After a few years of constant use, the grout on your shower tiles will show wear and tear. You cannot prevent the grout from getting discolored after a time. Soap scum, mildew and mold may also have done some damage to the tile. Weather changes can also cause some damage to the grout. With the right tools on hand it is possible for you take up the project yourself. Below are the things you have to do to be able to regrout shower tile.
- There are many colors of grout that are available today aside from the basic white so you can coordinate the grout color with the color of your shower tiles.
- Clean your shower tiles first with your usual cleaning solution and wipe the tiles dry. Look for a cracked grout or chipped portion so you can easily start off removing the old grout. Use a grout removal tool to chisel off the grout. Be careful that you do not damage the shower tiles. The corners of the tiles are very vulnerable. It is best that you remove as much as you can of the old grout to ensure a better seal.
- Use a stiff brush to remove grout dust and chips from between the shower tiles. The new grout will adhere firmly when the spaces between the tiles are very clean. This is also your chance to replace old and cracked shower tiles so if there are any that needs to be replace, remove them carefully and clean the surface as well. Replace the damaged tiles first.
- Clean the shower tiles once again to make sure that grout dust does not coat the surface. Use an antibacterial cleaning solution to ensure that mold and mildew spores will be destroyed. Make sure that the shower tiles and the gaps between tiles are very dry before applying grout.
- Use professional-grade grout and additive to ensure that the grout will last longer than other commercial and pre-mixed varieties. Follow the manufacturer’s instruction on what is the proper proportion of grout powder and additive. Apply the grout with a grout float and minimize excess grout from covering the tiles by going carefully over the lines or gaps between the tiles. Wipe off the excess grout from the tiles and along the lines with a damp sponge five minutes after you have finished applying the grout. Do this several times until no trace of the grout mixture is visible on the shower tiles.
- The grout will completely cure after two to three days. Do not let anyone use the shower stall while you waiting for the grout to completely dry.
- Apply three to four coats of silicon sealant over the grout, waiting a few minutes after each application and removing the excess with a white cloth. The shower stall should be off limits for another three days to allow the sealant to completely dry and seal the grout to prevent moisture from seeping through.
Plan to regrout shower tile when you have good weather to ensure that grout and sealant will cure better. Be sure that you wear protective face mask when removing the grout and when handling chemicals.
