Never sandblasted before
on May 12, 2011
KEY THINGS TO KNOW - details below
Amount of pressure needed or size of compressor
Regular flow of sand
Angle you are pointing the gun
grade of sand
I never sandblasted before. I had a project that I thought was small and the reviews looked good on this gun, so I got it. I have given it 5 stars because it did what it said. I've written this review to help other novices as they consider getting a gun.
First, to help you understand my review, I'll give you the context. I wanted to sandblast my rusty, old boat trailer. I figured it was a small job since it is not something body mechanics are interested in doing. However, I learned that it was not a small job. It took me hours to do and hundreds of pounds of sand. I'm glad I did it. I now can do other projects and know what I'm getting into.
It took me sometime to get the flow of sand to the point that it took the rust and paint off at a reasonable speed. (To me a reasonable speed is about 1 square inch per 5 seconds. Not like at an auto shop, but good enough for my project.) My compressor is able to do 135 psi, but not continuously. I found at 120 psi I was able to get good results. However, because I was doing a trailer which required me to have the gun at different angles, the canister did not work well. I kept losing contact with the sand. I got a 2' hose (I think 3' would work too) and attached it to the end of the gun. I put the other end of the hose in a bucket of sand and was able to move the gun around to get the angles I needed and also have a nice flow of sand.
SAND - RECYCLE
Someone said 5 pounds of sand goes a long way. I guess that is true on a small project, but not for a trailer. First I got fine sand, but that didn't work well. I picked up medium grade and that was much better. If I could have gotten even coarser I would have. The gun doesn't have a problem moving dry sand. After 70 pounds and only getting 1/8 the way done, I decided I would recycle the sand. I put a tarp down to catch the sand. I used an old window screen to clean it. It worked great and I didn't have to drive 50 miles to get more sand. I recycled it many times and it was still so clean I kept it for another job. I put it in a plastic bag in hopes to keep moisture out.
I'm back on Amazon to get a sandblaster hood. I should have spent the $20 for the first project like someone suggested. I had tight goggles, a mask quality mask for breathing and ear plugs and still the sand got everywhere.
Well, I hope that helps. Enjoy yourself, it is a blast :-)
