SealArm PS-P

Two-Part Polysulphide Joint Sealant (Pouring Grade)

Product Description

SealArm PS-P is a two-component, polysulphide-based sealant engineered for flexibility, durability, and long-term performance in movement joints. This pourable-grade sealant is designed to effectively seal expansion, contraction, and construction joints in buildings, infrastructure, and water-retaining structures.

                                                                                                                                           Or

SealArm PS-P is two packs Polysulphide based, tough flexible durable with strong adhesive sealant and is a pourable version, basically used for movement joints in concrete and pavements

Key Applications

• Expansion joints in basements, floors, roofs, and subways
• Dynamic structural cracks
• Joints in water tanks, reservoirs, dams, and canals
• High-traffic areas such as bridges, roads, and parking lots
• Ceilings with running expansion joints

Top Features & Benefits

• Self-Leveling Pour Grade – Easy to apply, ensures uniform joint fill
• UV & Weather Resistant – Withstands harsh outdoor conditions
• Fuel & Flame Resistant – As per BS 5212:1990 Type FB
• Excellent Adhesion – Bonds securely to most substrates
• Superior Chemical Resistance – Handles exposure to alkalis, dilute acids, fuels & solvents
• Wide Temperature Tolerance – Performs from -40°C to +80°C
• Long Shelf Life – 12 months from date of manufacture

Why Choose SealArm PS-P?

POSITIVE:

• Professionally trusted by engineers & builders
• Durable for decades when applied correctly
• Safe when used with proper protection

NEGATIVE:

• Not suitable for applications without proper joint preparation
• Should not be used without primer on porous surfaces
• Poor results if exposed to third-surface adhesion – always use bond breaker

Application Instructions

1. Surface Preparation – Clean, dry, and free from laitance

2. Priming – Apply SealArm PS-P Primer to porous surfaces

3. Bond Breaker & Masking Tape – Ensure neat finish & correct bonding

4. Mixing & Pouring – Mix for 8–10 mins, then pour directly into joints

5. Tooling & Clean-Up – Top-up if necessary and remove tape after application

1: Surface Preparation: The surface should be clean, dry and free from Laitance and loose particles. Correct joint design should be followed. To use economic quantity of SealArm PS-P the Width: Depth ratio should be 2:1
Back Up Materials: Insert compressible polyethylene, polyurethane, themocolfoam neoprene, polyethylene butyl rods as back-up material to control depth of sealant in the joint and to provide support for tooling of the sealant2: Priming: Apply one coat of SealArm PS-P primer on porous surface with dry brush. Please ensure the primer should not apply on Bond Breaker. Primer to be applied only on both side of concrete surface. Allow the primer to dry for one hour and then apply the sealant as soon as possible and certainly within 8 Hours.3: Bond Breaker: Fix bond breaker tape such as self adhesive polyethylene tape on back-up material to avoid adhesion of sealant to the third surface.
4: Masking Tape: Apply masking tape such as self-adhesive polyethylene, cellophane or cloth tape on both edges of the joint. It is used to improve the neatness of the finished seal by protecting the face edges of the joint. It may be removed immediately after Tooling of the sealant.5: Mixing: Both parts of Polysulphide are Preweighed materials; by using paddle type mixer both the parts to be mixed till a smooth uniform Consistency mix is obtained. Mixing time normally is around 8 to 10 minutes.
