    Gypcrete Pours

    It's a kind thought toward the rockers, but the gypcrete has to sit at least a week to cure, unlike concrete that needs a month. Pouring gypcrete should come after the rockers, to properly fill to the edges, and more importantly to eliminate chipping the gypcrete. It is very soft and can be scratched or chipped within its curing time quite easily, and even if you love rockers, you know they don't care about dropping tools on the floor. If you want temp heat, try hooking up a temporary unit heater off a zone of your boiler. For the tubing, you can just use heater hose, and they can control the temp. There is also a nice 120 volt t-stat that will moderate the fan on the unit heater for you to keep the room from roasting. Leave the zone circulating the entire time though.

    By light weight do you

    mean gypcrete type mixes? I prefer to install after rock, also. As long as the installers are neat and take care not to splash and damage the walls.

    Keep in mind gyp pours contain massive amounts of water. You need some heat AND ventilation to cure the pour. if not you will have a tropical rainforest and a soggy mess!

    I mistakenly went with the GC's wish on a gyp pour last year and poured before the sheetrock. It took almost a month, and lots of fans to dry out the blown in cellouse insulation that soaked the moisture like a sponge.

    Painfull lesson :)
