Play Sand

Washed and screened play sand starts as raw sand that gets rinsed to remove clay, silt, and organic debris, then passed through screens to sort particles into a narrow, fine size range, roughly 0.1 to 2 mm. Washing is what keeps the fine dust content down and gives the sand its light, consistent color instead of the muddy tint of unscreened sand. Screening is what makes it feel soft underfoot rather than gritty, since it removes the coarser, sharper particles found in mason or concrete sand. Not every product labeled play sand goes through the same rigor of washing and screening, and specifications vary by supplier and by region, so it is worth asking your local yard exactly how their play sand is processed and whether it has been tested for dust content, rather than assuming a name on a label guarantees a specific standard.

Start by measuring the footprint and deciding on target depth before ordering, since play sand's job is cushioning and texture, not structural support. For a sandbox, dig out a shallow bed, add a gravel layer if drainage is poor, then fill with sand and rake it level. For a fall zone under equipment, clear grass and debris, install a border to keep sand contained, and fill to the depth called for by the equipment's fall height rather than guessing. Do not compact play sand the way you would a paver base, it is not designed to lock together under pressure. Plan to top off depth every season or two as sand compacts, migrates, or gets tracked out, and rake it periodically to keep it loose and evenly distributed rather than packed hard in high traffic spots.

Compared with mason sand. Mason sand has fine but slightly angular grains meant to bind mortar and grout joints. Play sand is ultra fine and rounded for softness underfoot, and it does not conform to mason sand specifications like ASTM C144, so it should never substitute for mason sand in masonry work.

Compared with concrete sand and fill sand. Concrete sand is coarse and angular, built to drain and compact under pavers and slabs. Fill sand is coarser still and drains well but won't compact tightly either. Play sand trades both of those properties for a soft, fine texture, so it is the wrong choice for any structural base.

How much do I need. Estimate coverage as square footage times depth in inches divided by 324 to get cubic yards, or use the depth chart above directly, roughly 162 sq ft per yard at 2 inches and 108 sq ft per yard at 3 inches. Measure length and width, decide your target depth from the specs above, and round up slightly to cover uneven ground. For anything approaching a full cubic yard, bulk delivery is almost always more practical and cheaper per pound than buying dozens of 40 or 50 lb bags.

How it is sold and delivered. Play sand is sold in bulk by the cubic yard and delivered loose, either dumped in a driveway or placed with a machine depending on access. Bagged sand makes sense for small top offs or tight access sites where a truck can't reach, but once a project needs half a yard or more, bulk delivery cuts down on both cost and the labor of hauling and opening dozens of bags.
