Fixing Cracks In Concrete SA simple, permanent repair for cracked concrete walls.
Concrete consists primarily of cement, sand, gravel and water.
As the water in the slurry evaporates, the remaining ingredients cure into a hard, monolithic slab. Unfortunately, the curing process causes the concrete to shrink slightly, often resulting in hairline cracks. Sometimes ugly is only skin deep. Getting under those layers of old paint might reveal a valuable piece of furniture. There's probably an old dresser, chair or table you've sequestered in a dark corner of your basement or attic that's covered with cracked and blistered paint.
