A jacket or coat is one of the most important items in your wardrobe, especially in the UK where rain, wind and changeable weather are part of everyday life. Whether you wear a raincoat, softshell jacket, cotton trench coat, winter coat, nylon jacket, suede jacket or leather coat, the outer fabric is constantly exposed to moisture, dirt, oil, mud and daily wear.
Over time, many jackets lose their original water repellent finish. Rain no longer beads on the surface, damp patches appear more quickly, dirt becomes harder to remove and the fabric starts to feel heavier when wet. This does not always mean the jacket is worn out. In many cases, it simply needs cleaning and reproofing.
At Nanocoating.co.uk, we sell specialist cleaning and protection products designed to help keep jackets, coats and other clothing cleaner, drier and easier to maintain:
-
NC Nano Fabric Cleaner for cleaning suitable jacket fabrics before treatment
- NC Nano Coating for Fabric, Leather & Suede for making jackets and coats water, dirt and stain resistant
Together, these products create a practical system for jacket waterproofing, coat reproofing, fabric protection and long lasting clothing care.
Quick overview and answer
If you are asking Do waterproof sprays work on jackets?, yes, they can work very well when applied correctly to suitable materials. NC Nano Coating for Fabric, Leather & Suede helps water bead on the surface instead of soaking into the fibres. It also helps reduce dirt, grease and stain absorption.
If you are asking What is the best waterproofing spray for coats?, the best option is one that is breathable, transparent, suitable for multiple materials and does not leave the fabric stiff or shiny. NC Nano Coating for Fabric, Leather & Suede is designed to protect suitable textiles, leather and suede while preserving comfort and appearance.
If you are asking How can I waterproof a jacket?, clean it first with NC Nano Fabric Cleaner, allow it to dry fully and then apply NC Nano Coating for Fabric, Leather & Suede evenly. Let the jacket cure before wearing it in rain.
If you are asking Does waterproof sealing spray work?, yes, but it is important to understand the difference between waterproof and water repellent. A spray can restore or improve water repellency, but it will not turn every coat into a fully waterproof technical shell with sealed seams.
This system is suitable for many jackets and coats, including cotton, polyester, nylon, softshell, suede, leather, canvas, denim and mixed fabric garments, subject to testing first.
Why jackets and coats need waterproof protection
A jacket is designed to protect you, but it also needs protection itself. Rain, mud, oil, pollution, sweat, washing and repeated friction gradually reduce the performance of the outer fabric. Once the protective finish weakens, water can soak into the fibres more quickly.
Unprotected or worn jacket fabric can suffer from:
-
Rainwater absorption
-
Dark wet patches
-
Mud and road dirt stains
-
Oil and grease marks
-
Reduced warmth in cold weather
-
Longer drying times
-
Fabric dullness
-
Loss of water beading
-
More frequent washing
- Faster wear and ageing
A waterproofing spray for jackets helps restore water repellency and makes the garment easier to clean. It can also reduce how often the jacket needs washing, which helps prolong its life. Want to learn more? Read our in-depth guide about water and stain repellent spray for fabric.

Some specialist waterproof garments with membranes, taped seams or factory DWR finishes may have specific care instructions. Always check the garment label before applying any treatment.
Do waterproof sprays work on jackets?
Yes, waterproof sprays work on jackets when the fabric is suitable and the product is applied correctly. NC Nano Coating for Fabric, Leather & Suede helps create a fine protective treatment around the fibres. This reduces water absorption and helps rain bead on the surface.
However, the result depends on the jacket. A tightly woven nylon jacket or softshell may respond very well. A loose weave cotton coat may become much more water repellent, but it will not perform like a professional waterproof hiking jacket in heavy, prolonged rain.
Waterproof sprays work best when:
-
The jacket is clean before treatment
-
The fabric is completely dry
-
The spray is applied evenly
-
The garment is allowed to cure fully
-
The coating is reapplied when needed
- The jacket material is suitable for treatment
For everyday rain, splashes and stains, a nano coating is a very practical solution.
What is the best waterproofing spray for coats?
The best waterproofing spray for coats should protect against rain and dirt without ruining the feel, colour or breathability of the material. A good product should not leave a sticky residue, visible shine or stiff finish.
NC Nano Coating for Fabric, Leather & Suede is a strong choice because it is designed for suitable textiles, leather and suede. It protects on a fine fibre level and helps preserve the natural look and comfort of the coat.
A good jacket and coat waterproofing spray should provide:
-
Water repellent performance
-
Dirt and stain resistance
-
Breathable protection
-
Transparent finish
-
No heavy film
-
Compatibility with multiple materials
-
Easy application at home
- Protection against everyday rain and grime
For the best result, prepare the coat first with NC Nano Fabric Cleaner.
How can I waterproof a jacket?
You can waterproof or reproof a jacket at home by cleaning it and applying a suitable nano coating. The process is straightforward, but preparation matters.
Step by step:
-
Check the care label
Make sure the jacket material is suitable for cleaning and spray treatment. -
Clean the jacket
Use NC Nano Fabric Cleaner on suitable fabrics to remove dirt, grease and old residues. -
Let it dry completely
Never apply a coating to damp fabric. The jacket must be fully dry. -
Test the coating
Apply a small amount of NC Nano Coating for Fabric, Leather & Suede to a hidden area and let it dry. -
Spray evenly
Apply the coating in controlled, even passes. Pay attention to shoulders, sleeves, cuffs, hood and front panels. -
Avoid over saturation
The fabric should be evenly treated but not dripping. -
Allow curing time
Let the jacket dry and cure before wearing it outdoors. -
Test water beading
After curing, place a few drops of water on the fabric. If they bead, the treatment is active.
Does waterproof sealing spray work?
Yes, waterproof sealing spray can work, but the term “sealing” can be misleading. A heavy seal can block breathability, which is not ideal for clothing. For jackets and coats, breathable water repellency is usually the better goal.
NC Nano Coating for Fabric, Leather & Suede does not aim to create a thick plastic layer. Instead, it helps protect the fibres while allowing the fabric to remain breathable and flexible.
This makes it useful for:
-
Daily jackets
-
Softshell coats
-
Cotton coats
-
Nylon jackets
-
Outdoor clothing
-
Leather and suede jackets
- Workwear and casual coats
It helps reduce water absorption without making the jacket uncomfortable.
Water repellent versus waterproof jackets
It is important to understand the difference between water repellent and waterproof.
- Water repellent means rain beads on the surface and rolls off more easily. The fabric remains breathable and comfortable.
- Water resistant means the jacket can resist some water penetration but may become wet under heavier exposure.
- Waterproof means water cannot pass through the material under specified conditions. This usually requires a waterproof membrane, sealed seams and specialist construction.
- NC Nano Coating for Fabric, Leather & Suede makes suitable jackets water repellent and stain resistant. It improves protection, but it does not replace a technical waterproof membrane or taped seams.
For everyday UK weather, commuting, light rain and casual outdoor use, water repellent protection is often exactly what you need.

