The thickness of a cementitious permeable crystalline waterproofing coating depends on a number of factors, including the specific application, the type of coating and the manufacturer's recommendations, the application method, and the expected waterproofing effect.
Generally speaking, the application thickness of this type of paint is usually 10 mm to 20 mm, sometimes thicker may be required, especially for thicker cement substrates, multi-layer construction may be required to achieve the desired waterproofing effect. The interval between the application of each layer is usually determined by the drying time of the paint, which should be recommended in the paint product sheet.
Before construction, the product manual and construction guide provided by the manufacturer should be read and understood in detail to ensure that the construction is carried out in accordance with the recommended construction methods and requirements to give full play to its waterproof performance. In addition, considering different environmental conditions and the absorbency of the substrate, it may be necessary to adjust the thickness to ensure the effectiveness and durability of the waterproofing layer.
In practical application, in order to ensure the waterproofing effect, it is recommended to consult a professional waterproofing engineer or construction team to obtain the most suitable advice and construction plan for the specific project.
