What should insulated facades be painted with?
Insulating a house is a rational decision that will help you save both heat and money. The main thing is that the completed work meets your expectations, and the new facade coating maintains its presentable appearance for a long time. What is needed for this and how to choose materials without making mistakes — experts advise.
Insulation Materials and Their Types
Today, two types of materials are used for exterior insulation of houses.
- Polystyrene foam (foam plastic). It is suitable for slabs, concrete, and brick. It retains heat well, provides sound insulation, and is cost-effective.
- Mineral wool. It creates a breathable coating, insulates perfectly, is fire-safe, and moisture-resistant. It costs more than foam plastic but is also more practical in terms of service life.
Each of these systems requires a final protective coating layer. Choose materials intended for exterior use on buildings, resistant to all weather conditions, and with good vapor permeability to allow the surface to “breathe.” This will eliminate the risk of mold formation, which can damage paint and ruin the coating.
Which Materials Are Suitable for Insulation Systems?
- Decorative plaster
- Textured paint
- Facade paints
When selecting materials, always pay attention to which surfaces they are designed for. Otherwise, the coating will not last long and you will have to redo the top layer of insulation.
Professional advice: Acrylic-based materials are suitable for foam plastic, while silicone-based materials are best for mineral wool. It’s important that all materials used in the system are of the same type. This way the surface will be strong and durable.
What Should You Choose?
If you have a private house and want not only to insulate it but also to update the facade beautifully, then you should opt for textured paint or decorative plasters:
- Textured paint allows you to create a three-dimensional pattern on the facade using special tools.
- Decorative plasters are easier to apply — a pattern appears on the wall in the process thanks to the grains in the material.
Why are these materials better for private homes? Such work is easier to carry out “from the ground,” and a good surface is well visible up close. 
As for apartment buildings, facade paint is the optimal option:
- If you didn’t manage to complete all work during warm weather, it’s better to use paint suitable for low temperatures. At temperatures down to -5 °C, All-Season Facade Paint TRIORA can be applied to cold surfaces. Additionally, two hours after application, the paint becomes resistant to precipitation, which is especially important in autumn.
- If you plan to insulate during warm weather, then classic facade paint can be used; it’s applied at temperatures from 5 to 35 °C.
For exterior work, it’s important to remember about surface preparation and improving material adhesion with the base. If using decorative textured materials, apply quartz primer as the first layer on foam plastic. For facade paint preparation, thoroughly prime with TRIORA waterproofing primer.
All TRIORA facade materials come in both acrylic and silicone bases. They create a wear-resistant vapor-permeable coating that lasts on average from 8 to 15 years depending on application quality and weather conditions affecting the surface.
If you perform all finishing work on your insulation system according to rules and recommendations, your house will receive high-quality additional protection and maintain an attractive facade for many years.
