      Product Description

      POLYBIT® POLYSEAL PS+ is a two component non slumping, chemically curing sealant for wide joints. It is based on a liquid polysulphide polymer which when mixed with the hardener, cures to form a tough, flexible and non staining rubber like seal. POLYSEAL PS+ is specifically designed to be used as a watertight seal for overhead moderate movement joints and joints with widths greater than 30mm. POLYSEAL PS+ has excellent adhesion to concrete, stone, metals and other common building substrates. The cured sealant has good resistance to most environmental chemicals & resists deterioration on prolonged exposure to UV. The sealant has a movement accomodation factor (MAF) of ±25%. Available pack: 2.5L/KIT

      How to Use

      Surface Preparation and priming

      The joint surface must be clean, dry and free from oil, loose particles, cement laitance and other contaminants which may affect the adhesion.The compressible joint filler shall be cut back to expose a uniform joint depth.

      Primer should be applied to clean, dry surface prior to the installation of backer rod or bond breaking tape. Polyprime PS* is recommended to be applied on porous substrates. For non-porous substrates such as steel or glass, use Polyprime NP* for optimum adhesion. 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

      Back-up material

      A bond breaking backing rod (Polyrod)* shall be inserted into all movement joints to avoid a three sided adhesion. Use of a backing rod will ensure proper joint depth and at the same time facilitate the formation of an hour glass profile on the applied sealant. The backer rod will also provide resistance to sealant tooling pressure and help to attain proper wetting of the substrate when the sealant is being tooled. The backing rod being inserted into the joint shall be of a diameter which is at least 20% larger but not greater than 33% of the joint width. This will ensure that the backer rod remains in compression and in place during sealant installation. For static and joints where the depth is not sufficient for the use of the backing rod, a bond breaking tape may be applied to prevent the three side adhesion.

      Mixing and Application

      Polyseal PS+ is available in a ready to mix container with all the components packed in a single tin. The material shall be mixed thoroughly with a slow speed drill (300-400 rpm) fitted with a flat bladed paddle for 2-3 minutes till a uniform colour and consistency is achieved. DO NOT PART MIX. 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 eriodically scrapped with a scrapper to ensure that the curing agent is properly dispersed and blended in the mix. Load the sealant immediately into the barrel gun by a heavy duty follower plate. Start extruding into the joint firmly by maintaining an even pressure on the trigger off the gun. Vertical joint sealing shall commence from the bottom of the joint and continued to the top. Overhead sealing shall start from one end of the joint. Once the sealant has been installed a suitable rounded tool soaked in a soapy water solution can be used to achieve a smooth hour glass profile. Any masking tape applied should be removed immediately after the sealant is installed
