Is Leather Waterproof?

This question has piqued the curiosity of many leather enthusiasts, especially those who invest in items like high-quality leather tote bags, backpacks, wallets, and similar goods. As experts in this area, we've seen various leather types, from full-grain to faux, each with its unique characteristics and levels of water resistance.

So, is there any fully waterproof leather? Let's unravel this mystery. We'll also share how to treat and "waterproof" your leather and which drying techniques are safest for your items.

Is Leather Waterproof?

Leather is highly durable with less aesthetic appeal but isn't inherently waterproof. "Waterproof" implies an absolute barrier against water, which leather doesn't possess. However, leather has a certain degree of natural water resistance due to its dense and fibrous structure. The extent of leather's water resistance varies and is influenced by its type, treatment, and age. Full-grain, top-grain, and genuine leather interact with water differently. While leather can handle light rain or occasional water exposure, prolonged contact can cause discolouration, stiffness, and mould growth.

To review:

• Water-resistant materials can handle occasional splashes or light rain but aren't impervious to large volumes of water.
• Waterproof materials offer complete protection from water damage.
• In its natural state, leather is water-resistant but not waterproof.

The Effects of Water on Leather

When leather gets wet, it absorbs moisture, leading to potential damage. Untreated wet leather loses its natural oils as the water evaporates, causing it to become brittle, prone to cracking, and susceptible to dry rot. Reconditioning leather immediately after it gets wet is essential to replenish the lost oils and prevent long-term damage.

Different Types of Leather and Their Water Resistance

Different types of leather vary in their ability to resist water:

• Full-grain leather is the most durable and water-resistant type, as it comes from the most substantial part of the hide. However, it's not waterproof and requires treatment (wax or silicone spray) to enhance its water resistance.
• Top-grain leather: Slightly less durable but still highly resistant, it can also benefit from waxing or silicone sprays to protect it from water exposure.
• Genuine leather: While the term may sound impressive, genuine leather has the least natural water resistance. It still requires treatment but is less durable than full-grain or top-grain leather.
• Suede and nubuck leather are especially vulnerable to water damage because of their delicate structure. Wax should never be used, as it can ruin the texture. Instead, specialised waterproof sprays are the safest option for these types.
• Synthetic and faux leather: Faux leathers are naturally waterproof because these leathers are made from materials like PVC or polyurethane, which don't absorb water.

How to Treat and Waterproof Leather

Waterproofing treatments help prevent the loss of natural oils in leather, which is critical to maintaining flexibility, preventing cracking, and extending lifespan. Here are some standard methods:

Waxing

Applying wax to leather adds an external waterproof layer, making it one of the most effective home treatments. Products like beeswax cream provide a protective barrier that fills the leather's pores, preventing water penetration. Waxing can be especially beneficial for full-grain and top-grain leather if the manufacturer recommends it.

Sprays

Silicone-based sprays are easy to apply and provide a thin, waterproof shell. They're ideal for everyday items like shoes and jackets but offer short-term protection requiring frequent reapplication.

Conditioning

If the manufacturer recommends it, leather conditioners can maintain the material's suppleness and help replenish natural oils lost when leather gets wet. It's most effective when applied to damp leather, allowing the conditioner to penetrate deeper and restore its moisture balance.

Proper Drying Techniques for Wet Leather

To avoid damaging your leather items, take care when drying them. Here's a handful of crucial reminders:

• Avoid unnatural heat sources: Do not use hair dryers, radiators, or heaters to dry leather, as these can cause warping, shrinking, or cracking.
• Blot excess water: Use a soft, absorbent cloth to blot the leather and remove excess water gently. Avoid rubbing to prevent damage to the surface.
• Air dry naturally: Let the leather dry in a well-ventilated area. Keep it away from direct heat or sunlight to prevent fading or stiffening.
• Be patient: Allow the leather to dry naturally to maintain its shape and texture.

When to Seek Professional Help

Suppose your leather item has suffered severe water damage, such as deep stains, mould, or cracks. In that case, it's best to consult a professional. Signs that professional restoration is necessary include significant discolouration, persistent stiffness, or dry rot. DIY methods may not fully restore badly damaged leather, and incorrect treatments can worsen the issue. 

Professionals can safely handle delicate repairs, recondition leather, and restore lost oils without further damage. They also have access to specialised products that offer better results than over-the-counter treatments, ensuring the longevity and appearance of your leather goods.

Frequently Asked Questions

Does leather turn white when wet?

When leather objects are damp and stored away, microorganisms can flourish on them, making the leather turn white over time. Climate elements can also encourage bacteria and fungus growth.

How can I waterproof leather?

The simplest method to make leather water-repellent is to wax and condition your items. You can do these tasks independently or combine them using a single product, such as beeswax cream.

Is genuine leather costly?

Yes, producing genuine leather requires significant time, resources, and expense.

Can leather withstand rain?

Leather jackets can endure rain, but constant exposure is not a good idea as it can strip away the natural oils, causing the leather to become brittle and prone to cracking. Always shield your jacket from rain using an umbrella.

Does leather become hard when damp?

Leather isn't necessarily spoiled when wet, but the chances of damage increase. Many natural oils dissipate as leather dries, leaving it dry and stiff.
