Concrete Polishing – What You Need to Know

There are two methods of polishing concrete: wet polishing and dry polishing. Each has advantages and disadvantages. In this article, we’ll discuss wet polishing, chemical dissolvers, sealers, and anti-slip additives. You can choose the method that works best for your project, polishing perth click.

Wet polishing

When you start your concrete polishing project, you’ll want to use the right tools. Professionals use specialized concrete polishing machines known as abrasive polishers, which spin an abrasive pad at high speeds. They can range in size, from a few hundred dollars to several thousand dollars.

One of the main disadvantages of wet polishing is the slurry it produces. The slurry can be dangerous for both workers and the environment. OSHA set new standards for silica exposure in 2017, and while silica dust is not a direct breathing hazard, it is a significant issue when performing concrete polishing jobs.

Chemical dissolvers

Chemical dissolvers for concrete polishing have different purposes. Some are used to remove staining, while others are used to produce a bright, shiny finish. They are commonly used in large-scale projects, while some are used for quality assurance. In either case, the chemical dissolvers should be water-based.

These chemicals are also used to remove moulds, which are created from concrete. Concrete polishing companies usually use a chemical dissolver that is designed for this purpose. Concrete polishing projects are much more productive if these chemicals are used during the early stages of the grind process.

Sealers

Sealers are applied to a concrete surface to make it more durable and resist water, oil, and grease. They also make concrete easier to clean and maintain. Sealers are typically applied by a professional. Some homeowners attempt to apply their own sealer, but it’s not recommended. To make sure the sealer is applied correctly, you should seek the help of a concrete contractor. These contractors may offer maintenance packages as well.

The first coat of sealer should be applied thinly. It should not puddle or form any thick spots. The second coat should be applied perpendicular to the first coat. It should be left for two to four hours to dry. Depending on the manufacturer, you can allow up to three days to fully cure the sealer.

Anti-slip additives

When used correctly, anti-slip additives for concrete polishing can make the difference between a slippery floor and a safe floor. Polished concrete is prone to slippage, especially when wet or icy. It can cause injury or accidents. The more polished or color-hardened the concrete surface is, the more slippery it will be. To improve its slip resistance, anti-slip paint, additives, or silica sand can be used.

Anti-slip additives are available as liquids or particles, and help to create a rougher surface so that shoes grip the floor better. They are most common in industrial settings, but they can be used in residential applications as well. The anti-slip additives can also improve the traction of epoxy-coated floors.

Cost

The cost of concrete polishing depends on several factors, including the amount of space to be polished, the sheen level desired, and any additional features such as staining. In general, polished concrete costs $3 to $12 per square foot. The more square footage you have, the lower the per square foot cost.

There are three basic types of polishing methods. Each gives a slightly different look and a variable life span. The simplest method is the grind and seal method, which involves grinding the concrete and then applying a sealer. This method is relatively inexpensive, but it limits the amount of customisation that you can get. A second option is mechanically polished concrete, which involves hardening and denitizing the concrete.
