Silicone Sealant in Jeddah | Silicone Sealant Supplier in Jeddah

Silicone Sealant in Jeddah from Nassguard includes FS703 Fire Resistant Silicone Sealant, a low-modulus, neutral-cure product for specified linear joints in compartment walls and floors. It forms an elastic seal that accommodates suitable joint movement while supporting the fire performance of the complete installation.

Nassguard supplies FS703 silicone sealant across Jeddah, Riyadh, Dammam, Jubail and Al Khobar. Its weather resistance and flexible finish make it useful for qualifying construction details that require both joint sealing and passive fire protection.

What Is FS703 Fire Resistant Silicone Sealant?

FS703 is a neutral-cure silicone sealant designed to seal linear gaps between specified building elements. These include suitable interfaces involving masonry, rigid walls, rigid floors and flexible walls.

As a low-modulus sealant, it forms an elastic joint rather than a rigid filler. This helps it accommodate movement within the limits of the selected installation detail.

Qualifying assemblies achieve up to four hours of fire resistance. The rating depends on the substrates, joint dimensions, backing material, sealant depth and installation orientation. A four-hour result for one arrangement does not establish the same performance for every joint.

• BS EN 1366-4 — Fire Resistance of Linear Joint Seals: FS703 has been tested for linear-joint fire resistance, achieving up to four hours in qualifying assemblies.

Preparing and Sealing Fire-Resistant Joints

A dependable silicone joint seal requires correct dimensions, sound surfaces and the specified backing arrangement.

• Confirm the assessed detail: Check the substrates, orientation, joint width and required fire resistance.
• Check movement requirements: Use the appropriate movement-tested arrangement where necessary.
• Clean the joint faces: Remove dust, grease, loose particles and contamination.
• Assess primer needs: Porous or metallic surfaces may require priming.
• Install the specified backing: Maintain the required backing position and sealant depth.
• Apply continuously: Fill the intended sealing zone without leaving voids.
• Tool promptly: Form a smooth finish with proper contact against the joint faces.
• Protect during curing: Avoid disturbance and unsuitable water exposure while the seal develops.

Use appropriate protective equipment and ventilation during application.

Inspection, Maintenance and Storage

Routine inspections help confirm that fire-resistant silicone seals remain intact after installation.

• Inspect for separation, cuts or missing material along the joint.
• Recheck after building alterations or work near the seal.
• Record the joint location and installation arrangement for future maintenance.
• Repair damaged sections using the appropriate assessed detail.
• Avoid covering seals with incompatible materials that could affect their condition.
• Check expiry dates and packaging before use.
• Store away from direct sunlight and excessive heat, within the specified temperature range.
