Regrouting a tub or shower can sound hard, but in reality it is fairly simple grunt work. Often the process is fairly easy and even someone who haven’t grouted tile before can generally complete a complete shower re-regrout within a single day. If there is any confusion about what you are doing, it is a simple matter of checking the directions. Most tile setters will provide a detailed explanation of what is involved in the job and if they do not it is very simple to find someone who will.
What is important to remember when cleaning a tile shower or tub is the fact that you do not need to use harsh abrasive chemicals to clean it. When you are cleaning the grout on the inside of your tub, you should use a scrubbing brush and a mild solution to clean it. Once you have the grout on the inside of your tub, you should clean it with hot soapy water to remove any soap residue and to help clean out any left dirty spots. Once you have scrubbed the entire area you should rinse the area with clean water to remove all soap residues and then rinse the tub again with warm water. Finally you should place a face mask over the area and let the tub dry for about ten minutes before removing it.
In order to regrout a shower or bath you will also need a good quality high pressure washer, a wet/dry shop vac, a bucket, a scrubbing brush, a face mask, a scrubbing sponge, and a high quality ceramic tile caulk. To begin you should position the wet/dry shop vac over the area where the tile is installed and turn on the nozzle. Use the pressure on the handle to pump the shop vac through the whole of the area. Be careful to not squeeze the handle too hard as this could cause damage to the grout. Next you should use the scrubbing brush and a solution of half vinegar and half water to clean out any areas that are not clean. Lastly you should put a mask on and let the tub dry for about ten minutes before removing it.
