Terrazzo Issues: Lifting, Hollowing, Cracking? Causes and Solutions! 💡✨
共有
Recently, many users have asked why terrazzo installations sometimes result in lifting, hollowing, or even cracking. After compiling some practical insights, I’m here to share how to address these common challenges effectively. 🛠️🏠
Why Do These Issues Happen? 🤔
Terrazzo is a cement-based material known for its significant expansion and contraction due to moisture. If the wrong adhesive materials or methods are used during installation, these imbalances often lead to hollowing, lifting, or cracking. 📉
Common Problem Scenarios:
1️⃣ Slow-Curing Tile Adhesive:
After installation, terrazzo panels absorb moisture, causing the bottom layer to swell while the top remains dry and shrinks. This inconsistent deformation leads to lifting, especially at the corners, causing hollowing. 📉
2️⃣ Fast-Curing Tile Adhesive:
While fast-curing adhesives set quickly, they rapidly deplete moisture content. The bottom layer absorbs less moisture and is fixed firmly, while the top layer, exposed to air, gradually shrinks. When shrinkage stress exceeds the tensile strength of the panel, cracking occurs. 💥
Summary:
Whether using slow- or fast-curing adhesives, inconsistent deformation of terrazzo panels often leads to lifting, hollowing, and cracking.
Professional Solution – Choosing the Right Back Glue is Key! 💪
Hanshi 929 Anti-Hollow Elastic Back Glue is a high-performance product specifically designed to tackle terrazzo installation issues. It forms an elastic layer on the back of the stone, absorbing deformation stress and preventing hollowing or cracking. 👏
Why Choose Hanshi 929?
- ✨ Elastic Deformation Adaptability: Provides flexible bonding between the stone and the substrate, reducing stress caused by thermal expansion or contraction. 🪄
- ✨ Superior Waterproofing: 160x the impermeability of standard adhesives, ensuring no moisture infiltration! 💧🚫
- ✨ Eco-Friendly: Non-toxic, low-emission, and safe for use. 🌿✅
Practical Installation Tips 📋
- Clean the Stone Surface: Ensure the back of the stone is free from dust and moisture before application.
- Accurate Mixing: Mix 929 emulsion and cement in a 1:1 ratio using an electric mixer for a smooth, lump-free consistency. ⚙
- Even Application: Use a roller or trowel to coat the stone's back evenly, maintaining a thickness of about 1mm. 🖌️
- Cure Properly: Allow the adhesive to set for at least 24 hours before installation to ensure optimal bonding. ⏳
