Granite stone is a building material used in construction. Because granite stone has the characteristics of natural stone and contains certain iron elements, it is easy to produce chemical reaction when it encounters humid environment, which affects the service life of granite stone. Therefore, it is necessary to do a good job of sealing when installing granite stone. There are many kinds of granite stone sealing methods, each with its own characteristics, and when using the seal, it is necessary to decide which product and solution to use according to the actual environment and the type and characteristics of the stone.
First, the granite stone seal is sealed in a way that does not add sealant. Air convection is formed on the back side of the granite stone, and the water vapor is discharged outside, preventing the temperature difference on the surface of the granite stone so that the inner surface of the stone does not condense water. If it involves the method and direction of rainwater discharge, the design institute should fully consider in advance the design. The rainwater or condensed water flow should be discharged from the wall behind the stone. It can also be two or three layers, preferably each layer. There is a ram to drain the rain.
Second, the granite stone seal is sealed with a neutral sealant. It seals the seams of the granite stone facade so that the rainwater on the facade cannot enter the back of the stone, which can make the stone densely dry (except for rain and snow), thus ensuring the bending strength and resistance of the granite stone. The shear strength does not change. To ensure that Laizhou stone does not freeze, not alkalized, and to ensure the permanent nature of the project.
Third, the sealing of the granite stone is sealed by a semi-seam seal method. Keep the granite stone façade in a position without sealant, so that the façade has a good three-dimensional effect. In fact, the rubber layer is hidden inside the joint, but the thickness of the sealant should be about six millimeters, and should not exceed The width, the width should be determined according to the quality of the glue.
