This is a very frequently asked one. The answer is that if you use a Grout Sealer then this will help keep the grout looking like new for a longer period of time. It will also make the cleaning process much easier because any dirt will be kept at the surface and hence will be easier to wipe away. Using grout sealer will also prevent the growth of mildew because the pores in the grout will be sealed and make it much tougher for mildew and mould spores to prosper.
