Preventing On-Site Issues: CAP Arreghini’s Solutions
In exterior finishing, preventing on-site issues means safeguarding the appearance, performance and durability of surfaces over time. Among the most common challenges are the formation of mould and algae, the appearance of surface micro-cracks, and the detachment of either the finish coat or the entire application system. If not addressed correctly, these issues can quickly compromise the quality of a facade and lead to increasingly frequent maintenance interventions.
To prevent and mitigate these critical issues, CAP Arreghini has developed dedicated solutions engineered to deliver long-term protection. Highly breathable paints and coatings, combined with anti-algae and anti-mould systems, help keep surfaces protected and resistant to weathering. At the same time, elastomeric products and highly elastic finishes help minimise the formation of micro-cracks and surface crazing, preserving the uniformity, integrity and aesthetic quality of facades over time.
This system-based approach enhances the durability of the intervention while maintaining the long-term appearance of exterior surfaces.
When Issues Arise – And How to Prevent Them
Problems affecting exterior surfaces may occur both during application and throughout the service life of the facade as a result of weather exposure, environmental conditions and substrate characteristics.
Mould and algae generally develop gradually and become visible on the finish coat, particularly in environments with high humidity, challenging building exposure or insufficiently protected substrates. Surface cracking and coating detachment, on the other hand, may originate from substrate conditions or from an incorrectly specified or executed application system. In these cases, the defect may affect the primer, the finish coat or the entire coating system, compromising both the appearance and long-term durability of the facade.
For this reason, substrate preparation is one of the most critical stages of the entire intervention. A thorough assessment of the surface, combined with the selection of the most appropriate application system, significantly reduces the risk of future defects while improving long-term performance.
Thanks to a comprehensive portfolio of dedicated systems, CAP Arreghini supports professionals in delivering reliable, durable and high-performing coating solutions. The use of purpose-designed products within compatible systems ensures greater continuity between primer and finish, improving adhesion and enhancing the overall resistance of the coating.
Long-Lasting Aesthetics
Exterior surfaces are constantly exposed to weathering and, over time, may develop alterations that affect their visual appearance. The most common issues include staining caused by mould and algae growth, surface irregularities, micro-cracking and the gradual loss of colour uniformity.
These phenomena not only compromise the facade’s appearance but may also require costly maintenance interventions.
Achieving stable, long-lasting aesthetic performance begins with the earliest stages of the application system. Selecting products specifically suited to both the substrate and the intended application is essential for delivering lasting aesthetic quality alongside reliable technical performance.
Fasadecap and Sanacap: Integrated Systems for Surface Protection
CAP Arreghini has developed dedicated solutions designed to prevent the most common forms of surface deterioration. Through its Fasadecap and Sanacap product lines, the company offers a complete range of systems for protecting, restoring and enhancing virtually every type of surface.
Within the Fasadecap range, siloxane systems provide an effective solution for improving facade protection against weathering. These professional coatings combine excellent exterior colour stability with outstanding hiding power and strong adhesion across a wide variety of substrates.
Among them, Sil96 Active offers an excellent balance of technical performance, reliability and aesthetic quality. Thanks to its high breathability and low water absorption, the system helps prevent the growth of mould and algae, maintaining cleaner, healthier and more uniform surfaces over time.
Other finishes within the range – including Elasto Active, Elasto Stucco and Gum Tecnocap – are specifically designed to limit the propagation of micro-cracks while increasing surface protection, enhancing both aesthetic continuity and the long-term durability of the finish.
For issues specifically related to mould, algae and condensation, the Sanacap range provides dedicated solutions for remediation and prevention in both interior and exterior environments.
The range includes sanitising treatments, anti-mould paints and specialised additives developed to improve indoor environmental quality while preserving the long-term appearance of wall surfaces. Products such as Gradiente Active, Sana Active, My Weiss Active and Okapa W have been formulated to restore optimal substrate conditions and prevent future deterioration by effectively addressing moisture-related issues, biological contamination and staining of various origins.
Preventing the primary causes of surface deterioration means enhancing the long-term value of the entire finishing intervention.
Selecting the most appropriate application system together with purpose-designed products helps preserve protection, aesthetic uniformity and surface durability over time, reducing maintenance requirements while protecting the value of the building itself.
