How to remove pressure marks and creases in leather

Saturday, 10 October 2015 10:57:34 Europe/London

With everyday use, it is common to get creases on leather seats and furniture usually caused by heavy objects placed on top for a long period. Their weight will put pressure on the leather and leave a mark. Sharp items can also leave marks. Another way of getting pressure marks in leather is from prolonged use of sitting areas which stretch the leather causing it to deform and bulge. Likewise, incorrectly stored leather garments can become wrinkled.

Leather Pressure Marks and creases

Removing pressure marks requires some time and a good old massage! Yes, that is the best way to get rid of those pressure marks and wrinkles. With the help of a heat gun or hairdryer, heat the leather surface slightly (careful don’t burn it!). Once warm we can start the treatment - gently massage and pinch the damaged area in different directions for a couple of minutes trying to remove the bulge. It is important to cool the area quickly after this with a cold iron or any other cooling (dry) item you can find. 

If you are working with a piece of furniture where you can access the underside of the leather it will be easier to stretch the leather by massaging it from behind.

The longer the pressure was applied, the harder it will be to remove the mark as the leather fibres will be permanently stretched. There is no product that can be used to resolve this issue and, in most cases,, it won’t be possible to make the marks completely disappear. But great results can be achieved and the damage can be made almost invisible by applying the above method. 

Sitting areas of cars and leather furniture are more likely to get creased and deformed with time. Indentations in seat areas cannot be removed if they are too deep. Although we can work on the damage and achieve improvements, the creases will return with use, as the leather will stretch once again. 

It is likely the foam or padding inside the seat itself would also have lost its shape. Certain padding can be taken out and replaced, but once the leather fibres are overstretched repeatedly, they will never go back to their original state. Think of a piece of paper you crumple into a ball and then try to smooth out again - the creases and wrinkles will stay visible no matter how hard you try to flatten it out. 

When it comes to leather furniture, if after repeated heat and massage treatment the creases and marks are still visible, only a saddler or upholsterer will be able to fix the damage through upholstery work. Leather clothing can be more easily improved by stretching and heating it. But, if this doesn’t work, washing or dry cleaning may solve the problem. Our Colourlock Leather and Fur Wash is ideal for this. Using this product, leather garments can be hand washed or machine washed. If you are worried that the garment might lose colour during the washing process, pre-treat it with Colourlock Leather Fixative.

Since we have applied heat during this process, it is important to make sure we treat the leather to keep its moisture. We would recommend to first clean the leather with Colourlock Mild Leather Cleaner. Once cleanded, apply the Colourlock Elephant Leather Preserve to give it a soft glossy finish and maintain its suppleness. If your leather is matt, use the Colourlock Leather Protector instead to help it stay supple.

Classic Car Leather Restoration - 1959 Maserati Vignale 3500 GT Spyder

Sunday, 4 October 2015 16:32:25 Europe/London

This week we had a very exciting job. A customer needed car leather restoration on his classic 1959 Maserati Vignale 3500 GT Spyder. The Maserati 3500 GT was first produced in 1957 like the one featured on the British movie Cash On Demand, but it wasn’t until 1959 that Carrozzeria Vignale made the Spyder (convertible) version like the one we have been working on.

Initial inspection of the car showed the interiors had been completely neglected as is the case with most barn finds. The leather seats were dry, hard and with a lot of cracks which were spread all over the seats due to the extensive use for many years. The colour had faded and even a gentle wipe with some of our leather cleaner was removing colour away. But somehow these imperfections added to the value of the car and gave it its vintage look. The back seats however, hardly had any cracks or visible patina as they hadn’t been used so much. The challenge was to keep the old vintage look but to stabilise the leather at the same time and keep its original features. 

Photos of the car interior when we first saw it coming soon...

To start with, we had to take out all the seats and dismantle a lot of the interior bits like the side panels from the doors. The leather was cleaned very gently using one of our leather brushes and Colourlock Mild Leather Cleaner. It was then treated with a mixture of Licker oil and warm water and left for an entire week! Licker Oil is water soluble and is ideal to treat any old hard leather prior to it being repaired or recoloured. If the leather did not need any repairs or re-colouring a similar treatment with Colourlock leather softener would have been the ideal choice. Mixing it with water ensures that not too much grease is applied as this would reduce the adhesion power of the leather fillers and the leather dye. 

We then moved onto the other parts of the interior. Since, the back seats hadn't been used as much as the front ones there was virtually no damage or no signs of wear. This looked odd when compared to the rest of the leather in the car as these two seats looked pretty much brand new. We therefore, used special leather solvent cleaners to remove the colour and create the old patina similar to the rest of the car to give it that unique vintage look.

The radio and door cards, trims and all other areas of the interior which had cracks, rips and tears had to be glued back together using Colourlock Leather Glue. Cracks in other areas were filled using Colourlock Leather Filler and then sanded down using one of our leather sanding pads. We then proceeded to create an exact grain of the same area to put it back onto the repaired area. This helped achieve an invisible repair. 

A week later we switched our attention back to the two front seats. The mixture of Licker Oil and water had done its magic. The leather was now soft and ready to be worked on. After a quick dust down of all the surfaces, we degreased the seats using Colourlock Leather Cleaning Spirit. We then sanded the seats with a leather sanding pad to get a smooth surface. We then had to tackle the issue of lots of minor cracks which the customer wanted to be visible. His preference was to be able to see the cracks, however, leaving the cracks as they were and simply colouring on top would have given a very bad finish. This was the most challenging part of the job. We used Colourlock Neutral Binder which was applied using a sponge and dried straightaway with a heat gun. The neutral binder is a transparent liquid that when applied it sits in all the cracks and stabilises the leather. Whilst the cracks still remain visible, they do not feel scaly when you touch them. This treatment is ideal for classic car owners who want to keep the look but still want the leather re-enforced and stabilised. We then sanded the layer of neutral binder to get a smooth finish.

The next stage in the normal leather colouring process would have been to spray primer, then the colour followed by top coats to finish it off. However, with such old leather, these processes would have made it feel plastic like and hard. The old adage ‘less is more’ applied perfectly in this situation.

We therefore chose to spray a very thin layer of Colourlock Leather Fresh which is our DIY leather dye supplied individually and as part of DIY Leather repair kits. The Leather Fresh leather dye contains binding agents and top coats within the colour to make it easier for retail customers to apply themselves at home. The earlier sanding processes had taken some colour off but when we coloured we made sure we did not apply too much colour so the old vintage look was retained.This was followed by a layer of Colourlock Top Coat. Finally, a day later, the whole leather interior was protected using Colourlock Elephant Leather Preserve.

The customer was very happy with the result and so were we! A very challenging job with great results - even 007 would be proud to drive this beauty around!
