Have any questions? We’re here to help you out.

Can I use tile adhesive instead of mortar?

You can use tile adhesive as an alternative to traditional mortar for certain applications.


Tile adhesive is also known as thinset. It is designed for bonding tiles to substrates such as concrete, cement boards, and even existing tiles. It offers strong adhesion properties and is suitable for both interior and exterior tile installations.


However, it’s important to know that tile adhesive may not be suitable for all situations. The areas with high moisture or temperature fluctuations can not use tile adhesive to replace the mortar.


For optimal performance, professional mortar tailored to specific situations is recommended. If you have any further questions, feel free to consult with us anytime.
