What can be done with the renovation of many old concrete floors?
Do I need to remove the coating on the ground? What coating is it? How thick is the coating and how to do it?
The refurbishment of epoxy floor requires the selection of metal abrasive blocks according to the thickness of the coating.
For example: Choose One PCD abrasive pads one piece round diamond for making concrete grinding machine for thick coating ; Medium-thick coating options (1/4 PCD Segment Pad for Epoxy Removal Floor) ; thin coating options (30# Plug in Diamonds Grinding Pads ).
The refurbishment treatment of epoxy floor requires the selection of polishing pads according to the thickness of the coating.
1. The PCD grinding disc is a shovel-type tool, which is designed to remove the coating from the side instead of from the top.
2. Don't spend too much time in the same place when removing the coating, just remove 70-80% of the coating and clean it up, and remove the rest with a 30# metal polishing pad.
3. Pay attention to the direction of the PCD cutter head when installing. When grinding, keep half of the machine on the coating and the other half on the concrete. This method can keep the PCD grinding discs sharp.
4. The thin coating applied by spraying, brushing or rolling can be removed with 30# diamond polishing pad, and sharper 20# diamond polishing pad is also available.
