Summer Weather Conditions and Protection of Building Materials

During the summer, building materials are exposed to extreme conditions: intense UV rays, violent storms, dust, and pollutant deposits.

Without proper protection, surfaces deteriorate quickly. This is where SCALP comes in, offering products specifically designed to prevent, treat, and preserve sensitive surfaces over the long term.

1. Summer storms and rain: moisture infiltration and material degradation

Summer is not only synonymous with sunshine; it also brings intense, sometimes sudden storms. These brief but heavy rainfalls challenge building materials, especially when they are porous or insufficiently protected. Alternating periods of high heat and heavy precipitation create an environment conducive to invisible short-term damage, which can lead to serious medium- and long-term consequences.

Perfect conditions for biological growth

Façades, roofs, pavements, and baseboards absorb moisture after every rainfall. This retained moisture can lead to:

  • The proliferation of microorganisms (moss, green algae, lichens, fungi), particularly on north-facing or shaded surfaces.

  • Progressive degradation of joints and mineral surfaces weakened by water infiltration and repeated drying/heating cycles.

  • Silent leaks that can penetrate coatings or masonry into interior walls, causing stains.

In urban, rural, or coastal areas, this phenomenon is amplified by ambient humidity, air pollution, and dust, which serves as a substrate for parasitic vegetation.

ANTI-M EKO’R is the ideal preventive treatment for protecting roofs, façades, and other exterior surfaces against algae, lichens, and organic/biological growth. Made from bio-based raw materials, it offers an environmentally responsible alternative to conventional products. Its preventive action creates an invisible barrier that stops green staining from appearing, helping surfaces maintain their clean, natural look. Suitable for tile and slate roofs as well as stone, brick, and rendered façades, this treatment is compatible with a wide range of mineral substrates. Solvent-free and free from harmful substances, ANTI-M EKO’R extends the lifespan of surfaces by limiting biological fouling, reducing the need for aggressive cleaning or heavy restoration work in the future. It can also be applied by drone, ensuring fast, consistent, and safe application—especially useful for large areas or hard-to-reach surfaces.

Why treat in summer?

  • Microorganisms settle when heat follows rainfall: treating in summer prevents long-term proliferation in autumn.

  • Acting quickly preserves the aesthetic appearance of façades and roofs and avoids costlier interventions such as scraping, joint repairs, or rehabilitation.

  • Reduces the risk of coating detachment or plaster weakening due to water saturation.

2. Summer pollution and urban dust

Summer is also the season when atmospheric pollutants accumulate on façades. Long dry periods combined with increased human activity (road traffic, construction, outdoor events) favor the deposition of greasy particles, fine dust, and soot.

Discreet but harmful accumulation

High temperatures intensify the impact of urban pollution on buildings:

  • Greasy dirt from traffic and volatile pollutants.

  • Sticky dust that adheres to heated surfaces.

  • Soot and combustion residues from traffic or summer barbecues.

  • In some areas, deposits from pollen, dry leaves, or construction dust.

This “dry” pollution alters the aesthetic appearance of materials (faded colors, streaks, stains) and can promote later microbial growth if not cleaned regularly.

SCALP FACANET PAE – Façade, roof, wall, and floor cleaner without rinsing

3. Sensitive surfaces: simplifying maintenance with smart products

Some architectural structures or public buildings are located in hard-to-reach areas, subject to specific conditions (pedestrian zones, high elevations, sensitive environments), or must meet strict cleaning and durability requirements with minimal intervention.

In these cases, traditional maintenance becomes burdensome. Professionals increasingly seek intelligent, long-lasting, and autonomous solutions.

SCALP CONSOLIDANT HYDROFUGE – Mineralizing and hydrophobic in one application

SCALP CONSOLIDANT HYDROFUGE is a 2-in-1 treatment that both mineralizes and waterproofs, strengthening the structure of materials and effectively protecting against moisture.

It penetrates deeply into porous substrates such as limestone, siliceous stone, brick, concrete, and mineral plasters, hardening and stabilizing the material while preventing water infiltration. Its non-filming formula allows the surface to breathe, promoting water vapor release essential for long-term durability.

Invisible after application, it preserves the natural appearance of surfaces without shine or color change. Ideal for historic façades, protected buildings, or sensitive, hard-to-reach surfaces where maintenance should be minimal.

Important note: For optimal penetration and maximum effectiveness, a thorough surface cleaning is recommended before application.

 

Summer poses specific challenges in the construction sector: intense UV radiation, sudden rainfall, urban dirt, limited accessibility, and reduced maintenance. SCALP offers technical solutions adapted to these conditions: transparent or pigmented water repellents, powerful cleaners without rinsing, rapid biocidal treatments, or self-cleaning coatings. These products allow risks to be anticipated, reduce interventions, and extend the durability of buildings while preserving aesthetics and saving time.
