Can You Put Tile On OSB Subfloor?

Oriented strand board (OSB) is a type of structural panel that is commonly used as a subfloor in residential construction. It is made from wood strands that are bonded together with resin. OSB is a strong and durable material, but it is not waterproof. Therefore, it is important to use a moisture barrier between the OSB subfloor and the tile.

There are two main types of moisture barriers that can be used with OSB subfloors: felt paper and plastic sheeting. Felt paper is a traditional moisture barrier that is made from recycled paper. It is inexpensive and easy to install, but it is not as effective as plastic sheeting. Plastic sheeting is a more modern moisture barrier that is made from polyethylene. It is more expensive than felt paper, but it is also more effective at preventing moisture from penetrating the OSB subfloor.

Once the moisture barrier has been installed, you can begin to install the tile. It is important to use a thin-set mortar that is specifically designed for use with OSB subfloors. This type of mortar will help to prevent the tile from cracking or popping up.

Here are the steps on how to install tile on OSB subfloor:

Prepare the subfloor by cleaning it and making sure that it is level.
Install a moisture barrier over the subfloor.
Apply a thin-set mortar to the subfloor using a notched trowel.
Set the tile into the mortar and press it down firmly.
Grout the tile joints.
Seal the grout to protect it from moisture.

By following these steps, you can successfully install tile on an OSB subfloor.

Additional Tips

Here are a few additional tips for installing tile on OSB subfloor:

Use a backer board over the OSB subfloor if the subfloor is not level or if you are installing large tiles.
Use a self-leveling compound to level the subfloor before installing the tile.
Allow the tile to cure for at least 24 hours before walking on it or grouting the joints.
Seal the tile and grout to protect it from moisture.

By following these tips, you can ensure that your tile installation is successful and long-lasting.
