Definition
Grouting fills the joints between tiles with a cementitious or epoxy material. It seals the joint against water and dirt and completes the finished look. A 2 to 3 mm joint is common for rectified porcelain, wider for non-rectified tiles.
Why it matters on a project
Grout colour and type change the look of the whole floor, and cement grout in bathrooms and kitchens stains and cracks over time.
Measurement and pricing
Usually included in the tiling rate per square metre, with epoxy listed separately because it costs much more.
Common mistake
Grouting before the adhesive has set, or letting epoxy residue cure on the tile surface where it is hard to remove.
Frequently asked questions
When should I use epoxy grout?
In bathrooms, kitchens, pools and areas that need stain and chemical resistance.
How long before grouting?
Usually 24 hours after laying, or per the adhesive data sheet.
