Analysis of the importance of epoxy floor waterproof layer: before the construction of epoxy floor paint, we must know whether the ground has done waterproof layer, if not do waterproof layer, we must first do a good waterproof layer, so as to eliminate as far as possible the project may appear quality problems, to ensure the quality of the project. The waterproof layer has an important influence on the service life of epoxy floor paint, especially on the underground and first floor epoxy floor system. If the waterproof layer is not ready, the later stage floor paint system is very simple, showing bubbles and delamination. 首先在施工防水层前，需求先将基面处理好，确保其含水率控制在4%以下。假如地上太湿润，则可以用用鼓风面鼓风或许用太阳灯照耀基面，一般底层枯燥时刻要求28天以上。接下来就需求施工重要的防水层了。一般情况有以下两种。
First of all, before the construction of waterproof layer, the demand is first disposed of the base surface to ensure that its moisture content is controlled below 4%. If the ground is too wet, you can use the blast surface blast or sunlight to shine on the base, generally the bottom of the dry time requires more than 28 days. Next, we need to build an important waterproof layer. Generally speaking, there are two kinds.
1 laying fine sand and thin film
Plastic film is laid on the ground after backfilling. First, a layer of fine sand is laid on the surface of the backfill, then waterproof felt and plastic film are laid, and finally concrete layer is poured. There should be at least 10CM stacking on the lap of two plastic films.
2 coating waterproof coating
First, the epoxy floor paint is applied on the cement floor to form a waterproof isolation layer, then a cement mortar protective layer is applied, and finally the epoxy floor paint is applied on the cement mortar protective layer. Waterproof coating is a kind of viscous liquid which is painted on the surface of a building and formed by the evaporation of solvent or water or the chemical reaction of two components, so that the building surface is separated from water and then waterproof and sealed.
Metal-type wear-resistant floor is composed of selected aggregates, high strength cement, special admixtures, pigments and polymers with definite size gradation. Dry-type spreading method is selected to evenly distribute the surface of concrete at the initial setting stage. Construction with construction materials can form a layer of extremely fine and high strength color resistance on the bottom concrete. Grinding the surface layer.
Non-metallic wear-resistant floor is composed of selected aggregates, high strength cement, special admixtures, pigments and polymers with definite size gradation. Dry-type spreading method is selected to evenly distribute the appearance of concrete at the initial solidification stage, and a fine color wear-resistant surface can be formed on the concrete at the bottom of the floor by using professional construction materials. Layer.
There are four colors (cement, gray, red and green) of wear-resistant hardener. The advantages of the hardener are good bonding with the concrete at the base, fine appearance, high wear resistance and strong impact resistance. It can be widely used in concrete exterior, such as production and processing workshop, machine maintenance workshop, warehouse and so on. Its defect is not suitable for long-term wet environment on the ground, often touching acid, crystalline salt and other chemical solvents on the ground. According to the requirements of ground wear-resisting layer (1.5 - 3.5mm), the recommended dosage is 5 - 12kg.
Non-metallic wear-resistant floor is composed of selected aggregates, high strength cement, special admixtures, pigments and polymers with definite size gradation. Dry-type spreading method is selected to evenly distribute the appearance of concrete at the initial solidification stage. Construction with professional construction materials can form a fine layer of colorful and colorful resistance on the concrete at the base. Grinding the surface layer.
