Who this guide is for
- Homeowners choosing grout for a tiling project
- People comparing cement, epoxy and urethane grout
- Anyone wanting stain-resistant, easy-clean joints
- Homeowners briefing a tiler
What grout does and why it matters
Grout fills tile joints, but its material affects stain resistance, cleanability and how the surface handles movement and moisture. Poor grout choices show as discoloured, crumbling or stained joints.
Match the grout to the tile location and conditions, since a wet, busy area asks more of grout than a dry one.
- Grout affects stains, cleaning and movement
- Poor choices show as stained, crumbling joints
- Match grout to the location and conditions
Cement-based grout
Cement grout is the traditional, widely used option and suits many situations, but it is porous, so it can stain and may need sealing to resist grime in wet or busy areas.
It is versatile and familiar; its main limitation is that it absorbs more than denser grouts unless sealed and maintained.
- Traditional and widely used
- Porous, so can stain without sealing
- Versatile but needs maintenance in wet areas
Epoxy grout
Epoxy grout is dense, stain-resistant and hard-wearing, which suits wet and high-traffic areas where cement grout struggles. It resists grime and is easy to keep clean.
Epoxy is more demanding to work with, which is part of why its application is best left to a skilled tiler.
- Dense, stain-resistant and hard-wearing
- Suits wet and high-traffic areas
- More demanding to apply
Urethane and other modern grouts
Urethane and other modern grouts aim to combine stain resistance and flexibility with easier handling than epoxy. They sit between cement and epoxy for many uses.
These options are worth weighing for areas wanting performance without epoxy's working demands; compare with a tiler for your project.
- Combine stain resistance with easier handling
- Sit between cement and epoxy
- Compare with a tiler for your project
Color, joint width and maintenance
Grout color and joint width strongly affect the tiled look: contrasting grout emphasises the pattern, matching grout calms it. Lighter grout shows grime faster.
Plan maintenance with the grout choice, since some grouts need sealing and care while others are lower-maintenance.
- Color and joint width shape the look
- Lighter grout shows grime faster
- Plan maintenance with the grout choice
Grout checklist
- 1Match grout to the tile location and conditions
- 2Consider cement grout's need for sealing in wet areas
- 3Consider epoxy for stain resistance in wet, busy spots
- 4Consider urethane for performance with easier handling
- 5Weigh grout color against showing grime
- 6Plan joint width for the look you want
- 7Plan maintenance to suit the grout type
- 8Discuss demanding grouts with a skilled tiler
- 9Coordinate grout with the tile and palette
- 10Brief a tiler on the grout and conditions
Common mistakes to avoid
- Using porous cement grout unsealed in a wet, busy area
- Choosing light grout that shows grime quickly
- Ignoring how much movement and moisture the area sees
- Underestimating the skill demanding grouts require
- Picking grout color without considering the tile look
- Skipping the maintenance a grout type needs
When to involve a professional
- Use a qualified tiler for grouting, especially demanding grout types
- For wet areas, confirm waterproofing and grout choice with a professional
- Treat any tile or substrate movement problems as work for a qualified trade
- Requirements vary by location and project, so confirm specifics for your home
Frequently asked questions
Questions readers ask about this topic
What is the difference between cement and epoxy grout?
Cement grout is traditional and versatile but porous, so it can stain and may need sealing in wet or busy areas. Epoxy grout is dense, stain-resistant and hard-wearing, suiting wet, high-traffic spots, but it is more demanding to apply. The right choice depends on the location.
Is epoxy grout worth it?
Epoxy grout's density makes it stain-resistant and easy to keep clean, which is valuable in wet and high-traffic areas where cement grout struggles. It is more demanding to work with, so its application is best left to a skilled tiler, but the performance can justify it.
What grout resists stains best?
Dense grouts such as epoxy resist stains best because they absorb far less than porous cement grout. Urethane and other modern grouts also offer good stain resistance with easier handling. In wet, busy areas, a stain-resistant grout keeps joints looking clean for longer.
Does grout color matter?
Yes. Grout color and joint width strongly affect the tiled look: contrasting grout emphasises the pattern while matching grout calms it. Lighter grout shows grime faster, which is worth weighing in busy or wet areas where cleanliness is a priority.
