How to Finish a Fireplace Hearth

What You'll Need
Penetrating grout, tile or stone sealer

Finishing the fireplace hearth will greatly improve the look and design of your fireplace. It will make it more complete and aesthetically pleasing. Aside from this, it will also be easier to clean and staining can be avoided. Even before starting this project, you have to know that it is very important to start with a clean surface, since any dirt or soot that remains will be locked in when you start the finishing process.

Step 1: Clean the Surface

Use the vacuum to clean the surface of the fireplace hearth. This should be clean before you start anything. It should not contain any dirt or soot, because as mentioned above, any dirt, grime or soot will be trapped within the finish, resulting in a messy job and weak finish. Get the sponge and wet it with water, but just keep it damp. Wipe the surface using the damp sponge, gliding it across to remove any stubborn dirt attached to the tiles. When most or all of the dirt has been removed, leave it for a few moments to dry.

Step 2: Seal the Tiles

3 types of tiles could have been used for the pavement of the surface of the fireplace hearth, and all of them need to have an application of a penetrating grout, tile or stone sealer. The 3 types of possible tiles used are glazed, stone-quarried and stone pavers. For glazed tiles, only the spaces in between the tiles have to be applied with grout sealer. As for the other 2, the entire surface has to be sealed with tile or stone sealer because of their rough finishes. Use a kitchen sponge in applying the appropriate sealer, if the surface is rough, or a toothbrush when applying along the grout lines. To make application faster, you may opt to use a roller or paint brush. Make sure that you apply evenly, and that the sealer is equal all throughout the surface of the fireplace hearth. After covering all of the tiles, wait for a couple of hours to let the sealer dry.

Step 3: Apply Clear Sealer

After the sealer has dried , it’s now time to apply the clear glossy or masonry sealer over the fireplace hearth. Apply it the same way that you applied the first sealant, spreading an even layer over the tiles. This kind of sealers provide a much thicker layer, that completely seals the hearth, and prevents dust particles from penetrating. It also provides a smooth finish, which makes it easier to clean, and gives the hearth that lasting appeal. Wait for the sealer to dry, and you have your finished fireplace hearth project.

Step 4: Cleaning Up

Once all of the clear sealer has been applied, it’s time to clean up. Make sure that it’s already dry. Again, use the vacuum cleaner and clean the whole area of any excess dried up sealer that’s lying around. Get a wet towel or rag and run it across the surface to clean any stubborn dirt and dust that could not be picked up by the vacuum. Enjoy the shine of your newly finished fireplace hearth.
