To increase the size, you’d have to build the new mould around the existing and pour new concrete around it, using either the craft mix or worktop premix.

When going over underfloor heating, the substrate onto which the microcement is laid needs to be dry. The moisture content in the floor should be no more than 4-5%. Ideally, the underfloor heating should have been operational for at least 2 weeks AFTER the full cure of the substrate below. The underfloor heating should be … Continue reading Can I use Microcement Over an Electric Underfloor Heating System?
