The choice of thin-coat render is a solution for years. A well-chosen one will effectively protect the external wall insulation and emphasize its mass. So instead of suggesting the modern renders’ price, take a good look at your needs.
What requirements must a good render meet?
The house rendering provides an aesthetic appearance for the building, and although it should remain in perfect condition for many years, unfortunately, it is exposed to many threats. These include, among others:
- dust,
- dirt or soot,
- algae and fungi.
Buildings next to the road are naturally more strongly exposed to pollution from the street and exhaust fumes.
In addition, the thin coat renders work in harmful weather conditions, such as rain and wind. It also happens that the building turns green over time because of algae and fungi growth. All these factors gradually lead to the degradation of the external walls and can lead to the erosion of the deeper layers of thermal insulation.
Which render is best for house?
Mineral render
Mineral renders boast high strength and are vapor-permeable. After painting with silicone paint, these renders are also very resistant to contamination. They are therefore suited to homes located directly on a busy road.
Acrylic renders
Acrylic render provides high water-repellent and resistance to microbial contamination. For this reason, these modern house rendering systems are ideal for houses near green spaces.
Silicone renders
Silicone render is a very durable and self-cleaning render. Such house render boasts resistance to adverse weather conditions, microbiological contamination, and dirt. Among silicone rendering properties are hydrophobicity, and vapor permeability, so they retain their original color for years.
Silicate-silicone renders
Silicate-silicone render has selected advantages of silicone render but is available at a lower price, so does cement render. Such an external render offers high resistance to changing weather conditions, biological corrosion, and dirt while being vapor-permeable, self-cleaning, and not very absorbent.
Did you choose a rendering system? Let’s get to work!
Regardless of the chosen thin coat render, we should remember a few rules. Otherwise, even the best and most expensive materials can lose their properties. Here’s what you need to take care of:
- House renders, like any paint or varnish, need an even surface. For unprimed render, always apply a coat of primer before rendering.
- Apply a render in spring or autumn at a temperature of about 15-20°C. Hold off on rendering half a year after erecting structural walls. Then your external wall will not crack.
- Apply the modern or conventional render at the right time. It must not be too wet, or streaks will appear on it.e
- When you texture, your render must not be too dry. Otherwise, the work becomes more difficult because of the need to press the trowel harder, and scratches may appear on the render.
The choice of modern render, contrary to appearances, is not difficult, but it requires careful analysis. Before you plan to purchase, you should consider the insulation material you have. Think about your needs and environmental conditions, as this layer should last a long time.
