all edges of the burlap by 2 inches to ensure no cracks form between the bags.
Spray the burlap bags with water from a garden hose to ensure they remain soaking wet. Set up a sprinkler along the edge of the concrete.
Turn on the sprinkler and keep it on continuously. Allowing the burlap to dry out and then wetting it again may damage the concrete slab.
Set up more than one sprinkler if you have a large area of burlap and the single sprinkler is not sufficient to keep all the fabric wet. Keep the burlap wet for seven days if your temperatures are around 70 degrees F. If you are in a cooler climate with temperatures closer to 50 degrees F, keep the burlap wet for nine days.
