Wet blasting a shed

I was asked to paint my shed by anon who I live with ( no names to protect the guilty ), now the blue yes blue paint was sprayed on as it’s a big shed, has started to peel and fray as it’s a bit old but sturdy. So I thought how to take the retched stuff off without danger to me, I have a sand blaster kit I have used years ago with some shot left, but didn’t want dust everywhere and especially in my lungs.
So I saw marcher do a wet sand blaster lance, now being a careful soul it was a few pennies so I looked around and turned to flea bay and chose what I thought would be a fine choice.
I have a Karcher a K4 stated to run at 130 bar so should be up to it, so using the shot I had, I tried it on a section of my shed. I was quite surprised to see how easily the paint came off, in fact it was back to bare wood and ready for a proper shed coating
The facts are it works best done on a hot day because with water you will get a bit wet also use goggles to keep shot out of eyes as it bounces a lot.
The cost adapter for using is about £20, I am using now fine Glass beads to see if it’s any better and 25 kg is £17.
I let the shot on the floor dry out and will sieve it and use again, not sure If I can do it with the glass beads but will see.
The patch I have done took 15 minutes as I had to keep wiggling the bit in the shot as it was running dry every so often due to not having enough.


has anyone else tried this method and did you do anything different, would like to hear tips as well.
