If you do not correctly prepare the surface of the wall, the paint may not cling to the wall, and even if it does, you will probably not obtain the look or durability that you wish. If you do properly prepare the wall’s surface, the paint may attach to the wall. As a result, preparedness is very necessary.
To get started, you will need a wall that is clear of debris such as dust, mildew, mould, grease, oil, and damage such as holes, cracks, or wetness. Even if the wall doesn’t seem to have any dirt on it, you should still make sure to clean and dry it properly. If there are any structural problems, you should use spackle to seal and smooth the surface. After you have ensured that the surface is clean and even, the next step is to apply primer. This step is essential because it increases the likelihood that the paint will adhere to the wall.
It is acceptable practise in many circumstances for some individuals to apply their primer straight on the layer of paint that is already there. Sanding the surface and stripping it of its paint is something that has to be done if you want to achieve the highest possible level of quality and durability. To reduce the amount of dust produced by dry sanding, dip a sanding block into a solution of mild soap that has been dissolved in a pail of water. After that, remove any excess moisture with paper towels, and start sanding the wall. After the wall has been let to dry for an adequate amount of time, you may go on to applying a layer of acrylic primer.
Your decision over what to do next is completely up to you. This is the point at which the majority of people will start painting the mural. Plaster, on the other hand, may be used to create a more textured surface that can be painted on by certain individuals. If you go ahead and choose to use this strategy, you must ensure that the final mural will not suffer as a result. On the other hand, some individuals like painting directly onto canvas. You may implement this alternative by applying a strong adhesive, such as wallpaper paste, to the wall and affixing a piece of pre-primed, unstretched canvas in the dimensions of your choosing. If you want to avoid damaging the end product or having trouble mounting the artwork, you should glue the canvas to the wall before you begin painting your mural. This will prevent you from having either of those problems.
