ITProtecting and maintaining a façade after renovation: the right solutions
A renovated façade is not a façade protected for good. Within weeks of the work finishing, the attacks resume: rain, damp, air pollution, biological growth, graffiti. Without suitable protection, even a recent renovation deteriorates within a few years.
The good news is that with the right products applied at the right time, you can extend the life of a façade and reduce maintenance costs. A masonry sealer, a coloured sealer or an anti-graffiti coating, chosen to suit the substrate, makes the difference.
Why protect a façade after renovation?
Even after renovation, a façade remains exposed to permanent causes of deterioration: driving rain and damp, air pollution, biological growth on shaded elevations, and graffiti in urban areas.
Protection against water and damp: masonry sealers for façades
Water is one of the main causes of façade deterioration. Water ingress, green growth, efflorescence and cracking are often caused by excessive moisture absorption. To preserve the life and appearance of the materials, applying a water-repellent sealer is an effective solution. These products create a protective barrier against water while letting the substrate breathe, which avoids damp-related problems such as render coming away or mould growth.
There are several types of water repellent to suit different substrates and environments:
SCALPFUGE 35 : an invisible brick, stone and concrete sealer designed for porous materials. Thanks to its formulation, it penetrates deep into the substrate and stops water getting in, while keeping the natural look of the material. Ideal for façades that need to keep their original appearance with no film-forming effect.
SCALPFUGE EKO’R : a water-based water repellent formulated from plant-based, bio-based raw materials. It offers effective protection against water with a lower environmental impact, which makes it an excellent choice for projects where environmental footprint matters.
Please note: water repellents must only be applied to bare, porous substrates such as stone, brick or concrete. They are not suitable for painted surfaces.
Coloured sealers: tint and protect a façade in a single operation
When a stone, brick or concrete façade loses its colour, it can be brought back to life without repainting. Unlike conventional paints, coloured water repellents do not form a surface film but penetrate deep into the material, giving a dual action: tinting the façade while protecting it against water and damp for the long term. Suitable only for bare, porous substrates, these products preserve the natural look of the material while improving its resistance to weather and ageing. On brickwork, the result is a brick tint rather than a painted finish.
SCALP HYDROCOLOR PAE: ready-to-use tinted water repellent
SCALP HYDROCOLOR PAE is a ready-to-use tinted water repellent, available in four shades: Slate, Anthracite Grey, Sienna and Brick Red
It gives fast, even water repellency and a uniform finish. Specially designed to protect and enhance façades and roofs, it penetrates deep into the substrate while letting it breathe, which prevents water ingress and reduces the risk of cracking. Its coloured formulation revives and evens out the appearance of treated surfaces while giving effective protection against damp, weather and premature ageing. Ideal for stone, brick or concrete.
Coloured Water-Repellent for Roof & Facade – SCALP HYDROCOLOR PAE
SCALP HYDROCOLOR PAE is a ready-to-use, water-based 2-in-1 coloured water repellent designed to protect roofs and facades while enhancing their natural colour. Its advanced formula penetrates deeply to form an invisible, breathable barrier against water, freeze/thaw damage, urban pollution, and biological growth, without altering the material’s appearance.

Anti-graffiti protection: keeping a façade clean
In urban environments, graffiti and fly-posting are a constant threat to the appearance of façades. Two levels of protection are available depending on the degree of exposure and the maintenance regime.
VERNAEAU PU 16 – Permanent anti-graffiti coating
VERNAEAU PU 16 is a permanent anti-graffiti coating based on a water-based polyurethane resin, ideal for porous surfaces such as concrete, stone, brick or timber. Available in a matt or gloss finish, it gives long-lasting protection against graffiti. Its microporous formulation lets the surface breathe while offering excellent resistance to UV and abrasion. It is suitable for both interior and exterior use.
Please note: do not apply to marble or polished surfaces.
Permanent anti graffiti coating – VERNAEAU PU 16
VERNAEAU PU 16 is a professional-grade, permanent anti graffiti coating designed for porous surfaces both indoors and outdoors.

Maintaining the façade over time
A recently renovated façade needs regular maintenance to keep its original appearance and extend the life of its coating. Without it, the build-up of dirt, atmospheric pollutants and micro-organisms is likely to spoil its appearance and damage it. Proper facade maintenance keeps the protection you have applied effective and durable.
It relies on periodic cleaning to remove pollution deposits and dirt, and, where necessary, reapplying a protective treatment to keep the coating in good condition.
