How To Smooth Concrete After It Dries: Step-By-Step Guide

How To Smooth Concrete After It Dries.

Concrete is undoubtedly the most commonly used building material in the United States. Its use varies; everything from sidewalks to swimming pools and patios; it’s even used for home foundations!

But concrete can be a little tricky to work with, especially if you’re new to working with it. If you’ve ever poured concrete, you know that one of the most difficult aspects of finishing it is smoothing out the surface. 

In this article, you’ll find a step-by-step guide on removing imperfections and making your concrete smoother than ever.

How To Smooth Concrete After It Dries

To smooth concrete after it dries;

  • First, you need to clean the surface thoroughly with a broom, cleanser, and water.
  • Next, get rid of whatever flaws are on the surface.
  • Then repair the damaged areas with epoxy gel. 
  • Apply adherent to fill in the gaps. 
  • Remove any debris you find.
  • Then install a new layer of concrete. 
  • Afterward, sand the whole surface area and then wash the concrete.
  • And finally, to preserve the concrete, you must use finishing material such as sealant or epoxy.

Smoothing Concrete After It Dries Step-By-Step

The world’s most popular building material is concrete. 

Concrete is a mixture of sand, water, and cement. Water can greatly affect the concrete’s strength, durability, and workability. Other ingredients, such as gravel and stones, can also be added to the mix depending on what you want to achieve. 

A concrete surface becomes rough after it dries because the cement mix and aggregate particles dry and no longer move, making the surface hard. Here’s how you can smooth your concrete after it dries:

1. Clean the Concrete

Suppose you have a freshly paved concrete driveway or sidewalk, but it’s not smooth. The problem is typical in that there are still small particles of debris left-over from the construction process. 

You should make sure you remove all of the dust and dirt on the surface. You can brush the surface with a push broom to remove dust or dirt particles. 

Next, pour a pH-neutral cleanser on the concrete slab and rub it in. Next, pour a bucket of water over the floor. It would help if you used a squeegee after pouring the water; this will help you remove excess water.

Please wait until it dries off before working on it for the next procedure.

2. Get Rid Of Flaws And Imperfections On the concrete

When it’s poured and left to dry, concrete can have a variety of imperfections on its surface. Many are afraid that these imperfections will ruin their concrete, so they pour more concrete over them and hope for the best; this is not the best solution, though! 

The most important thing about finishing a concrete floor is to remove all imperfections on the surface. First, you need to use a putty knife to scrape away all loose concrete bits from the surface. Try a wire brush to smooth them out if you still see bumps or divots.

3. Patch Damaged Areas With Epoxy Gel

An application of epoxy gel will seal up small cracks and prevent further damage from happening. Epoxy Gel is a high-performance product for concrete restoration that is easy to use and provides long-lasting results.

4. Apply The Adherent

Once you’ve done that, you need to apply an adherent. The adherent will help fill gaps between concrete pieces and seal off a porous surface to prevent water seeping through the surface.

5. Remove Any Debris You Find 

The next step to solving your problem is to vacuum up all the debris and ensure there’s no speck left behind. Vacuum cleaners not only remove dirt; they also act as mini jackhammers and break up rocks.

You might also need a broom. The broom will help you loosen any dirt the vacuum cleaner may have left behind.

6. Install A New Layer Of Concrete.

The procedure of adding a new layer of concrete to a rough, non-smoothed surface may seem like a waste of time and money. After all, the only way to create a smooth surface is by smoothing it out with a trowel. 

Nevertheless, you can have a new, beautiful concrete slab for free. The best way to do this is by installing a self-leveling floor mixture over the top of the existing concrete; this will give it that sleek, professional look it deserves.

For small cracks, use a wet saw with a diamond blade. For larger cracks, use a trowel.

7. Sand The Whole Surface Area And Then Wash The Concrete. 

You can smooth the concrete after it dries by sanding the whole surface area and then washing the concrete. This process may take some time, but it will ensure a smooth and even surface.

The first step is to sand the entire surface area using a belt sander. Once you have finished, you should hose down the entire area, washing away any dust and releasing any remaining moisture. If you wish to speed up the sanding process, you can use a power washer.

8. Apply A Finishing Material to Protect the Concrete

Add a finishing material to the surface, such as paint, sealant, or epoxy. Experts recommend using thin coatings to avoid puddles. Allow a couple of hours before applying the second layer.

You apply a vitrified layer to concrete surfaces to protect them from damage and extend their lifespan. The process involves applying a liquid solution of sodium silicate and water. This solution is then fused to the concrete surface, creating a glassy layer.

The most common use for vitrified layers is to protect concrete from acid rain damage in the construction industry. It is also used on sidewalks and other pedestrian surfaces subject to wear and tear. 

How Do You Get A Glossy Finish On Concrete?

A glossy finish on concrete is a specific type that involves applying a sealant and then polishing the surface with a machine or by hand. Polishing the surface removes any imperfections and gives the concrete a smooth texture.

The surest way to give your concrete a glossy finish is to apply an acid etch first, which will make the surface more receptive to the sealant. Next, you’ll need to be sure to use acrylic-based sealants, which are specially formulated for this type of finish.

How Long Should You Wait To Smooth Concrete?

Most people assume that you need to put down a layer of concrete and wait to dry; this is not exactly the case. The drying process takes time, and you need to know how long you wait between steps.

 You want to wait at least a day before starting the trowel-down process; this will allow the concrete to harden and take shape. Depending on the weather conditions, it would be best to dry, anywhere from 1-3 days.

The wait time for concrete depends on the weather conditions and how long you’ve left the concrete to set. 

What Does It Mean to Smooth Concrete?

This is called concrete finishing. Concrete finishing is smoothing the surface of freshly laid concrete to provide a desired finish for the structure; this may involve grading, troweling, and coloring.

What Is Dry Grinding?

The process of grinding concrete without water is called dry grinding and is used to reduce the size of aggregate, remove fines from the mix, and increase the strength of the concrete.

Dry grinding is done by using a dry finisher with diamond tools. The dry finisher has a rotating drum that turns slowly and is pneumatically driven. This drum is mounted on an oscillating frame that oscillates horizontally to produce a shearing action.

The dry finisher removes fines and dust from the mix before being wet-mixed by the wet mixer machine. It also grinds coarse aggregate, which is needed to increase the strength of the concrete.

Dry grinding is a process that is best suited for small batches of concrete. The dry grind process is not a standardized method in the industry and is usually used for projects such as repair or patching. 

What Is The Best Mix For Concrete?

The best mix for concrete is 1 part cement, three parts sand, and five parts aggregate. Aggregate can be any material but is typically crushed gravel or limestone. 

The three components are combined to form a dry mixture, which is then added to water gradually and mixed into a slurry.

Conclusion

Few people are willing to spend the time and energy required to smooth a fresh concrete slab. The process is laborious and time-consuming, with lots of backbreaking work involved. It’s worth it, however, because it looks great and helps prevent future cracks.

This article has discussed how to smooth concrete after it dries, including how to prepare your tools and what steps you need to take. By using the steps and advice we’ve provided above, you can get a smooth finish on concrete that is worth admiring. 

Hopefully, you have found this guide useful.
