Watertight Expansion Joints and Construction Sealants by EMSEAL


Paintable, precompressed, primary joint sealing system for quick and safe grindless, noiseless, tensionless retrofit installation into EIFS, precast, concrete, and other joint substrates

A joint sealing system for EIFS, precast, concrete, and virtually any substrate, SafeReseal® by Sika Emseal is a safer, grindless, dustless, quiet, primerless, tensionless, paintable, retrofit joint sealant that installs over old sealant residue without the requirement for grinding to completely remove old sealant.

SafeReseal can also be used in new construction as a durable, paintable/coatable alternative to traditional liquid sealant and backer rod.

SafeReseal is factory coated with a premium grade, watertight, paintable, hybrid STPE sealant (SikaHyflex®-150 LM) and precompressed to less than the nominal material/joint size.

The SikaHyflex® sealant has been tested to achieve the requisite adhesion—while under compression from the backpressure of the impregnated foam backing—to the residue of a wide range of commonly supplied joint sealants regardless of age or state (cured, crazed, dried out, reverted, etc.).

Emseal SafeReseal can be installed in a variety of conditions without the need for grinding joint substrates. The elimination of grinding means less noise and less tenant/occupant disruption. The absence of dust means the absence of harmful airborne contaminates like silica and removes the requirement for dust containment, extraction equipment, or specialized respiratory personal protective equipment.

Old joint sealant is removed from the joints using a razor knife. Care is taken to remove as much old sealant as possible without damaging the underlying substrate. After a light solvent wipe, the old sealant is encapsulated with a tooled bead of the supplied SikaHyflex-150 LM sealant which acts as the mounting/bonding adhesive for SafeReseal.

The performance properties of SafeReseal are the same as those in Emseal’s technology-defining, Seismic Colorseal precompressed foam technology. The single preformed product outperforms other technologies and provides a durable, watertight seal that creates a thermal block, acts as a sound attenuating barrier, and resists the effects of air pressure differentials, wind-driven rain, and other common forces that cause moisture ingress.

Paintable – SafeReseal is coated with SikaHyflex® 150 LM STPE hybrid sealant in a standard, neutral “limestone” color. It can be
used as-is or is ideal for accepting latex and acrylic paints and acrylic-based wall coatings (such as Sikagard® 550W, Sikagard®-515 Elastomeric, Sikagard®-575 Aquasol).
Note: in applications where joint movement occurs, unless paint or coating is flexible and can move with SafeReseal, the paint may crack. All instructions of the coating manufacturer in regards to substrate preparation to achieve adhesion acceptable to the user must be followed.


Retrofit of old sealant joints without the need for grinding to remove all old sealant residue from substrates including:

  • EIFS
  • Precast concrete
  • CMU
  • Masonry

International Patent Pending

Watertight—the tensionless coating is installed just below the substrate surface. This ensures watertightness is achieved at the face of the joint.

Non-Invasive Anchoring—there are no hard metal-to-concrete connections in the system.

Aesthetics & Versatility— Paintable/ STPE coating in standard, neutral “limestone” color. This paintable coating can also receive acrylic-based wall coatings.

Grindless — The elimination of grinding means less noise and less tenant/occupant interruption. The absence of dust means no harmful airborne contaminates like silica, extraction equipment, or specialized respiratory personal protective equipment.

Conforms to Substrate Irregularities — Small sealant joints for which this product is intended are typically “low” moving joints. With the capability of movement in excess of 100% (+/- 50% ), this allows for any additional product movement to be allocated for joint size variation.

  • Produced by infusing a cellular foam base material with a hydrophobic acrylic impregnation, and coating the surface with a STPE paintable, precured sealant coating.
  • The external facing is factory applied to the foam at a width greater than maximum joint extension and is cured before final compression.
  • Coating application and curing takes place in a temperature and humidity-controlled factory environment. This ensures, in contrast to field applied liquid sealant and backer rod installations (‘caulk-and-backer rod‘), that no movement takes place during curing that can cause deformation or stresses in the sealant material.
  • The material is precompressed to less than the joint size for easy insertion.
  • When compressed, a bellows is created in the coating. As joint movement occurs the bellows simply folds and unfolds free of tension on the bond line, and virtually free of tensile stresses in the cured sealant material.
  • The foam provides a resilient backing to the silicone coating, making the system capable of resisting air pressure differentials caused by building climate controls as well as by wind, hurricane and tornado events.
  • Substrates must be parallel, plumb, have sufficient clear depth to receive the material specified, and be capable of resisting approx. 2.5 psi backpressure from the foam.
  • As with any construction product, the useful life of the material can be maximized with routine inspection and repair if required.
  • Clearing of surface debris and inspection will reveal any damage to the product or adjacent substrates that might affect building performance.
  • Sika 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.
  • Available for shipment internationally.
  • Prices are available from local distributors or representatives. For more information, contact EMSEAL.
  • The product range is continually being updated, and accordingly EMSEAL® reserves the right to modify or withdraw any product without prior notice.
