BAGAR AIRLISS EXT

An exterior filler protects, evens out and decorates the façades or exterior walls of a building. It forms a protective layer against weather exposure such as rain, wind and temperature variations, while concealing irregularities in the substrate. Applying an exterior filler can also, in some cases, contribute to external thermal performance, or improve the durability of a bare wall.

Using a filler such as Bagar Airliss EXT, specially formulated for exterior substrates, delivers a regular, aesthetic result that meets strength and water-resistance requirements. This filler can be spray-applied with an airless machine for faster application and a uniform finish, even over large areas.

A well-chosen exterior filler extends the life of the building, enhances the appearance of the façade and provides an effective barrier against water penetration and dirt.

An exterior filler such as Bagar Airliss EXT is specially designed to withstand weather conditions while providing a durable, aesthetic finish. This type of filler can be applied to walls made of concrete, concrete block, brick, or old renders being renovated. It is formulated to bond strongly, cover substrate defects and provide a protective layer resistant to moisture and weathering.

Unlike an interior filler, it must meet specific requirements in terms of mechanical strength, water resistance and water vapour permeability. Bagar Airliss EXT combines these qualities with fast airless application, making it ideal for both new-build and renovation projects.

For an exterior wall, always choose a filler formulated for this type of environment, to guarantee adhesion, stability and long-term protection.

For a damaged exterior wall, use a repair-grade exterior filler capable of filling defects, concealing non-structural cracks and smoothing the surface before decoration. Bagar Airliss EXT is perfectly suited to this role. It can be applied in one or more passes to correct irregularities, while providing a clean, durable and decorative final result.

Thanks to its ready-mixed formulation, this filler requires no mixing and is applied directly onto a clean, dry substrate. It effectively treats damaged walls, whether concrete, cement or concrete block. Once sprayed, it can be smoothed and sanded if necessary to achieve a uniform appearance.

Choosing an exterior filler suited to repair work ensures good adhesion, durability against the weather, and a neat visual result, even on initially deteriorated substrates.

An exterior render is a preparation or finishing coating designed to protect and even out the substrate. It can be smooth, float-finished or spray-applied depending on the application method. Roughcast, on the other hand, is a specific type of render with a textured, granular finish, often used for decorative purposes.

In other words, roughcast is one possible finish of a render, generally achieved by spraying or with a Tyrolean gun, giving a rustic or textured appearance. A render itself can remain smooth or receive various types of finishes depending on aesthetic preferences.

With a product like Bagar Airliss EXT, you can achieve a smooth or semi-textured finish depending on the smoothing technique and tools used. It is therefore a versatile filler that can precede or replace a roughcast finish, while ensuring protection and a regular substrate.

Concrete block, being a raw and porous material, requires a suitable exterior filler to protect and decorate it. The filler must bond strongly, fill visible joints and provide a barrier against moisture. Bagar Airliss EXT is perfectly suited to this use: it effectively covers concrete block surfaces while making smoothing easier for a uniform result.

Thanks to its ready-mixed texture and easy airless spray application, it treats concrete block walls quickly and precisely. The filler evens out surface irregularities, conceals block joints and creates a surface ready to be painted or left as is.

Choosing a dedicated exterior filler such as Bagar Airliss EXT for concrete block walls guarantees adhesion, durability and aesthetics on an often irregular substrate.

An exterior filler such as Bagar Airliss EXT is designed to be resistant to liquid water while remaining permeable to water vapour. This means it effectively protects walls against rain, water splashes and ambient moisture, without preventing the natural release of vapour from inside the wall.

The water resistance of a filler depends on its specific formulation and applied thickness. Bagar Airliss EXT performs this function by forming a continuous protective layer that prevents water penetration and reduces the risk of mould or efflorescence.

Water resistance is therefore an essential property of a good exterior filler, but it must always be combined with good breathability to avoid long-term damage to the wall.

An exterior filler is not watertight in the strict sense, but it is water-repellent. This means it repels rainwater without blocking the water vapour escaping from the wall. This dual property is essential to prevent internal moisture problems and ensure the durability of façades.

Bagar Airliss EXT fully meets this requirement: it protects walls against the weather without sealing them completely. It allows the materials to breathe, which prevents condensation and structural damage.

A good exterior filler is therefore not fully watertight like a bituminous coating, but it provides sufficient protection against water while maintaining the building’s moisture balance.
