Finishing concrete indoors involves several steps to achieve a smooth, durable surface. This process requires careful preparation, the right tools, and attention to detail to ensure a professional result.
What Are the Steps to Finish Concrete Indoors?
Finishing concrete indoors is a meticulous process that involves preparing the surface, pouring the concrete, and applying finishing techniques for a smooth and polished look. Follow these steps for a successful indoor concrete finish:
-
Prepare the Surface
- Clean the area thoroughly, removing any debris, dust, or previous flooring materials.
- Ensure the subfloor is level and stable to prevent cracks or uneven surfaces in the finished concrete.
- Use a moisture barrier if necessary to protect against dampness.
-
Pour the Concrete
- Mix the concrete according to the manufacturer’s instructions, ensuring consistency.
- Pour the concrete evenly across the designated area, starting from the farthest corner and working towards the exit.
- Use a screed board to level the concrete, moving it back and forth to remove excess material and fill low spots.
-
Apply the Initial Finish
- Once the concrete is level, use a bull float to smooth the surface and push down any aggregate.
- Allow the concrete to set until the surface sheen disappears, indicating it’s ready for further finishing.
-
Trowel the Surface
- Use a steel trowel for a smooth finish, working in circular motions to achieve the desired texture.
- For a polished look, repeat the troweling process as the concrete continues to harden.
-
Cure the Concrete
- Cover the finished surface with a curing compound or plastic sheeting to retain moisture.
- Allow the concrete to cure for at least 7 days, keeping it moist to prevent cracking.
-
Apply Sealer (Optional)
- Once cured, apply a concrete sealer to protect the surface and enhance its appearance.
- Choose a sealer based on the desired finish—matte, satin, or glossy.
