Fire Resistant Sealant in Saudi | Concrete Sealant Supplier in KSA

Fire Resistant Sealant in Saudi from Nassguard includes FS704 Fire Resistant Hybrid Sealant, an elastic joint-sealing product for specified gaps in compartment walls and floors. It combines tested fire performance with flexibility, smoke sealing and acoustic benefits.

Nassguard supplies FS704 hybrid sealant across Riyadh, Dammam, Jubail, Jeddah and Al Khobar. Its formulation is free from silicone, isocyanates and phthalates, making it a distinct option for contractors seeking a hybrid sealant for suitable fire-rated construction details.

What Is FS704 Fire Resistant Hybrid Sealant?

FS704 is a hybrid-polymer sealant that cures through reaction with moisture in the air. It forms a soft, elastic seal with resistance to light, ageing and weathering.

Its primary fire-stopping application is linear-joint sealing between specified building elements. Suitable combinations include concrete, steel, timber and drywall, subject to the assessed installation arrangement.

Qualifying joints achieve up to two hours of fire resistance. The substrate, backing, sealant depth, joint width and installation orientation determine the actual rating. Its 25% movement capability applies during normal building use; it does not establish the same movement performance during a fire.

Key Features of FS704 Hybrid Sealant

FS704 fire-resistant sealant brings together elastic sealing and tested performance for suitable construction joints.

• Hybrid-polymer formulation: Provides a flexible alternative to conventional acrylic and silicone joint sealants.
• Tested fire resistance: Achieves up to 120 minutes in qualifying linear-joint arrangements.
• 25% movement capability: Accommodates specified movement under normal, non-fire conditions.
• Silicone-free composition: Also free from isocyanates and phthalates.
• Smoke-sealing function: Helps close leakage paths through correctly installed joints.
• Acoustic performance: Tested assemblies achieve sound insulation of up to 66dB.
• Air-sealing performance: Tested at air pressures up to 600Pa.
• Paintable finish: Can be painted where required, after checking coating compatibility.

Applications of Fire Resistant Sealant in Saudi

FS704 supports linear-joint sealing where the proposed construction matches an assessed detail.

• Commercial buildings in Riyadh: Seal qualifying joints between concrete elements.
• Fit-out projects in Jeddah: Complete suitable drywall-to-drywall and drywall-to-concrete interfaces.
• Industrial buildings in Dammam: Seal specified steel-to-steel or steel-to-concrete joints.
• Facility upgrades in Jubail: Restore damaged construction-joint seals.
• Office developments in Al Khobar: Complete qualifying interfaces between flexible and rigid walls.
• Timber construction: Seal assessed timber-to-timber and concrete-to-timber joints.
• Healthcare and education buildings: Support compartmentation at suitable construction interfaces.
• Weather-exposed joints: Use in appropriate details where weathering resistance is required.

Select FS704 for its assessed joint-sealing applications. Service penetrations around pipes or cables require their own verified fire-stopping arrangement.

Certifications, Standards and Compliance

• BS EN 1366-4 — Linear-Joint Fire Resistance: FS704 has been tested to EN 1366-4:2021, achieving up to two hours in qualifying assemblies.
• ISO 11600 — Sealant Classification and Requirements: FS704 has a 25LM classification, with 25% movement capability under normal building-use conditions.
• VKF Recognition No. 40318: Swiss recognition covers specified FS704 joint-sealing arrangements within the conditions stated in the approval.

Preparing and Applying Hybrid Fire Seals

A dependable fire-resistant joint seal requires correct backing, seal depth and adhesion to the joint faces.

• Confirm the assessed arrangement: Check substrates, joint orientation, dimensions and required fire rating.
• Account for movement: Match the joint design to anticipated building movement.
• Prepare sound surfaces: Remove dust, grease, loose particles and contamination.
• Check primer requirements: Porous or metallic surfaces may require priming.
• Install the specified backing: Maintain the required backing type, depth and position.
• Apply a continuous bead: Fill the sealing zone evenly without concealed voids.
• Tool promptly: Form a smooth finish with proper contact against both joint faces.
• Check decorative finishes: Confirm paint compatibility before coating the completed seal.

Use suitable protective equipment during application and protect the joint from disturbance while curing.

Inspection, Maintenance and Storage

Routine inspections help confirm that FS704 joint seals remain intact throughout the building’s use.

• Check for separation, cracking or missing material along the joint.
• Reinspect after alterations or work near the sealed interface.
• Look for movement-related damage where building elements meet.
• Repair using the appropriate assessed detail, including backing and seal depth.
• Retain installation records for maintenance reference.
• Check packaging and expiry dates before application.
• Avoid hot vehicles and direct sunlight when storing material on Saudi sites.
