Emseal 25V - primary vertical expansion joint seal in masonry where black reveal or shadow-line effect is desired

Sika Emseal 25V is a long-term, economical, high-performance seal for above-grade wall joints in concrete, brick, stone, etc. where black reveal or shadow-line effect is desired or where installed in concealed conditions.

Note: The 25V System has been largely replaced for vertical joint applications by Seismic Colorseal®. While Seismic Colorseal is usually chosen in preference to 25V, 25V still exists in legacy specifications and continues to be a preference of some specifiers for its appearance.
