Concrete Preparation

Shot blasting

The shot blasting system incorporates the high performance airless centrifugal wheel for propelling blast media in a controlled pattern and direction. Metal abrasive thrown by the rapidly rotating blast wheel scours the concrete surface and rebounds along with removed contaminants into a recovery chamber. Pulverized abrasive, dust and contaminants are removed by a separate dust collector. Very little abrasive is lost and the usable media is returned to the storage hopper for re-circulation by the blast wheel.

                Shotblast Southwest Inc. will use a fine or coarse shot to produce the correct profile for your final resinous concrete floor covering. A finer shot would be used to produce a finer profile for applications like epoxy concrete flooring and urethane film. A coarse steel shot would be used to produce a deeper profile for use with topping and overlayment concrete floor coverings

 

Features and Benefits:

  • A dry process permitting immediate installation of coatings with no moisture to affect coating adhesion.
  • No fumes.
  • No pollution or dust
  • Little or no interference to your operation
  • Ideal surface texture for mechanical bonding of coatings
  • Etching of slippery surface where coatings are not specified.
  • This system will remove most coatings including elastomeric urethane.

Applications:

  • Airplane Hangars
  • Brick and Tile Floors
  • Convention Centers
  • Factory Floors
  • Food Processing  Plants
  • High Rise Buildings
  • Offshore Drilling Rigs
  • Parking Garages
  • Ship Decks
  • Shopping Malls
  • Storage Tanks
  • Tennis Courts
  • Terrazzo Floors
  • Vinyl Mastic Removal
  • Warehouses

 

Soda blasting

Is a paint stripping technology that propels a bicarbonate-of-soda media, via compressed air,  onto the area to be cleaned. This process removes paint and contaminants without harming the the substrate surface.

The blast material is a specially formulated sodium bicarbonate:

  • Non-toxic
  • Non-hazardous
  • Food grade
  • 100% water soluble
  • Completely environmentally safe (baking soda)

Soda blast particles remove surface contaminant by the energy released as the particles explode when pressure-driven into contact with the contaminant surface. The resulting release of energy disrupts the contaminate surface and blows it away-thus leaving the substrate completely unaffected.

Sand blasting is very damaging to the substrate because it will stress relieve the metal surface, causing it to bend or warp. This is known as oil-canning.
