Due to failed water filtration in condo above, my kids condo at school was stripped to the studs- including shower pan. As it was an odd size, I could not find a pre-made pan. So I made a custom one. 1 1/2 inch dry packed sand mix sloped to drain, 40 mil PVC liner with corner folded into notches cut out in the studs and edges stapled 7 inches above pre-slope and over shower curb, and then another 1 1/4 inch sloped dry pack sand mix and mortar poured into form made for curb. Turned out really good. I talked to the sheetrock contractor and physically showed him the blue painter's tape I ran around the top of the 40 mil PVC liner and instructed him NOT to place screws to hold the hardboard below the tape as to avoid penetrating the liner. Result-6 screws about an inch from bottom of the hardboard. Before informing me, he removed the screws, squirted in Gorilla glue and replaced the screws. Does Gorilla glue even stick to pvc liner? It would be extremely difficult to start over as I had to cut the 2 inch pvc pipe below grade and its thru a concrete subfloor. Suggestions? I had planed Red guard the walls, but now it may need Kerdi liner extending well onto the floor. Would this work, and if so, how close to the drain should I get as I have read to avoid getting moisture sandwiched between two liners. Also, Red Guard- thumbs up or thumbs down? Other solutions?
Thanks
