How to seal when paving stone
Stone is a kind of decorative material that is often used in the modern room building decoration industry. However, in the process of installing stone, in order to ensure the true natural color of the surface, it is necessary to have certain waterproof measures during the stone installation process. What are the sealing methods? How do different sealing methods work? Today Xiaobian takes you to study together, hoping to help more people understand the stone decoration industry.
The main methods of paving stone sealing are:
1. The air seam is not sealed with sealant, and air convection is formed on the back side of the stone. The water vapor is discharged to the outside to prevent the temperature difference on the stone surface so that the inner surface of the stone does not condense.
2, the semi-seam seal type is to maintain the stand on the stand with no sealant. The façade has a good three-dimensional effect. In fact, the glue layer is hidden inside the joint, but the thickness of the sealant should be about 6mm, but The width cannot be exceeded, and the width should be determined according to the quality of the glue. It should be consistent with the delineation of JGJ120 and JGJ133.
3. Neutral sealing silicone rubber, it is a special glue for stone, sealing all the seams of the facade, the rain of the facade can not enter the back of the stone, so that the stone is in a dry state, except for rain and snow, ensuring The flexural strength and shear strength of the stone are unchanged. It is necessary to ensure that the stone does not freeze, is not alkalized, and ensures the permanentness of the project.
In addition, when sealing stone, there must be a kind of consciousness that although the stone can't breathe like a human, it also needs to be "breathable" to ensure that the bacteria in the stone survive and proliferate. Many measures are carried out around the two points when sealing; therefore, it is recommended that you choose a regular stone paving team to install, to ensure that the stone will have a true natural color in the subsequent use.
