KiurLab Leather Filler is a repair compound formulated to fill and rebuild damaged surfaces on closed-grain leather – both full-grain and synthetic leather – prior to subsequent colouring. The product is used as a step within the KiurLab PRO LEATHER system for professional leather restoration.

Leather Filler is applied in thin layers directly onto scuffs, cracks, and surface defects. Each layer is allowed to dry and can be sanded down to produce a smooth, even surface before colour is applied. The method provides full control over the finished result and is designed for professional use in detailing studios and upholstery workshops.

What is Leather Filler and why choose it?

KiurLab Leather Filler is a leather filler that fills surface damage prior to recolouring. Unlike direct recolouring without pre-treatment, a filling step provides a stable, even foundation that improves colour adhesion and durability. The product is part of a structured repair system and is not intended as a standalone solution.

Application is carried out in thin layers with the option of intermediate sanding, giving precision when addressing deeper damage. The result is a rebuilt surface that is ready for recolouring within the PRO LEATHER system.

Frequently Asked Questions (FAQ)

Does KiurLab Leather Filler work on deep cracks in car seats?

Yes, KiurLab Leather Filler is formulated specifically to repair scuffs, cracks, and surface defects on closed-grain leather, including car seats. For deeper damage, layer-by-layer application is recommended – apply a thin layer, allow to dry, sand if necessary, and repeat until the surface is even. The product is part of the KiurLab PRO LEATHER system and is intended to be used as a preparatory step before recolouring.

What volume does KiurLab Leather Filler come in and how many repairs will it cover?

KiurLab Leather Filler is supplied in a 9.5 ml pack. The volume is suited to targeted spot repairs rather than large-scale treatment. The number of repairs depends on the size and depth of the damage and the number of layers required per repair. The product is applied in thin layers, which contributes to economical material usage on smaller defects. We also offer complementary products from the KiurLab PRO LEATHER system for a complete repair result.

What sets KiurLab Leather Filler apart from other leather fillers on the market?

KiurLab Leather Filler is specifically formulated as a system step within KiurLab PRO LEATHER, meaning it is designed to work in conjunction with the other steps in the system – cleaning, filling, and recolouring. The product supports intermediate sanding between layers, providing professional control over surface texture. It is not intended for aniline leather, nubuck, or suede, which makes clear that KiurLab Leather Filler is aimed at closed-grain leather types where a stable foundation prior to recolouring is essential.
