Once you have installed the marble tile backsplash, grouting is necessary for finishing the installation. Grout is the material that fills up the space between the marble tiles, supporting the grid. The grout acts as glue and it also makes the tiling look good. It is very easy to grout a marble top backsplash and this is the easiest part of the whole installation process. You can do this on your own very easily and it takes very little time.
Step 1: Choosing the Grout
There are mainly three types of grout available in the market, the cement based, epoxy based, furan resin based grouts. Among these types the grouts are classified as non-sanded and sanded. The sanded grouts are used for larger joints while the non-sanded ones are used for joints smaller than 1/8 inches in width. For tile marble backsplash it is better to use the non-sanded grout. The cement grouts are easy to apply and clean while the epoxy ones are durable and also more expensive. You can also go for the caulking grout. They come in a tube and you can squeeze it out from the tube directly for application or use a caulking gun.
Step 2: Mixing the Grout
After you have purchased the appropriate grout you need to mix it. For this use the mixing bucket and, if it is cement based, use water for mixing it or in case of furan resin grouts use alcohol. Follow the manufactures direction very carefully and mix it.
Step 3: Application
For applying the grout mixture on the marble tile backsplash use the grout float. You need to apply the grout mixture section by section and must be very careful about covering the joints completely. Take a small amount of grout mixture on the float and align it at an angle of 45 degrees with the backsplash. Make several passes over the joints so that the joints are completely filled up. In the case of non-sanded grouts you do not need to worry about scratching the marble tile and thus you can apply it very quickly.
Step 4: Wipe the Marble Tile Backsplash
Once the grout is applied over the joints the grout also covers portion of the tiles. Use a wet sponge for removing the grout from the tiles and make it clean. You need to wipe it several times for cleaning it completely. Allow the grout to dry and follow the manufacturer's instruction for the time that is required for drying the grout. Make sure the sponge you are using is clean and free of any sand particle, otherwise it may cause scratches.
Step 5: Finishing the Process
When the grout is completely dry you will notice that there are still small amount of grout particles present over the tiles. Use an old rag or tack cloth to clean it completely.
