(1) You may step on fresh concrete two days after it has been poured, but do not drag anything (especially your feet) on it. Fresh concrete can very easily be scuffed. (2) Heavy objects (such as patio furniture or planters) can safely be placed on fresh concrete in two to three days. (3) Do not use deicers on fresh concrete for at least two years. It will cause new concrete surfaces to spall (flake into little pieces). Actually, no deicers are safe for concrete. We advise use of sand (without salt) or kitty litter to provide traction on these surfaces in lieu of deicers. (4) If your new concrete work is done in the summer, we recommend hosing down the surface at least once a week through August or September (when daytime temperatures are 80 degrees or more) the first year. This will keep the concrete moist, giving it greater strength. Believe it or not, concrete hardens better under water!
