Leather sofas are durable, low maintenance and available in variations from partial leather and simulated leather to naturally all leather. Leather sofas are able to withstand a great deal of pressure and wear without tearing, but after years of use, the leather can crack. Leather is more prone to cracking when it is neglected. You can repair cracks in leather. The sooner you address it, the better the result.
Inspect the crack to determine how wide it is. Use your fingers to carefully spread it open.
Apply a thin layer of leather filler using a palette knife; making sure it only seeps into the crack. Allow it to dry for 5 minutes.
Use scissors to cut a piece of sub-patch big enough to cover the crack. Make sure the length and width of the crack are completely covered.
Apply leather or garment glue to the crack and place the sub-patch over it. Press firmly to adhere the sub-patch to the glue. Do not allow the patch to move or slip; hold it steadfast to the leather sofa until it dries.
Find the crack on the leather sofa and spread it apart with your fingers to determine its size and depth.
Squeeze leather filler into the crack, filling it. Use a palette knife to spread the leather filler evenly over the crack. Allow to dry for 5 minutes.
Sand the hardened leather filler gently using 1200 grit sandpaper. Do this until the area feels smooth.
Shake the bottle of leather furniture colourant vigorously to ensure it is well mixed. Pour 2 to 3 drops of colourant on the sponge and apply to the crack using a light pressure to make sure the colour works into the grain of the leather.
Allow the colourant to air dry.
You can use a hair dryer to speed up drying processes. If applying colourant, you may apply it to the entire leather sofa to give it an even finish.
