i'm embarking on a new project for me.. pool coping using Oak concrete pavers. they are 8" wide by 12" long and 2 3/8" thick. they are being installed on a steel wall inground pool where the steel bond area is 5.5" wide.
coping sits on top of steel wall and overhangs 1". the other 6.5 " of block rests in a bed of mortar.
installation is for northern climate.
first few blocks went down but i can see my mortar is like 3" thick .. i need more gravel so my mortar is thinner. also i forgot to brush on bond agent to underside of paver that is in contact with mortar for these first 9 blocks.. hope they hold.
bond between paver and 5.5" wide steel pool bond beam is made with PL 9000 (because this is the only product i could find that said it is for outdoor use for bonding between concrete & steel, and between concrete and plastic which is the stairs). this glue goes down in two beads, 3/8" thick.
after coping is set up and leveled, i put a monster block on top to weigh it down so glue doesn't move paver during cure process.
i'm leaving 3/8 to 1/2" gap for grouting. but i 'm not sure what product to use for grouting? i was thinking mortar + bonding agent in icing cake bag.. not sure if this will work for the couple of caps that are very small around 1/8".
