What type of jointing sand should I use to stabilize a joint with SB-1300 Joint Stabilizing Sealer?
It is best to ask for a recommendation from your local paver manufacturer — joint sand can be very regional. The sand should be dry and bagged and should conform to ASTM International Technical Standard C-144. The sand does NOT need to be polymeric sand but should be clean and dry. Old, dirty and uneven sand can impact the ability of the sealer to bond.
