Finish by fine-tuning with light sandpaper, until the surface is perfectly smooth. We recommend using a hand planer to smooth and compact the surface. If the concrete dries a lot then we recommend that you add water to the surface, this will help you give it a good finish.
How to Smooth Dry Concrete?
Dry concrete is often rough and bumpy, making it difficult to level or smooth. Luckily, there are a few simple techniques you can use to smooth out dry concrete and get a nice, even surface.
The first step is to wet the concrete with a hose or a wet sponge. This will help to loosen up the surface and make it easier to work with.
Next, use a trowel or a putty knife to scrape off any high spots or bumps. You can also use a power sander to sand down the surface of the concrete.
Finally, use a damp sponge or cloth to smooth out the surface of the concrete. You may need to apply several coats of water to get a completely smooth surface.
Once the concrete is smooth, you can apply a sealer to protect it from weathering and stains.
