How To Resurface Concrete Floor In Basement

Resurfacing a concrete floor in the basement is a practical and cost-effective way to revitalize the space, providing a fresh and durable surface. Before starting the resurfacing process, it’s crucial to assess the condition of the existing concrete. Any cracks, holes, or imperfections should be repaired using a concrete patch or filler. Once the surface is smooth and level, thoroughly clean the floor to remove any dirt, dust, or contaminants. For better adhesion, consider etching the surface with a concrete etching solution, which opens up the pores of the concrete to allow the resurfacing material to bond more effectively.

The next step in resurfacing a concrete floor in the basement involves applying a concrete overlay or resurfacing mix. These materials are typically polymer-modified, providing enhanced durability and flexibility. Mix the resurfacing material according to the manufacturer’s instructions, and apply it to the floor using a trowel or a long-handled squeegee. Work in small sections, ensuring an even and consistent thickness of the overlay. Consider using a concrete stamp or stencil if a decorative pattern or texture is desired. Allow the resurfacing material to cure thoroughly, following the recommended drying times before walking or placing furniture on the newly resurfaced floor.

How To Resurface Concrete Floor In Basement

The basement is a place of many activities. Whether it is used as a workshop, storage space, or recreation room, the flooring is an important factor in the overall look and feel of the area. If your basement floor has seen better days, there are several options for resurfacing it. Here is a guide to help you understand how to resurface concrete floor in your basement.


Before you start any resurfacing project, it is important to prepare the surface. This includes cleaning and repairing any damage that may be present. Make sure to use a degreaser to remove any oil or grease that may have accumulated on the floor. If there are cracks or holes, they should be filled using a concrete patching compound and allowed to dry thoroughly before proceeding.

Materials Needed

Once the surface has been prepared, the materials needed for resurfacing will need to be gathered. Depending on the type of finish desired, these may include sealer, primer, concrete resurfacer, trowel, roller, and edger. If you are using an acrylic sealer or epoxy coating, you will also need a squeegee and brush. Additionally, you will need safety gear such as gloves, goggles, and a respirator mask if you are using chemicals during the process.

Applying Resurfacer

Once all of the materials have been gathered and the surface is clean and dry, it is time to begin applying the resurfacer. Start by pouring some of the resurfacer onto the surface and spread it evenly with a trowel or squeegee. Use a roller to work it into any cracks and crevices that may be present. Finally, use an edger to smooth out the edges around any walls or other surfaces that adjoin the concrete floor. Let the resurfacer dry completely before proceeding to the next step.

Finishing Touches

After the resurfacer has dried completely, it is time to add any finishing touches that may be desired. This can include applying an acrylic sealer or epoxy coating for added protection and shine. For best results, apply two coats of sealer with a brush or squeegee. Allow each coat to dry thoroughly before applying the next one. Once all of the coats are applied and dry, your resurfaced basement floor is ready for use!


Q1: How long does it take for concrete resurfacer to dry?
A1: The drying time will depend on several factors such as humidity levels and temperature in the room but generally it can take anywhere from 12-24 hours for concrete resurfacer to dry completely.

Q2: Is it necessary to use an edger when resurfacing?
A2: Yes, using an edger will help create a smooth transition between different surfaces such as walls and floors so using one is recommended when resurfacing concrete floors in basements.

Q3: How often should I reseal my basement floor?
A3: The frequency of resealing will depend on how much traffic your basement gets but generally it should be done every 2-3 years in order to keep it looking its best.
