Installation and construction
A.Pavement on the wall
1.Clean and level the wall with a spade.
2.Apply the cement on the wall by a brush twice.
3.Fix the slab firmly on the wall by the iron wire and the expansion screw.
4.Pour the cement mortar (1:3)into the gap between the slab and the wall.
5.Remove the mortar and other dirt on the slab surface.
6.Apply and maintain the wet fabric on the slab for 24hours if it is installed at the place under the direct sunshine.
B.Pavement on the floor
1.Mark the horizontal base line on the floor, remove the part above the horiontal base line and fill the part below the base line for the convenience of the construction.
2.Mix and stir the cement mortar with one portion of cement ,four portions of sand proper amount of water evenly to half dried.
3.Apply the cement mortar mixed well evenly on the floor for about 2-4CM thick,put on the Yajiada engineered stone, and adjust it to achieve the desired height.
4.After the adjustment ,take off the engineered stone,apply a thin layer of dry white cement powder on the cement mortar,and wet the cement powder with a brush soaked with water.Should the cement mortar is moist enough to wet the white,cement powder,no water shall apply.
5.Put on the engineered stone, knock it gently with a rubber hammer or a wood hammer to make it nestle closely and completely to the cement mortar,level it and adjust the joints(1.5-3.0)between the neighboring slabs.If there is any slab in the different level with others,take it off,adjust the levelness of the base again,and repeat the steps 4 and 5.
6.Generally,it is necessary to remain a 2mm joint between the engineered stone slabs to evaporate the moisture and offset the expansion stre
ss.For a large-area pavement arrange the expansion joints at the proper distance, to prevent protrusion or crack on the slab due to the expansion/shrinkage on the floor surface or structure.
7.After the pavement of the engineered stone,wait for 3-5days before caulk the joints for the normal drying of the mortar on the base.Caulking too fast may lock too much moisture inside the floor/wall structure and cement sand,and the alkali materials inside the cement will keep on hydration.In such case, the sodium salt and alkali water will come out from the capillaries of the stone with the evaporation of the moisture result in the phenomena commonly called the "alkali flood" and seriously affect the decoration effect.Use the crack filler specially for the stone or the cement for caulking and remove the excessive filler immediately after caulking.
