Frequently Asked Questions

1

Why choose ARBOSEAL Pro® Arbokol 682 Balustrade Sealant for glass balustrade installation?
Arbokol 682 is specifically formulated for glass balustrade applications and tested to the requirements of BS 6180:1999 — the British Standard governing the installation of glass in structural balustrade systems. Its two-part epoxy polysulphide chemistry provides a Shore A hardness of 95, creating an extremely stiff, load-bearing seal capable of structurally supporting glass panels in their channels. The two available grades — Gun Grade and Pouring Grade — cover the full range of installation methods used in glass balustrade construction.

2

What are the key benefits of ARBOSEAL Pro® Arbokol 682 Balustrade Sealant?
Arbokol 682 provides a structurally robust seal with proven adhesion to glass, concrete, stone, and metal substrates. With a Shore A hardness of 95, Very Good UV resistance, and a 20-year service life, it is designed to maintain performance in both internal and sheltered external balustrade environments. The Gun Grade and Pouring Grade options give specifiers and installers the flexibility to select the most appropriate application method for each individual project. External applications require Arbosil 1096 S silicone capping for full weather protection.

3

What is the ARBOSEAL Pro® range?
The ARBOSEAL Pro® range is a comprehensive portfolio of professional-grade sealants manufactured by Adshead Ratcliffe under the ARBO® brand. The range covers silicone, modified polymer, polyurethane, polysulphide, epoxy, acrylic, butyl, and oil-based sealant technologies, providing a complete solution for sealing, bonding, and jointing across all types of construction projects — from glazing and cladding to flooring, facades, and secure environments.
 

4

Which ARBOSEAL Pro® sealant is right for my application?
Product selection depends on the substrate type, joint movement, environmental exposure, and performance requirements. Neutral cure silicones (e.g. Arbosil LMS, Arbosil 1096 S) suit glazing and perimeter sealing. High-modulus options (e.g. Arbomeric MP20) handle structural joints. Polysulphides (e.g. Arbokol AG2, Arbokol 2150) provide chemical resistance for floors, roofs, and water-retaining structures. Epoxy sealants (e.g. Arbokol SECURE, Arbokol 1025 SP) deliver hard-wearing seals for secure environments and pool applications. Contact ARBO® Technical Services for specific guidance.
 

5

What surface preparation is required before applying an ARBOSEAL Pro® sealant?
All joint faces must be clean, dry, and free from dust, oil, grease, loose material, and previous sealant residues. For porous substrates such as concrete and brickwork, the application of an ARBO® primer is recommended to maximise adhesion. Always consult the product-specific Technical Data Sheet (TDS) for primer and cleaner recommendations. Application should be carried out in accordance with BS 8000-16:1997 + A1:2010.
 
 

6

Where can I find technical documentation for ARBOSEAL Pro® products?
Technical Data Sheets (TDS), Safety Data Sheets (SDS), and Declarations of Performance (DoP) for all ARBOSEAL Pro® products are available for download on each individual product page at arbo.co.uk. The full ARBO® Product Catalogue is also available for download. For further technical support or specification advice, contact ARBO® Technical Services directly.
