1. Product Introduction Bolong R cement-based permeable crystalline waterproof material is an active chemical product imported from abroad, commonly known as masterbatch, with gray powdery inorganic materials composed of Portland cement, silica sand, etc. Its waterproofing principle is: This The unique chemical substances of the material make use of the inherent chemical properties and porosity of cement concrete itself, using water as a carrier, and through penetration, are transmitted to the micropores and capillaries of the concrete. c achieves the effect of permanent waterproofing, moisture-proofing and protecting steel bars to enhance the strength of concrete structures.
2. Product Features
. It can withstand strong water pressure for a long time and can withstand at least .
, penetration depth C or above.
, self-healing ability. There is a unique catalytic effect that activates to produce new crystals when exposed to water. Therefore, when water penetrates into tiny cracks in the concrete structure after a few years, new crystals will be produced to block the water. This self-healing ability is unique.
, enhance the strength of concrete, resist chemical corrosion, and protect steel bars.
, non-toxic, pollution-free, safe and environmentally friendly, and can be used in domestic water concrete structures.
. The construction base surface is not as smooth and dry as the general waterproof layer. On the contrary, the base surface is required to be rough and wet for better results.
. The construction method is simple and the construction cost is low. After the coating is solidified, it is not afraid of collision and is resistant to puncture and tearing. Therefore, adding filling soil to install steel bars does not require a protective layer, reducing the project cost.
, the surface can be coated with cement mortar, lime paste, epoxy resin and other coatings, and the bonding effect is good.
3. Product use
Waterproofing construction of concrete structure base, blocking construction of structural cracks, seepage points and holes, waterproofing and plugging of subway stations, underground diaphragm walls, tunnels, bridges, reservoirs and sewage treatment pools Leak construction, waterproofing and plugging of basements, bathrooms and pools in industrial and civil buildings.

5. Construction points
Clean the base surface, which should be rough and clean. Spray water to wet the base surface, but there should be no open water. Mix Bolon cement-based penetrating crystalline waterproof coating: water:.. (weight ratio) evenly, and use a nylon brush to evenly brush the mixed rubber on the waterproof base surface. Generally, paint twice, using material per square meter (thickness: .).
The painting interval should be within hours. When the initial setting of the first coat is still moist, it is better to apply the second coat. If it is too dry, spray water to moisten it first. The mixed rubber should be used within minutes. When the rubber becomes thicker, no water can be added. It can only be stirred frequently. The paint should be evenly applied, and there should be no white background or sedimentation on the convex and concave areas.
After the coating is semi-dry, start spraying with mist water for maintenance, three times a day, for several consecutive days, to prevent the coating from drying out prematurely.
Commonly used construction methods for coatings include: brushing, dry spraying, spraying, etc.
6. Precautions
For open-air construction in hot weather, it is recommended to carry out construction in the morning and evening to prevent the coating from drying out prematurely and affecting penetration. When continuing the construction with cement-based materials on the coating surface, it should be carried out after an hour, such as backfilling soil. , do not backfill with dry soil within days to prevent it from absorbing water into the coating. During the maintenance period of 1 hour, it is waterproof from rain, frost, exposure to the sun and low temperatures below 10 degrees Celsius. It is better to cover it with a moisture bag for open-air construction, but avoid water accumulation. When using a plastic film to protect it, it must be set up to ensure the breathing and ventilation of the coating. .
