CONSTRUCTION JOINT SOLUTIONS
Joint Sealing &
Weatherproofing
Find a starting point for facade weatherseals and stone or concrete joints. Explore S300 and S500, then discuss the materials, joint design and conditions of your project.
For overseas distributors, facade contractors & installers

START WITH THE JOINT
Different surfaces.
Different sealing needs.
Exterior exposure and stone sensitivity call for different selection questions. Start with the application, then review the complete material combination.
Facade and exterior joints
Discuss exposed joints between facade elements, external curtain-wall weatherseals and perimeter connections. Share the glass, metal finish, coating or panel surface on each side.
Stone and concrete joints
Discuss non-structural joints between stone finish elements, concrete and adjoining surfaces. Stone type, treatment and staining sensitivity are central to the selection.
FOR FACADE & EXTERIOR JOINTS
S300 Weatherproof
Facade Silicone Sealant
Discuss S300 for non-structural weathersealing around facade elements. Review the joint movement, weather exposure and material combination before selecting a product option.
- Application focus
- Facade joints and exterior weatherseals
- Joint role
- Non-structural sealing
- Selection starts with
- Substrates, finishes, movement and exposure
- Supply options
- Share your colour and packaging preferences
Curtain-wall weathersealing and structural glass bonding have different roles. Match the sealant to the specified joint and confirmed product data.
FOR STONE & CONCRETE CONNECTIONS
S500 Stone & Concrete
Silicone Sealant
Discuss S500 for non-structural joints involving stone finishes and concrete. Describe the actual stone, treatment and adjacent materials so adhesion and appearance requirements can be reviewed.
- Application focus
- Stone and concrete connection joints
- Stone selection
- Stone type, finish and surface treatment
- Appearance review
- Adhesion and staining checks on actual samples
- Supply options
- Confirm colour, capacity and packing for your order
Natural stone needs a material-specific assessment. Review representative samples before approving the sealant and joint appearance.

APPLICATION TO PRODUCT DISCUSSION
Match the product
to the connection.
A product name is the starting point. The actual surfaces and joint requirements guide the final selection.

| Facade / exterior weatherseal | S300 Facade Silicone↗ | Panel or glass, metal finish, movement, joint geometry and exposure. |
| Stone / concrete connection joint | S500 Stone & Concrete Silicone↗ | Stone type and treatment, adjacent materials, adhesion and staining requirements. |
| Distributor construction-sealant range | S300 + S500 enquiry↗ | Customer applications, preferred colours, packaging, destination and quantities. |
Review the complete joint assembly.
Include coatings, backing materials, primers, gaskets and adjacent sealants in the material review. Share the joint drawing and any adhesion, staining or project-document requirements.

- 01
Materials & finishes
Identify both joint faces, the stone type, coatings and adjacent materials.
- 02
Movement & joint
Share dimensions, the movement requirement and a joint photo or drawing.
- 03
Exposure & appearance
Describe indoor or exterior conditions, staining sensitivity and preferred colour.
- 04
Market & order
List products, packaging preferences, destination and expected quantities.
JOINT SEALING QUESTIONS
Before you enquire.
How should I choose between S300 and S500?+
Start with the application. Discuss S300 for facade and exterior weathersealing, and S500 for joints involving stone and concrete. Share the materials, finishes, movement and exposure so the actual product option can be reviewed.
Can a facade weatherseal secure curtain-wall glass?+
Structural glazing requires a separately specified adhesive and system assessment. This page covers non-structural joint sealing; glass attachment and cladding support follow the project design.
What should I check when sealing natural stone?+
Identify the stone, surface treatment and adjacent materials. Assess adhesion and staining behaviour on representative samples before approval. A stone-related product name does not establish compatibility with every stone.
Can I enquire about both products for distribution?+
Yes. Share your customer applications, market, preferred colours, packaging and quantity for each product. Supply options, minimum orders and distributor cooperation terms are confirmed for the specific enquiry.
