Can waterproof spray prevent color transfer from leather? Differences in roles and things to check before using

It's tempting to think, ``If you buy a leather bag, just spray it with waterproof spray and you'll be safe,'' but you need to think about preparing for water and color transfer to clothing separately. Products intended for water repellency do not necessarily work as a color fixer.

On days when you want to match your clothes with important clothes, instead of just relying on sprays, you'll want to check the compatibility with leather, how to use it, and ways to keep it from getting wet in the rain. Here we will explain how to choose a product and the precautions to use it safely.

Waterproofing spray and “color stopper” are not the same thing

When choosing care products, look not at the impression of the product name, but at what the product is used for. Even if there is an explanation of waterproofing or water repellency, it does not mean that it will prevent dye transfer, so please do not add the effect of color transfer on your own judgment.

cowmono iscrazy horse leatherWe provide information on color transfer to clothing. This does not mean you no longer need to be careful even after using the spray, but it is important to be aware of where the bag or strap touches, especially when matching it with light-colored clothing. [1]

Don't think that "if you use more, you'll be safe"

Coronil advises caution against spraying too close or using excessively. Instead of increasing the amount of application to increase the protection, adjust the amount, distance, and drying method according to the product instructions. [2]

When choosing, check the type and finish of the leather.

Even products labeled as "for leather" may not be suitable for all types of leather. Read the care instructions on the bag side and compare the applicable materials on the spray side with the materials that cannot be used. If you are not sure about the surface finish, do not judge by the product name alone, but check with the retailer.

Coronil also requests that the product be used in an inconspicuous area, as stains and discoloration may occur depending on the material and finish. Even if you are familiar with the product, it is best not to skip the process of checking compatibility before applying it to the entire bag. [2]

• Does the bag manufacturer or retailer allow its use?
• Is it suitable for genuine leather, brushed leather, synthetic leather, etc.?
• Are there any notes on color, shine, and texture?
• Can you follow the usage location, distance, and drying method?

The place to use it is outdoors. Don't do it indoors with the window open

Coronil recommends avoiding inhaling the spray and using it outdoors. Do not substitute outdoor use by opening indoor windows or running ventilation fans. Be careful of fire and choose a location where the spray will not spray on people, children, or pets around you. [2]

There's no need to skip safety precautions on product labels in favor of bag care. If you cannot secure a suitable place, please refrain from using it there.

Read the spray distance numbers for each product.

For example, Coronil's waterproof spray guide explains how to spray evenly from a distance of about 20 cm. However, this is an example from the company's guide and is not the same distance for all sprayers. I actually prefer the method written on the can I have [3]

Don't just copy the distance numbers, make sure that the material is dry, that you don't concentrate it in the same place, and that you dry it after use. Do not set a uniform drying time; follow the instructions on the product.

On rainy days, you need to prepare for things other than spray.

Even if you take care of the surface, it doesn't necessarily mean that the entire bag or the contents inside will be waterproof. Make decisions based on the situation, such as using a separate bag for rainy days or separately protecting items you don't want to get wet.

When using a rain cover, check the size and area it can cover. It is important not to assume that if there are areas that are not covered, such as the handles or the back, that you can protect them.

Do not spray additional water onto wet leather.

Adding a spray right after a rainy day doesn't mean you can skip the preparation before use. Coronil advises against using it on damp materials, except for some specified products. First, check how to clean the bag side if it gets wet, and avoid piling up supplies before drying. [2]

What to prioritize when you are worried about color transfer

There are some things you can do without having to buy additional supplies, such as not touching the leather you're starting with directly against white clothing, checking to see if the strap keeps touching the same spot, and changing the combination on rainy days. If the stain has already been stained, separate this from prevention and check to see if the stain is on the leather or clothing.

If you layer creams or other sprays to try to stop color transfer, it will be difficult to tell what you used to change the condition. It will be easier to choose the next course of action if you organize the supplies you used and the symptoms and consult the bag retailer.

Frequently asked questions

If I use a spray, will it always match with white clothes?

We cannot guarantee that. Please check water repellency and color protection separately, and continue to follow precautions regarding color transfer on bags.

How many weeks should I use it?

We do not set a uniform interval because it varies depending on the product and usage conditions. Check how you use the display first and don't think more is better

Can I use the spray I use for shoes on bags as well?

It is necessary to confirm that the material and finish of the bag are included in the product, and that the bag company also approves its use. You cannot make a judgment based solely on the experience of being able to use it for leather shoes.
