Protecting facades from sun and cracks

How to protect the facades in Marrakech from the sun, heat and micro cracks

Introduction

The protection of facades in Marrakech In a city where temperatures regularly exceed 40°C, where the sun is present almost all year round and where thermal variations weaken the materials, the facades are put to great test. As a result, discoloration, de-clustering, micro-cracks, water infiltration, loss of aesthetics and a decrease in real estate value.

The Marrakchi architecture — between modernity, clean lines and traditional heritage — requires materials that resist the local climate. Moreover, in a market where facades play a key role in the image of a villa or riad, their regular maintenance is indispensable.

In this article, we examine the causes of deterioration of the facades in Marrakech, the effective techniques to protect them, the materials to be preferred, the common mistakes to avoid and the solutions proposed by SECOND WORLD to ensure a durable, aesthetic and resistant facade.

1. Why are the facades so fragile in Marrakech?

The intense sun and the powerful UV

Marrakech enjoys an exceptional sunshine:

• more than 300 days of sunshine per year,

• direct exposure to UV radiation,

• a strong reflection of light on clear soils.

Consequences:

• tarnishing of colours,

• premature degradation of paints,

• deterioration of coatings,

• expansion of materials.

High heats and thermal variations

Temperatures may exceed 45°C in summer. At night, they sometimes fall by 15°C.
The materials are subjected to:

• thermal expansion,

• contraction,

• formation of micro cracks,

• Gradual weakening of coatings.

The ubiquitous dust

The semi-desertic climate of Marrakech results in:

• dust deposits on the facades,

• accumulation in microcracks,

• rapid soiling of coatings.

The facade loses its color and seems to age faster.

Heavy but point rains

Although rare, rains can:

• Infiltrate micro cracks,

• cause the detachment of the coating,

• create aureoles and moisture stains.

2. What solutions to protect the façades in Marrakech effectively?

1. Use a quality monolayer coating

The monolayer is one of the most used solutions in Morocco because:

• It resists the heat very well,

• it offers a good seal,

• it protects against micro-cracks,

• It offers aesthetic finishes (gratty, taloché...).

SECOND WORK uses products specially adapted to the Marrakchi climate.

2. Apply UV-resistant outdoor paint

A well-protected facade must:

• keep its colour,

• resist UV radiation,

• offer an additional moisture barrier.

High-strength acrylic or siloxanes paints are ideal for Marrakech.

3. Opt for mineral or silicate coatings

These coatings:

• are microporous,

• let the wall breathe,

• protect from moisture,

• are very resistant to the sun.

4. Verify and strengthen external insulation

The external insulation allows to:

• limit thermal expansion,

• reduce micro cracks,

• improve interior comfort,

• reduce energy consumption.

5. Apply anti-crack treatment

Elastomer or armed products:

• absorb the movements of materials,

• fill the micro cracks,

• extend the life of the façade.

3. Protecting facades from micro-cracks: causes and solutions

The main causes of micro-cracks

• Heat and expansion of materials

• Improper application of coating

• Poor quality of products

• Subsidy of support

• Sudden thermal shocks

• Building movements

Solutions to avoid micro-cracks

• Apply an armed coating

Adding a fiber or weft to strengthen the resistance.

• Use a hanging primary

Improves cohesion and avoids detachments.

• Respect drying times

Essential to ensure a correct intake of the monolayer or coating.

• Control wall moisture

A damp wall weakens the entire facade.

• Make expansion joints

Mandatory in certain architectural configurations.

4. How to preserve the colour and aesthetics of the facades in Marrakech?

1. Choosing climate-friendly shades

Tones used in Marrakech — sand, beige, ochre, off-white —
are more resistant to discoloration.

2. Apply a water repellent facade

Hydrorefuge allows to:

• Repelling water,

• limit stains,

• reduce the appearance of mould,

• keep the original color longer.

3. Regular but non-abrasive cleaning

To avoid:

• scratches,

• surface damage,

• Degradation of coating.

4. Anticipate minor renovations

Early retouching avoids major degradation.

5. Errors to be avoided absolutely when protecting a facade

1. Apply a coating or paint in full sun

The material dries too fast → cracks and differences of colour.

2. Choose a low-end product

Poor UV resistance, reduced durability.

3. Neglect the preparation of the support

Poorly cleaned wall = insured release.

4. Do not treat microcracks before painting

The paint doesn't solve anything and the crack reappears very quickly.

5. Place on a damp wall

Provoque décolletation, stains and fragilization of the entire facade.

SECOND WORK guarantees a rigorous methodology and suitable materials.
