When you first put in new grout, it gives your fixtures a bright appearance that puts a smile on your face every time you look at it. But over time, grout can begin to look dingy. What’s more, if water or grit gets into the joints of the tile, it can lead to serious problems.
At this point you may wonder if a complete re-grout is necessary or if it would be possible to simply put new grout over old grout. The answer is, yes, it is possible to put new grout over old grout. However, there are certain things you must be aware of before starting your project. Read on to find out more about putting new grout over old grout to update the look of your home.
Benefits of Putting New Grout Over Old Grout
Putting new grout over old grout is not as complicated as a complete re-grout as it does not require the removal of the old grout. It can also strengthen the surface to increase water resistance and make it less susceptible to impurities. However, you must make sure you are re-grouting with the same type of grout you originally used. If not, the second layer will not adhere well to the first and you will have to do the same job over again in a few months’ time.
When you re-grout, you don’t want to create a second layer of grout. Rather, you want the two layers to mingle. This will ensure that the bond is tight, and it will reduce the risk of water, dirt and grime getting in. Therefore, you will want to wipe or chip away any grout that is dirty or crumbling.
If you find any issues that may have led to the grout crumbling, or if there is any mold beneath the surface, deal with those issues before re-grouting to prevent them from occurring again.
Once all that is done, ensure the area is completely clean by using a vacuum on it. Wash the walls and floor until all dust and film is removed.
Re-grout the Tile
The first step to re-grouting is to mix the grout according to package directions. Then spread it on the surface with a grout float. Use the float like a squeegee to force the grout into the joints.
Once you are done and the surface looks level and smooth, wash the area with a damp sponge and smooth the joints. Clean again once the surface is smooth, buff it with a clean towel and let it set for a week. After giving it this rest period, you may apply sealers.
Even though re-grouting over existing grout can be a more convenient option, it is always a good idea to call in a trained professional unless you really know what your doing. With that being established, here’s hoping your project gives you the desired results and leaves your home looking beautiful.
