Areas of application
BORNIT® Cold Joint Sealant is used for sealing vertical or inclined joints in concrete traffic areas and cut asphalt surfaces. BORNIT® Cold Joint Sealant reliably seals joints against the penetration of water pollutants into the ground. In particular, it is suitable for sealing joints in road, bridge and tunnel construction as well as in the basement and base area.
BORNIT® Cold Joint Sealant is suitable for sealing floor or ground-level joints between concrete elements as well as concrete components and asphalt surfaces subject mechanical stresses (vehicle and pedestrian traffic), chemical stresses from de-icing salts and temperature-dependent movements of the components. Upon use in concrete surfaces, BORNIT® Cold Joint Sealant can also be subjected to chemical stresses from fuels.
Horizontal joints with an inclination of less than 3 % should be sealed with the self-levelling BORNIT® Cold Sealing Compound. The joint sealant must not be used for joints, which are permanently under the surface of liquids (e.g. in swimming pools, clarification tanks) or are exposed to strongly oxidising acids and bases, as well as for joints in facilities for storing, filling and transhipping of water pollutants (called LAU plants) and for glass sealing.

Type and properties
BORNIT® Cold Joint Sealant is an elastic, stable, two-component, polysulphide-based joint sealant for joints with an elasticity of up to 35 % of the joint width. In the hardened state, BORNIT® Cold Joint Sealant results in elastic joint sealing with very good weather and ageing resistance and high mechanical strength. BORNIT® Cold Joint Sealant corresponds to DIN EN 14188-2.

Advantages
  • very flexible
  • waterproof and UV-resistant
  • universally applicable
  • less equipment, material and labor required for processing

Surface
The joint flanks must be clean, dry, firm, and free of grease and dust. Asphalt flanks must be freshly cut. The joint widths must be matched to the expected movement

Processing
The bonding surfaces of the joints to be sealed must be cleaned from dirt, dust, greases, oils, bitumen and loose particles. For the correct depth, and in order to avoid adhesion on three surfaces, the joints are clamped and backfilled with foamed PE-based round material (closed-cell round PE profile) (BORNIT® Round Cord). Should this not be possible, the joint base must be covered with a separating material (PE sheet, silicone paper or the like).
Subsequently, for concrete joints, thoroughly mixed BORNIT® Concrete Primer must be uniformly applied to the dry fusion faces. After a flash-off time of 0.5-2 hours (depending on the temperature, the primer should not be completely dry), BORNIT® Cold Joint Sealant can be inserted. The BORNIT® Concrete Primer should not be completely dried off. If more than 24 hours should have passed, the primer layer must be roughened and new primer applied.

Asphalt joints must be primed with BORNIT® Asphalt Primer. The asphalt joints must be freshly cut, since adhesion problems would otherwise result. The components A and B are mixed thoroughly and the primer is uniformly applied with a brush. After a flash-off time of 2 to 6 hours (component temperature > +25 °C approx. 2 hours, < +10 °C approx. 6 hours), the sealant can be introduced. The asphalt primer should have dried as far as possible. It must be observed that no moisture film has formed on the primer surface due to undercutting of the dew point. For BORNIT® Cold Joint Sealant, the components A and B are both contained in one container in layers and not packaged separately. First mix the components (layers) with a suitable tool (slow-speed drill with mixing paddle stirrer), until there are no colour streaks anymore. Now insert the joint sealant into the joint with suitable tools (e.g. manual or compressed air guns) and smooth it with a spatula, smoothing stick or the like within the processing time. Prior to mixing, the temperature of the sealant should be min. +10 °C. The component temperature must not be below +5 °C and not above +40 °C. Until reaching the full load-bearing capacity, a thorough hardening time of min. 48 hours at +20 °C ground and materials temperature must be complied with.
