Then use a sharp-nosed steel chisel to open a 1 2 cm "V" shaped groove from beginning to end of the crackThe depth of the trough is 1 2 cm, and the dust in the ditch is cleaned (with a pump or air gun). Then the waterproof glue A and B components 1 1 are evenly adjusted and brushed 2-3 times and allowed to dry.
Then use 1 1 cement mortar (according to 5-20% of the cement input, add waterproof glue and fill the groove after mixing thoroughly. Finally, use a steel spatula to scrape the surface flat and make it stickyAllow to dry naturally for 24 hours before soaking in water.
Second, cement mortar repair method. First, 10 cm is cut on both sides of the crack, making it 20 cm wide. Length:
It is 10 cm longer than the ends of the crack, for a total length of 20 cm. Depth: This is the thickness of the mortar layer.
After opening, clean the base surface, there can be no water and no dust. It must be clean and there is no moisture! Then apply 911 polyurethane and brush one piece vigorously on the substrate.
After drying the next day, spread a layer of imitation cloth, and then apply a second layer, which requires that it be evenly painted, and sprinkle sand on top after application. The final step is to repair with cement mortar.
After filling the roof gaps, if you want to strengthen the leakage prevention effect, you can also lay another layer of waterproof membrane, if there is a large area of water leakage or multiple leakage points on the roof, first check whether there are cracks by professionals, and after dealing with the cracks according to the previous plan, the waterproof membrane is laid on the entire roof, if you want to strengthen the waterproof effect, you can also lay the heat insulation board, because the height of the heat insulation board is more than 20 cm, it can achieve the dual effect of protecting the waterproof layer and heat insulation. Families who are reluctant to use heat insulation panels can consider using steel wire mesh concrete (the professional term is steel wire mesh fine stone concrete), and the leak-proof effect is also very good.

Anonymous users2024-02-10What waterproof material is good for roof cracks and leakage: pro Roof cracks and leakage is a good waterproof material with synthetic polymer waterproofing membrane Synthetic high-grade potato waterproofing membrane: with synthetic rubber, synthetic resin or a mixture of the two as the base material, add an appropriate amount of chemical additives and fillers.
Flak-like waterproof material that can be curled through different processes; Or the above-mentioned materials are compounded with synthetic fibers to form two or more layers of flak-like waterproof materials that can be curled. Polymer modified asphalt waterproofing membrane: synthetic polymer modified asphalt is used as the coating layer, fiber fabric or fiber felt is the carcass, and powder, granular, sheet or film material is used as the covering material to make a crimpable accompaniment sheet material.
The roof is the most prone to water leakage, so waterproof must be done well, there are more waterproof materials at present, you can choose according to your own needs, waterproof materials generally to prevent rainwater, groundwater, industrial and civil water supply and drainage, corrosive liquids and moisture in the air, vapor and other materials that invade the building are basically collectively referred to as waterproof materials. The roof is affected by various comprehensive factors, such as mechanics, physics, chemistry, etc., mainly because the roof is directly affected by the atmosphere, freeze-thaw alternation, thermal expansion and contraction, dry and wet changes, as well as some sunlight, ultraviolet rays, ozone, and wind, frost, rain and snow erosion and weathering, as well as some institutional structural influences, temperature difference and hard stretching of the waterproof membrane or coated carcass during construction, so that the waterproof layer is in a state of high stress, which can lead to premature damage to the roof. Therefore, it is necessary to choose good aging resistance, and need to have a certain degree of ductility, high heat resistance materials, you can choose the right waterproof material according to your own needs, if you really want to buy a satisfactory waterproof material also have to ask your friends or professionals, it is recommended to choose a big brand like Soprema, the quality is more guaranteed.
The waterproofing membrane will be different because of different material specifications and different brands. >>>More
1. Tempered glass in the sun room.
Tempered glass is made of ordinary glass that is evenly heated, and when it is close to the softening point, it is uniformly cooled at the corresponding cooling rate according to different thicknesses. The inside of the glass produces strong permanent internal stress, and the tensile stress of the inner layer and the compressive stress of the outer layer are in a stable stress equilibrium state. The original physical properties of the glass are changed, the original performance of the glass is overcome, and the range of use is increased. >>>More
Space-time rifts appear randomly! When there is a rift in space-time, demons can be teleported to the Celestial Realm for a sneak attack.
The cement tile for the roof is still quite good, the reason is that the cement tile is very cost-effective, first of all, the raw materials of the cement tile are generally cement and sand, which is relatively easy to obtain, and the production process is not complicated, naturally compared with other tiles will be a lot cheaper, but although the raw materials are simple, the production process is simple, the cement tiles produced by different manufacturers are not the same, and the characteristics of cement tiles such as waterproof and anti-falling made by large manufacturers are the best, because they have mature production technology, It is an inferior cement tile produced by a small workshop that cannot be compared, if you want to recommend it, I recommend Shengshi Zhuoye's Yinghong cement tile, which is considered a high-quality product in the cement tile.
