Professional Check List Problems and solutions:
    • Waterproofing façades
      Protection for exterior walls: Waterproofing façades
      X
      Façades often have problems of infiltration associated with the appearance of cracks and
      fissures which may have different causes.


      Solution: proper cleaning of the façade and treatment of cracks and fissures followed by
      High-adherence waterproofing and reinforcing primer and waterproof elastic membrane, even at low temperatures.

    • Consolidating damaged walls
      Protection for exterior walls: Consolidating damaged walls
      X
      Over time damp ends up cracking paintwork, bringing down wall coatings and damaging stucco or rendering. As well as affecting the appearance of surfaces, this also diminishes the degree of comfort in a house.

      Solution: clean and if necessary renew the surface, applying a primer which penetrates in depth, consolidates surfaces, provides waterproofing treatment and gives excellent adherence for exterior paint.

    • Preventing and treating efflorescence
      Protection for exterior walls: Preventing and treating efflorescence
      X
      Saltpetre forms inside alkaline walls due to the combined effects of damp and bacteria. It appears on the surface in the form of saline stains and efflorescence which damages paint and rendering, causing ongoing deterioration of the wall surfaces.

      Solution: remove the efflorescence and material in poor condition and renew the wall;
      apply a 3 in 1 treatment to consolidate the wall (primary effect), repel damp and stop saltpetre appearing (waterproofing effect) and combat the fungi and bacteria which cause the saltpetre to form.
    • Removing moss
      Protection for exterior walls: Removing moss
      X
      Moss, lichens and algae proliferate in damp, porous materials, affecting their natural appearance
      and harming them.

      Solution: remove thick patches of moss with a spatula and, in dry weather, brush or spray on an anti-moss treatment in the affected areas in order to stop them reappearing.
    • Waterproofing porous materials
      Protection for exterior walls: Waterproofing porous materials
      X
      Most of the materials used for building are porous, with interconnected cavities through which
      water ends up passing and getting inside the building. This is the case with façades covered in
      porous materials (stone or ceramic tiles, for example).

      Solution: use an invisible water repellent, which forms a film while preserving the natural
      appearance of the materials.
    • Painting walls in contact with the ground
      Protection for exterior walls: Painting walls in contact with the ground
      X
      Walls and structures in contact with the ground are exposed to the effects of rain and irrigation water which rises up by capillary action. Where the foundations are not properly damp-proofed, buried walls and structures are also exposed to the action of damp under pressure.

      Solution: use a waterproof decorative paint, which adheres to damp surfaces, is microporous and resistant to the pressure of water behind it.

    • Preventing and treating damage to walls by damp and/or saltpetre
      Protection for interior walls: Preventing and treating damage to walls by damp and/or saltpetre
      X
      Saltpetre forms inside alkaline walls due to the combined effects of damp and bacteria. It appears on the surface in the form of saline stains and efflorescence which damages paint and rendering, causing ongoing deterioration of the wall surfaces.

      Solution: remove efflorescence and material in a poor state and renew the surface;
      apply a 3 in 1 treatment to consolidate the wall (primary effect), repel damp and stop saltpetre appearing (waterproofing effect) and combat the fungi and bacteria which cause the saltpetre to form.
    • Anti-damp treatment
      Protection for interior walls: Anti-damp treatment
      X
      Walls and ceilings exposed to the effects of damp develop marks and mould, and paint flakes off and wall coatings, stucco and rendering come loose. The cause of the damp must first be removed. If the wall is to be painted with a latex paint or re-rendered, the surface must first be treated with a primer which acts as a barrier against any damp which might appear. Alternatively, a damp-proof microporous paint can be applied directly.

      Solution: treat the surface with a consolidating, damp-repellent primer. Then paint with latex paint or apply the coating. A decorative damp-proof microporous paint can be also applied directly.

    • Waterproof coating for flat and sloping roofs
      Protection for flat and sloping roofs: Waterproof coating for flat and sloping roofs
      X
      Flat and sloping roofs, as they are exposed to rain, ultraviolet rays and sometimes have air-conditioning equipment mounted on them, are prone to the appearance of fissures and points where water can get in. Also, the cement-based mixtures used to build them are porous.

      Solution: after proper cleaning and treating the fissures, apply the elastic waterproof coating with filling function, proof against standing water and with maximum resistance to exposure to the sun. It is suitable for both flat and sloping surfaces. On damaged or absorbent surfaces, it is recommended that a primer be applied first in order to consolidate the surface and improve the adhesion of the waterproof coating: Rubson Primer FF2000 high-adherence waterproof, consolidating primer and Rubson Liquid Silicon SL 3000 elastic waterproof coating.
