If the surface of the substrate is contaminated with moisture, dust, stains, etc., it will seriously affect the adhesion of the sealant to the substrate, resulting in failure of the sealant. Therefore, the surface of the substrate must be cleaned with a suitable solvent or cleaning agent before applying the sealant. During the construction, the nozzle is cut into an appropriate size so that the nozzle can extend into the seam 1/2. The injection should be slow and even, so that the glue fills the joint without leaving a gap, and the proper pressure is required to make the glue fully contact the surface of the substrate. When applying the glue, the ambient temperature should be between 5-40 °C, the relative humidity should be between 40%-80%, too dry or too humid weather, the temperature is too low or too high, it is not suitable for sizing, the surface is directly exposed to sunlight or It is not suitable for the surface temperature of the substrate to exceed 50 °C. After the glue is applied, the glue cannot be rained before it has been cured, and it cannot withstand the load and displacement.
