BoPin 635 Natural Stone Silicone Sealant

Product Description

Specialized non-staining neutral silicone specifically developed for use with natural stone. Unique formula prevents edge discoloration and staining on sensitive porous surfaces while providing superior adhesion and flexibility.

Colour

  • True Non-Staining Formula: No edge discoloration or migration into porous materials
  • Superior Natural Stone Adhesion: Excellent bonding without primer on marble, granite, and limestone
  • Advanced Mold Resistance: Prevents fungal growth on sealed joints in wet areas
  • High Movement Capability (±25%): Accommodates thermal and structural movement
  • UV and Weather Stability: Maintains appearance and properties despite sun exposure
  • Quick Skin Formation: Reduces risk of surface contamination in dusty environments

Application

  • Sealing joints in marble, granite, and limestone installations
  • Kitchen countertop perimeter sealing
  • Bathroom vanity top edge sealing
  • Stone facade and cladding joints
  • Interior and exterior stone tiling
  • Natural stone window sills and thresholds

Applicable Materials

  • All types of natural stone (marble, granite, limestone, travertine)
  • Engineered stone and quartz surfaces
  • Ceramic and porcelain tiles
  • Glass and glazed surfaces
  • Most metals and coated metals
  • Concrete and masonry surfaces

Color

Black, Brown, Clear, Customized, Grey, White

Surface Preparation:

  • Ensure stone surfaces are completely clean, dry and dust-free
  • Clean joints with alcohol-based cleaner without additives
  • Allow surface to dry completely before application
  • For polished stone, protect adjacent areas with masking tape

 

Application Method:

  • Cut cartridge tip at 45° angle for desired bead size
  • Apply with even pressure using professional sealant gun
  • Fill joint completely without air pockets
  • Tool within 10 minutes using dry tooling or minimal tooling solution
  • Remove masking tape immediately after tooling

 

Joint Design:

  • For countertop joints: Ensure minimum 3mm gap for thermal expansion
  • For areas with significant temperature variations, use wider joints
  • Use backing rod or bond breaker tape to prevent three-sided adhesion
  • Minimum joint width: 6mm
  • Maximum joint width: 30mm
  • Optimal width-to-depth ratio: 2:1

Limitation

  • Not suitable for PE, PP, Teflon, and bituminous surfaces
  • Not recommended for structural glazing or underwater applications
  • Cannot be painted (use BoPin MS-240 for paintable applications)
  • Not suitable for joints subject to heavy traffic or abrasion
  • Not for continuous water immersion applications

Application

  • For perfect color matching with specific stone, request custom color options for larger projects
  • Always perform test application on inconspicuous area of actual stone being used
  • For best results on polished stone, apply masking tape before sealing and remove immediately after tooling
  • In wet area installations, ensure joint is fully cured before water exposure
  • For outdoor stone applications, slightly wider joints are recommended to accommodate thermal movement