-
Breathable protection
-
Water and stain resistance
-
No white residue
-
No sticky or greasy finish

Waterproofing a cotton jacket
Cotton is comfortable and natural, but it absorbs water quickly. A cotton jacket, trench coat or canvas coat can become heavy and damp in light rain if untreated.
To make a cotton jacket water repellent:
-
Clean with NC Nano Fabric Cleaner where suitable
-
Let the coat dry fully
-
Apply NC Nano Coating for Fabric, Leather & Suede evenly
-
Allow the coating to cure before wearing
- Reapply when water stops beading
This helps preserve the natural feel of cotton while improving everyday rain resistance.
Waterproofing a softshell jacket
Softshell jackets are popular because they are flexible, breathable and comfortable. However, their water repellent finish can weaken over time, especially after washing.
A nano coating is useful because it helps restore water repellency without blocking breathability.
For softshell jackets:
-
Clean the fabric first
-
Avoid fabric softener
-
Let the jacket dry fully
-
Apply a light, even coating
-
Focus on shoulders, hood and sleeves
- Allow proper drying time
This helps rain bead again and keeps the jacket performing better in changeable weather.
Waterproofing a nylon jacket
Nylon is often used for lightweight jackets, sports coats and rain shells. It may start out water repellent, but the surface finish can wear away.
To reproof nylon:
-
Clean off dirt, sweat and oils
-
Dry completely
-
Spray NC Nano Coating for Fabric, Leather & Suede evenly
-
Avoid over applying on very smooth fabrics
- Test first to confirm compatibility
A treated nylon jacket is easier to keep clean and more resistant to rain and stains.
Waterproofing leather and suede jackets
Leather and suede jackets require careful protection. Water can mark leather, while suede can darken and stain easily.
NC Nano Coating for Fabric, Leather & Suede can be used on many suitable leather and suede jackets, subject to testing.
For leather and suede:
-
Clean gently
-
Do not soak the material
-
Test first on a hidden area
-
Apply lightly and evenly
-
Let dry naturally
-
Keep away from direct heat
- Brush suede gently after drying if needed
The coating helps reduce water marks, dirt absorption and staining while preserving the natural appearance.
How often should you waterproof a jacket?
The frequency depends on use, washing and exposure to rain.
General guidance:
-
Everyday jackets: every few months or when needed
-
Rain jackets: after washing or when water stops beading
-
Outdoor and work jackets: more frequently during heavy use
-
Suede and leather jackets: after cleaning or seasonal exposure
- Coats used occasionally: once or twice per year may be enough
A simple test is to sprinkle water on the fabric. If it beads and rolls off, protection is active. If it soaks in, clean and recoat.
Why cleaning before waterproofing matters
A jacket should be clean before applying protection. Dirt, grease, sweat and detergent residues can prevent the coating from bonding effectively.
Use NC Nano Fabric Cleaner on suitable fabrics before applying NC Nano Coating for Fabric, Leather & Suede.
Cleaning first helps:
-
Remove dirt and oils
-
Improve coating performance
-
Prevent old stains being sealed in
-
Create an even finish
-
Refresh the jacket before protection
- Extend the useful life of the garment
Do not apply coating to a wet or dirty jacket.
