Question for GlassDave: Crushed Glass Media Blasting

IHTFP · 10-24-2009, 12:17 AM

I'm in the middle of tearing out rotten stringers inside a 22 ft boat. There is a very heavy gelcoat build up inside of the boat that I want to get off but is turning out to be difficult with my grinder. I talked to a soda blaster and he said that the soda probably would not do a good job stripping the gelcoat. He recommended crushed glass blasting. Is there any issue with this, i.e. will having crushed glass residue in the boat have a negative effect on my laminations when I build it back up?

Glass wont remove it get 24 grit grinding disc installed on 10,500 4.5 inch angle grinder , not much stopping that set up

i agree blasting wont cut it and will most likely be a pretty big mess to deal with. You need to get industrial quality grinding disks of at least 24 grit. Unfortunatly its the only way. I would use the larger disks though and a grinder in the four to six thousand rpm range.

Trust me . . . if there was an easier way . . . i'd be do'in it

Thanks, I have been using the grinder method and it definitely works it is just tough work. I thought there might be an easier way.

There is a much easier way , hire two Mexicans @ 5.00 per hour and go inside and watch Sanford & son
