Product Overview

Leather Bond-3D by Leather Doctor is a water-based medium soft polyurethane bond for leather tears, rips, abrasions, cat scratches, and filling repairs.

Bond-3D will not lift or damage the leather finishes, unlike other dry solvent-based glue.

Bond-3D works in conjunction with leather Patch-4S as sub-patch and suede fibers as fillers.

Bond-3D is to be tested for darkening effect satisfaction on an inconspicuous or hidden spot before actual application.

How to Repair a Leather Cut-Through with Bond-3D?

1- Cut-through repairs utilize Leather Patch-4S as a sub-patch and this is bonded suede side to suede side.

2- Where tension causes the leather to open, it is stretched to an overlapping position with some pulling help.

3- Preferably the Patch-4S is bonded to one side first prior to bonding the other side to reduce the overlapping effort.

4- This is a slow-drying product thus a blower may come helpful to speed up the drying process.

5- The bonding process will require the bond to cure for tension strength, thus holding the rip in position until fully cured is necessary.

6- Vertical filling gap may be done with added matching coloring for aesthetic.

How to Repair a Fresh and Clean Accident Leather Abrasion with Bond-3D?

1- Abrasion in most cases will roughen up the leather structure with missing finishes.

2- Any soiling is removed with brushing prior to applying Bond-3D to smooth the damages.

3- Repeat application is necessary to build the smooth skin back gradually.

4- Color matching is done accordingly to the finish types. 

How to Repair a Prolonged Contaminated Leather Abrasion & Holes with Bond-3D?

* Constant abrasion with repeat compression may loosen and weaken the leather structure compound with a loss of fibers or missing parts.

* Repairs to such neglected damages may take on a holistic approach to restore systematically the damages.

1- Degreasing with Degreaser-2.2 is recommended to remove surface and penetrated oil and grease soiling in conjunction with Rinse-3.0 to remove foreign contamination.

2- Leather rejuvenation is also recommended to restore the leather's softness and strength with Hydrator-3.3 followed by Fatliquor-5.0.

3- Tightening the leather structure may be necessary to restore over-stretched leather with Impregnator-26.

4- Bonding repair with Bond-3D commence thereafter with smoothening, and filling with donor suede fiber, especially for aniline leathers.

5- Repair prepares the surface for color refinishing that follows with Adhesor-73, matching coloring, and matching topcoat that ends with rub-resistant protection with Leather Protector-B.

How to Repair Hair-on-Hide Leather Rip or Tear Repair with Bond-3D?

*Rip or tear is the result of diminished fatliquor (ionic charged fat and oil) from aging or alkaline overexposure.

1- The structure needs to be clean, pH balanced and fatliquor replenished up to 15% to supple it prior to repairing, otherwise the stiff hide may tend to tear again when flexed.

2- The repair may be performed with a bonding Patch-4S or with stitching and camouflaging donor suede fibers.

How to Repair Hair-on-Hide Leather with Bond-3D and Leather Patch-4S?

1- A 1” Patch-4S strip is sufficient to bond a rip with approximately 1/2” on both sides.

2- Bond-3D is applied sufficiently to half an inch along the rip to penetrate and the 1” Patch-4S is also applied half sufficiently.

3- The Patch-4S is placed and pressed accordingly.

4- Let naturally dry with the hair drying option before repeating the other half and align accordingly.

5- Let overnight cure and the hide is ready to flip over to proceed with cleaning the hair side.

How to Repair Hair-on-Hide Leather with Bond-3D by Stitching and Donor Fiber?

1- The hide is cross-stitched with a curve needle to hold the rip together.

2- Bond-3D is applied about ½” on both sides of the rip.

3- Donor fiber is scraped with Razor-60 from the thicker areas of the hide, especially the head and shoulder areas, and applied over the stitching camouflaging it.

4-The repair is left to naturally dry or option drying with a hair dryer.

5- Let overnight cure and the hide is ready to flip over to proceed with cleaning the hair side.
