How to Finish Concrete: 15 Steps (with Pictures) - wikiHow

8/10/2020 · Compress the concrete only if necessary. Many modern concrete mixes do not need to be compressed, or "tamped", before finishing, and tamping the wrong mix can weaken the slab. Confirm your decision with a professional before tamping. If you do decide to tamp, simply press the concrete down using any variety of tamping tool (hand, rolling, etc.). 3 Place a 2x4 across the concrete. Find the
