Extremely flexible filler used to fix heavy cracking

  • Our most flexible filler
  • Used for repairing large areas of cracking
  • Dries clear so is easily coloured over
  • Dries in just a few minutes

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. An immensely elastic filler, once applied to leather it will never crack or flake out.

The product is quite viscous and should be applied to the leather with the use of a spatula or palette knife. It will sink into the cracks forming a strong bond with the leather. Do not put too much in, the Flexifil is self-levelling, therefore will flow evenly into each crack.

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 so that it blends in with the leather smoothly.

Flexifil is a white paste that dries slightly transparent, however with the addition of up to 10% Leather Colourant you can change the colour of the Flexifil to match any colour of leather.


Flexifil is ideal for repairing any type of cracking to all different articles of leather, from furniture and car interiors to clothes, shoes, handbags and even equestrian leathers.

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 leathers 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.

Trustpilot Reviews for the Leather Flexifil 5*

It certainly achieves its claim to fill void’s more or less permanently. Excellent adhesion.

Worked well in filling the damage to my settee. The hardest part is getting a matching colour to the existing
Allison Craggs, 15 August
My kids wanted me to dump my 30 year old sofa as 4 kids, dogs and cats had taken their toll, it was pretty scrathed, ripped ànd cracked, but ot was an expensive Benz sofa, £3000 30 years ago! It’s now like new!
Easy to apply, and definitely sealed the cracks in my leather sofa. Wish I’d known about Flexifil when I purchased the Complete Repair Kit a couple of years ago. Maybe it could be included in the Repair Kit?
