What do you need for sandblasting?
- Sandblasting Pot
- Air Compressor
- Ceramic Nozzle
- Sandblasting Media
- Blast Hood
- Protective Gloves
Filling of sandblasting pot
Fill the pot with sandblasting media of about 150 pounds. The most common and available media is silica sand, and it costs $100 for this whole process.
There are other materials: available for filling, for instance, walnut shells, crushed glass, ceramic, and steel grids. You can choose the media according to the surface of the furniture.
The softest media is soda, and the pumice is the most abrasive used for this method.
If you are erasing the paint from plastic material, use a less abrasive material to avoid loss. Always start your first experience with low pressure and on the test surface.
Installation of the nozzle
After filling the pot with sand, close one end. The nozzle should be 10 inches above the surface of the chair.
If you are using soft media like soda, install 2/43 inches nozzle. During the utilization of abrasive material, install 1/15 inches nozzle attached to a long tube.
Use a protective kit and wear goggles
Wear gloves, full sleeves shirt, long trousers, shoes, safety goggles, and a face shield before starting the application on a wooden chair.
Cover your face with a hood: if not, the sand particles will move into the respiratory system through breathing and cause respiratory problems.
You should wear an overall while going through this to avoid dust particle penetration from the fabric. Also, sometimes it causes skin allergy and itching to those whose skin is sensitive to external particles.
Wear goggles and glasses to protect the eyes because the eyes are the most sensitive part and get injured with a small substance.
The dust particles irritate the eyes even in normal circumstances. You are using sand in high pressure and can imagine the injury from it.
Turn on its Compressor
After doing all the measures, turn on the compressor to start the procedure. Set the pressure to 60 pounds per square inch and through the sand on the surface.
Keep in mind that the opened knob of the nozzle should be against your face. Sometimes you start the compressor facing towards you, seeing how it is working.
Test sandblaster on a small area
Do not start it directly on an old wooden chair. Instead, perform a test on the small scraped area. Then, start the device by pulling the trigger and do back and forth movement.
This process involves overlapping but does not overlap pass by any more than 4/6 inches.
Turn off the compressor and see the results. If there is an uneven surface, bits, and chunks, start the compressor and move it more rapidly than before.
Repeat this procedure, and then start using them on a small surface because the results are positive for small test surfaces.
Sandblast the wooden chair surface
As you have tested the sandblaster, start it on the wooden chair. Then, move your device horizontally in a back-and-forth motion.
Keep the distance of about 10 inches from the surface to avoid unnecessary damage.
Set the pressure of 60 pounds per square inch at the start and increase it to 120 pounds per square inch.
Throw its material on a whole surface with the same pressure. See the results when you have done it a single time.
Repeat this procedure if there remain any patches and uneven surfaces. If still there are no desired results, repeat this procedure with an increment of 10 pounds per square inch pressure.
Fill the pot with other abrasive ingredients such as crushed glass and steel grid if sand is not working well.
Check the results after 5 seconds of the whole process. Move it rapidly if too much material has vanished.
Where should I sandblast my wooden chairs?
