I am preparing to float a bathroom mudfloor which is 12′ x 9′ and I have a couple of questions. The exising sub floor is sound and pretty level.
(#1) how do I calculate the amount of sand and p. cement necessary to cover aprox. 110 sq. ft. at aprox. 3/4″-1″
(#2) what type of sand from the home centers can I use for the mix? (i.e. fine play sand, all purpose, etc.) I ask about sand from the home centers is because there is nowhere around to otherwise get sand, and home center is right next door. I was told that the play sand was acceptable, but want to get an experts opinion.
