Sikaflex-PRO-3 IN
Professional Polyurethane Floor Joint Sealant for Industrial Applications
Authorized Project Distributor — Sika India | Space Arc Engineering, Ghaziabad
Product Overview
Sikaflex-PRO-3 IN is a one-component, moisture-curing, high-performance polyurethane floor joint sealant specifically engineered for the demanding conditions of industrial concrete floor joints. Concrete floor slabs are saw-cut after casting to create contraction joints at regular intervals, preventing uncontrolled cracking. These saw-cut joints must be sealed to prevent ingress of water, chemicals, and incompressible debris (grit, stones) that would cause joint lip spalling under forklift and heavy vehicle wheel loads. Sikaflex-PRO-3 IN provides a tough, semi-rigid seal that resists forklift wheel impact, chemical splash from industrial processes, and the compressive forces from thermal expansion of adjacent slab panels. Space Arc Engineering distributes Sikaflex-PRO-3 IN for industrial warehouse, logistics park, and factory floor joint sealing projects across Delhi NCR and UP.
Applications
- Saw-cut contraction joint sealing in industrial concrete floors
- Construction joint sealing in warehouse and logistics facility floors
- Forklift traffic areas requiring impact and chemical resistant joint sealant
- Cold store floor joints requiring low temperature flexibility
- Food processing and pharmaceutical floor joint sealing
- Loading bay and dock leveller surround joint sealing
Key Advantages

- Chemical resistance to oils, hydraulic fluids, and dilute chemicals
- Remains flexible and sealed at low temperatures in cold stores
- Easy cartridge application — one-component, no mixing
- Rapid surface skin for fast return to traffic
- Adhesion to concrete without primer in most applications

Frequently Asked Questions
Why use a specific floor joint sealant instead of standard Sikaflex-Construction Plus?
Floor joint sealants like Sikaflex-PRO-3 IN are formulated with higher hardness and stiffness than facade sealants to resist the compressive and shear loads from forklift and vehicle wheels passing over sealed joints. Standard construction sealants are too soft for floor joint use and would be damaged by wheel traffic.
How deep should the saw-cut joint be filled when using Sikaflex-PRO-3 IN?
The joint should be filled to approximately 5–10 mm below the floor surface level, with the sealant depth equal to the joint width (1:1 aspect ratio). Insert a bond-breaker rod at the base of the joint to prevent three-sided adhesion and ensure proper sealant movement performance.
Can Sikaflex-PRO-3 IN be used in food processing plants?
Yes. Sikaflex-PRO-3 IN is suitable for use in food processing plant floor joints once fully cured. For facilities with the most stringent hygiene requirements, confirm with Space Arc Engineering that the specific product variant and cure state meet your regulatory or certification requirements.
