First of all, you should carefully clean the material, which will be covered with a mixture of dust and dirt. Sometimes experts even advise priming or polishing the substrate.
Mix the solution should be in accordance with the proportions that are indicated on the instructions for use of the composition. After mixing the components, the resulting mass is applied to the main surface. Most often, the base should be covered with one thin layer using a special spatula.
After applying the mixture on the working surface, you need to fasten the coating with the base. It is important to note that if you are installing the plates, then you definitely need to adjust the elements, as they often shift.To avoid such situations, each part can be simply fixed using special plastic crosses.
