What are the ways to identify the quality of balcony waterproofing materials

One look at the elasticity, the better the elasticity, the better the quality, the second look at the dispersion force, a good coating is very lubricated, stirring is not difficult, and the third look at the color, such as the waterproof coating is dark black after adding cement, the surface is smooth and smooth, etc.

Because many consumers are not professionally engaged in building materials-related work, some identification of the composition of the material itself will not be talked about here. First of all, when you buy a product, you must first consider the popularity of the product, word of mouth, etc., because relatively speaking, the products of large companies are more trustworthy than those of small workshops, and secondly, "three points of materials, seven points of construction", so it is not only necessary to choose good waterproof materials, but also to carry out standardized construction in accordance with the requirements. Finally, although waterproofing is a hidden project in decoration, its importance is unquestionable.

Look at the thickness, look at the tensile force, look at the flexibility, etc. Balcony waterproofing is generally JS cement-based waterproof coating, and polyurethane waterproof coating. The quality of the waterproof material of the project is average, because the price is too low.

In order to ensure the quality, buy waterproof materials from the manufacturer, (the quality of the building materials city is generally not very good, the weight is not enough), a bucket is enough, and you can brush the original waterproof layer two to three times, and wait for it to dry, and do a closed water test for 24 hours.
