1. The concrete curb does not need to be sprayed or misted with water.
2. Keep pets, children, adults and objects away from the curb for at least 24 hours. It will be "hard" to the touch at this point, but will still need a few days to get completely hard.
3. Sod laying, sprinkler work and landscape work can be started 24 hours after installation; however, caution must be taken as shovels, picks and wheelbarrows can damage the curb for several days while it is fully curing.
4. If wheelbarrows are used for hauling rock over the curb, put a mound of dirt over it (6" deep) or build a ramp over the curb to keep the weight from cracking it. Never allow a tractor or truck to run over the curb.
5. If it begins to rain within 6 hours after we leave the job, try to cover the curb with plastic where run-off from the roof will land directly on the curb. Down spouts should be redirected for the first 24 hours to avoid direct water flow against the curb. Make sure sprinkler systems do not come on for at least 24 hours. Check that your neighbor’s sprinklers will not compromise your curbing during this time. Irrigation, back wash from pool, condensate lines, or rain can damage the curb during the first 24 hours.
6. Efflorescence (white powder substance) can appear on occasion and does not look good on curbing. It is generated from water sprinkling systems and can also appear after a rainstorm. The intensity of the efflorescence varies depending upon the type (hardness) of water and volume of water that gets on the curb. Check your sprinkler heads while the system is on and try to adjust them to minimize the amount of water spraying directly on the curb. If you have just planted sod and are watering frequently, efflorescence may appear more readily. Be patient, wait for your lawn to get established and clean the curb after it dries. A solution of 50/50 vinegar and water with a light brushing will remove the efflorescence. You may have to do this a few times; eventually, the efflorescence should go away.
7. Occasionally curbing with color in it may look "splotchy" for a few days while it is curing. This will go away as it cures and is not to be confused with efflorescence. The surface color should be reasonably stable within a week however, concrete takes 28 days to completely cure.
8. Cracking - Concrete curbing like any other type of concrete can and will crack. We try to control the cracking with expansion joints. If cracking does occur, it should be in the expansion joint. We experience very little cracking in our products.
9. Your curbing has a one-year warranty against defects in materials and workmanship. It will be replaced at no charge if the defect is caused by the materials we use or the way it was installed by our workmen.
