How to Install a Stair Handrail with Belzona 7311

00:00 #Belzona7311 is a fatigue-resistant adhesive, optimized for structural bonding applications requiring high mechanical strength, cleavage, and shear resistance. 
00:15 The packaging contains all the tools needed for an application.
Belzona 7311 has a mixing ratio of 3:1 parts base to solidifier, both by weight and by volume, and is simple to mix due to its ‘soft paste’ properties. 
00:27 Simply mix the components using a Belzona spatula in the recommended figure eight motion. Using the same spatula, score the mix for any remaining streakiness. 
00:43 In this video, we will demonstrate a #stair #handrail bonding application. The first step should be surface preparation. Tape could be used to mask the repair area and prevent excess product on the structure.
00:53 The mating faces have been grit blasted to the requirements of SSPC SP 10 or ISO 8501- SA 2 ½ cleanliness with a minimum average 75-micron (3 mils) profile.
01:04 As soon as the surface preparation is complete, the base and solidifier of Belzona 7311 should be mixed and applied on both the base of the handrail and the structure using a short-bristled brush, ensuring it fully wets the profiled substrates.
01:31 Then, apply an additional product to one of the mating faces creating a ‘peak’ build-up in the center. This reduces the potential for air entrapment within the bond line once both mating forces are pressed.
01:41 Now that the product is applied, the handrail is positioned on the stair set. The mating faces are firmly pressed together until reaching a maximum thickness of 2 mm (80 mils). Use clamps/ magnets/ ratchet straps, where possible. Allow the product to extrude and "squeeze out" any air pockets, followed by removing the tapes.
01:59 The product should be allowed to cure for full adhesive strength before any loads or stresses are exerted. The application is now complete.
