None of the construction is complete without the use of mortar. They are used for foundations device masonry and furnaces, plaster surfaces, as well as in the manufacture of decorating. Widely used solutions for decorative plaster. Its original relief depends not only on the application of tools and techniques, but also by used in its composition components. And whether you will be able to calculate the proportion of the composition for a particular type of solution? Verify their knowledge as possible, analyzing their answers to the assignment of the test.
