Repair any damaged areas: Inspect the surfaces for any cracks, holes, or other damage. If you find any, it’s essential to repair them before applying the mastic. Use a suitable filler or patching compound to fill in the damaged areas and smooth them out. Let the filler or compound dry completely before proceeding.
Prime the surfaces: Depending on the type of surface you are working on, you may need to apply a primer to enhance the adhesion of the mastic. Consult the manufacturer’s instructions or a professional for guidance on which primer to use and how to apply it. Allow the primer to dry completely before moving on to the next step.
Protect adjacent surfaces: If there are any adjacent surfaces that you want to protect from the mastic, such as walls or surrounding fixtures, use masking tape or protective sheets to cover them. This will prevent any accidental spills or smears that may be difficult to clean later on.
By taking the time to properly prepare the surfaces, you are ensuring a better bond and a more successful application of trowel mastic. This will lead to a longer-lasting and more professional-looking finish.
Step 2: Application
Once you have properly prepared the substrate and mixed the trowel mastic, it’s time to start applying it to the surface. Follow these steps to ensure a successful application:
1. Begin in a Corner
Start in one corner of the area you are working on. This will ensure that you have enough space to maneuver the trowel.
2. Spread a Layer of the Mastic
Take a small amount of trowel mastic onto the trowel and spread it onto the substrate. Use the flat edge of the trowel to evenly distribute the mastic over the surface.
Tip: Apply the trowel mastic in thin layers to avoid any unevenness or bumps when installing the tiles.
3. Use the Notched Edge
Once you have spread the initial layer with the flat edge of the trowel, flip the trowel over and use the notched edge to create ridges in the mastic. This will help with the tile adhesion.
Tip: The size of the notches on the trowel will depend on the size of the tiles you are installing. Refer to the manufacturer’s instructions for guidance.
4. Apply the Tiles
Place the tiles onto the trowel mastic, pressing them firmly into place. Make sure the tiles are aligned properly and have consistent spacing between them.
Tip: Use tile spacers to ensure even spacing between the tiles.
5. Clean Up Excess Mastic
As you work, periodically check for any excess mastic that may squeeze through the gaps between the tiles. Wipe away any excess mastic with a damp cloth or sponge.
Tip: It’s important to clean up any excess mastic before it dries, as it can be difficult to remove once hardened.
Continue applying the trowel mastic, creating ridges, and placing tiles until the entire area is covered. Allow the mastic to dry completely before proceeding to the next step of the installation process.
Step 3: Finishing Touches
Once the trowel mastic has been applied and the tiles have been firmly pressed into place, there are a few finishing touches that can be done to ensure a professional and seamless finish.
Clean any excess mastic
Before the mastic dries completely, it is important to clean up any excess that may have squeezed out from the edges of the tiles. This can be done using a damp sponge or cloth, gently wiping away the excess mastic. Be careful not to disturb the position of the tiles while doing this.
Smooth out the mastic lines
To achieve a clean and professional look, it is recommended to smooth out the lines of mastic between the tiles. This can be done using a finger or a silicone smoothing tool. Gently run your finger or the tool along the lines of mastic, smoothing them out and creating a seamless appearance.
Note: It is important to smooth out the mastic lines while the mastic is still wet. Once it dries, it becomes hard and difficult to work with.
Allow the trowel mastic to dry completely according to the manufacturer’s instructions before grouting the tiles. This usually takes around 24 hours, but may vary depending on the specific product being used.
By following these steps and taking the time to properly finish the installation, you can ensure a smooth and professional looking tile surface that will last for years to come.
