Business
Garage & Patio Epoxy Prep
Offer dust-controlled surface prep for epoxy/urethane coatings: remove laitance, open the concrete profile, and flatten high spots. The turbo cup’s aggressive removal speeds up throughput; pair with a dust shroud and HEPA vac. Bill per square foot with add-ons for crack chasing and edge work.
Tile Thinset Removal Service
After tile demo, grind off thinset and level the slab for new flooring. The balanced cup wheel reduces vibration for faster, flatter results. Market to homeowners, flippers, and installers needing quick turnarounds.
Sidewalk Trip-Hazard Mitigation
Grind lifted slab edges to ADA-compliant bevels and eliminate trip risks. Package as a mobile service for HOAs, commercial properties, and municipalities. Low equipment footprint and rapid job completion enable route-based pricing.
Concrete Countertop Refresh
Flatten, re-profile, and prep existing concrete countertops for resealing or micro-topping. The turbo-row wheel provides a smoother grind pattern that reduces follow-up sanding time. Upsell stain protection and annual maintenance plans.
Coating & Stucco Prep on Masonry
Provide surface preparation on block, brick, and stucco: remove paint drips, efflorescence, and weak surfaces to ensure proper adhesion of new coatings or skim coats. Market to painters and GC partners; charge by condition and access complexity.

Exposed-Aggregate Coffee Table
Cast a concrete tabletop, then use the 4 in. turbo cup to flatten, remove laitance, and expose aggregates for a terrazzo-like look. Follow up with finer grits/polishing pads to refine and seal. The balanced steel body helps minimize chatter on the large surface.
Geometric Concrete Wall Panels
Pour thin concrete panels and sculpt facets, bevels, and textures with the cup wheel for light-catching geometry. The turbo-row design leaves a smoother grind pattern, ready for sealing or paint. Mount panels as a modular art installation.
Terrazzo-Style Garden Pavers
Cast pavers with colored stone or glass chips, then grind the surface to reveal the inlay. Use the wheel for aggressive leveling and initial exposure; switch to finer abrasives for a satin finish. Seal for weather resistance.
Reclaimed Brick Planters
Repurpose old bricks by grinding faces flat and chamfering edges for a clean, modern look. Assemble into planters with mortar or landscape adhesive. The 5/8-11 arbor makes quick wheel swaps when moving between bricks and concrete bases.
Concrete House-Number Plaque
Cast a plaque and grind recessed numerals, borders, and textures directly into the face for a crisp relief. The diamond matrix handles precise material removal on small, detailed areas. Finish with a penetrating sealer and mount hardware.
