In many applications, acrylic paint meets almost all requirements. In contrast, acrylic is the optimum color for concrete. Why acrylic paint is so well suited for concrete, what you should pay attention to and instructions for painting acrylic paint on concrete are given below.
Acrylic paint, the versatile color
Although acrylic paint was developed as early as the 1930s and has been marketed since the 1940s, it did not become widely accepted until the late 20th century. Acrylic paints and varnishes are now available for every imaginable application:
- as children's paints
- for various materials such as glass, wood, metal, plastics
- indoors and outdoors
- as a glaze, as a conventional layer of paint, for filling a viscous mass
- for artists ( from the canvas painter to the bodypainter)
Quality and properties of acrylic paints
The versatility is enormous. However, the use of acrylic paint will depend especially on the quality and characteristics of the particular product. However, high quality and controlled properties lead to a relatively high price for acrylic paint. The essential point why acrylic paints were able to assert itself is its sustainable use.
Acrylic paint is mechanically not very resistant
The toxicity of acrylic paint over other paints and varnishes also allows the use as a child's paint. In the automotive industry, it is the decisive reason compared to the previously used synthetic resin paints.
However, there is a particular drawback everywhere: Acrylic paints are not particularly resistant mechanically. Therefore, stressed surfaces must be sealed with a protective clear coat of synthetic resin paint.
For concrete, acrylic paint is better than any other product
In the case of concrete, however, acrylic paint has all the advantages. In addition there are properties that are particularly well suited to concrete. For example, acrylic paint is diluted with water. After curing and drying, however, the acrylic paint is impermeable to water and can no longer be softened or removed with water.
The advantages of acrylic paint on concrete
This coating means weather resistance, water can no longer reach the concrete. As a result, contact with air carbon dioxide can no longer occur and carbonation is prevented. As a water-diluted paint, the acrylic paint penetrates efficiently into the pores of the concrete and seals it. Thus, the concrete is extremely well protected against weathering. Acrylic paint protects the concrete and ensures a long service life. Acryl Acrylic paint should not be used on every wall
In addition, acrylic colors are particularly convincing due to their special color depth and color brilliance. Whether the sun is shining or the façade of concrete is wet with rain, the acrylic paint is always colorfast. However, due to the above properties, acrylic paint may not be used everywhere. Where a wall or wall must be permeable, ie vapor-permeable, it is strongly advised against using acrylic paint.
Step-by-step instructions for painting acrylic paint for concrete
- Tools such as rollers and brushes
- Ladder or scaffolding
- 1. Preparation
Like any other wall or facade, the concrete must first be prepared. Moss and other residues are to be removed cleanly. A steam jet is particularly suitable for this. Damage must be repaired.
In addition, the now wet concrete wall or facade must dry completely. If it rains, it must not have rained for at least 5 to 10 hours before painting. Even after painting the acrylic paint on the concrete, it should not rain for at least 5 to 10 hours, so that the paint has enough time to dry out.
2. Prepare the acrylic paint
The acrylic paint is now diluted with water and stirred well. Most manufacturers recommend a dilution of around 10 percent, but up to 20 percent can be quite common. St 3. Painting the concrete
Now the concrete is painted like every facade. To cover the color, at least two operations are required. The paint is stroked in the cloister, as first across and then from top to bottom or vice versa.
4. After drying
The façade is now efficiently protected against weathering. Dirt can easily be washed off, as the paint is impervious to water.
