How deep can a concrete grinder go?
The key to their versatility are the grinding attachments, which are available in a variety of types and grits to suit different applications. Because grinders use rotary action rather than impact to remove material, the depth of material removal is limited to about 1/8 inch, depending on the type of attachment used.
Can you grind down a concrete slab?
If you have an uneven concrete slab, you could replace it or cover it with leveling compound. But consider grinding it instead. Powerful grinding equipment is available at rental centers that cater to contractors. Grinding down leftover thin-set or other hard coatings.
Is grinding concrete dangerous?
Grinding and polishing of concrete will release the dangerous silica-bearing dust in to air, exposing construction workers and others. Breathing the silica dust can result in dangerous, irreversible, untreatable diseases, including silicosis and lung cancer (that’s the tragedy).
How do you remove a hump from a concrete floor?
There are a couple of ways:
- Grind the hump with a concrete grinder as long as it’s not too high and the slab is thick enough to be structurally sound after grinding.
- Fill around the hump with self-leveling compound.
- Sawcut around the offending hump and remove it.
Can I grind concrete with an angle grinder?
An angle grinder can be used to level, smooth and polish concrete by grinding it down. They can also be used to remove paint and floor adhesives. To grind concrete with a angle grinder you need a diamond cup wheel, a dust shroud attachment, and a vacuum cleaner.
Why do you grind concrete?
Grinding concrete removes all imperfections and inconsistencies in the concrete, resulting in a smooth and usable surface. Old and damaged concrete surfaces can be restored to their former glory and used for years and years to come.

How do you sand a concrete floor by hand?
Attach 180-grit sandpaper, which is a fine grit, to a pole sander, hand sander or floor sander. Put on a respirator, and sand the entire surface of the floor lightly. When the sheen is off the surface, scuff sanding is complete.
Should you wear a mask when mixing cement?
It means that if you work with materials that contain silica and you work in an area where silica can become airborne – due to concrete cutting, grinding, coring, stoning, cement mixing and sweeping, or sandblasting – you need to wear a respirator.
Is grinding metal bad for your lungs?
Those exposed to metal dust may be at a higher risk of developing chronic lung conditions. Prolonged exposure to metal dust like steel, iron and cobalt can result in lung conditions such as siderosis and black lung.
Can concrete dust cause cancer?
Exposure to silica dust can lead to the development of lung cancer, silicosis (an irreversible scarring and stiffening of the lungs), kidney disease and chronic obstructive pulmonary disease. It is estimated that 230 people develop lung cancer each year as a result of past exposure to silica dust at work.
Can you smooth out concrete after it dries?
How do you smooth concrete after it dries? Sand the Surface and Wash the Concrete Finish by fine-tuning with light sandpaper, until the surface is perfectly smooth. We recommend using a hand planer to smooth and compact the surface.
How do you remove the top layer of concrete?
The standard way to remove the top layer of concrete from concrete is via shot blasting. This might work for you. Obviously it depends on the relative hardness and shot resistance of the spilled concrete and the underlying brick. Since the concrete is presumably quite young, I think the brick wins.
