Two Component Polysulphide Sealant
ELASTOSEAL PS is a two part, high performance Polysulphide joint sealant. It is specifically designed for sealing movement joints in buildings and civil engineering structures especially where the service conditions would be harsh for most common sealants.
ELASTOSEAL PS is produced in two grades – PG (pouring grade) self-leveling for horizontal joints and GG (thixotropic gun grade) for vertical joint applications.
Highly resilient with excellent recovery characteristics
Maintains flexibility over time
Excellent resistance to fatigue and deterioration due to weathering, UV light and airborne pollutants
Accommodates continuous and cyclic movements
Excellent adhesion to most common substrates
Store the product in dry closed place with temperature between 10 to 35ºC. Storage above this temperature may reduce shelf life. The product maintains its stability for 12 months.

Apply SEALPRIME to both the sides of the porous joint faces prior to installation of backer rod or bond breaking tape, by brushing in a thin uniform coat. Avoid applying too much primer as it may act as bond breaker.
For non-porous substrate such as steel or glass, use SEALPRIME NP for optimum adhesion. The primer shall be applied by brush in a thin coat and shall be allowed to become tack-free prior to application of 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 edges of the groove before applying the primer.
Mix and use one complete unit at a time. ELASTOSEAL PS is supplied as base / hardener combined unit. Pour the hardener (Component B) into the base (Component A) pail and mix thoroughly with a slow speed drill (300-500 rpm) fitted with a flat bladed paddle for 8-10 minutes till a uniform color and consistency is achieved.
Scrape down the sides as much as possible using a pallet knife and avoid lifting the mixing paddle out of material to minimize entrapment of air.
Apply ELASTOSEAL PS immediately after mixing by pouring directly into the joint (in case of pouring Grade) or by using a professional caulking gun with consistent, positive pressure to force the sealant into the joint (in case of Gun grade). Fill the joints from the bottom up to the exterior surface, avoiding bridging which may form air voids. Use the sealant tool soaked in soapy water to compact the sealant into the joints and to achieve a smooth concave polished surface.
Any masking tape which has been applied should be removed before the sealant cures.
ELASTOSEAL PS may be applied to joints between 6 and 40 mm wide. Joints expected to experience cyclic movements should have a width depth ratio 2:1 for butt joints and 1:1 for floor, static and lap joints and should be designed such that the total movement does not exceed the 25% MAF. The joints depth shall not exceed the width.
Minimum sealant depth recommended:
To control joint depth, use CORDOFLEX a closed cell polyethylene backer rod. The backer rod shall be of a diameter which is at least 20% larger but not greater than 33% of the joint width to ensure that it remains in compression. If the joint depth does not allow backer rod, use polyethylene bond breaker tape to prevent three sided adhesion. Do not prime or puncture the backer rod.
Clean tool with SOLVENTE 10 promptly before material hardens. Cured material must be mechanically removed.
The joint surface must be clean, dry and free from loose and flaky material, efflorescence, laitance, curing compound, dirt, oil, grease, any old coatings.
Surface defects at edges and corners of the joints should be repaired using appropriate Colmef Repair Products and allowed to cure for the specified duration as recommended in the respective technical data sheet.
Avoid contact with skin & 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.
