Can Pool Mosaics be Installed on a Finished Pool?

While it's generally recommended that pool mosaics be installed before plastering your pool, they can be installed after the fact. That said, it's important to point out that there will be a small lip around the mosaic, causing it to stick out of the shell. We're going to explore the installation process of both methods.

Preparing for Your Mosaic Installation

Planning is essential before starting any swimming pool mosaic installation. Consider the design, gather your materials, choose the location for your mosaics, and prepare your workspace. This will make the process smoother and prevent common problems.

Essential Materials and Tools for Mosaic Installation

Having the right materials and tools is essential for a successful installation. For submerged applications, use a thin-set mortar specifically designed for such environments. If you’re working on a finished pool, consider using a tile adhesive like Litoelastic EVO, a high-performance tile adhesive tailored for wet conditions that bond well to a variety of materials.

Ensure you have clean water and sponges on hand for easy cleanup. Essential tools include a notched trowel, grout float, and scissors. Depending on the mosaic style, you might also need rubber gloves and a scrub brush. For swimming pool mosaics installed before plastering, the grouting is typically done with the plaster after that stage of construction. However, if the pool is already finished, epoxy grout is a better choice for grouting, as it helps protect the mosaic and ensures a lasting finish.

How to Install Pool Mosaics: Step-by-Step

Now, it's time to install your pool mosaics. We've planned, gathered materials, and prepped the surface.

Installing Your First Mosaic Section

Trim any excess backing around the mosaics. This allows for full adhesion of the thin-set mortar. Then, back-butter the first mosaic section for a better grip, if necessary. Smaller mosaics may be a single piece, while larger, more elaborate designs can come in multiple parts. Pay close attention to those mosaics to place them in the correct order. Gently press the first piece onto the prepared surface. Use a level to ensure correct placement.

Repeating for All Mosaic Sections

Repeat the previous steps for all remaining sections. Remember to maintain consistent spacing and leveling. Pool chemistry can affect installation, so maintain proper water balance.

Cleaning Up Excess Materials

Clean up any excess mortar using your trowel. You want to try to get as close to the perimeter of the mosaic as possible without getting rid of any material directly under it. This will prevent issues during grouting.

Grouting Your Pool Mosaics

Grouting can damage your mosaic artwork if not done correctly. Follow the manufacturer's instructions carefully. This prevents damage during installation. As previously mentioned, if installed before plaster, pool mosaics are usually grouted using the same plaster applied to the pool shell. However, when installing it after a pool has been constructed, we recommend an epoxy grout. Be sure to choose a color that doesn't compete with the mosaics, so it doesn't ruin the design.  

Mixing and Applying the Grout

Mix the grout according to the package directions. Depending on your pool finish, grouting techniques may vary. Use the appropriate trowel to apply the grout.

Fill all grout lines for a smooth finish. Make sure all of the grout lines are properly filled to create a professional-looking project.

After grouting, carefully remove any excess grout residue. Improper cleaning can cause problems later. Be sure to follow the manufacturing instructions and pay close attention to curing times. It's tempting to refill the pool immediately, but proper curing is crucial.
