Sandblasting At Home Dirty Tricks

Sandblasting Expert — Thu, 08 Jul 2010 07:57:26 +0000

Sandblasting is an industrial technique that propells very fine bits of material at high-velocity to clean or etch a wide range of surfaces. Although is extensively used in industrial areas you can also use sandblasting at home.

Here are my dirty tricks to use sandblasting at home without problems:

1.- First, you must prepare the zone in which you will make the work. If you don’t have a sandblasting cabinet you can easily build a homemade sandblast booth. If you want to make the sandblasting work outdoor first you must consider that the area can not be affected by the wind.

2.- Which sandblasting equipment is more appropiate to sandblast at home?

You can use sandblasting kits that will remove unwanted rust, paint and scale in no time. My main recommendation is that you don’t have bother with the small feed sandblasters like siphon blasters. I have one and it goes for about 10 seconds between fills. If you’re serious about doing big areas, you might consider one of the inexpensive 40lb blasters .

The siphon feed design sprays most abrasives including glass beads, aluminum oxide, steel grit, silicon carbide, walnut shells and more. easily removes rust, scale, and paint from parts and small equipment leaving a satin finish that will allow for further painting preparations or applying the final coat.

On the other hand, 40 Lb. pressurized abrasive blasters are better tools for sandblasting at home purposes. Pressurized design gives 30% more blasting power than siphon blasters.

3.- Always use protective accessories like sandblaster gloves and protective glasses.

Be creative and etch designs or lettering on any number of surfaces including glass tile, wood working and furniture.

Sandblasting Vs Soda Blasting in Yachting

Can I use sandblasting technique to remove the old paint from my boat?

Recently I stumbled upon a forum post in a sailing website. One forum member of this website was worried about which specific technique is more appropriate to get a perfect surface finish in yachts.

According to sailing experts soda blasting is perfect for fiber glass boats but it gets poor results in steel frame yachts. One user even claimed that soda blasting left a pitted surface but did not remove all the loose paint . He had to come back and re-do it. On the other hand, sandblasting technique with “000″ grit sand gave the best result back to steel surfaces in boats.

In yachting both techniques, sandblasting and soda blasting, are mainly used to get rid of old paint.

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.

Sandblasting Custom Wood Signs

Hi.

I want to start making some custom wood signs using sandblasting. I’ve seen lots of different sandblasting kits and hoppers, and I’ve not found anywhere what is used for the masking.

Can you help with this?

Thanks!

“Resist” is the mask used to keep the abrasive off the areas you don’t want blasted. Hand cut masks are made by literally cutting the design out of a piece of material that will resist the abrasive long enough to get the effect you want on the wood.

You can draw on the resist or transfer the design with carbon paper.A good way is to print the design life size – Then use Spray Mount glue on the back side of the paper, stick it directly on the resist and cut through both to create the mask.Make sure to keep your knives sharp at all times or the mask will stretch as you cut it.Some start out using Contac brand paper for their first hand cut masks. It’s cheap, but it has its problems. The glue may not remove easily and it often takes several layers if you are using an aggressive material such as iron bits.

Layering makes it not so cheap but it is easily available. Use the
foam cushioned type for deeper cuts. It lasts a little longer and costs about the same. Several companies make vinyl and rubber resists intended for sandblasting. you get a better product for your money. They vary in thickness, The 8 to 25 mil varieties from 3M, Anchor
Continental and others cut easily and work well. To find sandblasting
resists, check in stained glass magazines for ads, ask at a local stained glass shop or do an Internet search. Another possible source is a commercial shop that advertises sandblasting work.

Thanks for this interesting question.
