Prep Methods Used Before New Polymer / Epoxy / Urethane Flooring is Applied
SHOTBLAST SERVICES uses state of the art machinery and equipment to remove old flooring in preparation for epoxy or urethane flooring systems.
Steel Shot Blasting Method for Typical Applications
Steel "shot blasting" (aka "bead blasting") is typically the recommended method of mechanical abrasive surface prep by most coating Manufacturers. Shotblasting, also known as shotblast, shot blast, and bead blasting, is recommended for many reasons. Shotblasting offers high production rates, blast pattern accuracy, and wide abrasive selections make steel shot blasting an attractive choice for a variety of resulting surface profiles.
It eliminates the use of harsh non-eco friendly chemicals and leaves the concrete floor with the desired profile ready for coating. Applications such as mastic and glue removal, surface cleaning and texturing, concrete etching and profiling, and epoxy and sealer removal makes shotblasting an attractive alternative in various circumstances. SHOTBLAST SERVICES can deliver any surface profile from CSP1 to CSP9 per ICR1 standards. (See www.icri.org)

Industry guidelines for creating surface profiles
The International Concrete Repair Institute (ICRI) has created a technical guideline #03732, "Selecting and specifying concrete surface preparation for sealers, coatings, and polymer overlays." This guideline provides concrete surface profiles of CSP 3 to 9 which are used under the following conditions.
- For coating applications from 4-5 mils in thickness, the surface profile shall be a CSP 3. This is known as a light shotblast.
- For coating applications from 15-50 mils in thickness, the surface profile shall be a CSP 4 or 5. This is known as a medium shotblast.
- For coating applications from 40 mils to 1/8" in thickness, the surface profile shall be a CSP 5 or 6. This is known as a medium-heavy shotblast.
- For topping applications from 1/4" to 1/2", the surface profile shall be a CSP 6 or 7. This is known as a heavy shotblast.
- For concrete overlays greater than 1/2", the surface profile shall be a CSP 8 or 9. This is known as an extreme shotblast.

Scarification for Heavy Duty Applications
During scarification, SHOTBLAST SERVICES uses steel and Tungsten carbide cutters to break or chip away a variety of coating materials. Scarification procedures used on horizontal surfaces can be a highly efficient method of removing urethanes, epoxies, polyurea, thermoplastic, etc. SHOTBLAST SERVICES provides surface preparation of existing and new concrete floors through a mechanical dust-contained scarification system.
Using hardened tungsten carbide cutters, the scarifying process removes the toughest finishes including layers of concrete impregnated with contaminates, epoxy overlays, curing compounds, sealers, laitance, coatings, elastomeric membranes, traffic markings, and other surface coatings. The result is a prepared high profile surface.
