  Where in Seattle can I buy safe (silica-free) play sand for sandboxes?

  1 0 We just went through this same thing and found something "safe" enough to buy for our toddler. Fred Meyer (in Ballard) carries Play Sand from Mutual Materials, a local company. So we called them. They were VERY helpful and looked up the MSDS on their products. Theirs is a natural product - river bed sand. Also he said the silica of respirable size is less than .051% by weight. I forget what he said was the acceptable threshold, but this is way low for silica exposure. He also told us that if we wanted to go with a larger grain sand, since the concern is really with the dustiness of the sand, their Design Mix Paver Joining Sand is the least dusty of all their products. This is different than their paver joining sand sold at the big box stores, so you have to buy it from a Mutual Materials location - Bellevue, Redmond, Kent, Mukilteo, etc. This product is also washed, etc, so it's a fine substitute. Deciding to err on the safer side of things, we drove out to get a bag (80 lbs for around $6) of the Design Mix Paver Joining Sand. We haven't opened it up yet to see the exact size of the bits. I'm sure this sand won't adhere as well for making sand castles, etc. but I'm pretty sure my son just wants to dump it all over right now anyway, so that's not my concern. But I do feel the Mutual Materials Play Sand we saw at Fred Meyer is a fine option and if it does seem dusty at all, I read elsewhere where people suggested just keeping it a tad damp. Hope that helps! miwilyn answered in Kids Toys & Tech about 1 year ago Answer, comment & read 2 more answers »
