Coating over thermo-clay

Thermo-clay blocks are characterized by their high porosity and low density, and allow installation without vertical joints and are excellent thermal insulators.

Preliminary analysis

This type of partition wall has intrinsic characteristics that differentiates it from other substrates, as they are excellent thermal insulators due to their low density and high-water absorption, due to which they require treatment prior to the application of mortars.

In addition, due to their peculiar installation method, without vertical joints, the way the jambs are filled, framework pass-throughs, pillars, etc., certain precautions must be taken before cladding partition walls.

Technical considerations

The blocks must be previously moistened, due to their high degree of porosity. This ensure good adherence and, subsequently, the correct hardening of the coating mortars.

Next, the window and door lintels are filled to avoid an excessively thick finish coat.

Previous sealing with the mortar is advisable to avoid marking the substrate joints.

After 24 hours have elapsed, check that it is sufficiently solid to receive the final mortar coat.

If not, soak with water and wait an additional 24 hours.
