Loose Laid 5 x 5 meter 20 sq meters , Garden gym room last year with JHS 5 mm supa lock tiles. Been back once already to trim back perimeter, to make expansion gap. South facing glass on one wall line grown again in recent hot weather, so going back again to stick. Cant use 2 pack due to open time too short, cant clear the room , have to do by sections. What's better... F73plus or F48 Plus ?? Or any advise apricated Thanks Steve
