Topic tags/keywords: wood sandblast sodablast

I witnessed a demonstration at dawson mcdonald i brought my own heavily painted and shellaced and varnished wood. The results were driftwood at any pressure level. I owned a furniture stripping shop in maine with methelyne chloride dip and flow over tanks.we pressure washed the furniture 500psi after stripping.came out super clean even on veneers.i even had a special machine to purify the stripper laden rinse water for reuse (required a special liscence from state of maine). After being tested and fined 6000 dollars by osha for meth.chloride exposure levels i decided to look into wet soda blasting on wood. It does not produce a satisfactory result on any wood or finish type. So take it from someone who has put many hours of research into it. Theres no substitute for chemical strippers. The only osha loophole is if you are sole proprieter with no employees then and only then you are not subject to their regulations. Family members can work for you also and be exempt. Mike tibb

Have you ever looked at dry ice blasting? Since the blast media sublimes you are only left with what you knock off the wood.

It seems like a neat technology for cleaning wood (not paint stripping) so I would like to hear your opinion.

On the OSHA thing, there is a difference between state and federal authority. I’ve ran fed OSHA agents off mill property before.

That aside, what are you trying to do? If you want to sandblast for a sign, most use 3-M or equivalent resistance material, cut out what they want removed, then hit the wood with a high pressure blaster.

If you just want clean, stripped wood, Mitchy’s approach would be best. If that isn’t available or an option, still look at chemicals (with masks, etc.). You could use heat, but, again, wear protection against vapors (including lead paint, if applicable). Otherwise, invest in a hundred dollars or more in sand belts and paper.

Howdy guys to reply to dry ice.
Yes they did mention dry ice blasting at dawson mcdonald. They didnt have any on hand to demo with but he said it is a little finicky to work with because if you order or buy too much it melts and you have to order or buy the exact amount you intend to use within 48 hours in summer. .
On a different note i saw an ad today for graco vaporblast system called ecoquip 3. That system is awesome you can blast paint off a lightbulb it showed in video. People are using it for mold remed. On spruce .pine.cedar. very little damage no dust 20 times faster than media blasting. You should look it up. Its state of the science stuff .looks expensive though and requires 100cfm at 90psi they might make a smaller model im going to keep looking into it it has huge money making potential for wood blasting of all types. As far as osha i ended up working with safety works from maine .gov and they took 3000 off my fine and i paid 100 a month till it was paid but i didnt want to be sole proprieter again to exploit the loophole.i enjoy being incorporated . Thanks for responding. Mike tibbetts. Gray maine
