DIY Sandblasting

Tuesday, January 26th, 2010

Many of my readers ask me about sandblasting, but one of the main questions is:

Can I Do Sandblasting Myself?

The easy answer here is no. Of course, with the proper training and experience anyone can master the skill of sand blasting, but for your average homeowner, this is a task best left to the professional.

The process comes with its share of potential hazards. Besides the danger inherent in grits of sand being shot out of a gun at high pressure, this cleaning method can also cause respiratory problems if the practitioner doesn’t take the proper precautions.

The fine silica dust that is a consequence of propelling sand and other materials against rough surfaces at high velocities can accumulate in the lungs over time and cause silicosis. That being the case, only perform sandblasting tasks in a ventilated area while wearing protective suits and the proper respiratory equipment.

Well, folks this is a rational response but my friend Eric is working in a sandblasting information product. This product will be available very soon. And it will allow anyone to properly sandblast your projects without potential hazards and doing a professional work.

I’ll keep you informed.

What Is Wet Sandblasting?

You can think that sandblasting is always dry. The slightest amount of moisture will plug up a blaster. You ever go to the beach and pick up wet sand with your hand?, theres no way that will ever go though a nozzle.

But, in fact, there is a wet sandblasting type. Wet sandblasting is more like powerwashing,where sand is mixed in with the water for abrasive purposes.I’ve seen it used in industrial applications like bridges or on sidewalks.

Wet Sandblasting is a common procedure for removing paint and rust from steel or other metal surfaces. With this procedure we use an abrasive material mixed with the waterjet to create an abrasive spray to create the desired white metal finish, perfect for recoating.

A recent development along the lines of abrasive cleaning is “Water Soluble Media” (baking soda) which offers distinct advantages over wet sand blasting.

For most cleaning and depainting jobs, the new portable soluble media blasting media is largely desirable as disposal costs are usually greatly reduced. Because of the extreme abrasive qualities of different sand and garnet, baking soda based media is often preferred in certain applications such as glass, soft metals, brick and ceramic.
