benny Posted March 25, 2013 Posted March 25, 2013 Hi Guys, Me and my brother have been looking into some blasting options. Upon research we found out about "wet" sand blasting, results seem to be good by just using an attachment on a karcher see link- http://www.justtools.com.au/prod4035.htm Anyone have any experience using these, also most likely means there is no need for any heavy duty respirator as the silica particles wont travel due to being wet?

lightmaster240z Posted March 25, 2013 Posted March 25, 2013 My father in law uses this all the time on his Hudson Chaises.It's very effective in removing the build up of stuff from the rail but won't recommend on thin metal as rips in to it. Bruce Quote
lampy Posted March 25, 2013 Posted March 25, 2013 I have one of those attachments. They work well but you do need a fairly high pressure unit. around 3000 psi I just use ordinary builders sand that i sieve with a wooden frame with a piece of flywire attached. You need to make sure the sand is fully dry or it can clog the nozzle Quote

luvemfast Posted March 25, 2013 Posted March 25, 2013 Using wet sand, ie. WATER to blast rust off a Z Great idea Benny Think that might be your best idea EVER! Quote
benny Posted March 25, 2013 Author Posted March 25, 2013 I thought so to... This is the process... blast with either wet or dry... then sand the panel)raw) then lock it in with choice of primer/epoxy. I dont see a problem with it... seems to be much gentler on panels too seeing you dont have the heat. We do have the option of buying a 20Gallon pressured dry blaster aswell just looking at all options Quote
Ledge Posted March 25, 2013 Posted March 25, 2013 Lurchie's got old faithful out again , ha ha Water and bare steel are not each others friend. even if you "lock" it in straight away. Tears will be falling Quote

luvemfast Posted March 25, 2013 Posted March 25, 2013 even when sanding afterwards preparing the surface? You have the response of a toolmaker, boilermaker and coach builder. What would they know about steel? Quote
Ledge Posted March 25, 2013 Posted March 25, 2013 Benny at the end of the day its your car You may get the paint off however you like. Will whoever told you that this is a good way To blast warranty your paint work? I could bet my left nut it WILL rust. Mate i don't even like wiping down a steel panel With a damp cloth after de oxidine. But if you dont It will be worse. I personally would not blast wet. Cheers Paul Quote
AK Posted July 24, 2015 Posted July 24, 2015 Hi Benny Hope all is going well. I was thinking of trying this as well - it been a while since you posted - did you ever try this? How did go ? Was there any rust problems that eventuated or any special treatment of after west blasting. Thanks for any advice. Cheers AK Hi Guys, Me and my brother have been looking into some blasting options.

gilltech Posted July 24, 2015 Posted July 24, 2015 What do you think is going to happen at all the seams, panel overlaps, crevices, pockets, inside rails & folded areas you can't access, when spraying wet sand around? Also, high pressure will warp panels & take the tension out of the metal. Don't use sand, wet or dry, period. Quote
Administrators gav240z Posted July 25, 2015 Administrators Posted July 25, 2015 After the advice in this thread, I'd be surprised if anyone still wants to to this. Quote
zzzzed Posted July 25, 2015 Posted July 25, 2015 If it was me I would blast with water and rock salt Quote
chris240 Posted July 25, 2015 Posted July 25, 2015 Sorry mick, have to disagree, swap the water for extra virgin olive oil, then rock salt, then oregano... Quote
