Apr 19, 2021
1, Regarding the stone alkaline, you need to prepare before its construction, the first consideration should be given on the design of alkaline to eliminate, as far as possible to design it into dry hanging in the form of installation, and to consider its waterproof and structure for the bibulous rate of stone and its physical properties are all need to conform to the use of the installation area.
2, Stone before the installation can be on the back of the stone or side part of the daub some special anti-alkaline treatment agent, the solvent will generally directly infiltrate into the capillary stone, so that water and salt and other substances and other dust substances can not invade, so as to cut off the pan alkaline.In the process of installation, the adhesive property between the stone and the wall is not affected by the back coating treatment.In addition to these, also need to be at the bottom of the stone plate beseared with a layer of resin glue, and then paste a layer of chemical fiber silk mesh cloth on the resin glue, thus forming a certain tensile waterproof layer.
3, In the cement mortar used in the inset into the appropriate water reducing agent, in order to reduce carbon dioxide compound material precipitation, for paste the mortar required its consistency should be in 6-8cm.In the outdoor shop paste stone, you can use some adhesives, which can effectively preserve the water molecules in the stone, in order to prevent cement mortar after condensation of the stone in the water molecules secreted.
4, Before the stone shop and paste, must not be on the wall water operation, in the ground at the root of the wall should be set up due moisture-proof layer, stone in the toilet and other areas, the basic part should do a good job of anti-infiltration treatment.
5, The stone decoration on the outer wall, in order to prevent the water from entering the stone from the stone plate seam, so that the late installation should be left a certain distance from the wall seam, the width of the gap should not be less than 5mm, finally need to use the stone special silicon adit weather sealant to seal it.
