For some years now it has become customary to use thermoclay blocks to build single-sheet outdoor closures, as opposed to the typical two-sheet walls.
The thermo-clay block is a clay block of lightened clay that has very good thermal and acoustic performance.
Its technical characteristics, as well as its placement system allow to reduce execution costs, to save energy and to make a more sustainable construction.
PREPARING THE SUPPORT
The substrate must be perfectly set, resistant, have made the movements of retraction, and clean of dust, paint, grease, etc.
Due to its high porosity, it is advisable to moisten it, especially in hot weather or in dry wind.
Place MALLA DE FIBRA DE VIDRIO REVAT® 110 in joints of blocks with other materials (pillars, slabs, lintels, block, etc …), covering at least 20 cm, each side of the joints. To do this, make a monolayer mortar laying on the support, about 4 to 5 mm and place the mesh on it by pressing with the trowel.
The application of the monolayer mortar on the thermo-clay block can be done manually or mechanically (projection).
It is recommended to give a first layer of 4 to 5 mm as a primer to avoid the appearance of spectra (manifestation of the thermo-clay block through the coating). Apply a second coat of approximately 1cm. above the previous one. In dry and / or hot weather, it is essential to apply this layer after 1 or 2 hours from the run of the rimera, in order to avoid a quick drying and to maintain a correct resistance.
Finally make the final finish: scraping, fratasado, projected stone …
- Do not apply with risk of rain or frost.
- Apply between + 5 ° C and + 35 ° C.
- Protect the lower parts of buildings using sockets.
