MORTAR MAINTENANCE
To ensure the good absorbent resistance, thickness () of the coating mortar layer requiring as follows:
       With flat roof, WC, etc... = 30 - 40 mm
After coating completely, should pave with Chinese, Ceramic or Mosaik brick in order to increase heat durable intensity of the absorbent resistant mortar layer. With terrace without paving brick. After mortaring that it is still wet, using small stone to spread all over from 5 to 10 mm then ramming regularly.
        With covering wall: = 15 - 20 mm

CONCRETE MAINTENANCE
By slight and sufficient water spraying immediately after the fixative absorbent resistant concrete layer, avoid to wreck the concrete surface and spray water within three days, each day of two times.

Comparing with the normal concrete, the Hysuca additive concrete develops the higher and earlier intensity, its solid fixation time is faster and earlier casing unbinding (after ten days), the composition is used earlier, the good absorbent resistance and period saving, increase force-resistance intensity for the concrete, the better concrete surface after finishing.

HOW TO PROCESS LEAKY RESISTANCE OR JUNCTION ATTACHING
Healing leaky chapped traces: First of all, must carve and widen the chaps turning into shape V and from 20 to 30 mm in width for the mortar may be able to attach together completely and unite well, make the rough surface, clean up debris, mixtures before mortaring, must spray wet water in the surface, clean stagnant water, after it is dry, coating/painting an oil mortar (the diluted cement with the Hysuca additive), after coating the absorbent resistant mortal on requirement.

Mortaring the old works: Must make the rough surface (outside), clean up debris, mixtures before mortaring, must spray wet water in the surface, clean stagnant water, after it is dry, coating/painting an oil mortar (the diluted cement with the Hysuca additive), after coating the absorbent resistant mortal on requirement.

Attaching the junctions: Before processing, must locate by fixed mechanics force, after carrying out to make rough, clean and the following steps as mortaring the old works.
