Compressor advice

Iv a small 25 litre compressor ( the cheap 1 from lidl ) I'm really needing to do some sandblasting with it , just rust from horseshoes , so it's not going to running at full tilt for hours and hours , will it do the job , I think the delivery rate 113 litres a minute ?..........

If you are using the small hand held blast gun that looks like a paint gun then yes in small blasts. You need in excess of 80psig and 20cfm for continuous use (For every 1Hp you get 5cfm approx.)

do not use ordinary sand i.e. builders sand as a blast media you can suffer from an illness called silicatoses same as asbestoses (lungs cant cope with the silicon in sand)
best to use something like aluminium slag, this can be purchased in 20Kg bags you may need to Google to find supplier.

Also best to use face and a breathing mask for protection

Good luck
