Lebro Posted June 1, 2019 Report Share Posted June 1, 2019 A neat trick I have discovered. Why buy "Sand / Grit blast media" Cheapest on ebay (inc postage) £16 per 25Kg when you can buy "Kiln dried sand" £4.50 per 25 Kg from local builders merchants. It works very well in both my dry air sand blast cabinet, & with my wet pressure washer attachment. Bob. Quote Link to post Share on other sites
ed_h Posted June 1, 2019 Report Share Posted June 1, 2019 Agree. That's about all I use these days. I have to screen it, though, when I first fill the tank, else the occasional large pebbles will clog the nozzle. I usually blast on a large tarp and recycle the sand. This brings the cost of the media to almost zero. Ed Quote Link to post Share on other sites

Hi Bob and Ed, blasting with sand is not recommended because it can cause serious harm to the lungs, but I guess you are aware of this. The fine quartz dust can result in Silicosis. In the Netherlands it is forbidden for this reason. Regards, Waldi Quote Link to post Share on other sites
Lebro Posted June 1, 2019 Author Report Share Posted June 1, 2019 (edited) Waldi. For dry blasting I do it in a sealed cabinet, & the "media" gets re-cycled. A vacuum cleaner is attached to the vent port to suck (& filter) the fine dust created. When wet blasting using a pressure hose the media is lost (I usually do it on my lawn where it disapears into the soil), & being wet there is no dust. Ed. No lumps in the stuff I get it is extremly fine sand intended for brushing inbetween paving slabs, etc. Bob. Edited June 1, 2019 by Lebro Quote Link to post Share on other sites
ed_h Posted June 1, 2019 Report Share Posted June 1, 2019 Yes, for silica based sand, respirator is a must. Bob--OK, that fine, very uniform stuff for filling in paving here is called silica sand. It works great for blasting. The stuff I have to screen is cheaper, around $3 for a 60 lb bag, I think. In bulk, I think it's less than $20 a ton. Ed Quote Link to post Share on other sites
