Mapesil T may stain porous materials. Test a small area for staining or leaching before use to ensure compatibility with such porous materials as natural stone. Mapesil T should not be used in areas where material may come in contact with plasticizers or other materials that will prevent or diminish adhesion. Do not use Mapesil T for structural glazing. Not for use in expansion/movement joints with greater than 25% movement. For joints with depth greater than 1/2" (12 mm), the caulking depth must be controlled by a closed-cell backer rod. Joint widths should not exceed 1" (2,5 cm). Although Mapesil T is color-matched to MAPEI’s grout color palette, expect a slight variation in color due to the difference in composition between materials. Not paintable; painting should be done before installation of Mapesil T.
