The shot blasting process is a dust free process. By removing the top layer of covering and concrete the pores of the concrete are exposed. The new coatings can then work themselves into the pores of the concrete and bond with the concrete through chemical reactions. This is vital for creating a strong bond for the new surface coating provided by the Libra Envelope floor system.
The fact that it does not use chemicals there are no chemical residues so the process is very environmentally friendly. It can be used in areas where dust or chemical wastes are prohibited.
In this photo, you can see how effective shot blasting is. You can see on the right side of the image, the floor scratched, mucky and with many stains although it has been pressure washed.
On the left side of the floor, it is almost as if it is a brand new floor. In this case, a shot blaster for concrete is used to actually prepare the surface for traffic coating application in the underground parking.
Many times people will need to prepare a floor to paint it or apply some other coating or texture to the floor. It is quite difficult to apply paint to a floor when it has gunk all over it, which is why shot blasting equipment can help to make the process run much smoother.
