Covering Radiant heating with self leveling conc
Why do you think the SLC needs to be 1/2" thick? Also remember it is self-leveling, so to get half inch here, it may be 3/4" over there. See what I mean?
Also remember that it does not really level its self, it needs a little help. A small plastic rake might be useful.
You need to mix one bag after another quickly. You need help. Plenty of buckets, water pre measured and someone mixing while another pours. If you're not careful you'll create bumps instead of eliminating them.
A #50 bag does about 50 sq. ft. @1/8" thick. So mathematically you need 16 bags, OUCH $$$. But if you have to go about 1/2" it's likely to take more depending of how level the floor is. I'd buy 20 if it were me.
You know the heat is gonna warm the floor not heat the room right?
