100%-Silicone Sealant with Enhanced Adhesion for Heavy Traffic and Expansion/Movement Joints

Mapesil T Plus is a professional-grade, 100%-silicone sealant with enhanced adhesion for use on multiple substrates. This product is specifically formulated for heavy traffic and expansion/movement joints exceeding both ASTM and ANSI standards.


FEATURES AND BENEFITS • Color-matched to MAPEI’s color palette • Formulated to a low sheen to match the gloss of grout joints • Rated for heavy-traffic and expansion/movement joints • 100% silicone for use in interior, exterior, wet and dry installations from Res 1 to Res 7 and Com 1 to Com 7 as detailed per TCNA Environmental Exposure Classifications • Excellent elongation and flexibility for use in both change-of-plane and joint applications in tile or stonework • Can be used in pools and spas. 7 days of curing time is needed before pool filling. The resistance of Mapesil T Plus to chlorine is dependent on the pH value of the water and the amount of free chlorine. A pH value between 6.5 and 7.6 is required, and the free chlorine should remain less than 5 mg per L (5 ppm). • Helps to prevent mold and mildew

WHERE TO USE • Interior/exterior residential and commercial installations from Res 1 to Res 7 and Com 1 to Com 7 as detailed per TCNA Environmental Exposure Classifications • As a flexible barrier/filler between horizontal/vertical surfaces and any other changes of plane • Expansion joints in non-traffic, normal-traffic and heavy-traffic areas • Countertops, vanities, sinks, bathtubs, showers, steam rooms, pools, spas, backsplashes and fixtures

LIMITATIONS • Application temperature range is 40°F to 90°F (4°C to 32°C). For some installations, additional time beyond 24 hours may be required before Mapesil T Plus reaches a hardness where light fingernail pressure does not leave an indentation. • Mapesil T Plus 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 Plus 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 Plus for structural glazing. • Mapesil T Plus is not for use in expansion/movement joints with greater than 25% movement. The exception is #23 Clear color, which can be used in joints with up to 50% 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 Plus 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 Plus.
