I re-grouted my bathroom at the weekend and though I’d write a quick how to guide incase any of you wanted to try it as well.

Causes of Grout Discolouration

Unless your shower is a brand new installation, you may well have noticed that the spaces between the tiles are not quite as pristine as the tiles. This is due to dirt getting into the grout, the cement like material that fills the joints between them.

Bathrooms and kitchens are subjected to a wide range of temperatures and particularly in the case of bathrooms, damp. Both will eventually cause the grout to become discoloured.

Removing Grout Build-up

To remove grout it is essential to protect the surrounding tiles with masking tape. You can then use a tool called a grout rake, which can be found in most DIY stores. This is a little like a heavy-duty toothbrush, which enables you to gently scrape the dirt encrusted layer of grout away. Once this has been accomplished, you are ready to apply a fresh layer of grout between the tiles.

Use exactly the same process to tackle grubby tiles in the kitchen. These are liable to suffer from greasy coating as much as the effects of damp, so also wash their surfaces with detergent.
