Chalk boards can be found in stores quite often. But such a board is easy to make on your own, while departing from the usual black and green fields.
It is necessary
- - a frame with a solid back or any other solid surface;
- - acrylic paint;
- - flat brush;
- - tile grout.
Instructions
Step 1
Some companies have special compounds for covering school boards, but in practice it is a great luck to find them on sale. They are used most often to mask scratches, and therefore are sold in small volumes, and the price is disproportionately high. Therefore, it is preferable to purchase a ready-made board or make a covering for it yourself. You can find recipes in which enamels and construction cement are mixed. Such a coating turns out to be very rough, you have to wait a very long time for drying, and an unpleasant smell excludes the use of the composition in the apartment. Acrylic practically does not smell and dries very quickly, therefore it is recommended to use it, and as an additional element to take not cement, but gypsum or grout for tiles based on it.
Step 2
Almost any material is suitable for making a board: thick cardboard, plywood, boards, even laminate or some types of plastic. When choosing a material, it should be remembered that paint adheres very poorly to surfaces such as plastic, metal or plexiglass. If possible, you should choose another material, and if it is nevertheless decided to use plexiglass, metal or plastic, the surface is sanded and covered with a primer, only after that you can apply the composition for making a chalk board.
Step 3
When working, you should take care of safety precautions, namely, work only in a well-ventilated area. When acrylic is combined with grout, an unpleasant odor often appears. The mixture dries very quickly, therefore, before starting painting, you need to protect all surfaces that the paint can get on, and use the whole diluted mixture at once. The grout should be at least 1/5 of the amount of paint; it is better to pick it up in color as close as possible to the planned shade of the chalk board. If you take white gypsum, the color will end up not so saturated, instead of black it may turn out to be gray. Stir the mixture quickly and thoroughly to form as few lumps as possible.
Step 4
When painting, most often one layer is not enough, it is better to paint in 2-3 layers so that the surface does not shine through the paint. The grains of the mixture are removed before the board is dry. To ensure even coverage, alternate layers with vertical and horizontal strokes, letting the previous layer dry before applying the next. When the last layer is completed and dry, the board is carefully rubbed with chalk and wiped with a hard dry cloth, sanding. Whenever possible, use soft chalk for drawing so as not to scratch the surface. The chalk can be washed with a dry cloth or sponge, and occasionally a damp cloth can be used to clean the field.
