How Do I Clean My Concrete Floor After Grinding?

Rule number one when grinding concrete floors is to make sure you have a good dust collection strategy. If you don’t, be prepared for grey baby powder all over EVERYTHING!

The good news is that if you’re taking on a concrete grinding project, there are excellent products out there which make short work of collecting and disposing of all the dust. The trick is to hire your concrete equipment from seasoned professionals who can advise you on the best product for the job and who can guide you through the whole process.

Although there are two methods for grinding floors, ie wet and dry, the growing trend is towards dry grinding as it’s faster and more convenient and there’s no messy slurry to deal with. What’s more, if you choose the wet grinding option, you’ll have to wait at least 24 hours (after you’ve endured the tedious slurry clean-up) for the concrete floor to dry.

Dry grinding on the other hand allows you to continue with your project once the grinding is over, but the process does generate a significant amount of dust so quality dust-control equipment is crucial.You also need to be able to see the surface when you’re grinding (for example, to see if your scratch pattern is right or the level of sheen is correct etc), so you need to keep the dust from settling on the floor.

Any good concrete equipment hire company will be able to supply high-performance vacuums which can be attached to the grinders for dust-controlled grinders. The grinders should also be fitted with dust shrouds.

Here are some tips on cleaning your concrete floor after grinding and choosing a vacuum attachment for your concrete grinder:

Household vacuums aren’t suitable. 
The filtration system on a domestic vacuum cleaner is probably not going to be strong enough to handle the amount and the type of dust and you run the risk of dust getting into the motor and damaging it. So it’s best to leave your household one in the cupboard and get yourself an industrial vacuum — available in various sizes and capacities from lightweight, handheld models to large, powerful ones for big commercial projects.

A HEPA filter system is important. 
Airborne dust particles are potentially harmful, so it is essential to have a professional-grade dust collection system to maintain air quality. HEPA-type (high efficiency particulate air) filters are the Rolls Royce when it comes to vacuums, but more and more people are insisting on these models because of their superior particulate filtration.

Choose a vacuum with a filter housing that’s easy to access 
Before you hire any concrete equipment, check how easy it is to change the filters of the vacuum and how often they would need to be changed. Also ask whether the vacuums use a bag system which makes waste disposal convenient and easy.

Airflow rates are important 
You want to make sure your floor is as clean as possible after grinding, so ask the suppliers about the airflow rate of the dust collector. The higher the rating, the more efficient the dust collection will be.
