COLOURLOCK Fluid Leather Filler

Minor damages can easily be repaired with COLOURLOCK Fluid Leather, a coloured filling material which can be used on small holes, tears, deeper scratches and cracks. COLOURLOCK Fluid Leather has filling and adhesive properties and remains soft and flexible after drying.

COLOURLOCK Fluid Leather is a repair filler, not a colour-matched finish.

It may be lightly tinted to make application and coverage easier, however this tint is not an exact colour match and is not designed to be used as a final finish.

The priority of Fluid Leather is strength and flexibility, so the ratio of filler to pigment is optimised for durability - not colour accuracy. Because of this, it will not visually match your leather once dry.

For this reason, all repairs done with Fluid Leather must be finished with COLOURLOCK Leather Fresh, which restores the correct colour and gloss level to blend the repair seamlessly.

PREPARATION

• COLOURLOCK Fluid Leather is only recommended for damage where a filling is necessary. For scratches and general wear-and-tear on the colour surface we recommend smoothing the surface with the COLOURLOCK Leather Sanding Pad and refreshing the colour with COLOURLOCK Leather Fresh.
• The surface of COLOURLOCK Fluid Leather is smooth and shiny after drying. To hide the repair, apply COLOURLOCK Leather Fresh in the respective colour to the area. This covers the gloss of the COLOURLOCK Fluid Leather. Lightly dab the COLOURLOCK Leather Fresh several times with a sponge on the repair and dry with a hair dryer between layers until the desired covering is achieved.
• Degrease the repair area with COLOURLOCK Degreaser in order to remove care product residue.
• Smooth rough areas and scratches with the COLOURLOCK Leather Sanding Pad before starting any repairs with COLOURLOCK Fluid Leather.
• For hardened leathers, always perform repairs with COLOURLOCK Fluid Leather before any treatment with COLOURLOCK Old Leather Softener. This oily treatment would reduce the adhesion of the COLOURLOCK Fluid Leather.

PROCEDURE

Fill the damaged areas with COLOURLOCK Fluid Leather and spread evenly with a spatula. Leave to dry for 1-2 hours, depending on the amount used. Repeat the procedure until the repaired area is as full and smooth as possible.

Spread evenly with a spatula.

Where there is extensive damage it’s not always possible to smooth the surface evenly just by using the Spatula. Such areas have to be reworked. COLOURLOCK Fluid Leather cannot be sanded dry. This would damage the repair.

We recommend using the COLOURLOCK GLD Pen to smooth the repair. The GLD Solvent slightly dissolves the surface of the COLOURLOCK Fluid Leather and provides a smoother finish.

Open the lid of the COLOURLOCK GLD Pen and press down the felt tip several times until it is moistened. If the felt tip gets too moist, remove the excess quantity by cleaning it with a cloth. Smooth the repair area carefully with the moistened felt tip. When the repair area is wet with GLD, an additional treatment with the COLOURLOCK Leather Sanding Pad can be done to smooth the repair area. Always work with a small amount of GLD to prevent the repair area from becoming too dissolved. Using GLD, a repair can be adjusted to achieve the best possible result.

Professionals can repair the graining on a work area using a Repair Grain. Usually, old leathers are smooth and do not need a new graining.

The tip of the COLOURLOCK GLD Pen can be removed and reversed when worn. Especially when working on a new colour, it is necessary to change or turn the felt tip upside down.

Finally, repairs with COLOURLOCK Fluid Leather must be recoloured with COLOURLOCK Leather Fresh to balance differences in colour and gloss. In order to cover the COLOURLOCK Fluid Leather sufficiently, the COLOURLOCK Leather Fresh should be dabbed onto the area several times and dried between the layers with a hair dryer. After 24 hours treat the leather with Leather Protector.

A HOLE WITH MISSING LEATHER

Holes should be reinforced before repairing by gluing a thin piece of cloth underneath the hole with COLOURLOCK Leather Glue. Cut out a small piece of the original leather from a hidden area and adjust its shape according to the hole. Use the COLOURLOCK Leather Glue to glue it onto the piece of cloth and the edges of the hole. Close the visible rims with COLOURLOCK Fluid Leather.

A TEAR IN THE LEATHER

Leathers with big tears must first be examined in order to decide whether it would be better to replace the weak leather. Especially long tears in old and rough leathers, or in areas of high use, are often irreparable or not durable enough after a repair. We recommend the repair of tears only on stable leathers and only if the tear is no larger than a few centimetres.

Procedure: Minor tears which are not under tension should be provisionally glued with COLOURLOCK Leather Glue from edge to edge. Then close the tear with COLOURLOCK Fluid Leather, as explained.

Tears under high tension should be backed by thin cloth. In the case of very large tears and/or very rough leathers, it is advisable to sew the leather with a thin but strong thread. Place a seam every 3-4 centimetres with the starting knot on the leather's reverse. Cover the thread with COLOURLOCK Fluid Leather.

If the leather is not too rough, drill a small hole to the right and the left of the tear (approximately 2-3 millimetres) and sew with a round needle. Lay the knot underneath and pull the tear together. Tears in areas of frequent use should always be replaced by new leather when they are too large; the same is true for weak or hardened leathers.

In cases like these, it is more advisable to replace the leather.
