hi what is the best product for vertical expansion joint filler on top of the backer rods (25mm dia foam) you sell i am assuming not solvent based as you have so many products i need a little help chosing need enough for a 7 m joint 25mm wide and deep
We would recommend Sikaflex AT Connection for standard vertical connection joints to offer a flexible, over-paintable finish. If you could provide us more details on your specific application we may be able to offer an alternative - please email [email protected] with further information
