While using a primer is usually recommended, there are certain situations where it may be possible to skip this step:
- Solid and Smooth Concrete Surface: If your concrete floor is in excellent condition, without any noticeable irregularities or excessive porosity, you may be able to skip applying a primer. However, it is still advisable to consult with a professional to ensure that your concrete surface is suitable for direct thinset application.
- Properly Sealed Concrete: If your concrete floor has been adequately sealed with an appropriate concrete sealer, it may already provide a suitable surface for thinset application. Sealing the concrete helps reduce its porosity, creating a surface that allows for proper adhesion.
It is essential to note that the decision to skip using a primer should be made after careful consideration and consultation with professionals. Factors such as the type of tile being installed, the condition of the concrete, and existing moisture levels should all be taken into account.
While it is generally recommended to use a primer when installing tile on a concrete floor, there may be situations where it is possible to skip this step. The use of a primer enhances adhesion, reduces moisture absorption, and improves the durability of the tile installation. However, if the concrete surface is solid, smooth, and properly sealed, it may provide a suitable substrate for thinset application without the need for a primer. Remember to consult with professionals and consider various factors before making a final decision.
