Can floor leveling compounds be used over underfloor heating mats?

Yes, but the heating must not be used for 7 days after laying otherwise the heat will dry out the self leveling compound before the cement has fully hydrated which will cause cracking and possibly debonding. The use of a latex smoothing compound and flexible ceramic tile adhesive is recommended.
