At DeAndrea Sawing and Coring, we also provide floor grinding and polishing services. Most commonly, concrete grinding is used to level out sections of concrete or asphalt that are uneven due to ground movement or construction. This approach can be a cost-effective way to make surfaces safe without the expense of ripping out concrete and re-pouring. We provide this type of grinding for everything from walkways to large slabs.
Another common use of floor grinding is surface restoration and resurfacing. Our grinding service can remove old paint, adhesives and residue. With our powerful grinding equipment, we can quickly get a surface ready for resurfacing, saving you time and money.
Polishing concrete in principle is pretty straight forward – taking a rough, porous concrete surface and polishing it to a smooth finish. However, there are several factors to be considered, and several process steps that need to be accomplished in order to achieve the desired final finish.
Aggregate exposure: If some level of aggregate exposure is desired, this needs to be specified and agreed to before starting work. Polishing can be done either with or without aggregate exposure – if aggregate exposure is desired, diamond grinding is required before starting the polishing process.
Finished Gloss: The surface is polished in successive steps, usually starting with 50 grit and ending at 400, 800, 1500, or even 3000 grit. A higher level of polish translates into a higher finished gloss level. Along with aggregate exposure, this needs to be specified and agreed to before starting work.
During the polishing process, a densifier is added to harden the concrete. This helps prevent surface damage and provides a longer service life.
Dyes/Stains: Color can be added to the floor if desired.
Sealing: A clear sealer is applied as the last step in the polishing process.
Polished concrete floors are a great option to bring life and luster to concrete floors. It also assists in sealing the concrete from water, oil and other foreign substances. When complete, polished concrete floors are a fantastic, attractive and low maintenance option as well as adds a protective hardener on the surface of the concrete for excellent durability and shine. Additionally, our polishing process is virtually dust free and slurry free.
