What was once called vinyl or simply “faux leather,” and was known for its stiff, sticky, cold, and artificial look and feel, has undergone a transformation. Modern faux leather materials, ranging from bi-cast leather by-products to polyurethane products, are more durable and closely resemble real leather. Faux leather options are more animal-friendly, and most importantly, a faux leather sofa is less expensive than the real thing. However, if not kept moisturized, it tends to crack and is vulnerable to small tears and punctures. Repair is possible with the help of a leather repair formula.
What is bi-cast, bonded, or faux leather?
They are all the equivalent of inexpensive particleboard:
- Bi-cast leather is a crust (the lower, weaker half of a hide) covered with a urethane or polyurethane coating; Bonded leather is a composite fabric made from shredded leather scraps covered with a polyurethane “skin”;
- faux leather is a polyester fabric coated with polyurethane.
- While bicast leather can last for several years before peeling, bonded and faux leather are known to delaminate in as little as 18 months. Manufacturers casually call this “hydrolysis failure.” Even the best commercial-grade polyurethane resins are only expected to last 7 years. They’re touted as more environmentally friendly than vinyl (PVC), but their disposable nature makes them prohibitively expensive and wasteful. To learn more, visit m3i-zero.fr!
How to repair faux leather? Sand the torn area only if the faux leather surface is frayed or cracked. Gently sand the area with an abrasive pad, if one is included with the leather repair kit, or use fine-grit sandpaper. This removes oils and contaminants, scuffs the fabricated surface, and removes loose fibers for a smooth repair. Wipe the treated, torn area with the cleaner included in the leather repair kit. You can also use rubbing alcohol and a soft cloth to dab the area. Do not oversaturate the surface. Alcohol is drying, which encourages the material to dry out and crack.
Simply remove dirt and debris in preparation for the repair.
- Trim any edges that extend upward, like a lip. Use small, sharp scissors or a precision cutting blade, if available. Aim for a smooth surface once completed so that the repair is as flawless and unobtrusive as possible. Cut a piece of canvas slightly larger than the tear, except for the smallest holes. For example, a tear so small that it would simply need to be enlarged to accommodate the canvas doesn’t require a canvas backing. Use the material provided in the kit or a small piece purchased from a fabric store. Insert the material into the tear, position it, and then flatten it with tweezers. Mix the repair adhesive with the provided shade in the included mixing tray or in a cup if using a two-part repair kit. Follow the manufacturer’s instructions for mixing the formula. Skip this step if using a one-part, dye-free repair adhesive formula.
- Squirt the repair glue or spread it with a small tool, depending on whether you’re using a one-part or two-part formula, under the edges of the tear. Circle the entire opening with glue so the canvas adheres to the edges of the tear. Press the edges of the faux leather against the canvas so they look natural, and hold them for a few minutes—as directed on the product—until the glue dries. Apply filler if the hole is deep and the first coat of glue makes it look sunken. In this case, use a product included with a leather repair kit. Spread the filler, apply heat with a hair dryer or as directed in the product instructions, and repeat until the surface is flat. Then apply the provided colorant with a sponge and sand as directed. Apply a second coat of adhesive over the first coat if you didn’t use filler. Smooth the edges, working quickly to prevent the adhesive from setting and creating a sticky, uneven mass.
- Lay a piece of grain paper, if included in the kit, over the repair and press it firmly into place. Wait a minute or two, or follow the instructions, then peel off the paper to leave a grain pattern on the faux leather. You can also use a piece of leather or faux leather to create this pattern. Repairing Faux Leather Repairing faux leather first requires a careful assessment of the damage. It is essential to determine whether the surface is simply scratched or has more significant tears. Proper preparation of the damaged area is crucial to ensure a lasting repair.
- Before beginning the repair, it is advisable to clean the affected area.
- To remove dirt and residue, use a mild cleaning product or rubbing alcohol on a soft cloth. This ensures the adhesive or sealant adheres properly to the leatherette. For tears, it is often necessary to use a cloth backing behind the area to be repaired. This helps reinforce the repair and prevent the tear from expanding. Make sure the piece of cloth is slightly larger than the tear for adequate coverage. After applying the glue and backing, it is important to allow the repair to dry properly. Follow the manufacturer’s instructions regarding drying time, as this varies depending on the product used. Once dry, you can apply a dye to blend the repair with the rest of the surface.
- Finally, for a realistic finish, use the grain paper included in the repair kit or a piece of leather to mimic the pattern of the leatherette. This will create a discreet and professional finish, making the repair almost invisible.
