Differences between acrylic and urethane grout
 

What are the major differences between acrylic and urethane grout?
Warrenty?
Stain resistence?
Flexibility?

Thanks

differences between acyrlic and urethane grout
 

Both the urethane and acyrlic grouts are pre mixed, easy to use. Both are stain resistant and don't require a sealer. If I'm installing a commercial job or installing the 18x18 tiles I would use the urethane grout. It's required for commercial applications to maintain the warranty and personally I just think the clean up is easier than the acyrlic.

1, erythromycin,

Grouting
 

I've had really good luck using Krud Kutter to clean urethane grout film and mineral spirits for acrylic grouts. Krud Kutter has a very low odor, But I've heard it's difficult to get in Canada. You can also use Goof-Off, but it has more of an odor. And we all know what mineral spirits smell like! use only where in well ventilated areas.
Remember to work in a small area at at time when grouting!
