What are the advantages and disadvantages of polyurea waterproof coating?
Advantages
- Excellent weather resistance: Can resist extreme climatic conditions such as ultraviolet rays, high-temperature exposure, and freezing for a long time, without aging or cracking, and maintain long-term stable waterproof performance.
- Good chemical resistance: Has strong tolerance to acids, alkalis, salts, and various chemical solvents, suitable for corrosive environments.
- Strong impermeability: Forms a dense, seamless continuous membrane layer, effectively preventing water and other liquids from penetrating, with remarkable waterproof effect.
- Strong adhesion: Has good adhesion to various substrates such as concrete, metal, and wood, and is not prone to detachment or peeling.
- Fast construction speed: After spraying, it can solidify quickly within a few seconds, significantly shortening the construction period and improving efficiency.
- Strong repairability: Local damage can be restored by local repair, without the need for overall redoing, reducing maintenance costs.
- High durability: Long service life, with some products lasting for decades, and no frequent maintenance required.
- Environmentally friendly and safe: Some products can meet food-grade or drinking water safety standards, suitable for places with high hygiene requirements such as water tanks and water boxes.
Disadvantages
- High cost :High prices of raw materials and significant investment in construction equipment result in a higher overall cost compared to traditional waterproofing materials. This may not be suitable for low-budget projects.
- High technical requirements:Requires operation by experienced professionals. Improper control of the spraying process may lead to issues such as bubbles and pinholes.
- Sensitive to environmental conditions :Construction must be carried out in a dry, dust-free, and free of standing water environment. High humidity or dampness of the base layer may affect adhesion and film formation quality.
- Thicker coatings are prone to cracking :When the coating thickness is large, shrinkage cracking may occur in areas with significant temperature variations.
- Possible yellowing :Under long-term high temperature or strong ultraviolet radiation, some products may undergo slight yellowing, affecting the appearance and aesthetics.
- Strict control of ratio and dosage: Both materials A and B must be precisely proportioned. Insufficient dosage may result in incomplete film formation and defects.
Which buildings or projects are suitable for using polyurea waterproof coating?
1. Roof waterproofing of buildings
Polyurea waterproof coating can be directly applied to the surface of buildings, with simple and quick construction operations. No complex construction procedures or equipment are required, and it is suitable for waterproof treatment of various building structures.
2. Basement waterproofing
Polyurea waterproof coating has excellent weather resistance and corrosion resistance, and can be used stably under different climates and environments. For concealed projects such as basements, polyurea waterproof coating can effectively resist the erosion of groundwater and maintain stable waterproof performance.
3. Stairwell waterproofing
When used and constructed correctly, polyurea waterproof coating is generally safe for residents and is suitable for waterproofing projects in building stairwells. Polyurea waterproof coating is usually made of non-toxic materials and does not contain harmful substances. It has no obvious impact on the health of residents during use.
4. Tunnel waterproofing
Polyurea waterproof coating has good chemical resistance and can resist the erosion of common acids, alkalis, and solvents, suitable for waterproofing in special environments such as tunnels.
5. Road waterproofing
Polyurea waterproof coating has good maintenance performance. After construction, it is unlikely to have cracks or detachment problems, and no additional maintenance and repair work is required. Regular cleaning and maintenance can maintain good waterproof performance for a long time, significantly reducing maintenance costs in the future.
6. Landfill waterproofing
Polyurea waterproof coating has excellent weather resistance and durability, able to withstand various harsh environmental conditions such as ultraviolet rays, acids, alkalis, and chemical substances, suitable for environments with harsh conditions such as landfill sites.
7. Toilet and bathroom waterproofing
Polyurea waterproof coating has good chemical resistance and can resist the erosion of common acids, alkalis, and solvents, suitable for waterproofing in damp environments such as bathrooms.
How much more expensive is polyurea waterproof coating compared to ordinary coatings?
The price comparison between polyurea waterproof coating and ordinary waterproof coating shows that polyurea waterproof coating has a greater advantage in terms of price.
- The price of polyurea waterproof coating is relatively lower. Compared with traditional waterproof materials such as waterproof sheets and wet-laid waterproofing, the price of polyurea waterproof coating is more economical and practical. Its manufacturing cost is relatively lower, and it can be constructed quickly, reducing labor and time costs.
- The construction cost of polyurea waterproof coating is lower. Polyurea waterproof coating can be directly applied to the surface of buildings without the need for complex processing and construction like traditional waterproof sheets, reducing procedures and construction difficulty. Its construction speed is fast, and the requirements for construction personnel are relatively low, reducing construction labor costs.
- After the polyurea waterproof coating is constructed, no additional maintenance and repair are required, reducing the later maintenance cost.
