Is masonry sand good for my grass?

Masonry sand can be used to level and topdress your grass or lawn.  However, Topdressing Sand is specifically designed for this purpose.  The difference is that topdressing contains more medium sized particles ideal for relieving compaction of clay soils, reducing thatch, and leveling without the sand shifting.  It is also easy to apply and to incorporate into the rootzone.  Overall, your turf will benefit more from topdressing sand than masonry sand for about the same cost.
