1. Product Introduction
Bolong cement-based penetrating crystalline waterproofing 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. It can achieve the effect of permanent waterproofing, moisture-proofing and protecting steel bars to enhance the strength of concrete structures.
Two product features
Withstand strong water pressure for a long time, at least it can withstand the head of water pressure.
Above the penetration depth.
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 use.
The construction method is simple and the construction cost is low. After the coating is solidified, it is not afraid of collisions 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.
Three product uses
Waterproof construction of concrete structure base, plugging construction of structural cracks and seepage points, waterproofing and plugging construction of underground diaphragm walls, tunnels, bridges, reservoirs, sewage treatment pools in subway stations, and construction of industrial and civil buildings. Waterproofing and sealing of basement bathroom sinks.

Five 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 the water weight ratio of Bolon cement-based penetrating crystalline waterproof coating evenly. Use a nylon brush to evenly brush the mixed glue on the waterproof base surface. Generally, apply two coats. times, the material thickness per square meter is.
The coating 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 glue 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, once a day for several days to prevent premature drying of the coating.
Commonly used coating construction methods include brushing, dry spraying, spraying, etc.
Six Precautions
It is recommended to carry out construction in the morning and evening during open-air construction in hot weather 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 with soil. Do not backfill with dry soil within a few days to prevent it from absorbing water into the coating. During the maintenance period of 1 hour, it is waterproof to 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 to avoid water accumulation, it must be erected when protected by a plastic film to ensure the breathing and ventilation of the coating.
