Sandblasting

Post by smccollamjr » Sat Sep 17, 2011 6:20 pm

I just borrowed a sand blaster from my neighbor but I'm not sure what kind of sand to use. I was going to use the stuff in the kids sandbox but it's too wet. I'm going to use it to strip paint and rust from a bumper. Any suggestions? I've never used a sandblaster before so any tips would be appreciated.

can't afford the gas...I've read that if you use beach sand you should wash it first because the salt in the sand could cause the metal to rust later.

I was looking into sandblasting some stuff a while back and did some research. Long story short for the cheapest stuff get the sand that goes into the sandbox. It gets more expensive from there out. I haven't heard of the salt in the sand causing it to rust, a good rinse after sandblasting and some anti-rust primer or whatever you put on it would surely negate that right?

Let me know how it goes, the rear axle I"m swapping in is in pretty good condition but the front one is uuuugly and I don't wanna grind or sandpaper the whole thing lol.

IF you have a Tractor Supply Company close to you they have some stuff that looks like black sand that works GREAT! I used it to blast the frame on my 90 F-150 and it did a really good job. I cant remember the name/brand of it though......

Dest thats pretty much just a "spot" blaster man. It would take FOREVER to do a frame or bumper with on of those. BUT for the price it could be worth a try..

use play sand from wall mart, unless your on softer metals then use the "black" looking stuff mentioned above its usually crushed wallnut shells and wont damage aluminum, brass, copper, or most hard plastics :bigthumb:

Your going to remove the paint....

Not sure what your normal procedure is for preping a surface for paint, but you should really use a solvent and clean the area being painted. If you are preping the surface correctly, how is salt in the sand going to promote rust?..... :?

that crushed glass bead stuff is pretty good too. But its a pain to clean up afterwards...plust it gets stuck in the soles of your shoes/boots. I was tracking that stuff around the house for a month after I used it. Wife was NOT happy about it either.
