How to do when blasting the surface

Blasting is a powerful method for the concrete surface. It can be used to remove old concrete surface to lay new ones with better bonding properties, can also be used to give new textures to concrete surfaces, or to explore new materials for concrete surface aggregate, even for engraving designs Surface with template. Another reason is to remove debris from concrete surfaces, dirt and other contaminants.

Steps
1. If you do not have a blasting machine, rent a nearby hardware or home improvement store.

2. In order to prevent injury to the surrounding area covered by tarp and fixed with tape. Sandblasting abrasives can be harmful to the secondary surface, so it is well covered. Making cleaning easier for you to place a parallel to concrete behind you, tarp will catch most of the wayward abrasive.

3. Always wear protective clothing, gloves, goggles, masks before blasting work. They will protect your body from any harm.

4. Prepare the sandblasting equipment. Close all valves and take the air compressor hose. Place the funnel on the filling hole of the grinding vessel and fill it with silica sand. Reload the packing holes correctly. Put the compressed air hose. Open all the valves in the blasting nozzle and the air compressor hose. Now add air pressure to the blasting tank. Read the product manual to find the kind of need for precise pressure.

5. Let blasting hose nozzle stay away from the concrete surface within 10 inches. Now open sandblasting machine. When you start the nozzle, this valve will allow the sand to enter the air flow.

6. Use sandblaster to blast concrete. Keep the nozzle moving around when the concrete blasting. Do not put the nozzle in the same place. Keep nozzles moving from one side to another covering area to be blasting. The blasting concrete will scrap what is from concrete.

7. If you want to burst a pattern, use a template to etch the pattern on the concrete surface. Take the template and explode mode.

8. Continuous blasting the concrete surface of the cement scraped off. You will see often give the concrete to the concrete like a small stone and other sandblasting material to help you remove the cement easy to not much effort..

Precautions and Skills

- Always use protective clothing, gloves and eye safety goggles to prevent injury.

Check the sand container occasionally to avoid clumping of the abrasive. Shaking it will give you an idea how much sand left and prevent caking.

- After properly handling dust.
