Sika Polysulphide Gun Grade
Two-component, non-sag polysulphide sealant for vertical and overhead movement joints
Product Overview
Sika Polysulphide Gun Grade is a two-component, cold-applied polysulphide joint sealant formulated with non-sag rheology for vertical, sloped and overhead joints. Once Part A and Part B are mixed and gunned into the joint, it cures to a permanently elastic, watertight seal that accommodates structural movement while resisting UV, weathering, water, fuels, oils and solvents. It is widely specified for expansion joints in precast concrete, water-retaining structures, buildings, bridges, tunnels and pavements where durability and chemical resistance matter. Because it holds its shape on walls and soffits without slumping, it is the preferred grade for non-horizontal joints. Engineers, applicators and infrastructure contractors rely on its proven standards compliance. Space Arc Engineering, an authorized Sika distributor in India, supplies this sealant with batch-matched sets and on-site technical support.
Features & Benefits
- Non-sag consistency holds firmly in vertical and overhead joints without slumping
- Accommodates up to plus or minus 25% joint movement for long-term durability
- Resists water, fuels, oils and solvents, suiting industrial and trafficked joints
- Stays permanently elastic and watertight after cure for dependable sealing
- Bonds strongly to concrete, metal and most construction materials
- Meets recognised standards including BS 4254, IRC:57 and IS:12118 for specified work
Technical Highlights
| Coverage | Yield depends on joint width and depth; consumption follows the recommended 2:1 width-to-depth ratio (refer to TDS for joint tables). |
| Strength | Provides a tough, permanently elastic seal accommodating plus or minus 25% movement on properly designed joints. |
| Performance | Skins in about 6 hours and fully cures in around 7 days at +30°C; pot life exceeds 90 minutes at 30°C for a 500 g mix. |
| Application Conditions | Apply between +5°C and +45°C; suits joints 5-50 mm wide with minimum depths of 5 mm (non-porous), 10 mm (porous) and 20 mm (trafficked). |
| Packaging | Supplied as 4 kg sets (Part A 3.68 kg + Part B 0.32 kg), two sets per box; mixing ratio 92:8 by weight. |

Frequently Asked Questions
What is Sika Polysulphide Gun Grade used for?
It is a two-component polysulphide sealant for expansion and movement joints in concrete and between dissimilar materials, used in buildings, water structures, bridges, tunnels and pavements, especially in vertical and overhead joints.
How much movement can the sealant accommodate?
It accommodates up to plus or minus 25% joint movement when the joint is correctly designed, typically at a 2:1 width-to-depth ratio.
What is the mixing ratio and pot life?
Part A and Part B are mixed at 92:8 by weight, and the pot life is greater than 90 minutes at 30°C for a 500 g mix. Confirm against the current TDS.
Is it resistant to fuels and chemicals?
Yes, after curing it resists water, fuels, oils and solvents, which makes it suitable for industrial and trafficked joints. It also resists UV and weathering.
