POLYSULPHIDE BASED SEALANT
Hind Sealant PS is two-component system. After mixing two components, the mixed material provides a strong
and highly elastic sealant through cross-linking process. It is available in two grades. Gun grade or non-sag-type
is applied for vertical and inclined expansion /contraction joints & pour Grade type for horizontal joints.
Conforming to IS 12118 – 1987 & BS – 4254 – 1983. Also available as per BS 5212, Part 2
Hind Sealant PS is used both horizontal & vertical expansion contraction joints in all type of building and civil
engineering construction such as:
· Retaining wall
· Precast Concrete Element.
· Underpasses and Tunnels
· High and Low Rise building and wherever a permanently flexible seal is required.
· Hind Sealant-PS pouring grade is designed specially for runways, subways, rigid pavements joints &
· Economical and Easy to use
· Excellent adhesion to many substrate.
· Non-sag in vertical and overhead joints with Gun grade
· Easy to pour on horizontal joints with Pouring grade
· Permanently elastic
· Good chemical resistance.
Surface Preparation: All surfaces must be clean, dry and free from loose particles. Correct joint depth can be
determined by inserting compressible board tightly into the joint. Protect surface with a masking tape.
Priming : Hind Sealant PS primer is recommended for the surface namely concrete, brickwork, asbestos,
cement, gypsum board, stone, glass, timber, rigid PVC, anodized aluminum, ceramics etc. Primer is not required
for Epoxy and polyester surfaces.
Mixing : Both components are pre-measured. Use a suitable instrument for mixing. Mix for 8 to 10 minutes or
until smooth and homogeneous material results. Using a pressure gun install the sealant into the joint without
trapping air. Tool-off with a spatula to lightly concave profile. Remove masking tape.
Joint Design: Minimum joint depth = 8 mm
Maximum joint width = 50 mm
Width to depth ratio for joints upto 10mm wide = 1:1
Width to depth ratio for joints from 10mm to 50mm = 2:1
