The products from the Paulin elastomeric line are the most effective and efficient solutions for the cladding and rehabilitation of wall surfaces which has been degraded by the presence of cracks and fissures.
THE BUILDINGS’ INJURIES: in buildings, injuries can normally be caused by external or internal factors.
Most common external factors:
• foundation collapse;
• concentration of loads;
• continuous vibrations.
Most common internal factors:
• withdrawal or expansion of materials;
• chemical reactions.
The lesions can be caused by the variation of the humidity within the building elements, or by the temperature variation. All these factors can cause more or less important injuries to the structures or individual elements of the building, favoring the entry of moisture, which accelerates the deterioration and aging of the entire structure.
Paulin elastomeric cycles are the best solutions for restoring damaged facades injured by plastic shrinkage cracks in plaster. The products from that collection, inserted in different cycles, can solve the most critical situations. The entire line is completed by the following complementary products:
• Sigilgum extra: stucco based on elastomeric resins for filling cracks.
• Poliflex: non-woven fabric obtained from thermoplastic propylene filaments fixed with stitches.
• Cracking net: glass fiber tissue for the reinforcement of sealings.
• Elastomedio: water-based fiber as a base for walls.
• Elastoras: continuous smoothing substance for wall surfaces affected by cracks due to the plastic shrinkage of the plaster.
Class A1 cracks < 100 μm (0,10mm)
They are very thin and small cracks difficult to see because they only affect the upper part of the plaster. Usually they can be noticed while wetting the surface and they seem a very fine cobweb.
Classe A2 cracks < 250 μm (0,25mm)
They are evident when a wet wall begins to dry out, because water penetrates deeper into the cracks and then dries later. The cracks appear reticular in shape and are generally very fine. This cracks normally have a size of about 20cm and affects more the external part of the plaster and less the internal one. This is generally caused by bad construction or inadequate application of the plaster.
Class A3 cracks < 500 μm (0,50mm)
They normally affect the plaster or the superficial part of the concrete. They are caused by shrinkage during the setting phase and can be 3 to 15mm deep.
Class A4 cracks < 1250 μm (1,25mm)
These are important cracks, they can have linear paths and they often affect the structure too. They facilitate the rainwater infiltrations.
Class A5 cracks < 2500 μm (2,5mm)
They normally affect the structure and are caused by different expansions between the various construction materials or structural failures. Before intervening, check that the phenomenon has been stabilized and that the causes have been solved.
The changes in temperature, the erosion of atmospheric agents and the application on the facades of products with poor mechanical properties, favor the appearance of lacerations in the plaster, more or less deep, which become the easiest ground for the attack of mold and the penetration of water and aggressive substances. This situation, in the long run, leads to the disintegration of the materials and consequently to the reduction of the insulating power of the wall, with serious damage for the masonry and therefore the safety of the entire building. The chemical composition of the Paulin line has very stretchy and waterproof elastomeric resins that effectively solve these problems, restoring damaged parts with an impeccable covering effect and restoring stability and aesthetic value to the support.
NO ATTACK FROM THE OUTSIDE
The elastomeric coatings from Paulin’s line form an external covering film that allows to perfectly mask and heal the damage to the support. Their elasticity does not fear the low or the high temperatures, for this reason, once applied they guarantee uniformity and resistance to any external stress and attack. They also have important characteristics of water repellency and impermeability, which prevent water from penetrating with an increase in insulating power. Finally protected from aggression and restored by the old cracks, the facades treated with the Paulin elastomeric line rediscover all their ancient splendor.
The proposed intervention of restoration, if applied, may cover, following the intended procedure, the risks caused by product defect or installation, with the "posthumous special risk policy No. 22002" stipulated by us with the company AXA INSURANCE.
