SURFACE PREPARATION
Surface Preparation Overview
Two Brothers Contracting, Inc. (“TBC”) provides a wide range of surface preparation and floor covering removal services. TBC utilizes the Blastrac® line of surface preparation equipment which includes shot blasting, grinding, scarifying, scraping and milling equipment. Blastrac machines prepare concrete, steel and asphalt surfaces. Blastrac products are environmentally friendly and provide the most economic solutions to your surface preparation / floor covering removal projects. We utilize these machines with dust collecors to reduce airborne dust and particulate to provide a cleaner work environment.
Scraper Machines
We utilize ride-on scraping machines that can remove:
- Rubber and elastomeric coatings
- Carpet, ceramic tile, and VCT
- Thin-set mortar and mastics
- Epoxy, adhesives and more
- Wood
The powered scrapers are also used to remove a wide range of other materials including waterproofing membranes, roofing material, thick coatings and heavy mastics.
Scarifiers
Scarifier machines are versatile, dust-free surface preparation tools used for concrete, asphalt and even steel surfaces. Scarifiers use steel or carbide tipped cutters, in various shapes, depending on application, that are loaded on shafts placed around the perimeter of a cylindrical drum.
The Scarifiers remove oil, contaminants, traffic lines, epoxy coatings or paint. They are suitable for smoothing uneven surfaces and trip hazards, or for cutting safety grooves in ramps, walkways and loading docks.
Grinders
Diamond grinders and polishers use horizontally rotating disks to level, smooth or clean a concrete surface. Grinders or polishers coupled with the appropriate vacuum offer a virtually dust-free and comfortable work environment.
We utilize the Blastrac grinders to:
- Remove coatings or adhesive residues
- Smooth or flatten concrete slabs–including curled expansion joints
- Remove surface imperfections
- Prepare concrete for decorative uses
- Remove built-up adhesives, elastomeric coatings and waterproof membranes
Shot Blasting
Blastrac closed circuit media shot blasting machines throw a large amount of steel abrasive media by centrifugal force at the surface. After the steel abrasive hits the surface, the shot blaster recycles the media. Dust and contaminants are removed by an air wash separator and are removed to a dedicated Blastrac dust collector. This makes the process almost dust-free in operation.
Shot blasting with steel shot is the most environmentally friendly abrasive blasting method there is, because there is no use of chemical products and no waste of valuable drinking water.
We utilize our shot blasting equipment:
- To clean and prepare surfaces such as steel, concrete and asphalt.
- To remove top layers like paint and epoxy.
- To remove markings & rubber from commercial and industrial floors
- To improve skid resistance on surfaces such as sidewalks, bike paths, roads and runways.
- To generate optical and aesthetics effects on concrete surfaces
Dust Collectors
Blastrac Dust Collectors reduce airborne dust and particulate to provide a cleaner work environment, make surface preparation atmospheres more pleasant, and improve safety. A range of vacuums are available for hand tools, as well as Blastrac walk-behind and front-lead surface preparation equipment. These vacuums are system matched for best performance and increased job productivity.
