EXTREMELY FLEXIBLE: Flexifil has been developed to meet the requirements of heavy usage and extreme flexing on leather, such as heavily cracked seating cushions that come under constant use. Once applied to leather, it will never crack or flake out. EASY TO USE: Using a spatula or palette knife, lightly spread the filler over the cracked leather, following the direction of the cracks. Allow to dry then repeat the process until the cracks are full. Lightly sand to create a smooth finish then apply a Leather Repair Paint or Colourant. SELF-LEVELLING: The Flexifil will flow evenly into the cracks, forming a strong bond with the leather so only a small amount is required for each application. FOR BEST RESULTS: We recommend applying Leather Binder to the leather before using Flexifil; this creates a much stronger base for the Flexifil to sit on. SUITABLE FOR: Flexifil can be used to repair heavy cracks in all types of leather. From leather furniture and car interiors to clothes, shoes and even equestrian leathers.
