Insulated facades are practical, economical and profitable. However, this rational investment can be reduced to zero easily by choosing the inappropriate paint for your insulation system. How to avoid mistakes? Which façade paint would be suitable exactly for you? We share the experience of professionals.
Prepare your house for the heating season in summer
Today, foam plastic and mineral wool are the most popular materials for facades insulation. Both of them have important advantages and, with properly carried out, help to warm the house.
Foam plastic:
- Easy;
- Does not absorb moisture after precipitation;
- Plates create a thick layer of coating;
- The material is relatively inexpensive.
Mineral wool:
- Creates a thin layer of insulation;
- Holds the temperature well even with a thin layer;
- Absorbs moisture after precipitation;
- The price is higher than for foam plastic.
All these features should be taken into account when you are choosing the paint for the finishing coating of your system. Otherwise, an unsightly facade with shabby paint and repeated investments in repairing the insulation system are waiting for you.
What kind of paint to choose for a warm facade?
The first thing that is important to pay attention to choosing paints is their vapor permeability, the ability of the paint to let air into and out the walls. Often it is called as “breathable” coating. All the façade paints by TRIORA has this property in varying degrees.
Facade paints are divided into groups according to the main constituent substance; differ in strength and duration of coating service. Let’s take a closer look with the example of paints TRIORA.
Acrylic facade paints by TRIORA
- Dilute with water.
- The basis is an acrylic binder.
- Applied at a temperature from + 5 ° C to + 35 ° C.
- Resistant to atmospheric phenomena.
- Can be washed with detergents.
- Coverage serves up to 10 years.
Silicone materials by TRIORA
- Dilute with water.
- The basis is a silicone binder.
- Applied at a temperature from + 5 ° C to + 35 ° C.
- Resistant to atmospheric phenomena.
- Do not absorb dirt and self-cleaning: just wash the facade with hoses and all the contaminants are washed away with water.
- More than 10 years of service.
Solventborne all-weather exterior paint piolite by TRIORA
- The basis is piolite
- They have a unique property to be applied at a temperature of -5 ° C.
- Dilute according to the principle of enamels – with the help of white spirit or solvent.
- Resistant to atmospheric phenomena.
- Do not absorb dirt and self-cleaning: just wash the facade with hoses and all the contaminants are washed away with water.
- 15 years of coverage service.
The most important thing in the material selecting is to take into account the properties of the obtained coating and their compliance with the requirements of the surface the coating is applied on.
How to paint the facade?
How to choose the best option for each material? Focus on how the heater absorbs moisture.
- Foam plastic does not absorb water and does not require active ventilation. It is enough to create coverage, which have resistance to moisture penetration and minimal ventilation. Here you can use acrylic and silicone type of paints.
- Mineral wool absorbs water abundantly; it needs strong ventilation and requires a special coating that ensures minimal penetration of water inside and its free outlet outside. Only silicone paints and all-weather paint piolite by TRIORA can guarantee it.
In the case of using other coatings, moisture will not evaporate freely, will undermine the paint material, and create negative conditions for the insulation.
Important: do not combine materials of different composition during applying. It concerns especially the facades with mineral wool. You create a surface conflict by using acrylic putty and silicone paint or vice versa. A denser material neutralizes the necessary properties of another one.
Why do fronts burn out?
This is the second from the most common mistakes of painting the facades. The cover holds and everything is in order, but the color fades already in the first year after warming. The reason is in incorrect selection of colorants. It is important to use colorants only from the palette for facade paints for paints that are used on the street. Here colorants have a high resistance to ultraviolet and do not burn out in the sun. If the paint has burnt out, then a colorant for interior paints designed only for indoor use were used. Selecting the color of the facade, proceed only from the colors of the special palette.
The facade warming is a time-consuming and expensive process. However, if you follow the entire technology of insulation and choose the most suitable paint, the insulated façade saves the warmth of your home for many years and many resources also.
