Abrasive Blast Cleaning of Concrete and Painted Surfaces
3.1 If blisters are exposed from inter-coat adhesion failure, blast the tops off until the same texture is produced on the underlying surface of the blisters and the top layer is adhering well. 3.2 If the coating is removed completely from the concrete, blast to clean the concrete but take care not to erode the concrete un-necessarily.

1.5 Existing concrete surfaces must be properly evaluated before the application of a coating system. It is the responsibility of the owner/specifier to assess the condi-tion of the concrete to ensure the substrate is sound and suitable for coating. 1.6 An acceptable prepared concrete surface should be free of contaminants, lai-

Sand Blasting Concrete Finish - Purpose, Process, Pros & Cons
An even more advanced technique of sand blasting is shot blasting. It is the process of resurfacing concrete finish by using metal beads (we call it shots) out of a blasting machine that removes debris and contaminants. Shotblasting offers more powerful clean because of the size and speed of metal pellets, in comparison to sand. Some useful links:

Final surface cleaning—Use abrasive blasting where possible or other mechanical means (Fig. 4) to remove residual dust, debris, fractured concrete, and other contam-inants that prevent proper bonding. If abrasive blasting is not feasible, low-pressure water cleaning using a minimum 3000 psi (20 MPa) may be acceptable depending on the bond

Sandblasting of Concrete Surfaces - Concrete Construction
The proper time to do the blasting is a question of economics. The concrete matrix will be easier to cut in the first 24 to 72 hours after casting. When blasting a surface, the operator should hold the nozzle perpendicular to the surface and about 2 feet away. The exact distance depends on the pressure being used, the hardness of the concrete ...

Concrete Surface Preparation Methods When You Can't Sandblast
This prerequisite to abrading the surface is twofold: 1) Remove the "laitance" or weak surface layer of the concrete. 2) Create an anchor profile for the coating to adhere. The requirement which most coating manufacturers use to measure the roughness of the concrete surface is the Concrete Surface Profile or "CSP".
Abrasive Blasting Methods Used for Concrete Preparation
In one option, water is added to a mixture of sand and air while in the other alternative, only water under high pressure is used for cleaning. Both wet abrasive cleaning methods include a corrosion inhibitor to minimise damage to the steel in your concrete. The surface is then rinsed and left to dry before the repair product is applied.

Gravity Feed- The only difference here is that the abrasive is located . above the nozzle. These work much better because gravity is helping to . force the abrasive down into the nozzle. With gravity feed sandblasters you are also less likely to have abrasive flow problems because the abrasive is contained better toward the point of exit.
