CUALI® Hollow Repair Adhesive: The Professional Fix for Tile Hollowing Issues

Tile hollowing is a frustrating and common problem—loose tiles rattle, crack easily, and pose safety hazards over time. Traditional repairs involve costly tile removal and replacement, disrupting spaces and wasting resources. CUALI® Hollow Repair Adhesive offers a non-destructive, long-lasting solution, engineered with advanced epoxy technology to address hollowing at its root.

Versatile Application Scenarios for Every Hollowing Need

Designed to tackle tile hollowing in diverse settings, this adhesive is the go-to choice for both residential and commercial projects, compatible with ceramic tiles, porcelain tiles, marble, granite, and most common substrates:

Residential Spaces: Fixes hollow floor tiles in living rooms, kitchen backsplashes, bathroom walls, and balcony paving. Ideal for addressing issues caused by improper initial installation, temperature changes, or long-term foot traffic.
Commercial & Public Areas: Perfect for high-traffic spaces like hotels, shopping malls, office buildings, and hospitals. Its high strength and durability ensure tiles stay secure even under heavy use and slight structural movement.

Renovation & Maintenance: Ideal for old building restorations, historical property tile repairs, and post-construction touch-ups. It preserves the original tile aesthetic without the need for replacement, saving time and costs.
Moisture-Prone Zones: Excels in kitchens, bathrooms, and laundry rooms thanks to its excellent impermeability (≥1.5MPa) and water resistance, preventing moisture from seeping into gaps and causing re-hollowing.

Core Features Backed by Strict Technical Standards

CUALI® Hollow Repair Adhesive stands out with professional-grade performance, as verified by rigorous testing (per TDS specifications):

Superior Bonding Strength: Adhesion ≥3.5MPa (meets GB∕T 39289-2020 standard) and tensile strength of 40.6MPa (tested with American-made drawing machine). One repair ensures “no more empty drumming,” with a permanent bond that outperforms national standards.
Exceptional Durability: Cures to a hardness of 80D (GBT/2411-2008 standard) and boasts compressive strength ≥55MPa (JC/T1041-2007(2017)). It resists alkali, aging, and temperature fluctuations, maintaining stability in environments from 0℃ to 60℃.
Low Water Absorption: Absorbs only 0.09g in 4 hours (JCT1004-2007), preventing moisture-related degradation and ensuring long-term reliability in humid spaces.
High Penetration: Features a 500% infiltration pressure ratio, allowing it to seep into tiny gaps (as small as 0.1mm) between tiles and substrates for complete filling.

Easy Operation & Efficient Construction

Whether you’re a professional contractor or a DIY enthusiast, this adhesive simplifies the repair process with user-friendly steps (adapted from our TDS):

Locate & Prep: Tap tiles to identify hollow areas, then drill 3-5mm diameter holes (along joints to avoid tile damage). Clean tiles to remove dust, oil, or water.
Mix & Inject: Combine Component A and B per the package ratio (1:1 for 400ML tube; 6:1 for barrel packaging) and stir evenly. Inject the mixture using a special grouting machine or syringe, tapping tiles while pouring to ensure full filling.
Finish & Cure: Seal holes if needed and let cure for 24 hours—then the area is ready for normal use. No tile removal required, cutting construction time by up to 70%.

With a 50-minute bolster time (2kg load) and working time of 20-30 minutes at 25℃, it balances efficiency with flexibility for on-site adjustments.

Environmental Safety & User-Friendly Design

CUALI prioritizes safety and sustainability, making this adhesive suitable for indoor use:

Low Allergy Risk: Uses high-quality curing agents with very low free amine content, reducing skin irritation during construction.
Certified Eco-Friendly: Passes China’s Ten-Ring Certification (a top environmental standard), is non-toxic, and free of harmful formaldehyde.
Safe Construction: Requires only basic PPE (masks, gloves, goggles). Accidental skin contact can be cleaned with alcohol and water; surface residue is easily wiped away before curing.
