How to make concrete slabs smooth?

  • Smoothness is a must for polishing a concrete floor. It doesn’t matter what kind of style you’re going for; a smooth surface is essential.

  • It is possible to level a sloping concrete floor by applying self-leveling cement to the surface. To achieve a smooth finish, Ardex or other self-leveling cementitious mixes may be mixed, poured, and then sanded much like conventional concrete.
  • Once the concrete has dried and hardened to your satisfaction, it’s time to apply the final coat. Most of the time, a sealer isn’t necessary to get the desired sheen. With a good polish, it’s the sealer.
  • Mechanical polishing or chemical polishing are the two most common methods for finishing concrete.
  • Mechanical polishing is the best option if you’re looking for a shiny finish with the least amount of work.

  • Depending on the grit you apply, you’ll get a different gloss on your flooring. The best is to use a finer abrasive grit. The finer the finish, the higher the grit number you utilize. 800, 1,500, and 3,000 are common numbers.

  • Aluminum strips or a flat board drawn over the wet concrete may be used as the screeds. It is a huge trowel with a long, thin strip and one or two handles that can cover a vast area.
  • As a first step, use a screed board to press over the concrete’s surface and level it. As well as removing any extra concrete, the screed will also aid to plug any holes in the surface. If you want to smooth things out even more, use your darby.
  • In order to avoid leaving any defects on the surface, it is advisable to move the darby in an arc-like pattern while keeping it level.
  • Once the water has risen to the surface, you may begin the following stage in the process of smoothing out the concrete. 
  • Allow the concrete to cure once you’ve finished all of your finishing tasks. The polishing procedure may begin after the resin has hardened.

What is the best way to achieve a smooth finish on concrete slabs?

For concrete to have a great sheen, it has to be polished and polished thoroughly, not only with a single substance or sealer. When it comes to getting a mirror-like finish, mechanical polishing is the most efficient method.

Diamond polishing is now widely accessible to the general public, and it is used in public settings all around the world. In places like malls and airports, you may find floors that have been polished with diamonds. 

It’s presently the most preferred approach to get a shiny surface since it’s long-lasting and low-cost to maintain.

Using industrial diamonds, diamond polishing is a mechanical technique that may be used to smooth, grind, and polish any surface. Instead of using sealant, mechanical polish uses the concrete itself to provide a shiny surface that lasts.

Concrete polishing is a multi-step process using as many as nine separate grinding equipment. There are a number of various degrees of shine that you may attain, depending on your preference.

Depending on the required shine, you may choose between abrasives with grits of 800, 1500, and 3000. Finishing with finer grits results in a more polished surface.

The mechanical polishing of floors is believed to be very sustainable, durable, and free of toxic chemicals or solvents of any kind. The good news is that this technique of polishing may be used on both fresh and aged concrete.

Should I make garage concrete smooth?

No, you should not get a smooth finish for your garage concrete. 

The concrete garage floor should not be polished or sanded to a glossy finish since it is not durable, particularly in northern climes, to chemicals and salts. If you have water, ice, or snow on your shoes or in your car, you’re at much more risk because of the slick conditions. 

For garage concrete flooring, shiny smooth concrete may appear good, but it isn’t the ideal option. Because we live in a northern region and our new sparkling garage floor quickly became a source of irritation as winter set in, there are always exceptions to any rule. 

When it was wet and covered with snow, it was simply too dangerous.

Why does the finishing and smoothing of concrete matter?

Concrete’s texture and long-term durability are influenced by its finish. Concrete finishing is a personal choice, but the placement of the slab and what you want to use it for will play a big role in your decision.

The slip resistance of exterior concrete is generally achieved by the use of a texture, but internal concrete must be durable while still being flat and smooth. Concrete that will be covered with a floor cover, such as carpet, does not need to be absolutely smooth to function well.

What are the considerations to get a smooth finish on concrete?

  • Working with concrete necessitates that the finished project has a smooth and uniform surface. Despite the fact that this seems to be an obvious and self-explanatory truth, many individuals lack the necessary information to ensure that it becomes a reality. 
  • With the right equipment and a few insider techniques, you can have perfectly smooth concrete surfaces in no time. The initial phase in the procedure is to screed and darby the surface area soon after the cement has been laid down. 
  • A real screed is suggested for screeding, however it may be done with any tool that has the properties of a 2 x 4 board. Work begins with screeding, which is a technique of flattening and condensing the surface, while also making it easier to pour concrete.
  • After you’ve leveled the cement, use a darby to sweep the surface and fill up any minor holes or screeding marks. Overworking the surface will result in a weak surface, so use caution.
  • After smoothing the surface with a darby, you’ll see water rise to the top where it will settle. However, you should wait until it has dried before carrying on. It’s common for this to happen. In the long run, the surface will be weaker if you don’t start the procedure. 
  • Press your gloved thumb on the cement to determine whether the bleeding has stopped. A quarter-inch imprint is all you need to get started. Edgers may be used to trace the perimeter of the slab and crush the corners after the slab has been prepared.

Conclusion
