Working with ready-mix concrete is relatively easy, and the number of bags to purchase depends on the scope of the project. To use, simply pour the ready mix into a large container such as a wheelbarrow, add water, and stir to mix well. The keys to getting the mixture to the right consistency for application are adding a measured amount of water and not using a hose. For the best results, mix the concrete for a few minutes using a garden hoe, and wait for it to achieve a good consistency. Add more water a little at a time to avoid a soupy mixture.
Soupy concrete is 50 percent weaker than properly mixed concrete and prone to cracking, so it's important to be patient when mixing. Wear protective gear such as a dust mask, goggles and heavy gloves while working with ready-mix concrete.
