1. The Pain Points of Traditional Tile Adhesive & Mortar
Many construction projects still use traditional tile adhesive or mortar made with cement, sand, and low-quality binders. These products often have the following problems:
-
Poor Bond Strength: Traditional binders have weak adhesion to tiles and concrete substrates, leading to tile hollowing and peeling over time—especially in wet environments (e.g., bathrooms, kitchens).
-
Lack of Flexibility: Rigid binders cannot adapt to slight substrate deformation (e.g., concrete shrinkage, temperature changes), resulting in tile cracking and mortar peeling.
-
Poor Water Resistance: Traditional mortar absorbs water easily, leading to reduced bond strength and durability in wet or outdoor environments.
-
Difficult to Construct: Traditional mixtures are prone to sagging, require high skill levels for application, and have a short open time (the time available to adjust tiles after application).
These problems not only increase maintenance costs but also affect the safety and aesthetics of the project. The solution? Add high-quality VAE emulsion to tile adhesive and mortar.
2. Why VAE Emulsion is the Best Binder for Tile Adhesive & Mortar
VAE emulsion is specifically designed to address the shortcomings of traditional tile adhesive and mortar. Here’s how it improves performance and solves common pain points:
Enhances Bond Strength Significantly
VAE emulsion has strong adhesion to both porous substrates (concrete, cement) and non-porous substrates (ceramic tiles, glass tiles). When mixed with cement and sand, VAE emulsion forms a dense film that penetrates the substrate pores, creating a “mechanical bond” that is far stronger than traditional binders. This ensures that tiles stay firmly in place, even in wet or high-traffic areas.
Our VAE emulsion for tile adhesive has a bond strength of ≥1.5 MPa (tested according to GB/T 14074-2017), which is 30-50% higher than traditional binders.
Improves Flexibility & Crack Resistance
One of the biggest advantages of VAE emulsion is its excellent flexibility. After drying, the VAE film remains flexible, allowing the tile adhesive to adapt to slight substrate deformation (e.g., concrete shrinkage, temperature changes). This prevents tile cracking and mortar peeling, even in outdoor or high-temperature environments.
For exterior tile projects, VAE emulsion also improves frost resistance—preventing the mortar from cracking due to freeze-thaw cycles in cold climates.
Boosts Water Resistance & Durability
VAE emulsion contains ethylene monomers, which form a water-resistant film when dried. This makes the tile adhesive and mortar resistant to water absorption, ensuring long-term durability in wet environments (e.g., bathrooms, swimming pools, outdoor plazas). Unlike traditional mortar, which softens when wet, VAE-modified mortar maintains its strength and bond even after prolonged exposure to water.
Makes Construction Easier & More Efficient
VAE emulsion improves the workability of tile adhesive and mortar—making it easier to mix, apply, and adjust. It increases the open time (up to 3-4 hours), allowing workers to adjust tiles more easily after application. It also reduces sagging, ensuring that tiles stay in place during installation—saving time and labor costs.
3. How to Choose the Right VAE Emulsion Grade for Tile Adhesive & Mortar
Not all VAE emulsions are suitable for tile adhesive and mortar. The key is to choose a grade with the right technical indicators, based on your project’s requirements (indoor/outdoor, wet/dry environment, tile type).
Here are the key technical indicators to consider:
Viscosity
For tile adhesive, the recommended VAE emulsion viscosity is 1000-5000 mPa·s (25℃, ND-1 rotational viscometer). Higher viscosity improves the adhesive’s sag resistance, while lower viscosity is easier to mix and apply. For exterior mortar, a higher viscosity (3000-5000 mPa·s) is recommended to ensure durability.
Solids Content
The solids content of VAE emulsion directly affects bond strength. We recommend a solids content of 50-55% for tile adhesive and mortar—this ensures a dense film and strong adhesion. Lower solids content may reduce bond strength, while higher solids content may increase costs unnecessarily.
Glass Transition Temperature (Tg)
Tg is a key indicator of flexibility. For tile adhesive, the recommended Tg is -10℃ to 0℃—this ensures the adhesive remains flexible even in low temperatures. For exterior projects in cold climates, a lower Tg (-15℃ to -10℃) is better for frost resistance.
pH Value
The pH value of VAE emulsion should be 6.5-8.5, which is compatible with cement and other additives. A pH value outside this range may affect the setting time of cement and reduce bond strength.

5. Case Study: How Our VAE Emulsion Improved Tile Adhesive Performance
A construction company in Southeast Asia was facing problems with tile peeling in a residential project—traditional tile adhesive had poor bond strength and water resistance, leading to customer complaints. After switching to our VAE-707 emulsion, the tile adhesive’s bond strength increased by 40%, and there was no more peeling or hollowing even after 2 years of use. The company also reported a 15% reduction in labor costs due to easier construction.
