Reabilita Cal AC Fino (Fine Finishing)

Substrate Preparation

• Substrates prepared with REABILITA CAL AC mortar, trowelled and hardened are ready to receive REABILITA CAL AC FINO. In case of direct application on another type of render, these should be regular, cohesive, clean and without any  type of material that affects the normal adhesion conditions.
• REABILITA CAL AC FINO should be applied on REABILITA CAL AC surfaces while still fresh, but sufficiently hardened to receive this kind of finish.

Mortar Preparation

• REABILITA CAL AC FINO should be mixed with the appropriate quantity of water (9,5 to 10,0 litres per 20 kg bag), in small quantities and using an electric mixer, so as to obtain a uniform and lump-free paste.

Application

• Apply REABILITA CAL AC FINO with a metal trowel so as to obtain a smooth and homogeneous film in order to fill all surface pores of the mortar already applied.
• The second layer should be applied when the first one is hardened, followed by the number of coats needed to obtain a perfectly smooth texture, never exceeding a total thickness of 1-2 mm.
• Prior to the paint application, let REABILITA CAL AC FINO dry for at least 14 days. The painting scheme to be carried out should be of silicate base or aqueous base with good water vapour permeability.

Considerations

• REABILITA CAL AC FINO should not be applied at room and substrate temperatures below 5 °C and above 30 °C. It has a curing period of 28 days.
• In h ot a nd/or dry w eather o r w hen substrates are directly exposed to sunlight, the substrate should be previously wetted and application should only be started when it is dry.
• Under these conditions daily watering of the surfaces should be carried out, for one week, so as to keep renders permanently moist.
• Application in the presence of strong winds may cause render cracking. In such case, walls should be protected so as to minimize the effects of wind action.
• The mixing water should be free of any impurities (clays, organic matter) and drinking water should be preferably used;
• No mortar that has exceeded its open time should be applied. Do not soften mortars by adding water after preparation.
• Do not add any other products to the mortar. REABILITA CAL AC FINO should be applied as it is shown in its original packaging.
