Australian sandstone is formed by the weathering, water erosion, and sedimentation of quartzite over billions of years. Due to Australia's stable geological blocks and unique natural environment, the quality, noble colors, and distinctive textures of Australian sandstone have been created, making it a decorative stone. Australian sandstone belongs to the natural sandstone category, with a specific gravity of 18KG/M3, and is generally used for exterior decoration. Australian sandstone has a deep yellow color and small pores. When used in buildings, it can display a solemn and rustic landscape. This type of stone has fine and obvious patterns, and attention should be paid to the texture direction. Generally, it can only be used for dry hanging, and due to its loose structure and light weight, the thickness of the dry hanging board is generally controlled at 3mm or more to ensure installation safety.
4. The amount of water added is 16% to 18% of the weight of the repair material, which is 8-9 kilograms of water per bag of material
Construction method:
1. Before use, it is necessary to clean the loose materials and dust on the surface of the repaired concrete, and only when there is no visible water can construction be carried out.
2. When mixing, the repair material should be mixed evenly according to the water consumption provided in the instructions (i.e. 8-9 kilograms of water per bag) before pouring for construction. If the pouring area and volume are too large, a small amount of fine stones or large sand can be added to reduce concentrated exothermic reactions. Pour the mixed slurry into the area that needs to be repaired, compact and smooth it, and cover it with plastic film and water it for curing in a timely manner after the repair slurry has finally set. In winter, it is necessary to cover it with cotton felt for insulation protection.

Cracks caused by defects in the insulation layer: Cracks caused by deformation and shrinkage of board joints. Identify the area where the crack in the board seam is greater than 1 millimeter and perform local repairs on the aforementioned cracks. Specific method: Cut a groove along the crack of the board to the cement mortar base, with a width of about 1.2 centimeters. Clean the groove thoroughly and remove the surface protective layer of the mesh cloth or loose animal dust along both sides of the groove by 5 centimeters. Inject about 1/2 of the on-site foamed hard polyurethane into the groove, repair and level it after foaming, or embed a 1.4-fold polystyrene board round rod in the groove. Insert the Tianbu brand TB-998 sealant into the uneven groove until it is flat. Scrape one layer of Tianbu brand TB-999 crack resistant and water-resistant adhesive along the groove, and then embed the crack resistant reinforcement cloth. The overlap with the seam side should not be less than 4 centimeters. Scrape another layer of Tianbu brand TB-999 to cover the crack resistant reinforcement cloth, forming a composite coating with high tensile strength and flexibility.
3. Road opening hours: Depending on the customer's design intensity and construction season, the fast opening hours are 2-8 hours.
Attention: This product is packaged in 50kg/bag (kraft paper composite bag)
Storage conditions: Dry environment for 12 months without affecting use

When the outdoor temperature is lower than the indoor temperature, the contraction rate of the exterior wall is faster than that of the internal insulation system. When it is higher than the indoor temperature, the expansion rate of the exterior wall will be higher than that of the internal insulation system. This repeated deformation keeps the internal insulation system on an unstable wall foundation. According to data and actual measurements, a concrete wall with a spacing of 6m undergoes a deformation of approximately 4.8mm under the condition of an annual temperature difference of 8 ℃. This repeated deformation stress not only makes the exterior wall susceptible to damage from temperature difference stress, but also easily causes hollowing and cracking of the internal insulation system. Another obvious drawback of internal insulation is that the presence of structural cold (hot) bridges can easily cause excessive local temperature differences, leading to condensation. The immersion or freeze-thaw of condensation water can easily cause mold and cracking on the insulation walls.
