The façade renovationIt's the very face of your house that's being played. Between the various possible solutions, one question often comes up: do we have to opt for a facade paint or facade coating? These two options meet distinct needs and constraints, with impacts on the aesthetic aspect, weather protection and sustainability, especially in our southern regions between Alpes-Maritimes and Var. Understanding their differences, advantages, limitations and application contexts will allow you to make an informed choice depending on the nature of your support (concrete, brick, stone, parpaing) and your expectations in terms of rendering.
Front and facade paint: definitions and uses
Before comparing their effectiveness, it is essential to clarify what is involved in a outside paint and one coated applied on a south house facade. Facade painting means a coloured liquid coating intended to revive the walls, mask from small superficial imperfections and protect against pollution or early signs of climatic wear and tear. Paintings acrylics, Fliolites, Siloxanes or Minerals are among the most common, each adapted to specific contexts.
Lfacade coating, also called cream, goes further: applied in thick layer, it repairs, uniforms and waterproofing the wall surface. The coating is used to mask marked defects, improve (modestly)thermal insulation, and offer aesthetic finishes various: taloché, scratched, smoothed or rustic. There are different types of coatings based on lime, cement or plaster depending on the region and type of facade.
Advantages and disadvantages: facade painting versus facade coating
Choosing between these two solutions requires understanding their strengths and limitations. Their performance is assessed in relation to power to cover, atadhesion on the support, the longevity and level of protection offered for each facade house south.
What are the strengths of facade painting?
The facade paint appears as a quick and affordable solution when the wall is in good condition. It guarantees a wide choice of shades and allows to play on visual effects at lower cost. If you would like to see the final result of these interventions, you can consult examples of front/post façade transformation.
| Type of paint | Water resistance | Power to cover | Adaptation support |
|---|---|---|---|
| Acrylic | Good | Medium/High | Concrete, brick, parpaing |
| Pliolite | Very good | Medium | Crude facades, old |
| Siloxane | Excellent | High | Renovation, wetlands |
| Mineral | Variable | Medium | Natural stone |
The painting facade remains ideal when it comes to quickly bringing a new coloration or modernising a facade without structural intervention. It guarantees a wide choice of shades and allows to play on visual effects at lower cost.
What are the notable advantages of facade coating?
Lfacade coating adds a higher restorative and protective dimension. For an old house with micro cracks or irregularities, this thick covering corrects the defects of the frame, promotes the waterproofing and secures the durability of the support in the face of the typical climatic aggressions of the facades in the south. The finishing possibilities – tapped, scratched or projected – offer a range of customizable aspects, from local tradition to contemporary spirit.
More and more owners opt for natural alternatives. For example, mineral paints and coatings made up of natural materials allow excellent breathability and ensure optimal regulation of wall moisture.
Constraints to consider before choosing
The exterior paint requires careful preparation: no lasting adhesion on a friable wall. The facade coating involves heavier work and a higher cost. To anticipate your expenses, it is recommended to consult the price renovation facade 83 and 06 practiced by local experts.
Lfacade coatingIt involves heavier work, higher cost and sometimes longer lead times. Its installation requires technical expertise, especially to guarantee the hang on old or mixed supports (stone + bricks). A less punctual but more complex maintenance may also be imposed on certain mosses or dirt caused by exposure.
How to adapt the choice to the type of support and climate?
The support directly conditions the choice of facade coating ideal. Let your façade be in concrete, stone, brick or parpaing, each solution has its technical recommendations to ensure the best fit in time.
What to recommend for a concrete or parpaing facade?
For a recent wall in concrete or parpaing, healthy and unlikely to move, facade paint (including acrylic or siloxane) is perfectly suitable as long as the level of protection does not require deep treatment. Lcoated consider if you want to completely modify the original appearance of the wall and erase apparent joints or roughnesses caused during mounting.
Prefer a breathable facade coating and flexible when construction dates back several decades. Old parpaing houses sometimes deserve a armed coated to prevent the recurrence of cracks.
Why does stone or brick require special precautions?
The selection between coating or external painting depends on several parameters: the state of the support, the location (proximity of the sea, southern exposure) and the desired rendering. To ensure the success of your work, ask for advice from a professional fascidier in the South, accustomed to diagnosing the specifics of the facades of the PACA region.
In both cases, testadhesion of the product or applying a specific primary ensures a lasting result. The renovation of these supports must follow the logic of the old building and preserve a minimum ventilation of the wall to avoid any future pathology.
What criteria should be taken into account to make the right choice?
Selection between coated or painted outside depends on several parameters to be evaluated carefully. Beyond the budget, ask yourself about:
- General state of support (healthy, cracked, dusty...)
- The location of the house (proximity of the sea, south exposure, significant temperature variations...)
- The type of rendering desired (soft, textured, traditional, modern...)
- Future maintenance (cleaning frequency, retouching, biological resistance...)
- Your desire to strengthen thermal insulation without launching a complete ITE
Ask for advice from a local professional, who is used to diagnosing the specifics of facades house south and put the right product on the right support.
In any case, prefer a rigorous preparation : high-pressure cleaning, precise plugging of cracks, anti-foam treatment. This floor will guarantee the real life of the painting or fromcoated. Also remember to integrate any local obligations (imposed colors, protected areas).
Frequently asked questions about the choice of paint and coating for facade
Which solution to choose to renovate a cracked facade?
For a façade with many cracks or significant irregularities,facade coating based on lime or cement remains the most effective solution. Indeed, it masks these defects, strengthens the waterproofness and rejuvenates the overall appearance of the wall. The painting only will fit the hair cracks and on an already healthy support.
- Coated for damaged walls
- Paint adapted only if irregularities are slight
What types of paints are used according to the façade exhibition?
According to the exhibition, there are several options: facade house south, the Siloxane paint offers optimal protection against moisture and UV rays. Lacrylic adapts well in temperate zones and resists pollution. The Fliolite will be preferred in urban or coastal areas, thanks to its ability to repel water and limit infiltration.
| Exposure | Recommended paint type |
|---|---|
| Sun & humidity | Siloxane |
| Urban pollution | Pliolite |
| Moderate climate | Acrylic |
Does the coating contribute to the thermal insulation of the house?
Lcoated only slightly improves thermal insulation thanks to its thickness and its ability to remove some thermal bridges. However, it does not replace a real outside thermal insulation (ITE). For optimal comfort, combine the coating with a dedicated insulation solution, if it meets your energy or regulatory objectives.
- Slight improvement thanks to thick coatings
- Limited efficiency compared to an ITE system
What are the average drying times for each type of coating?
The drying time vary depending on the surface and weather conditions. The facade paint usually dry in a few hours to be dust-free, but sometimes it takes 24 to 48 hours for complete drying. Lfacade coating often takes several days before being completely watered, especially for Traditional or lime coated.
| Coating | Average drying time |
|---|---|
| Acrylic paint | 4-6 hours/without dust, 24 hours complete |
| Siloxane paint | 5-8 hours/without dust, 36 hours complete |
| Lime/cement coating | 3-7 days according to thickness |
