If you have no experience with concrete grinding, it might seem like a complicated task. There are so many aspects involved with the process, that it might seem overwhelming at first.
Fortunately, we prepared this guide to help you make the most of the task at hand. Here are 8-tips and tricks you need to know before you fire up the machine and get to work.
Use the Right Tools for the Job
The first step is to ensure that you’re using the right diamond tooling to cater for the bond hardness on the floor you want to grind. Using the right tooling has a tremendous effect on the outcome of the job, and using the wrong diamond tooling results in premature wear or glazing of the tool head.
Prepare the surface by tossing some sand onto the slab before you start grinding. The sand covers any sticky patches left on the surface of the floor, and it also helps to open up the diamond tips on the tool, providing extra abrasion.
Extend Blade Life
When using a multi-directional tool head, make sure you reverse the spinning action to prevent the tool head from clogging. This technique prevents inconsistent wear of the diamond tips, as well as scratching of the floor.
Stop Tool Head Glazing
If the diamond tool head becomes glazed, it reduces the efficacy of the machine. To prevent this from happening, move the grinder to an untouched area of the floor and start again.
The rough surface helps to open the diamonds, increasing the service life of the diamond blades. This technique is especially useful when grinding coatings or adhesives.
Soak the Slab
Before you start grinding, soak the slab with water. This tip helps increase the friction on the tool head, resulting in better operation.
The soak will also lower the surface temperature, extending the life of the abrasive pads. This tip is a must for anyone that’s working in a warm climate.
When you start grinding, run the dust collector at low speed. This strategy allows dust to collect under the tool head, increasing the abrasive qualities of the diamond blades.
This tip is also useful for helping to remove sticky adhesive from the floor. The dust collects on the adhesive, allowing the machine to rip it off with ease.
Use Other Tools for Scraping
Some jobs are more challenging than others. For example, concrete glue removal can reduce the service life of your diamond blades significantly. Using a ride-on floor scraper or shot blaster alongside your grinding machine can help increase the service life of the abrasive pads.
Select the Right Contractor
If you’re not doing the job yourself, then make sure you select a qualified and experienced contractor for the job.
Professional contractors will leave your concrete floor with a high-polish finish that makes your reception or lobby look fantastic. However, choosing the wrong contractor could end up with scratches on your floor, reducing the aesthetic appeal of the surface.
Always review the customer testimonials of the contractor you intend to use. Any seasoned contractor should provide you with plenty of references on request.
Floor Preparation and Concrete grinding is a skill. If it’s your first time using a concrete grinding machine, take it slow and make sure you use the right technique and tips mentioned in this article.
If you find yourself struggling, hire a professional to complete the job. It’s better to pay a few extra dollars for the work, rather than ending up with a damaged concrete floor that needs replacement.
