STI Polishing & Concrete Care — FAQs
Find answers about this STI collection and choosing compatible products.
No. Each diamond system has its own sequence and operating instructions. EGT is presented as a dry process; review the CLC listing for its specified wet and dry stages.
Start with the surface material, the current condition, the desired finish and your machine. Confirm the pad size, grit sequence, connection and wet or dry requirements.
No. Sealer, slurry solidifier and cleaning products serve different purposes. Use the product instructions to choose the correct item and application method.
Match the attachment to your machine and the polishing pad or diamond tool you plan to use. Check the listed dimensions, mounting connection and compatible equipment. Metal adapters, resin inserts, spacers and pad drivers should be selected for the specific setup rather than by appearance alone.
Follow the sequence specified for your selected polishing system. Choose the starting stage for the floor condition and inspect the result before moving on. Test a small area first, and use the manufacturer’s instructions to confirm each stage and its wet or dry requirements.
Check the contents of the individual product listing. This collection includes polishing systems, individual pads, adapters and floor treatments, so do not assume that a compatible holder or treatment is included with the item you select. Review package quantities and required accessories before ordering.
