Top-quality, dependable, and held to an extremely high standard.

While we generally use those three descriptors to refer to our team of specialists, we can also use them to describe Flexifil: our product that’s applied to leather so it never cracks or fades out again.  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.

Flexifil arrives as a white paste, however, we’re all about the ability to customize at Furniture Clinic. Therefore, Flexifil can be paired with our Leather Colorant: featuring 72 standard colors from our Color Chart, that allow you to change the color of Flexifil to match your particular shade of leather.


For those of you who always say “I wish I cooked more so I could make more use of my cooking utensils” we have the perfect compromise for you! The product is quite viscous and should be applied to the leather with the use of a spatula. The product is spread over the targeted crack in your leather - just like spreading butter! Flexifil will sink into the cracks, forming a strong bond with the leather.

The next steps are quick and easy. Use a hair drier to cure the filler, which should only take a few minutes to thoroughly dry. The product will shrink as it dries, so several applications may be necessary. Each layer can be sanded smooth so that it blends in correctly with the leather.


Our team uses Flexifil everyday – even outside of work, when we don’t have to! – because we’ve seen the exceptional results that this product provides. We want you to see them too, and that’s why we’ve made our online ordering process easy, in addition to having our team of specialists on-hand to answer any and all of your questions.

Leather Flexifil Coverage and Shelf Life

Store between 8°C and 30°C.

Once opened, use within 1 year.

Make sure the leather has been properly prepared.

For best results we recommend applying Leather Binder before Flexifil; this creates a much stronger base for the Flexifil to sit on.

Using a spatula or palette knife, lightly spread the filler over the cracked leather, following the direction of the cracks. The Flexifil will spread evenly into the cracks. It is best to apply several thin layers.

Allow the Flexifil to dry thoroughly. It will take roughly 1-2 hours to dry naturally, or within a few minutes with the use of a hair dryer.

Repeat the above process until the cracks are full.

The Flexifil can be sanded with 1200 grit sandpaper to create a smooth finish flush with the leather's surface.  More Flexifil can be applied if required.

To finish, simply apply Leather Colourant onto the Flexifil.




Q. What is the difference between Heavy Filler and Flexifil?

A. Our Heavy Filler is used for repairing damage such as rips, tears and holes. Whereas Flexifil is used fixing areas of cracking as it is extremely flexible.

Q. Can I add a grain effect to the Flexifil?

A. Yes, for best results we recommend using our Grain Repair. This is simply applied to the filler once it has dried and will replicate the grain, copying from the surrounding area of repair.

Q. Can I use this on vinyl and faux leather?

A. Yes, Flexifil will work on all types of vinyl or faux leather.

Q. Do I still need to colour over the Flexifil if it I add colourant into it?

A. Yes, but you will not need to apply as much Leather Colourant afterwards, making for a better finish. Any coloured filler will be a similar colour to the Leather Colourant version of the same colour, but not an exact match.

Q. My Flexifil seems to have thickened overtime, can it be thinned, if so, what with?

A. Yes, the Flexifil can be thinned by adding small amounts of Leather Binder into it, mixing thoroughly until you reach a similar viscosity as it was when it was new.

Q. The Flexifil doesn’t feel smooth with the leather, what can I do?

A. The Flexifil can be sanded smooth using 1200 wet and dry sandpaper. Sanding down the Flexfil will create a nice smooth, flush finish to the leather. You should then wipe this over with Alcohol Cleaner to remove any dust before proceeding to apply Grain Repair or Leather Colourant.
