ARBO

ARBO offers a wide-ranging portfolio of sealants designed to meet specific performance needs across construction and industrial applications. This includes silicone sealants like Arbosil 1096 for glazing and façade work, low modulus silicones such as Arbosil LM for perimeter sealing, and specialised polysulphide sealants like Arbokol 1025 and 2150 for movement joints. ARBO’s sealants are engineered to deliver excellent adhesion, movement capability, and resistance to ageing and weather, with product lines tailored to both modern and heritage construction.

Yes, many ARBO products are specifically formulated for exterior use and are tested to perform in the UK’s varied climate. For instance, Arbosil LM is a low modulus silicone that handles expansion and contraction in external joints without cracking or failing. It’s frequently used around windows, doors, and curtain walling systems where water ingress must be avoided. ARBO sealants remain UV-resistant, weatherproof, and flexible over time, which is essential for applications exposed to sun, rain, and temperature change.

ARBO sealants are designed to work with a wide variety of substrates found in construction, including aluminium, powder-coated metal, timber, masonry, concrete, glass, and certain plastics. Their formulation ensures good adhesion to non-porous and porous materials alike, although surface preparation and priming may be required for some substrates to achieve the best bond. Compatibility between materials and sealant type is key, especially in projects where differential movement or unusual finishes are present.

Yes, many ARBO sealants are compliant with UK and European standards relevant to building envelopes and joint sealing. Arbokol 1000 and 2150, for example, are tested to BS 5212 for joint sealants used in concrete pavements and civil works. Arbosil products often meet ISO 11600 classifications for silicone sealants. These certifications demonstrate that ARBO products are suitable for use in safety-critical or performance-sensitive environments such as hospitals, schools, infrastructure, and multi-storey buildings.

To get the best performance from ARBO sealants, surfaces must be clean, dry, and stable. Remove any dust, grease, or old sealant before applying. Some substrates may require a primer to maximise adhesion, especially on porous or dusty surfaces. Apply the sealant using a standard cartridge gun, and make sure to tool it within the open time to ensure a smooth, even finish that fully wets the joint sides. Joint dimensions, depth-to-width ratios, and backing materials all affect long-term performance, so it’s worth consulting the product data sheet to ensure the correct setup.
