Hoping for some advice on the underfloor heating project I was doing. Basically when covering the heating mat in a levelling compound, I completely underestimated the amount of compound needed, and only managed to cover about 80-90%% of the floor. To make things worse I poured from the middle out, which has caused the edges to have either no or very little compound. The bulk of the mat is covered and fixed in place by compound, however I'm worried about the edges, and exposed heater elements.
I guess at this stage I'm wondering what my options are, and any advice would be greatly appreciated. I'm guessing they're somewhere in the region of:
- Fill the spaces with an extra levelling compound
- Tile as normal but using more tile adhesive over exposed area's
- Start a new
