Concrete Pouring Guide

1

Prepare Base & Isolate | Compact subgrade, add 4" damp sand. Place ½" felt between new slab and existing structures.

2

Pour, Screed & Tamp | Pour and level the concrete. Use a roller-bug to push rocks down and bring cream up.

3

Float Using A Wood Bull Float | Use wood only at this stage. It keeps surface pores open to let bleed water escape.

4

Cut Control Joints | Cut grooves ¼ the depth of the slab (e.g., 1" deep for a 4" slab) to control cracking.

5

Finish with a Metal Trowel | Wait for all bleed water to evaporate before using metal trowels.

6

Spray Cure | Apply a curing compound immediately after finishing to prevent rapid drying.
