Stone pavement sealing methods are mainly about three types:
1，An empty seam without sealant, in the back of the stone formation of air convection, the steam exhausted to the outside, to prevent the stone surface temperature difference between the inner surface of the stone will not be thrown condensed water.
2, semi-seam sealed to keep the facade was no sealant stand a very good three-dimensional facade, actually hiding in the internal node layer, but it must ensure that the thickness of the sealant should be 6mm or so, but can not exceed the width, the width shall be calculated decisions based on the quality of plastic. Should be consistent with the relevant provisions JGJ120 and JGJ133.
3, with neutral silicone rubber seal, which is the stone for plastic, the entire facade of the seam sealing, rainwater can not enter the back of the facade of stone, the stone in a dry state secret? Rain, snow, except to ensure that bending strength and shear strength of the same stone. To ensure that the stone does not freeze, not alkaline, and to ensure that the necessary measures permanent works.
In addition, when the seal stone, there must be a sense that although it is not like people breathe stone, but it also needs “breathable”, to ensure that the bacteria survive and multiply stone Reid. When the seal is surrounded by many measures to expand these two points; therefore suggest you’d better choose a regular paving stone installation team to ensure that its subsequent use of stone in the process can have a real lasting natural color.
