Acrylic paint was first used in 1950, this paint dissolves in water and alcohol. Those acrylic paints that are water-soluble can create a thick or thin surface depending on the amount of water you add to the paint, and after drying, they look like oil paints or watercolors. Acrylic paints are very popular today because of their high flexibility and quick drying after use
One of the most popular types of paint for facades is acrylic paint. Acrylic paint has high flexibility, so it can be used on almost any smooth surface.
To use acrylic paint, the surface must be smooth and even, and it is also recommended to use a primer before applying the paint.

How To Apply Acrylic paint To The Wall

The best paint to use in wall paintings is acrylic. To paint underneath, you can use latex paint (also known as interior house paint) which will save you some money, as latex paint is cheaper and has better coverage than quality acrylics. For detailed work, you should use high-quality acrylics, such as soft acrylics, which are a good choice for painting on brick. This advantage of not producing odor in acrylic paint makes it an ideal paint for use in the entire interior of the house.
For external walls you should use masonry paint. It comes in a variety of colors and finishes and is designed to protect your walls from weather damage. Whether you choose a neutral color or a bolder color, masonry paint is the right coating for the job. Water-based acrylic paint is usually the best paint to use on exterior walls. This paint is great for waterproofing your walls, but at the same time it evaporates the moisture inside the wall, which prevents dampness.
How to prepare the wall before mural painting
Before you start painting, you should check the wall and prepare your work space. Clean the wall.
First, make sure the wall is clean and free of moisture or structural problems, such as cracks. If you see any cracks, repair them thoroughly and be aware that there may be an underlying structural issue that could eventually cause cracks in your mural. Inspect the wall closely for signs of mold, dirt, wax, oil, or grease. If you find one, give it a thorough clean and be aware that mold may return unless the root cause is corrected. Even if the wall looks clean, it’s a good idea to wash it anyway with a mild soapy solution like trisodium phosphate to make sure the job is completely clean.
Wall preparation
Plastering the wall is an important step in creating a mural, as the primer helps the paint stick to the wall easily.
In some cases, you can apply the primer directly over the paint that is already on the wall and the mural will be fine. It depends on how much of the surface you want to work on and how long you want the mural to last. If you are really concerned about the longevity of your mural, there are other preliminary steps you should take before you begin painting.
To have the longest lasting and best adhesion of acrylic paints to the wall, remove the existing paint from the wall by sanding with a sanding block. To reduce dust from dry sanding, prepare a solution of mild soap mixed with trisodium phosphate or dishwashing liquid with a bucket of water. Dip the sanding block into the bucket of cleaning solution, squeeze out the excess water and sand the wall thoroughly and allow the wall to dry.
After the wall is completely dry, apply a layer of acrylic primer on the entire wall.
Now, you have three options
• You can paint directly on the wall with acrylic paint. This is what most people want to do at this point. If you are ready to paint, go to the next section.
• You can add texture to the wall (for example, using plaster). It can make for an interesting surface, but be aware of how it affects the final painting.
• If you prefer to paint on canvas, you can attach a large piece of pre-prepared unstretched canvas to the wall using glue or wallpaper paste. However, don’t try to stick a finished painting onto an unstretched canvas, as it is very difficult to stick properly.
