Request for sanity check ) Situation: planned shower 1000*1100 without hob on existing concrete slab. Was wondering if it makes sense in just grind the shower base in the slab, instead of removing a bigger part of the slab, pour a new concrete shower base and form the slopes of the shower base with screed.

There was a lot of aggregate and larger diameters, and this concrete compared to other slabs I have ground before was exceptionally durable and abrasion resistant. There was almost no edge chipping, and it took about 20 minutes of back and forth grinding just to do about four feet, about 5 times longer than similar joints.

What I hate: any project that involves grinding concrete. I had to mount something to a poured-concrete wall, the wall had some uneven bumps on it so I used an angle-grinder with a concrete-grinding disc to knock-down the high spots so the item would mount flush to the wall. Now, I have used an a...

What little I know about concrete is that you float the cement to the surface when finishing so it stands to reason you would be grinding it away.

If you want to make the face of it smooth/polished, then look on Amazon for concrete grinding cups. Multiple grits. With such a small area, an orbital sander and coarse to fine successions of sand paper would work. Wet/dry sand paper, as you will need to use water to sand in the final stages. Concrete sealer or paint would help.

Grinding/shaping sharp 'concrete' edges??? My drive is block paved and part of it is a few inches higher than the surrounding area. The paving blocks in this particular area are retained by a lengths of concrete edging. However, the outside edges of the concrete edging-strips are 90 degrees and are quite sharp as you'd imagine.

The manufacturer says this grinder can remove 1/32" over 350-500 feet per hour. Four-plus hours of grinding sounds like a bit of a slog, but if it turned out well, probably worth it. I got 'resurfacing' (grind, level, epoxy coat) estimates from $4.50 to $7.50 per square foot. Anyone have experience and advice about grinding concrete floors?

A old timer here said that grinding, sand blasting and almost any operation that tries to roughen the surface does just the opposite, especially on a microscopic level. I don't think that diamond grinding is the way to go. It might look more rough, but as far as the concrete molecules know (and they know), it's slick as snot.

I was wondering if anyone has tried grinding down that much concrete. Its about one inch at the furthest point and one foot by 12 feet, and the amount to be removed obviously gets less as it gets closer to the door. Any info appreciated. Those companies that towns use to do curb cuts might be able to handle cutting it.
