im about to glass my 6’7" polyurethane blank and theres extremely small specs of foam from fine sanding, how do i get this powdered foam off my board or can i just leave it on for glassing?
i have tried masking tape but that hasn’t worked very well so far.
About a year ago I helped a buddy build his shape shack. The best thing we did was put in a toe kick panel with a sliding door. This is hooked up to the dust retrieval system via a four inch hose. All the dust hits the floor and needs very little coaxing to be vacced in the grate. Makes clean up so damn easy now.
I have used an air compressor for years, the way to go. But recently I have been using one of these works pretty good! Made by Coleman for inflating LARGE matteresses. Puts out a lot of air and no hoses to deal with. Not sure how long it is going to last, Cheap to buy has one year warranty?
That above machine looks cool,
Air compressor is best, with a good water bleed valve thingy attached of course…
though, you could try a leaf blower if you had one handy, perhaps even a vacume cleaner with the brush attachment
If you didnt have a compressor handy…
(though I wonder how people use numatic tools or sprayguns/airbrush without one)
I often use a leafblower to clean the machine room,
(electric - not petrol powered)
I have found the vacuum cleaner to be much better: air compressor will blow dust all over the space you’re working in and that dust will fall back everywhere (including your blank).
Shop vac. First vaccume it, then reverse the motor and blow it off, if you can.
I have found that if you're doing dark tints, you can get a haze if you don't get the blank dust free. And you don't want that.

I would advise against using the shop vac in reverse. I messed up a board a while back doing that. When I blew with the shop vack it deposited very fine dust/dirt particles deep into the pores of the foam. It stained the blank slightly. I had done it before without problem but that time for whatever reason the vac blew dirt onto a perfect blank. I was not able to get all of the staining out and it showed in the final glass job.
