Wet vs Dry Concrete Grinding: Pros and Cons

 

Did you know there are two methods of concrete grinding? Wet or dry concrete grinding both present certain benefits. Here are some pros and cons for each method:

Wet Concrete Grinding

The oldest way of grinding and polishing concrete is the wet method. This method involves lubricating the diamond attachment with water, which leaves a slurry of water mixed with silica dust particles.

 

Pros

 

Significantly reduces the health risk of silica dust

One of the most significant benefits the wet method has over the dry method is its ability to remove the health risks associated with inhaling toxic dust particles like Silica dust. The flow of water from the grinding disc prevents dust from getting everywhere.

Extends the life of the machinery

Lubricating the diamond attachments with water keeps the grinder at a suitable temperature and reduces friction. This then increases the life of the grinder.

It’s been around for a long time

Many people have learnt to grind and polish concrete using the wet method, simply because it had been around longer than dry methods. This means there has been more time to refine the techniques.

 

Cons

 

Difficult clean-up process

The slurry left over from the wet method is difficult to dispose of efficiently and safely unless you are a professional concrete grinder who is aware of the regulations.

Slippery work surface

A wet surface can be a safety risk unless you have experience and the right equipment.

Not eco-friendly

This method can seem like a waste of water when there’s an alternative dry method and new technology can reduce the health risks associated with the dry grinding method.

Dry Concrete Grinding

Advancements in new technology has brought about dry grinding tools with a separate attachment to contain dust. This method is best left to certified and experienced professionals who can safely carry out the job who may use purpose built high filtration dust extraction units to remove residual dust.

 

Pros

 

Faster clean-up

Professionals such as Designer Floors use machinery with vacuum enabled waste management for more efficient waste removal. This means the cleaning occurs simultaneously as the concrete grinder is working. Additionally, the disposal of dust and debris can be done much quicker and safer than slurry.

Shinier sleeker finish

The dry concrete grinding method can produce a better shine the wet method cannot achieve.

Less downtime

Rather than waiting for the slurry to be cleaned up or the surface to dry, you can move straight onto the next step of the floor refurbishment.

 

Cons

 

Presents a danger to health

The main concern over the use of the dry method comes from the vast quantity of silica dust produced during the grinding process, which poses a serious health risk. Even if most of the dust is vacuumed, airborne dust lingering in ventilation systems can be hazardous. Inhalation of silica may cause respiratory illnesses including silicosis and lung cancer.

 

 

Concrete grinders often use both methods over the grinding and polishing process. As Husqvarna certified contractors, we only grind concrete under wet conditions. This is to get the best result, as well as lower health risks. Are you looking for concrete grinding or polished concrete? Designer Floors have got you covered.
