REABILITA CAL AC PURE is a dry mortar, exclusively formulated from Natural Hydraulic Lime, intended for the execution of finishes with excellent permeability to vapour ideal for renovation and rehabilitation solutions of old coatings. This finish mortar, based on lime, has got photo-catalytic properties enabling, in the presence of sunlight, dissociation of dirt, fungi and other organic and inorganic compounds present in the atmosphere, keeping surfaces clean and contributing to the reduction of atmospheric pollution. In addition to these properties, the use of lime in its production makes it possible to associate traditional lime characteristics, such as, high compatibility with old substrates and excellent durability, being ideal for rehabilitation, especially in areas whose effects of deposition of dust and pollution are more notorious, such as urban environments. These self-cleaning and decontamination features allow to reduce the need for maintenance.

3. 3 TECHNICAL DATA SHEET REABILITA CAL AC PURE NHL BREATHABLE FINISH WITH PHOTO - CATALY TIC PROPERTIES REABILITA CAL AC PURE final surface should be trowelled and f inished as a polished - type o r sanded finish . To obtain the sanded finish, apply the "sponge" technique to the surface . To obt ain the polished fin ish , smooth the surface by using a metal t rowel . In this application process the necessary care should be taken, using the appropriate techniques to ensure a uniform and continuous appearance, eliminating creases or other imperfections . In render repa ir o r in reh abilita tion schemes that require the execu tion of large thicknesses in the re nder s, the incorporation of ISOVIT REDE 160 glass fibre mesh with anti - alkali treatment should be provided for over the first layer while still fres h of REABILITA C AL AC PURE . With REABILITA CAL AC PURE painting is not needed and its expos ure to the sun is essen t ial for the development of its decontaminating and self - cleaning characteristics . d) Restri ctions REABILITA CAL AC PURE 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 hot and/or dry weather or when substrate s are directly exposed to sunlight , the substrate should be previously wetted and application should only be started when it is dry . Unde r 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 minimi ze the effects of wind action . e) Complementary Advices 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 morta rs by adding water after preparation . Do not add any other products to the mortar . REABILITA CAL AC PURE should be applied as it is shown in its original packaging . 5. PACKAGING AND VALIDITY Packaging 25 kg paper bags in plasticized pallets of 48 bags . V alid ity 6 months provided the conditions of the original packaging remain unaltered and in good storage conditions, protected from extreme temperature and humidity .

1. 1 TECHNICAL DATA SHEET REABILITA CAL AC PURE NHL BREATHABLE FINISH WITH PHOTO - CATALY TIC PROPERTIES 1. DESCRIPTION REABILITA CAL AC PURE is a dry mortar, exclusively formulated from Natural Hydraulic Lime , intended for the execution of finishes with excellent permeability to vapour ideal for renovation and rehabilitation solutions of old coatings . This finish mortar , base d on lime , has got photo - catalytic prop erties enabling , in the presen ce of sunlight , dissocia tion of dirt , fung i and other organic and inorganic compounds present in the atmosphere, keeping surfaces clean and contributing to the reducti on of atmospheric pollution. In addition to these prop erties , the use of lime in its produ ction makes it possib le to associa te traditional lime c h aracter i stics, such as , high compatibili ty with old substrate s and excel l ent durabili ty , being ideal for rehabil itation, especially in areas whose effects of deposition of dust and pollution are more notorious, such as urban environments . These self - cleaning and decontamination features allow to reduce the need for maintenance . 2. FIELD OF USE REABILITA CAL AC PURE i s used as a finish in the maintenance and rehabilitation of buildings , n amely when external coatings of old building facades are intended to be rec overed , that require high levels of water vapour permeability . REABILITA CAL AC PURE constitu tes the final st age of the rehabilitation scheme of REABILTA CAL range . REABILITA CAL AC PURE may also be used on old re nders provided that they have the appropriate physical and mechanical maintenance conditions . It may also be applied in other coating systems , n amely E COC ORK RENDER and ECO CORK L IME . Since these are specific situations in each rehabilitation work, our Technical Services should be consulted at the time of product selection . 3.

2. 2 TECHNICAL DATA SHEET REABILITA CAL AC PURE NHL BREATHABLE FINISH WITH PHOTO - CATALY TIC PROPERTIES Adhesion to brick and block / Mode of fracture ≥ 0,2 MPa / A and B EN 1015 - 12 Modulus of elasticity 1750 - 2250 N/mm2 BS 1881 - 5 Density 1200 ± 150 kg/m3 EN 1015 - 10 Capil larity (24h) ≥ 0,3 kg/m2 EN 1015 - 18 Permeability to water vapour μ ≤ 15 EN 1015 - 19 Water penetration after capillarity test < 5,0 mm EN 1015 - 18 Reaction to fire Class A1 EN 988 - 1 Thermal conductivity 0,45 W/(m.K) (P=50%) NP EN 1745 4. APPLICATION a) Substrate preparation Substrate s prepared with REABILITA CAL RB mortar are ready to rece ive REABILITA CAL AC PURE . In case of direct application on another type of render, the latter should be regular, cohesive, clean and without any type of material that affects the normal adhesion conditions . b) Mortar preparation REABILITA CAL AC PURE should be mix ed with the appropriate quant ity of water (5,0 to 5,5 litres per 25 kg bag ), in small quantities and using an electric m ixer , so as to obtain a uniform and lump - free paste . Strict control of the mixing water is fundamental and decisive to ensure uniformity of mortar mix . c) A p plica ti on A fter mix ing , REABILITA CAL AC PURE should be applied in two successive layers . T otal thickness of the coating should not exceed 2 mm. Work joints should be resumed within a ma xim um period of 12 h ours . So as to minimiz e work joints , complet e panels should be carried out , whenever poss ible .
