Emseal 25V - 1 per LF

Primary seal in masonry where black reveal or shadow-line effect is desired.

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 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.

Features

  • Durable primary seal
  • Permanently elastic and weathertight
  • Follows joint contours
  • Difficult to vandalize

Uses

  • A weather, moisture, vapor, air, sound and dust seal in static or expansion/contraction joints in walls.
  • Generally used as a primary seal
  • Can be used as a secondary seal behind a backerrod (or bond breaker tape) and caulking
  • Suitable for use in substrates of brick, CMU, precast and cast-inplace concrete, wood, stone and most construction materials
  • Used extensively for sealing vertical abutment joints between buildings, brick and CMU control joints, joints in tilt-up panels, etc.
  • Anti-vibration and acoustic seal

Sizes

1/4″ (6mm) to 4″ (100 mm)

Movement

+25%, -25% (50% total) of nominal material size

Color

Black

Composition

Permanently elastic, high-density, open-cell polyurethane foam, impregnated with water-based, polymer-modified asphalt.

Design Considerations

Substrates must be clean, parallel, plumb, have sufficient clear depth to receive the material specified, and be capable of resisting approx. 2.5 psi backpressure from the foam.

Maintenance

  • As with any construction product, the useful life of the material can be maximized with routine inspection and repair if required.
  • Occasional inspection will reveal any damage to the product or adjacent substrates that might affect building performance.
  • EMSEAL precompressed sealants are easily repaired–requiring only damaged sections to be removed and reinstalled–not the entire length of the joint as is typical of extruded-seal systems.
