Do You Know The Diffences between Different Kinds of Waterproof Coating Materials?

First, rigid waterproof material construction

The construction of rigid waterproof materials mainly refers to the construction of waterproof mortar or waterproof concrete.

Rigid waterproof material refers to the use of cement, sand and stone aggregate as raw materials, or a small amount of admixtures, polymers and other materials, 

through reasonable adjustment of the mix of cement mortar and concrete, reduce or inhibit the porosity, improve the pore structure characteristics,

 It is a waterproof material of cement mortar and concrete with certain impermeability prepared by increasing the compactness between the interfaces of various materials.

Second, coating waterproof material construction

Waterproof coating (also known as coated waterproof material) is a fluid or semi-fluid substance, painted on the surface of the base, through the solvent or water volatilization, 

or the chemical reaction between the components, the formation of a certain elastic film, so that the surface is isolated from water, waterproof, moisture-proof effect.

The development and application of waterproof coatings in China began in the 1960s, initially mainly asphalt based waterproof coatings, the past decade has been from

 the traditional asphalt based waterproof coatings to polymer modified asphalt waterproof coatings and synthetic polymer waterproof coatings development,

 has developed and produced a low, medium and high-grade series of products, rich output and variety, to promote the development of building waterproof engineering.

Coating waterproof construction is divided into thin coating construction and thick coating construction according to film thickness. Thin coatings are often applied

 by brushing or spraying. Thick coatings are often applied by rubbing or scraping. Due to the different properties of the coating itself, the tools and processes used are also different.

 According to the needs of the project, the coating waterproof can be made into a simple coating layer or a matrix reinforced material coating (plus glass fiber cloth or chemical fiber,

 polyester fiber felt) into a cloth two coating, two cloth three coating, multi-cloth multi-coating.

Three, waterproof coil construction

Waterproof coil is an important kind of building waterproof material. Generally, it can be divided into three categories: asphalt waterproofing coil with asphalt as the basic raw material, 

polymer modified asphalt waterproofing coil with polymer modified asphalt as the basic raw material and synthetic polymer waterproofing coil with synthetic polymer material as the basic

 raw material. The former is the traditional waterproof coil, but its body material has been new development and application, in China's waterproof engineering still has a certain use;

 The latter two types of waterproof coil represents the development direction of waterproof coil, because of its superior performance, it is a new type of waterproof coil vigorously developed

 and applied in our country in the future.
