Frequently Asked Questions

1

Why choose ARBOSEAL Pro® ARBO SAS for EPDM and Butyl sheet bonding?
ARBO® SAS is specifically engineered for the demands of EPDM and Butyl waterproofing sheet applications, providing secure adhesion to aluminium and PVCu substrates in both factory and on-site environments. Its solvent-free formulation is safe to handle in enclosed factory settings, and its 10-minute skin time supports efficient factory production cycles as well as on-site installation. With a 400%+ elongation at break, it maintains adhesive integrity even as roofing and waterproofing systems undergo thermal and structural movement.

2

What are the key benefits of ARBOSEAL Pro® ARBO SAS?
ARBO® SAS delivers a combination of rapid initial grab, long-term bonding durability, and compatibility with EPDM and Butyl materials. Its neutral-curing silicone polymer chemistry provides 25+ year service life performance, with a Shore A hardness of 30 and 400%+ elongation at break ensuring flexibility is maintained throughout the service life of the waterproofing system. Supplied in 600 ml foil packs for application with the ARBO® Foil Pack Gun, it allows accurate, controlled application in bead format.
 

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.

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.
