Product selection and use guide
Sealant Bostik Seal N Flex One Plus Grey 600 ml is a sealant for joint details; its chemistry must be matched to the substrate before use.
How to choose
Check cure type, substrate compatibility, joint movement, width and depth. Do not select by colour or the silicone name alone.
Applications to consider
Consider building or fabrication joints listed in the exact type data; check primer and backing rod requirements.
Use limitations
Sealant is not the main insulation layer or a structural adhesive unless supported by use data. Hi-temp or weatherproof names do not prove every service condition; firestop needs a tested system.
Pre-order checklist
- Send materials on both sides, joint dimensions, total length and exposure conditions.
- Confirm cure type, colour, pack size, primer and safety instructions.
Frequently asked questions
Can neutral and acetoxy types replace each other?
Not automatically. Check substrate compatibility and exact type data, particularly for materials sensitive to cure chemistry.
How is sealant quantity calculated?
Use joint cross-section, total length, backing detail and pack contents; confirm allowances with the applicator.
Can ordinary sealant be used for firestop?
Do not assume so. The type and system detail need test evidence for that application.
