“Which one’s better; wet or dry concrete grinding?” This question is often asked by people looking to upgrade their flooring. The truth is that it depends on a lot of factors, circumstances, and, to an extent, personal preferences. Here at Concrete Grinding Concepts, we use a balance of both methods depending on each case. Let’s find out more.

Wet Concrete Grinding

If you think it’s called “wet concrete grinding” because water is involved somehow, you’re absolutely right. Wet concrete grinding and polishing were developed long before the dry grinding method; so, it’s natural for contractors to opt for this method – particularly in areas with an abundance of water supply.

Pros of Wet Concrete Grinding

The main role of water here is to cool down the diamond tooling and also provide lubrication to reduce friction. Without this lubrication, there is an increased risk of excessive heat generation (from the friction), which will melt the epoxy resin and glaze over the tooling. You don’t want that. So, in a way, wet concrete grinding extends the life of your tooling.

Additionally, a great deal of concrete grinding contractors prefer this method not just because of familiarity but also because water reduces the dust particles inhaled by the operator. Dust particles containing Silica can be quite toxic, putting the person at more risk of developing silicosis – a condition that leaves scar tissue in the lungs.

As great as it is, wet concrete grinding also has its setbacks. Let’s delve into a few.

Cons of Wet Concrete Grinding

It uses a lot of water, thus causing wastage and aggravating the global water crisis. Unless it is entirely necessary dry concrete grinding is much better for the environment than wet concrete grinding.

Wet grinding leaves slurry – a mixture of cooling water and concrete fines. It takes a lot of time to clean the slurry, and safely disposing of it without negatively impacting the environment is a significant challenge.

Wet grinding just doesn’t give you that smooth, shiny appearance that dry grinding does. If you’re going for a decorative concrete finish, wet grinding may not be the most ideal.

Dry Concrete Grinding

Technological progress has resolved one of the greatest setbacks of dry concrete grinding; dust exposure. Newer models come already fitted with dust extraction systems and filters to minimize dust exposure to the operator and the environment. This method simultaneously grinds and cleans the area and, in the process leaving behind a surface that’s ready to be polished.

Pros of Dry Concrete Grinding

It is more environment-friendly since it filters and collects dust particles and does not

leave slurry.

Speaking of slurry, the lack of it in this method means that you get to save much time in the clean-up process.

It gives a far better shine and finishes compared to wet concrete grinding.

Cons of Dry Concrete Grinding

It may not be the most ideal when dealing with very hard concrete. In such a case, you are advised to start with the wet grinding method and then switch to a dry grinding method afterward.

The dust extraction system makes the equipment a little more expensive.

Ultimately, the choice between these two methods will largely be driven by personal preferences, budget, time necessity. Bad flooring can ruin the appearance of the entire room – regardless of how much effort was put into it. Do not risk having your floors done by inexperienced people.
