The crazing of the exterior paintwork<\/strong> is a common problem affecting facades, terraces, roofs and other surfaces exposed to the elements. Over time, the paint begins to crack and flake off in small fragments, leaving the surface unprotected and exposed to deterioration. Although this is a common phenomenon, it is not inevitable: with the right treatment and products such as a quality primer<\/strong> and in case of facades apply Tecno Prodist Termoimper<\/a><\/strong> or on terraces elastic waterproofing Imper Antigoteras by Tecno Prodist<\/a><\/strong>It is possible to prevent it and to keep surfaces intact for years to come.<\/p>\n\n\n\n

Why crazing appears on exterior paintwork<\/strong><\/h2>\n\n\n\n

Crazing is mainly caused by a combination of climatic factors and surface preparation problems. Sudden changes in temperature cause expansion and contraction of the materials, which leads to stresses in the paint. If the paint is not flexible enough, it will eventually crack.<\/p>\n\n\n\n

Other factors favouring crazing are:<\/p>\n\n\n\n

    \n
  • Use of low-quality or unsuitable paints for exteriors.
    <\/li>\n\n\n\n
  • Lack of primer on porous or poorly adhering surfaces.
    <\/li>\n\n\n\n
  • Application of paint on dirty, wet or deteriorated surfaces.
    <\/li>\n\n\n\n
  • Prolonged exposure to UV rays, humidity and heavy rain without an effective protective coating.
    <\/li>\n<\/ul>\n\n\n\n

    How to prevent paint cracking<\/strong><\/h2>\n\n\n\n

    The key to preventing crazing is good preparation and the choice of materials that will withstand the environmental conditions. First of all, it is essential to clean the surface by removing dust, grease, loose paint or contaminants. If the substrate is very porous or has adhesion problems, apply a primer such as Tecpint Primer<\/strong> will ensure that the topcoat adheres properly.<\/p>\n\n\n\n

    The next step is to apply a coating that combines elasticity, waterproofing and weather resistance. This is where Tecno Prodist Termoimper <\/strong>for the painting of facades and the Imper Antigoteras by Tecno Prodist<\/strong>an elastic rubber-based waterproofing that adapts to the natural movements of the surface without cracking in the case of terrace floors, always with porous substrates.<\/p>\n\n\n\n

    Imper Antigoteras: elastic and long-lasting protection<\/strong><\/h2>\n\n\n\n

    Imper Antigoteras<\/strong> creates a continuous, flexible and resistant film that acts as a barrier against water, UV rays and temperature changes. Thanks to its formulation, it not only prevents leaks and dampness, but also protects the paint layer against wear and tear and stresses that cause cracking.<\/p>\n\n\n\n

    Its application is simple: the substrate where it is applied must be porous, not being for example suitable on ceramic substrates, once the substrate is clean and dry, a first coat is applied undiluted, it is left to dry for 3 to 4 hours and a second coat is added, to reinforce the waterproofing a third coat of the product can be applied leaving the same drying time. The result is a satin finish, free of tackiness, which maintains its integrity even in areas with extreme weather conditions. Very similar process in the case of fa\u00e7ade painting using Termoimper<\/strong>This product will also provide extra thermal insulation for your home.<\/p>\n\n\n\n

    Long-term maintenance<\/strong><\/h2>\n\n\n\n

    Although the Imper Antigoteras or Termoimper<\/strong> offer long-lasting protection, it is advisable to check the surfaces from time to time for any signs of wear. Regular cleaning and immediate repair of small cracks will prevent the problem from worsening.<\/p>\n\n\n\n

    Investing in quality products from the start not only prevents cracking, but also reduces maintenance costs and extends the life of the painted surface.<\/p>\n\n\n\n

    Conclusion<\/strong><\/h2>\n\n\n\n

    Crazing on exterior paint is a preventable problem if the right products and processes are chosen. By combining a quality primer with the elastic waterproofing Imper Antigoteras by Tecno Prodist<\/strong> or in case of facades Tecno Prodist Termoimper<\/strong>It is possible to protect facades, terraces and roofs against water, sun and temperature changes, keeping the paint intact for many years.<\/p>","protected":false},"excerpt":{"rendered":"
