Power Grout has a unique formulation that has increased stain protection and is resistant to many common stains when cleaned immediately. Prolonged exposure to any stain will increase the likelihood of permanent staining or discoloration of a grout surface. Power Grout provides strong, color consistent joints, that are resistant to shrinking and cracking and it will not contribute to efflorescence. Power Grout provides excellent performance in environments such as high traffic and wet conditions, and in residential and commercial applications.
