Packaging Type: Hard tube, Sausage pack/cartridge
Shelf Life: 12 months from production date (in sealed original container)
Storage Conditions: Store in cool, dry place below 27°C

Step 1: Surface Preparation (CRITICAL for stone applications)

Ensure stone surfaces are completely clean, dry, and free from dust, dirt, oil, grease, wax, sealers, and loose particles
For porous stones (marble, limestone, travertine), ensure surfaces are sufficiently dry – moisture can cause adhesion failure
Remove any previous sealants or coatings
IMPORTANT: Do NOT use oily or solvent-based cleaners that may contaminate the stone
Use only water or approved stone cleaners, then allow to dry completely

Step 2: Pre-Application Testing (HIGHLY RECOMMENDED)

Always conduct a small test application on an inconspicuous area of the actual stone
Check for staining, discoloration, or adhesion issues after 24-48 hours
Test is especially important for porous or light-colored stones
Verify compatibility with any stone sealers or treatments

Step 3: Joint Design

Use appropriate backer rod or bond breaker tape for joints deeper than 12mm
Recommended joint width-to-depth ratio: 2:1 for optimal performance
Ensure three-sided adhesion is avoided to prevent joint failure
For stone-to-stone joints, maintain consistent joint width

Step 4: Application

Cut the cartridge nozzle at a 45° angle to desired bead size
Load cartridge into a standard caulking gun
Apply sealant evenly and continuously into the joint
Ensure complete joint filling without air pockets or gaps
Work in small sections to maintain quality

Step 5: Tooling & Finishing

Tool the sealant surface within 10-15 minutes of application before skin formation
Use a spatula or smoothing tool moistened with soapy water (DO NOT use solvents)
Immediately clean any excess sealant from stone surfaces before it cures
Remove masking tape immediately after tooling

Step 6: Curing & Protection

Allow adequate curing time: typically 7-21 days for full cure depending on joint depth and conditions
Protect joints from rain, moisture, and contamination during initial 24-48 hours
Avoid stress, traffic, or movement during cure period
Keep work area clean to prevent contamination of stone

Tips

Size Selection Guide:

590ml: Best for large stone projects, commercial installations, professional contractors
300ml: Ideal for small residential projects, repairs, maintenance work, DIY applications

CRITICAL – Stone-Specific Guidelines:

Pre-Installation:

ALWAYS test on actual stone samples first – different stone types react differently
For white marble, Carrara, and other light-colored porous stones, testing is MANDATORY
Consult stone supplier about any pre-applied sealers or treatments
Check moisture content of stone before application (especially important for natural stone)

Stone Types – Special Considerations:

Marble & Limestone (porous): Extra care needed, must be completely dry, test for staining
Granite (dense): Generally good adhesion, minimal staining risk
Travertine (very porous): May require special surface preparation
Sandstone (porous): Test thoroughly, may show darker appearance around joints
Polished surfaces: Clean thoroughly to remove polishing compounds
Honed/Flamed surfaces: May absorb sealant differently than polished

For Best Results:

Clean excess sealant from stone IMMEDIATELY before it skins over
Use masking tape to protect stone surfaces and ensure clean lines
Work in moderate temperatures (15-25°C ideal) for best flow and cure
Avoid application in direct sunlight on dark stone (surface too hot)
For large projects, maintain consistent application technique across all joints

Color Matching:

Clear/Transparent: Best for translucent stones, colored glass
White: For white marble, limestone, light-colored stones
Stone Gray: For gray granite, concrete, metal panels
Beige: For beige marble, travertine, sandstone
Custom colors available for large projects (consult factory)

Swift Series Value Proposition:

Professional-grade stone sealant at competitive pricing
Same non-staining performance as premium brands
Ideal for contractors seeking quality without premium pricing
Excellent for large-scale stone projects where cost efficiency matters

Quality Assurance:

Inspect all joints for complete fill and proper tooling
Check for any sealant residue on stone surfaces – clean immediately
Monitor first few installations closely for any staining issues
Document all testing and installation procedures

Maintenance:

Advise owners that silicone joints cannot be painted or stained
Joint color may vary slightly from stone color
Regular cleaning with pH-neutral cleaners is recommended
Inspect joints annually for any degradation or damage

Storage & Handling:

Store cartridges upright in cool, dry conditions
Rotate stock using FIFO principle
Once opened, use within one month for optimal performance
Protect from freezing and excessive heat

Environmental Considerations:

Ensure adequate ventilation during application and cure
Dispose of empty cartridges according to local regulations
Clean tools with mineral spirits; cured sealant removes mechanically
