I'm re-doing a shower using an acrylic/fiberglass base. The
instructions say to put "mortar cement" under the base. Makes sense,
there were lumps of grey rock-like substance under the one I pulled
out. Problem is, I can't translate "mortar cement" into anything I
can buy at HD, etc.
My searches tell me to use the same mortar as laying bricks, or to NOT
use the same stuff, use regular concrete mix, use regular mix with
sand added, don't use regular mix as it will wreck the plastic, etc
I think I know less now than when I started.
Can somebody tell me what it should say on the bag at the building
center? Brand names are fine, if it isn't available around here at
least I can ask for equivalent product.
