About this Project

Finishing concrete is a specialized skill that you can't learn quickly. If the project is large, have someone on hand who knows finishing. If it's a small project and appearance isn't important, however, it's a good time to learn a new skill.

Timing is critical. If you start too soon, you'll weaken the surface. Start too late and the concrete will be unworkable. The waiting period depends on the weather and type of concrete. Start when the water sheen is gone from the surface and the concrete will carry foot pressure without sinking more than 1/4 inch.
