Fill and Level Cracks

What happens here

The video visually demonstrates the next stage: filling a previously chased crack. A person is shown applying a dark-colored polyurea filler into the widened crack using a trowel, spreading it evenly and smoothing it over the surface. The presenter elaborates on this process, stating that after widening, cracks should first be filled with sand, then a polyurea filler is poured in, troweled smooth, and subsequently ground flush with the concrete surface. This multi-step filling and grinding ensures a perfectly level and integrated repair.

Goal: Properly fill and level widened cracks and saw cuts in the concrete.
