The main types of waterproof sprays and their differences

There are many different types of waterproof sprays, and it is important to choose the right one for your purpose and material. Here we will explain the types and features of common waterproof sprays.

1. Silicone waterproof spray

Silicone-based waterproof sprays have a strong waterproofing effect and are often used for fabric products and outdoor equipment. However, they are not necessarily suitable for leather products . Silicone can reduce the breathability of leather and may change the texture and feel of the leather.

Also, silicone sprays create a film on the surface of the leather, so they should be avoided, especially on leather that is meant to age (e.g. Crazy Horse leather ). Silicone sprays are not recommended for leather, as they may damage the natural texture and aging of the leather.

2. Fluorine-based waterproof spray

Fluorine-based waterproof sprays are an excellent choice for leather products . They contain fluorine compounds that have a strong water and dirt repellent effect while still maintaining breathability. They repel water and dirt without damaging the leather's texture, and are widely used on leather bags, shoes, belts, etc.

Fluorine-based sprays are especially suitable for outdoor use and for waterproofing on rainy days. When used on genuine leather products , fluorine-based sprays can also be expected to protect the leather while preserving its beauty.

3. Natural ingredient waterproof spray

Natural waterproofing sprays are a chemical-free, eco-friendly option. They contain beeswax and vegetable oils and are gentle on leather, making them a great choice for those who are sensitive to synthetic chemicals or who want to be environmentally conscious.

However, natural ingredient sprays may not be as effective at repelling water as silicone or fluorine-based sprays, so they will need to be reapplied periodically. However, they are suitable for obtaining waterproofing effects while preserving the leather's texture.

4. Nanotechnology-based waterproof spray

The waterproof spray uses nanotechnology to penetrate deep into the leather fibers, providing high waterproofing and durability. The tiny waterproof particles cover the surface of the leather, preventing water and dirt for a long period of time.

Nano sprays are especially suitable for expensive leather products and outdoor gear, and when used on crazy horse leather and high-quality genuine leather products, they provide a waterproof effect while maintaining the texture and breathability of the leather.

Scientific waterproofing mechanism: Difference between water repellency and waterproofing

When choosing a waterproofing spray, it's important to understand the difference between "water repellent" and "waterproofing." Although they may seem similar, scientifically they work by different mechanisms.

What is water repellency?

Water repellency refers to the state in which water does not easily adhere to the surface of a material. A water repellent material is characterized by its ability to repel water while still retaining breathability. Water repellent sprays are often used on leather products, shoes, and jackets, and are effective in protecting materials from everyday rain and dirt.

For example, by using a water-repellent spray on PU leather products , even if water droplets form on the surface, they will run off without soaking in, preventing dirt and damage caused by water.

What is waterproofing?

On the other hand, waterproofing refers to a process that completely prevents water from penetrating into the interior of the material. Waterproof sprays prevent water from penetrating into the leather and fibers, making them highly effective against heavy rain and water.

Waterproofing sprays are suitable for regular rainy weather and outdoor use, and are ideal for products that may be exposed to wet environments for extended periods of time , but leather products need to find the right balance, as complete waterproofing can compromise breathability.

How to use waterproof spray effectively

To use waterproof spray effectively, it is important to understand how to use it correctly. Below are the specific steps.

1. Wipe off any dirt on the surface before use.

Before using a waterproof spray, gently wipe off any dust or dirt on the surface of the leather item with a soft cloth. If there is still dirt on the item when you use the spray, the dirt may become set.

2. Use in a well-ventilated place

Be sure to use the waterproof spray in a well-ventilated place. The spray mist floats in the air, so there is a risk of inhaling it in places with insufficient ventilation. In addition, to ensure that the spray dries properly after spraying, we recommend drying it in a cool place away from direct sunlight.

3. Spray from a proper distance

When using the spray, it is important to spray evenly from a distance of about 20 to 30 cm from the leather product. If you spray too close, it is easy for unevenness to occur, and if you spray too far away, the effect may be weakened. Spray evenly over the entire product so that the spray spreads evenly.

4. Dry before use

After spraying, leave it for a few hours until it is completely dry. Using it while damp not only weakens the effect, but can also stain the leather. Allowing it to dry thoroughly will maximize the waterproofing effect.

How to choose a waterproof spray and what to be careful of

When choosing a waterproofing spray, it is important to choose a product that is appropriate for the material . Fluorine-based or nanotechnology-based waterproofing sprays are generally suitable for leather products, but for suede and nubuck, special sprays must be used.

1. Choose the right spray for your material

Choose the appropriate spray depending on the type of leather and the purpose of the product. For rare leather products such as Crazy Horse leather , a spray that is highly water-repellent while maintaining breathability is best. For colored leather products, it is safe to choose a colorless, transparent spray .

2. Pay attention to the ingredients in the spray

Products that contain chemical ingredients, such as fluorine-based sprays, may adversely affect leather products, so be sure to test them on an inconspicuous area. In particular, if you choose a product made from natural ingredients, it is recommended for those who value environmental friendliness and gentleness to leather.

3. Reapply regularly

The effect of the waterproof spray is not permanent. Its effectiveness will decrease depending on the frequency of use and the environment, so we recommend reapplication every 1-2 months . Spraying frequently will help the product last longer, especially if you use it frequently on rainy days or outdoors.

FAQ: Frequently asked questions about waterproof sprays

Q1. Will using a waterproof spray change the texture of the leather?

Fluorine-based and nanotechnology-based waterproof sprays do not significantly change the texture of the leather even after use. However, silicone-based sprays can impair the breathability of the leather, so you should think carefully before using them.

Q2. Can waterproof spray be used on suede or nubuck?

Yes, there are waterproofing sprays made specifically for suede and nubuck. These materials are very delicate, so it is effective to use a special spray to protect them from moisture and dirt .

Q3. How often should I reapply the waterproof spray?

Depending on how often you use your leather item and the environment, we recommend reapplying the product every 1-2 months . If you use your leather item frequently on rainy days or outdoors, spraying frequently will help maintain the waterproofing effect.

Q4. Is there anything I should be careful of before using waterproof spray?

Before using a waterproofing spray, thoroughly wipe the surface of the leather item to remove any dirt and also test it on an inconspicuous area to make sure it does not change the color or texture of the leather .
