Caberry Water-based Environmental Polyurethane Waterproof Coating 

I. Product Overview

II. Core Features

1. Ultra Eco-friendly, Meets International Standards

   • Solvent-free water-based formula, third-party tested VOC content is only 5g/L, far lower than China national standard ≤120g/L and EU REACH requirements
   • No pungent odor after opening, no residue after construction, can be directly used in potable water tanks, swimming pools and other places that contact with human body
   • Non-flammable, safe for transportation and construction, no fire risk
   
   

2. Super High Elasticity, Strong Crack Resistance

   • Elongation at break up to 800%, can deform synchronously with the thermal expansion, contraction, settlement and vibration of the building base
   • Automatically cover and repair fine cracks of the base layer ≤3mm, effectively prevent leakage recurrence
   • Tensile strength ≥1.8MPa, 3 times higher than the national standard requirement, strong tear resistance
   
   

3. Strong Adhesion, No Peeling or Channeling Water

   
   
   • Firmly bond to concrete, cement mortar, stone, wood, metal and other substrates, adhesion strength ≥1.5MPa
   • The active ingredients in the product can penetrate into the capillary pores and micro-cracks of the base, integrate with the base to form a crystal dense waterproof layer
   • Seamless coating, completely solve the problem of easy leakage and water channeling at the lap of traditional coils
   
   

4. Excellent Weather Resistance, Long Service Life

   
   
   • Wide temperature resistance: -30℃~160℃, no brittleness at low temperature, no flowing at high temperature
   • Passed 720 hours UV and artificial climate accelerated aging test, outdoor exposed service life up to 20+ years
   • Water, acid, alkali and mildew resistant, performance does not decrease after long-term immersion in water
   
   

5. Easy Construction, High Efficiency

   
   
   • One-component design, ready to use right after opening, no on-site mixing, avoid human error
   • Support multiple construction methods: brush, roll, spray, easy to operate
   • Fast drying: surface dry time ≤2 hours, hard dry time ≤8 hours, effectively shorten the construction cycle

III.Application Scenarios

Ⅳ.Technical Specifications

Ⅴ.Application Method

1. Base Preparation

• The base must be solid, flat, clean, no dust, no oil, no cracks
• Internal and external corners should be made into arc shape (R≥50mm) for uniform coating
• If the crack width >0.3mm, repair it with epoxy mortar or leak plugging agent first
• Base moisture content should be ≤10% (test by plastic film method: no condensation after 24h coverage)

2. Construction Process

• Primer Coat: Dilute the coating with 30% clean water, brush the base evenly to form a sealing layer, enhance adhesion
• First Coat: After the primer is surface dry (about 2-4h), use a rubber scraper or brush to apply evenly in vertical direction, thickness control 0.5-0.7mm
• Reinforcement Layer: For weak parts such as pipe root, floor drain, internal/external corners, deformation joints, use "one fabric, two coats" process: first apply a layer of coating → lay 300mm wide non-woven fabric (lap width 100mm) → apply another layer of coating to completely cover the fabric
• Second Coat: After the first coat is touch dry (about 8-12h), cross apply in horizontal direction, thickness control 0.5-0.7mm
• Third Coat: According to design requirements, you can apply the third coat, total thickness reach 1.5-2mm
• Protective Layer: After the coating is completely dry (about 24h), you can carry out follow-up processes such as cement mortar or tile laying

3. Reference Consumption

• 1.0mm thick coating: about 1.2-1.5kg/㎡
• 1.5mm thick coating: about 1.8-2.2kg/㎡
• 2.0mm thick coating: about 2.4-2.8kg/㎡

4. Construction Notes

• Construction environment temperature: 5℃-35℃, relative humidity <85%
• No construction in rainy, snowy or windy days
• Mixed coating should be used up within 2 hours to avoid curing waste
• Keep ventilation during construction, workers should wear gloves and masks
• Before the coating is completely dry, no trampling or heavy stacking

Ⅵ.Packaging & Storage
