Cement-based penetrating crystalline waterproof coating
1 Product Introduction
Bolong cement-based penetrating crystalline waterproofing material is an active chemical product imported from abroad, commonly known as masterbatch, with gray color composed of Portland cement, silica sand, etc. The waterproofing principle of powdery inorganic materials is that the unique chemical substances of this material use the inherent chemical properties and porosity of cement concrete itself, using water as a carrier, and transmit with the micropores and capillaries of the concrete through penetration. It can achieve the effect of permanent waterproofing, moisture-proofing and protecting steel bars to enhance the strength of concrete structures.
Two product features
It can withstand strong water pressure for a long time, at least 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 required to be flat and dry like 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
Waterproofing 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. The base surface should be rough and clean. Spray water to wet the base surface. But there should be no open water. Mix the Bolong cement-based penetrating crystalline waterproof coating (water weight ratio) evenly, and use a nylon brush to evenly brush the mixed glue on the waterproof base surface. Generally, apply it twice, and use materials per square meter ( The thickness is.
The interval between coatings should be within hours. When the initial setting of the first coating is still moist, it is better to apply the second coating. If it is too dry, spray water first to moisten it. The mixed glue should be in Use it within minutes. Do not add water when the glue becomes thicker. You can only stir it frequently. The brushing should be even. There should be no white background or deposits on the convex and concave areas.
After the coating is semi-dry, start using mist water Spray maintenance, once a day, for consecutive days to prevent premature drying of the coating.
Commonly used construction methods of coatings include brushing, dry spraying, spraying, etc.
Six precautions
High temperature It is recommended to carry out construction in the morning and evening during open-air construction in weather conditions to prevent premature drying of the coating and affect penetration. When continuing the construction with cement-based materials on the coating surface, it should be carried out after an hour. For example, backfilling with soil should not be backfilled with dry soil within days to prevent it from absorbing water into the coating. . During the 1-hour maintenance period, 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 using a plastic film to protect it to ensure the breathing and ventilation of the coating. .
