Type 1 and Type 2 Tile Adhesive and Their Uses

Ⅰ. Types of Tile Adhesive


There are types of tile adhesives, and they serve different purposes. So, what is c1 and c2 tile adhesive?


Type 1 tile adhesive (C1 tile adhesive) is a general-use adhesive for installing ceramic, porcelain, and natural stone tiles. It is a cement-based and dry mix material that you can mix with water before applying it with a trowel. Type 1 is most frequently used for indoor and outdoor applications, including walls and floors. However, it has relatively low waterproofing ability, as it’s not recommended to use for bathroom areas. More suitable for kitchen, living room, and bedroom tiles.


Type 2 tile adhesive (C2 tile adhesive) is a modified cement-based adhesive. Particularly designed for wet areas such as showers and pools. It has a strong waterproofing capacity and is resistant well to mold. Thus, type 2 tile adhesive is more suitable for areas that are consistently exposed to extreme weather.


Here, let’s discover the major differences between Type 1 and Type 2 tile adhesives!

Ⅱ. Type 1 vs. Type 2 Tile Adhesive


Type 1 Tile Adhesive>>

  • Composition: Cement-based adhesive mixed with water and apply with a trowel.
  • Applications: Generally used for installing heavy tiles, such as ceramic, porcelain, and natural stone tiles.
  • Application areas: Both indoor and outdoor projects, walls and floors.
  • Type 1 tile adhesive drying time: 24-48 hours.
  • Cost: More affordable.

Type 2 Tile Adhesive>>

  • Composition: Modified cement-based adhesive formula. Enhanced flexibility and resistant to mold and mildew.
  • Application: Same method with Type 1, but requires less water to reach higher flexibility.
  • Application areas: Designed specifically for wet areas such as showers and pools.
  • Type 2 tile adhesive drying time: 24-48 hours.
  • Properties: More resistant to cracking. Durable in extreme temperatures.
  • Cost: Typically more expensive than Type 1.


Key Differences

1. Cement Type:

– Type 1: Made with Portland cement, suitable for most general applications.

– Type 2: Uses modified cement for better flexibility and water resistance.


2. Water Requirements:

– Type 1: Requires more water to achieve the right consistency.

– Type 2: Needs less water, enhancing its resistance to water and temperature changes.

3. Cost:

– Type 1: More affordable, ideal for a wide range of standard uses.

– Type 2: More expensive, designed for high-moisture areas and extreme conditions.

Type 1 tile adhesive is a general-purpose adhesive suitable for most tiling projects, both indoors and outdoors. In contrast, Type 2 tile adhesive is formulated for wet and demanding environments, providing greater flexibility and resistance to mold, mildew, and cracking. The primary differences lie in the type of cement used and the water requirements, with Type 1 being more cost-effective and Type 2 offering specialized benefits for wet areas.

Ⅲ. Type 1 Tile Adhesive for Shower


Now we know the major difference for type 1 and type 2 tile adhesive, so can we use type 1 tile adhesive for shower?

The answer is NO. We should not use Type 1 tile adhesive for a shower.


Type 1 adhesive is not designed to handle constant exposure to water and moisture. In a shower, where it is always wet, Type 1 adhesive can weaken, leading to tiles coming loose or falling off. Instead, use Type 2 tile adhesive, which is specially made to be water-resistant and flexible, making it ideal for wet areas like showers.

If you want the tilling in shower areas to last a long time, then type 2 is more recommended to choose.

Ⅳ. Type 1 Tile Adhesive vs. Mortar


Type 1 tile adhesive and mortar are both used for laying tiles. However, they’re made of different materials. And they worked differently as well.

Type 1 tile adhesive is a ready-mixed adhesive. It is made of a blend of cement, polymers, and other admixtures. It’s convenient to use as you only have to add water to mix it before applying it with a trowel.


Mortar, on the other hand, is a cement-based mix you can also mix with water. Sometimes, it is also called tile mortar or thin-set mortar. Specially used for tile installation. It requires mixing with water to achieve the right consistency. Apply it directly with a trowel. The same method, just like how you apply Type 1 tile adhesive. However, the mortar is suitable for large and heavy tiles especially, and for outdoor installations and areas that are exposed to moisture. Mortar offers excellent durability and is resistant to water and temperature changes. For example, if you need to set tiles in high-traffic areas or set natural stone tiles, you may want to use mortar instead. Mortar with added admixtures such as HPMC and RDP powder, then you have a perfect tile adhesive formula that can last for decades.

V. Best Adhesive for Ceramic Tiles

What is the best adhesive for ceramic tile? Choosing the best adhesive for ceramic tile depends on several factors, application, location, and type of tiles you are using.

For most ceramic tile installations, especially for floors or wet areas, thinset mortar is the best choice because it is strong, versatile, and durable. With certain mortar admixtures provided, you can start an inquiry and get to know more.

Type 1 and Type 2 adhesives are good for simpler projects, with Type 2 being slightly better for areas with some moisture.
