Gather Your Materials

The first thing that you will need to do before you start making your concrete patio smooth is to gather all the materials you will need for that. The list of these materials typically includes the following items:

  1. an epoxy resin duct tape
  2. a floor grinder
  3. a mop
  4. plastic sheeting
  5. a concrete sealer
  6. protective gear such as a face mask, goggles, earplugs, and rubber gloves
  7. a shop vac

Prepare the Area

Before you start turning your rough concrete into a smooth one, you need to get the area ready. That means that all the furniture and items should be removed from the concrete patio.

Anything that cannot be removed should be covered with plastic sheets. It will allow you to protect the items from being damaged and covered with concrete dust. Next, at this stage of the process you will also want to mop the concrete floor.

Mopping will help you remove any dust and debris.

After you are done with mopping, allow the floor to dry, and while you are waiting for it to dry fully, divide the floor into smaller zones so you can focus on smaller sections at a time.

Start Sanding

We recommend you start with either 30 grit or 60 grit sandpaper. Attach the sandpaper to your floor grinder and start sanding the concrete patio in one corner. Make vertical passes along the concrete patio floor, covering half of the previous pass with each pass.

If there are any bumps, go over them carefully in order to completely remove them.

Fill All the Cracks You Can Find

If your concrete patio happens to have any large cracks, they have to bi fixed with the help of the epoxy resin. You just need to make sure that the epoxy resin is smooth and then allow it to completely cure before moving on to the next step.

If there are no cracks on the surface of your patio, then you can skip this step and move on, following the instructions given below.

Continue Sanding

Yes, there is going to be a lot of sanding, as you can already see! So, if your concrete patio had any cracks and you had to fix them with the epoxy resin, you shouldn’t skip this step.

Once the epoxy resin is completely cured, continue sanding. You will want to start at the far corner where you finished, and then keep sanding until you end up where you started.

Keep on doing so until you have passed over the same area at last four times, with the second set of two passes seeing you working horizontally or side-to-side, as opposed to sanding in vertical lines.

Apply Concrete Sealer

After you are done with sanding, you can move on. And now it is time to apply a generous amount of concrete sealer to the area that has just been sanded. We recommend everyone follow the instructions on the label of the product and make sure that you give the concrete sealer enough time to dry.

Continue Sanding

After the sealer is applied and dried thoroughly, you will want to repeat a few of the previous steps. But before you proceed, make sure you switch the sandpaper in the grinder to either 80 grit or 120 grit.

Now you need to make vertical passes with the grinder, making sure to cover half of the last pass each time. Like this, you will smooth out bumps, then fill divots with epoxy, and allow them to dry.

Then you just need to continue sanding, starting in the far corner and working your way back. Keep on doing so until you have reached the starting point.

Clean the Floor and Continue

After you finish the sanding session, clean the floor with a mop and then allow it to dry. What you need to do now is to keep sanding, switching to progressively finer grit sandpaper until you reach around 1,500 grit or even finer.

All you have to do is keep cleaning and mopping the floor and then keep switching to finer sandpaper until you reach the ideal smoothness for your concrete patio. Once you have achieved the desired smoothness, you can give your concrete patio one last mopping and cleaning.

Like this, now you have a complete and detailed guide on how to make concrete smoother.

If you make sure that you follow all the steps we described precisely, without skipping any of them except for those that you don’t need (like fixing the cracks), you will be able to get a smooth concrete patio surface with minimal effort.

Seal It

Sealing can help extend the lifespan of your concrete surface and keep it looking good longer. There are different types of concrete sealers that can be used, for example, topical sealers that can be applied to the surface every few years in order to prevent staining and damage.

Remove Stains Immediately

Even if your concrete surface is sealed, you should still clean stains and spills from concrete as soon as they appear. Cleaning any dirt, spills, as well as other stains in time will help prevent any discoloration or staining from occurring. As a result, it will help your concrete look better.

Limit the Weight

Concrete is a very strong and durable material. However, residential concrete is not designed to hold extremely heavy materials. For example, your driveway might be perfectly fine with the weight of your car or bike, but it won’t handle heavy machinery or oversized vehicles!

So keep heavy machinery somewhere other than your driveway to extend the lifespan of your concrete.

Avoid the Wrong Chemicals

Using certain chemicals on your concrete can be harmful. For example, certain deicers can work through the sealer and harm the concrete surface! Fertilizers can also stain it, so be sure to remove any excess or spillage from your concrete right away. It’s also important that you use a cleaner specifically designed for concrete, as some household products may rather cause harm than good.

Well, this is the complete guide on how to make your concrete patio smoother if its surface is far from that state. No matter why the surface of your patio became harsh, with the help of these instructions, you will be able to fix it relatively easily.

Why relatively?

Well, because, as you could see, making concrete even and smooth takes some effort and time anyway. It is not something that can be done in a minute!

However, if you follow our recommendations precisely and don’t skip any of the important steps we mentioned, you can be sure that your concrete patio will become smooth again. Just make sure you use the protective gear for yourself and the correct tools for the concrete to smooth it out.
