This is how not to lay a concrete floor for diamond polishing. We recently undertook this project in London where a builder had laid a concrete floor supposedly in line with our strict specification; unfortunately this was not the case. As you can see from the photographs, this concrete floor in London was very poorly installed and required an excessive amount of remedial work (additional grinding, coarse filler, fine filler, hand edging)
It is important to note that when we supply our concrete requirements to our clients, it is to ensure they get the best floor they possibly can, adhering to our specification is critical.
Over a week we managed to produce an acceptable floor finish by carrying out additional grinding to high spots and rough uncompacted areas, application of a thick coarse filler (PROfill) and grouting with an aeration hole filler (PROgrout). Many of the holes where so large that we needed to allow extra time to ensure the products had fully hardened before smoothing off, so as not to drag the filler out.
After the coarse grinding, we honed the surface with our advanced ceramic tools to remove any coarse scratches from the concrete surface. Next our ultra sharp resin bonded diamond polishing pads were spun at high speed to polish the floor to a low gloss/satin finish.
During the diamond abrasive processing of this concrete floor we used our nano lithium silicate densifier to harden and seal the internal pores of the polished surface. Our PROhard densifier begins work immediately and continues to densify the crust for months to come.
Finally the surface was fully sealed with our guard coat PROguard and burnished to lock the guard into the concrete. PROguard is easily maintained with ph neutral cleaning products or maintenance cleaners like our gentle PROcare product.
We would have preferred to have applied one of our concrete overlay products to this floor, to produce a much more satisfying finish.
