ARBOKOL 1025 SP GREY (1.2LT)

Joint Preparation The joint surfaces must be clean and free from all contamination. Surfaces should be degreased using the appropriate surface cleaner (contact ARBO Technical Services for further information). Joint Backing Where applicable, appropriate joint filler, e.g. closed cell polyethylene foam should be used to provide the correct joint depth. All joint preparation and sealant application Arbokol 1025 SP should be carried out in accordance with BS 8000-16:1997+A1:2010 (British standard for the sealing of joints in buildings) Mixing The ratio of base to curing agent controls the performance properties of Arbokol 1025 SP and tins are filled off to an exact mixing ratio. It is vital therefore that the whole contents of the curing agent tin are added to the base tin. The 2 components must be thoroughly mixed to ensure complete homogeneity (Spiral “pig tail” mixing equipment is recommended). Application The usual application method once mixed is to fill the sealant into empty cartridge dispensers using a heavy-duty follower plate. The cartridge is placed over the hole in the centre of the plate and filled by applying steady downward pressure. Insert the plunger into the cartridge and the mixed sealant is then ready for application using an ARBO Caulking Gun. The sealant should be extruded firmly into the joint by maintaining an even pressure on the trigger of the gun.
