Heavy Duty Epoxy Urethane Joint Sealant
ELASTOSEAL EPU is a two component self-leveling epoxy modified polyurethane joint sealant. It can be poured directly into horizontal joints in order to form a tough resilient seal containing a limited degree of flexibility.
ELASTOSEAL EPU can accommodate small amount of movement in expansion and contraction but can take high compressive stresses.
4 Liter kit (Part A and Part B).
Keep the product in dry and covered shed. Exposure to extreme temperature and humidity results in the deterioration of the product’s efficiency and reduces its shelf life.

The joint surface must be clean, dry and free from oil, loose particles, cement laitance and other contaminants which may affect the adhesion. A thorough wire brushing, grinding, sand blasting or solvent cleaning may be required to expose a clean and sound substrate. The compressible joint filler shall be cut back to expose a uniform joint depth.
SEAL PRIME should be applied to clean, dry surface prior to the installation of backer rod or bond breaking tape. The primer shall be applied by a brush in a thin coat application and shall be allowed to become tack free prior to the application of the sealant. The joint edges shall be re-primed if the sealant installation is not carried out within 3 hours of application of the primer. For obtaining a clean and neat finish, masking tape shall be applied on both the edges of the groove before applying the primer.
ELASTOSEAL EPU is supplied in pre-weighed two part packs, which requires on site mixing. Pour the hardener (PART B) into the base (Part A) pail and mix thoroughly with a slow speed drill (300-400 rpm) fitted to a flat bladed paddle for 5 minutes till a uniform colour and consistency is achieved.
Since the base and the curing agent ratio controls the ultimate physical properties like adhesion, durability and strength, one complete kit has to be mixed at a time. The side and base of the container shall be periodically scrapped with a scraper to ensure that the curing agent is properly dispersed and blended in the mix.
Pour the mixed material directly into the joint from the pail. Initially fill 2/3 of the sealant, tool it properly allowing it to fill all the irregular areas inside the joint. The tooling will also allow entrapped air to escape. Then pour the balance 1/3 material and further tool it to get a smooth surface finish. The material should be used completely within the specified pot life. Once the sealant has been installed a suitable rounded tool soaked in soapy water can be used to achieve an hour glass profile. Any masking tape applied should then be removed immediately after the sealant is installed.
Clean the used tools with SOLVENTE 10 immediately after completing the job and before the product dries.

Avoid contact with skin or eyes. During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment if necessary.
In case of contact with skin, rinse with water and again wash thoroughly with soap and water. In case of contact with eyes, rinse with plenty of water and seek medical advice accordingly.
If ingested, obtain medical attention immediately. Do not induce vomiting.
