Trusted Tile Adhesive OEM Solution

Tile adhesives are well-known for their reliability. However, during practical applications, certain issues may arise. For example, insufficient bond strength, tile detachment, and poor durability. And leading to unsatisfactory construction outcomes. These problems stem from the formulation materials and additives utilized in the tile adhesive. Besides, they are influenced by the specific types of tiles and conditions of the substrate surface.


WOTAIchem stands as a leading construction additive factory for tile adhesive solution. Our OEM services have proven beneficial to partners in over 30 countries worldwide. With our innovative additive solution and quality assurance, you can ensure excellent tile adhesive applications. We offer HPMC, HEMC, RDP, HPS, calcium formate, and SM superplasticizer to address tile adhesive application concerns.

What is the difference between C1 and C2 Adhesive?

C1 and C2 adhesives differ in their flexural strength and deformability. C1 adhesives are suitable for bonding ceramic tiles with low deformation. In contrast, C2 adhesives are ideal for natural stone tiles or ceramic tiles with high deformation. C2 adhesives offer better adhesion performance. And increased resistance to external stress compared to C1 adhesives.

Thus, considering the specific tiling requirements and substrate conditions is important. These factors are helpful in ensuring a successful and lasting tile installation.

Hollow Backside of Tiles

It is commonly known as “hollow tiles” or “drummy tiles”. This issue occurs for various reasons:
1. Excessive substrate water absorption.
2. Excessive thickness of the tile adhesive layer. High shrinkage rates can cause hollow spaces to form.
3. Inadequate water retention properties of the tile adhesive itself.
4. Applying tiles after the recommended waiting time.



1. Apply plaster to substrates with higher water absorption rates.
2. Reduce the thickness of the adhesive layer or use larger-sized sand particles.
3. Opt for water-retaining agents with better properties.
4. Adhere to the tiles within the recommended waiting time.

Tile Detachment

Tiles may fall due to various reasons:
1. Excessive hollow spaces can lead to tile detachment.
2. Insufficient bond strength results in tiles falling off.
3. Insufficient adhesion on smooth tile surfaces.
4. Inadequate flexibility and poor thermal expansion and contraction resistance in the tile adhesive.
5. Presence of dust, oil stains, or other contaminants on the substrate.


1. Reduce the occurrence of hollow spaces on the backside of tiles.
2. Select more flexible adhesive powders and adjust the amount used.
3. Ensure thorough cleaning of the substrate surface.

Tiles Slipping During Installation

Addressing tile or stone slipping during tile adhesive application requires a keen understanding of its underlying causes. Two significant factors contributing to this issue are:
1. The tile adhesive mixture is too thin or lacks sufficient bond strength.
2. The weight of tiles or stone slabs is substantial. It requires a bottom-up installation approach.



1. Adjust the formulation materials, opt for cellulose ethers with higher viscosity, or adjust the early-strength
2. Aagent’s quantity. Additionally, adjust the water-cement ratio during mixing.

What Causes Bubbles in Tile Adhesive? Solutions?
Which eco-friendly adhesives are best for sustainable construction practices?
Choosing eco-friendly adhesives is crucial for sustainable construction. WOTAIchem’s cellulose ethers, RDP, and HPS for adhesives are formulated with environmentally friendly materials. These adhesives are free from harmful chemicals and emissions, ensuring healthier indoor air quality. Opting for the best eco-friendly adhesives promotes a greener environment and contributes to long-lasting and secure tile installations.
Can I use cement as floor tile adhesive?
Only using cement as a floor tile adhesive is not recommended. Cement lacks the necessary adhesive properties to securely bond tiles, leading to poor adhesion and potential tile detachment. It’s best to use specialized tile adhesives designed for flooring applications. They are helpful in ensuring a strong and durable bond performance between the tiles and the substrate.
What is a drummy tile?

A drummy tile is a tile that sounds hollow when tapped. It indicates that the tile lacks proper adhesion to the substrate, causing air gaps or voids between the tile and the adhesive layer. This condition can lead to reduced bond strength and potential tile detachment. It’s essential to address drummy tiles promptly to ensure a secure and long-lasting tile installation.

Can I reuse tile adhesive if it exceeds the recommended working time and I add water to it?
No! Reusing tile adhesive after its working time and adding water is not recommended. The adhesive’s active components react during the initial mixing. And attempting to re-mix it later diminishes its bonding strength, potentially leading to tile detachment and safety risks.
What additives are advised for different tile adhesive types? (C1, C2, C2TE, C2S1)
We recommend incorporating specific additives from WOTAIchem’s product range.
For C1 tile adhesives:
– Heavy calcium powder
– RDP powder
– Lignin fiber
– Calcium formate
– Starch ether
For C2TE and C2S1:
– RDP powder
– Corn starch ether
– Calcium formate
Last but not the least! The exact weights and ratios should be customized based on your project’s requirements. Feel free to consult our experts at WOTAIchem for personalized guidance. Our team is here to assist you in achieving optimal results for your unique application.
What can be done about reduced tensile strength in tile adhesive after immersion, especially when meeting the C2 standard is challenging?
Certainly! There are potential solutions to address this issue. One approach could involve considering the addition of hydrophobic agents or adjusting the powder content. While you may inquire about hydrophobic agents similar to calcium stearate, it’s important to note that the effectiveness of such agents in enhancing water resistance might not be significant.


Alternatively, a more effective solution might involve increasing the powder content using WOTAIchem Waterproof RDP Powder. It is specifically designed to improve water resistance properties in tile adhesive applications. This recommendation is aimed at enhancing the overall performance and durability of the adhesive under challenging conditions. For personalized guidance and to determine the best course of action for your specific situation, we encourage you to engage with our experts at WOTAIchem.
What are important considerations during the tile adhesive application process?

Tile adhesive needs to be evenly applied to the back of the tile. Ensure even application of tile adhesive on the tile’s back; rushing or uneven thickness can lead to tile voids.

Therefore, remember these summarized key tips when applying tile adhesive:

1. Apply adhesive evenly for proper bonding.

2. Avoid excessive thickness of uniform tiles.

3. Do not mix adhesive with cement.

4. Use leveling compounds for uneven surfaces.

5. Use dedicated grout for filling gaps.

6. Follow the correct water-to-adhesive ratio.

7. Don’t let the adhesive sit too long before use.

8. Control adhesive application area to prevent drying.
