How to fix rip in leather car seat

Taking one look at the cracked and splitting car seat, we figured the upholstery was beyond repair. That probably meant an expensive re-covering job, which didn’t seem likely, given the age and value of the vehicle. Not happy about the costly alternatives, we decided to give it a try ourselves. The results were well worth the effort, as this repair cost only $150 to $200, much less than a new leather upholstery job. Here’s how we succeeded in fixing the torn car seat, and how you can do the same.

Prep
First, do your best to clean up the old upholstery. On leather seats, usually the flat panels on the bottom and back are made of genuine animal hides, and the sides are color-matched vinyl, because of its better flexibility. We discovered that some of the apparent dirt in the grain was actually cracked and damaged leather, which would require a re-dye or color coat (which we might attempt at a later date).

Prior to proceeding with repairs, a thorough cleaning is necessary to remove other types of chemicals that might have been applied to the surface. Because water and oil don’t mix, silicone-based or petroleum treatments are the enemy.

Application
Once the material is thoroughly cleaned and scrubbed, the first stage of the repair involves applying thin layers of a repair compound with a palette knife between the torn edges of the vinyl, directly onto the white backing material. The edges are not actually joined together, as in stitching together a torn piece of fabric. Instead the repair acts as a filler/patch. After a brief warming from a heat gun to cure the patch, apply a piece of flexible material with a grain imprint that imparts a matching texture to the smooth surface of the patch.

Once that dries, clean the surface yet again, and apply a vinyl-prepping compound to ensure the color will adhere properly. To verify, do a "tape test" (using a piece of masking tape) to make sure the surface is sufficiently tacky and will accept the dye.

Color spray
Spraying on the color topcoat proved to be the trickiest part, since beige upholstery is usually the hardest to match. Experiment with a few different combinations of tints from bottles of dye to try to get the exact hue. It helps to blend the colors together.

This type of repair, which can be done on a variety of soft and hard plastics, along with leather upholstery, is more than just a stitch in time. With a bit of color sense and artistry, your repair can look as good as new.

The process
Follow these steps to repair the torn upholstery.

Step 1: Inspecting the damage – The vinyl on the sides of the leather upholstery isn’t just worn, but split in places. It looks too damaged to repair, as the stitched seam is cracked as well. The dark lines in the leather won’t come clean, because the leather is actually damaged. Spraying on a color coat is the only option here.

Step 2: Before repair – Any previously applied treatments, especially silicone-based, must be cleaned off thoroughly with a scrubbing pad and a foaming solution.

Step 3: Begin patching – After masking off the area to be repaired with tape, the patching material is applied in several thin layers with a palette knife to the exposed white backing material.

Step 4: Cure then add material – After using a heat gun to cure the repair, press a piece of flexible material with a grainy surface onto the repair area to match the texture of the surrounding vinyl. A few different types of texture are available, from satin-smooth to a pebbly grain.

Step 5: Drying – The patch dries quickly, and creates a strong, seamless bond that’s ready for a color topcoat.

Step 6: Fill and sand – A filler/adhesive is used in the damaged areas of the seam, which is then sanded down smooth to the same level as the rest of the stitched area.

Step 7: More prep – Additional cleaner and vinyl prep are then applied so the color coats will adhere.

Step 8: Matching the color – Various combinations of color tints are mixed into the cup of a spray gun. Matching the color precisely will be the biggest challenge, particularly for beige.

Step 9: Color and condition – Once you have a match, apply a few light coats of color. The last step is to apply a conditioner to the upholstery.

Step 10: Final step – With the exception of re-dyeing the vinyl, the repair is done and the job complete.

If you walk around with tools in your pockets, don’t be surprised if you tear a hole in your leather car seat, sofa or easy chair. If a perfect repair is important, call a pro to fix it (about $150). But if you just want to prevent further tearing, you can fix it yourself with a leather/vinyl repair kit. The kit is inexpensive, and the repair takes only an hour. (Here are 100 more car repair tasks you can do on your own.) But don’t expect perfection. You’ll still see the tear, and you probably won’t get a perfect colour match.

Buy a leather repair kit at any hardware store, home centre or auto parts store. Follow the cleaning instructions in the kit and trim the damaged area to remove any frayed edges. Then cut the backing fabric so it extends under the tear by at least 1/2-inch. Glue it in place and let it dry for the recommended time.

Then mix the heat-set coloured filler. This is the hardest and most frustrating part of the car seat repair. But take your time and get as close to the colour as you can. Apply just enough colourant to fill in the tear. Then cover it with the textured mat and apply heat.

Touch the heating tool (included with the leather repair kit) to the face of a hot clothes iron. Then press the hot tool onto the textured mat and hold it in place. Let it cool and remove the mat. The patch won’t be perfect. But it sure beats the look of a tear or burn. Next, find out how to fix cigarette burns in your car.
