Armed with Tac’s information we went to the Home depot website and looked up corner bead … Found the perfect stuff , 1.5”X 10’ long , and also looked up 3/8” stainless steel staples . The idea being we’d staple this corner bead to the floorboard (bottom ) flush with the edge , before we install it on the trailer making that job pretty easy . ( see drawing ) , then Gripper and paint over that to help lock it on , and then the canvas would go straight down the outer side and stop at the end of the beading … No way water can climb back up 1.5” to the floor … Thanks Tac !!!
I’m starting to think the best waterproofing is keeping the water AWAY from anything you want to protect .
Ants , we’ll just have to stay vigilant …
