How to Waterproof Fabric? 

Waterproofing fabric can be a useful skill for making outdoor gear, clothing, and accessories more resistant to water and moisture. 

There are different methods and products that can help you achieve this goal, depending on the type and quality of the fabric you are working with. 

Here are some simple steps to waterproof fabri:

Choose A Waterproofing Product

There are various products that can help you waterproof fabric, such as beeswax, waterproof spray, iron-on vinyl, linseed oil, and silicone spray. 

Each product has its own advantages and disadvantages, depending on the fabric type, durability, appearance, and cost. You can find these products online or in hardware or outdoor stores.

Clean The Fabric

Before applying any waterproofing product, you need to make sure that the fabric is clean and dry. If the fabric is washable, you can wash it with mild detergent and water and let it dry completely. 

If the fabric is not washable, you can use a vacuum or a brush to remove any dust or dirt. You can also use a fabric cleaner for heavily soiled fabrics.

Prepare The Fabric

Depending on the product you are using, you may need to prepare the fabric in different ways. 

For example, if you are using beeswax, you need to heat the fabric in a dryer or with a hairdryer to make it easier to apply the wax. If you are using iron-on vinyl, you need to cut the vinyl to match the shape and size of the fabric.

Apply The Product

Follow the instructions on the product label or packaging to apply it to the fabric. For example, if you are using a waterproof spray, you need to spray it evenly over the fabric in a well-ventilated area. 

If you are using iron-on vinyl, you need to place it over the fabric and iron it with a hot iron.

Let It Dry

After applying the product, you need to let it dry completely before using the fabric. The drying time may vary depending on the product and the weather conditions. 

For example, waterproof spray may take about 4 hours to dry, while beeswax may take about 24 hours to dry.

Seal The Seams

To make sure that no water gets through the seams of your fabric, you need to seal them with a seam sealer. 

Seam sealer is a liquid or gel that fills in the gaps between the stitches and creates a waterproof barrier. You can apply it with a brush or a squeeze bottle along the seams of your fabric.

Test The Fabric

To check if your fabric is waterproofed properly, you can do a simple test by spraying some water on it and seeing if it beads up or soaks through. 

If the water beads up, then your fabric is waterproofed successfully. If the water soaks through, then you may need to reapply the product or try a different one.

How to Care for Waterproof Fabric? 

Waterproof fabric is a type of fabric that has been treated with a durable water-repellent (DWR) coating to make it resistant to water and moisture. 

However, waterproof fabric can lose its effectiveness over time due to dirt, oil, abrasion, and washing. Therefore, it is important to care for waterproof fabric properly to maintain its performance and appearance. 

Here are some simple methods to care for waterproof fabric:

Brush Off Your Gear After Each Use

One of the easiest ways to care for waterproof fabric is to brush off any dirt or dust after each use, using a soft brush or a microfiber cloth. 

This will prevent the dirt from clogging the pores of the fabric and reducing its breathability and water repellency. You should avoid using soap or detergent, as these can damage the DWR coating.

Use A Specialized Cleaner

If your waterproof fabric needs a thorough cleaning, you should use a specialized cleaner that is designed for waterproof fabrics, such as Nikwax Tech Wash or Granger’s Performance Wash. 

These cleaners are gentle and effective, and they do not contain any additives that can interfere with the DWR coating. 

You should follow the instructions on the product label or packaging and wash your waterproof fabric in cool water with a gentle cycle.

Dry Your Gear Properly

After washing your waterproof fabric, you should dry it properly to reactivate the DWR coating. You can either use a clothes dryer on low or medium heat or use a clothes iron on no steam and a warm setting. 

You should check the care label of your waterproof fabric to see which method is suitable for your garment. 

You should avoid using high heat or direct sunlight, as these can damage the fabric fibres and the DWR coating.

Reapply The Dwr Coating

Over time, the DWR coating on your waterproof fabric may wear off or become less effective, especially in areas that are exposed to more friction or abrasion, such as elbows, knees, or shoulders. 

To restore the water repellency of your waterproof fabric, you can reapply the DWR coating using a wash-in or spray-on product, such as Nikwax TX.Direct Wash-In or Granger’s Clothing Repel. 

You should follow the instructions on the product label or packaging and apply the product evenly over the entire surface of your waterproof fabric.

Seal The Seams

Another way to care for waterproof fabric is to seal the seams with a seam sealer, such as Gear Aid Seam Grip or McNett Seam Sure. Seams are potential weak spots where water can leak through, especially if they are not taped or sealed by the manufacturer. 

A seam sealer is a liquid or gel that fills in the gaps between the stitches and creates a waterproof barrier. You can apply it with a brush or a squeeze bottle along the seams of your waterproof fabric.

Store Your Gear Properly

When you are not using your waterproof fabric, you should store it properly to prevent any damage or deterioration. 

You should avoid folding or compressing your waterproof fabric, as this can create creases or cracks in the DWR coating. Instead, you should hang your waterproof fabric in a cool and dry place, away from direct sunlight or heat sources. 

You should also avoid storing your waterproof fabric with mothballs or cedar chips, as these can affect the colour or smell of your garment.

Repair Any Damage

If your waterproof fabric gets damaged by tears, holes, or burns, you should repair it as soon as possible to prevent further damage or water leakage. 

You can use a patch kit, such as Gear Aid Tenacious Tape or McNett Gore-Tex Fabric Repair Kit, to cover the damaged area with a self-adhesive patch that matches the colour and texture of your waterproof fabric. 

You can also use a needle and thread to sew up any small holes or rips in your waterproof fabric.

Avoid Harsh Chemicals

To care for waterproof fabric, you should avoid exposing it to any harsh chemicals that can harm the fabric fibres or the DWR coating. These include bleach, chlorine, acetone, alcohol, solvents, and stain removers. 

If you need to remove any stains from your waterproof fabric, you should use a mild soap or detergent and water and blot gently with a clean cloth.

Test The Water Repellency

To check if your waterproof fabric is still water-repellent, you can do a simple test by spraying some water on it and seeing if it beads up or soaks through. 

If the water beads up and rolls off, your waterproof fabric is in good shape. If the water soaks through and darkens the fabric, your waterproof fabric needs to be cleaned and re-treated with a DWR product.

Why Should You Waterproof Fabric Yourself Instead Of Buying It? 

Waterproofing fabric yourself can offer numerous advantages over purchasing pre-treated waterproof fabrics. 

Here are some compelling reasons to consider DIY waterproofing:

Cost-Effectiveness

Waterproofing fabric at home is typically more budget-friendly than buying ready-made waterproof materials. You can use waterproofing sprays, coatings, or sealants on your existing fabrics, saving money in the process.
