Prepping concrete is the process by which you prepare an area of concrete before beginning a project. This might involve removing stains, getting rid of old paint, or even just cleaning the surface. Prepping concrete before a project is a key to making the most of your investment. If you don’t take the time to prep your concrete, it can lead to stains and ugly discoloration, which can create problems in the future. Concrete is porous and will absorb whatever touches it. That’s why it’s essential that you seal your concrete before starting a project on it. This article highlights why prepping concrete is important and what the process entails.

Why is Prepping Concrete Important?

When you prep concrete, you remove dirt, debris, and contaminants from the surface. This ensures your newly applied coating will adhere properly to the slab and last as long as possible. In addition, prepping concrete often includes grinding down any high spots or uneven areas. This allows for a better bond between the finished surface and the slab.
If you’re applying a coating over a new slab, it’s crucial that your contractor prepares the surface with proper curing procedures before applying a coating.

What Does Prepping Concrete Before a Project Involve?

Whether you’re putting in a new sidewalk or installing some pavers for your backyard patio, there are certain steps you should take to prep for your project. First assess the condition of the existing concrete. Look for cracks, spalling, or signs that it has been sealed. Deep cracks may not be able to be repaired with DIY products. You’ll need to use a professional service to fill them with new concrete. Lightly sanding away any loose aggregate will give you a smoother finish on your finished project and will help make sure your materials adhere properly. It also makes it easier to remove things like dirt, moss, and oil stains if they are present. Make sure everything is dry. Here is what to do:

Assessing the Condition of the Concrete Surface

Assessing the condition of the concrete surface is perhaps the most important step. Before you start any work on the concrete, it’s essential to evaluate its condition and make sure it’s repairable. If you’re unsure as to whether or not your concrete is in good enough condition, hire a professional contractor to check it out before you start repairing or painting it.

Cleaning the Concrete to Remove Contaminants

Cleaning the concrete properly is one of the most important steps in preparation. You can’t paint over dirt, so use a high-quality cleanser to remove oil, grease, rust, and other contaminants before you start your project.

Roughening Up a Smooth Concrete Surface

Roughening up a smooth concrete surface is one of the most effective ways to ensure that your paint has something to adhere to on a clean and dry surface. Using an etching solution designed for concrete will prepare your floor for painting by helping the paint bond with the concrete better.
