Leather Glue PU

Ensure surfaces to be bonded are free from dirt grease and grime; clean and prepare the leather thoroughly and allow to dry.

The Leather Glue PU needs to be dried whilst pressure is applied to form a good bond. 

The Leather Glue PU will take around 20 minutes to dry naturally (depending on temperature and humidity) and can be sped up to around 5 minutes with the use of a hairdryer in all instances.

For gluing Two pieces of leather together

If gluing two pieces of leather together flesh side to flesh side (suede side), the glue only needs to be applied to one side however, both sides can have the glue applied for a stronger firmer hold and feel.

Apply the Leather Glue PU to the Flesh side of the leather working it in so that it soaks in and darkens the leather slightly, no need to dry.

Apply a second coat so that it builds up to the surface and looks wet with the glue.

Press the two pieces of leather together firmly and leave to dry.

For securing a Leather Repair Sub Patch when the damage is all the way through the leather  

Apply the Leather Glue PU to the back (flesh or suede) side of the leather, slightly working it in so that it soaks in and darkens the leather slightly.

Apply a little more glue in the same area to build it up to sit on the surface.

Apply the Leather Repair Sub Patch to the glue and press firmly to join the patch to the back side of the leather, allow to dry.

If the back side of the leather cannot be easily accessed, the Leather Repair Patch can be fed through the damage and placed on the back. Making sure the patch is flat and smooth, the Leather Glue PU can also be placed onto the underside of the leather through the damage with the use of a pallet Knife other small tool or paint brush. Apply a generous amount so that you know that the glue has been applied to the whole area needed.

Try to apply the glue to only the back side of the leather without disturbing the Leather Repair Patch.  

Press the leather down, to make contact with the patch while trying to place back the damaged leather in the correct place so that it lines up to where it should be, then allow to dry. If any glue squeezes out of the damage, gently wipe it away with a damp cloth.   

In this scenario, as the glue needs to be dried whilst pressure is applied to form a good bond, you should continue to gently press the leather down whilst warning the area with a hairdryer, this will speed up the drying time.  

For gluing edges of damaged leather together

When using the Leather Glue PU on damaged leather when the damage has gone all the way through, it is recommended that a Leather Repair Sub Patch is used to offer the repair strength and flexibility.

After securing a Leather Repair Sub Patch and lining up all the damaged leather to where it should be, use a small paint brush or cocktail stick to place a line of the Leather Glue PU onto the edges of the damage to securely join and bond the edges together. Applying a fairly thick line of glue here so that it protrudes above the repair slightly is ok, as it will shrink down as it dries.

If there are any pieces of leather that are missing within the damage, these can be filled out after the glue has dried with the use of the Heavy filler.

After the glue has dried, the repair should be left and not used for 24 hours with it continuing to cure over seven days for maximum hold.
