    • Always test the finish remover on a small area first to ensure it doesn’t cause any damage to the leather.
    • When applying the finish remover, use a soft cloth or brush and work in small sections. Wipe away the finish remover as soon as it has done its job.

    How To Condition Leather Before Stiffening

    Conditioning your leather before stiffening it can help prevent it from becoming brittle and cracking. Here’s how to condition your leather:

    • Choose a conditioning agent specifically made for your type of leather.
    • Apply the conditioning agent sparingly and work it into the leather using a soft cloth.
    • Allow the leather to fully absorb the conditioner before continuing with the stiffening process.

    Precautions To Take When Preparing Leather For Stiffening

    Before embarking on the stiffening process, there are several precautions you should take to ensure the best results:

    • Always work in a well-ventilated area with adequate protection for your skin and eyes.
    • Follow the manufacturer’s instructions for stiffening agents carefully, including the recommended dilution ratio and application method.
    • Do not over-stiffen your leather, as this can make it too hard and brittle.
    • Allow your leather to dry completely before using or handling it.

    By following these simple steps, you can prepare your leather for the stiffening process, ensuring the best possible results. Remember, preparation is key when it comes to achieving the desired stiffness and durability for your leather project.
