DON’T SKIP CONTROL JOINTS IN CONCRETE SLABS:
The goal of all concrete installation is to produce a high-quality product that resists cracking.
While curing concrete will go a long way toward strengthening the finished project, many concrete slabs will crack anyway — despite all precautions
DON’T SUBJECT NEW CONCRETE TO EXCESSIVE WEIGHT:
Although concrete will harden soon after pouring, it’s still susceptible to damage from weight during the first four weeks.
Wait at least 24 hours before allowing foot traffic, including pets, on a newly poured sidewalk or slab, and don’t drive a vehicle on a new driveway for at least 10 days.
DON’T LET NEW CONCRETE GET TOO COLD:
The best time to pour concrete is when temperatures are expected to remain above 10 degrees for five to seven days, but plans can go awry with the arrival of an unexpected cold front.
When that happens, the importance shifts from keeping the concrete damp to keeping it warm enough that the chemical hardening process is not interrupted.
DON’T PAINT OR STAIN CONCRETE IN THE FIRST MONTH :
Any paint or stain applied to young concrete while it’s still hardening can be negatively affected by residual moisture or the changing chemical content in the concrete. It takes about a month for all of the water to get used up in the hydration process.
Brush on paint too soon while moisture is still rising to the surface, and it can put pressure underneath the hard barrier of paint, causing it to peel away or break the bond.
