Polyseal PS is a two component, low modulus, chemically curing polysulphide joint sealant, developed specifically for dynamic joints. Polyseal PS is based on a liquid polysulphide polymer which when mixed with the hardener, cures to form a tough rubber-like seal. Polyseal PS exhibits excellent adhesion to most surfaces and has good resistance to many chemicals and weather conditions. Polyseal PS is available in both gun grade and pouring grade. The gun grade is suitable for vertical or horizontal applications and is available in a ready to mix, two and a half litre tin containing the base and curing agent in correct proportions. The pouring grade is suitable for horizontal applications and is available in a four litre pack with base and curing agent in separate tins.

AREAS OF APPLICATION
JOINT DESIGN GEOMETRY
The width of the joint should be a minimum of 4 times the anticipated movement. Joints with cyclic movement should have a width to depth ratio of 2:1. Minimum depth of the sealant should be maintained as recommended below :
10mm for all porous surfaces. 20mm for joints exposed to traffic & hydrostatic pressure. 5mm for impervious surfaces such as metal, glass, etc.

Note : The product’s design and performance, its intended use, installation and final confirmation and approval for use, must be provided by the project’s Design Engineer and Project Manager.
PRIMING Primer should be applied to a clean, dry surface prior to installation of backer rod and/or bond breaker tape. Polyseal Primer is recommended for most common substrates like concrete, tiles, etc. For non-porous substrates like glass & steel, special primer can be applied to achieve optimum adhesion. Where a particularly neat finish is required, apply masking tape on both sides of the joint before priming and remove immediately once the sealant application is complete.
BACKING MATERIAL Closed cell polyethylene backer rod should be used to control the depth of the joint sealant to the recommended thickness. Where joint design or depth of joint will not permit the use of backing rod, use a bond breaker tape.
JOINT PREPARATION The joint surface must be clean, dry and free from oils, loose mortar, laitance, release agents and other contaminants. A thorough wire brushing, grinding, sand blasting or solvent cleaning may be required to expose a clean and sound surface.

PACKAGING
2.5 litre Gun Grade Part A & B in the same pail
4.0 litre Pouring Grade Part A = 4.0 litre pail Part B = 500 ml pail
Note : Calculation based on theoretical coverage. Actual material consumption at site will vary depending on the condition of the joints and wastage etc.
Supplied 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.Note : Mix one full kit at a time to avoid improper mix ratio. DO NOT PART MIX.
Supplied in a pre-weighed two parts pack 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 1-2 minutes till a uniform colour and consistency is achieved.Note : Mix one full kit at a time to avoid improper mix ratio. DO NOT PART MIX.
Once the sealant has been applied, a suitable rounded tool soaked in soapy water can be used to achieve a smooth finish. Any masking tape applied should be removed before the sealant skins over.
Remove all excess sealant with a scraper. Any spillage can be cleaned using a solvent like Xylol. Clean all tools and sealant gun using a similar solvent immediately after the tooling is finished.
