Fourth precaution is to ensure no adhesive material goes into these gaps between the boards.

    13.  What should I fill in the joints after installing tiles / stones on Plywood boards?

    You can fill epoxy grout like LATAPOXY® SP-100 stain proof epoxy grout or SpectraLOCK Pro premium grout in the joints within the periphery of each board. On the peripheral joints of the boards, one needs to fill silicone sealant or cement based grout mixed with LATICRETE® 1776 Latex admix.
