Make Your T-Shirt Print Waterproof: Simple Tricks To Try

Waterproofing a T-shirt is a great way to make sure it stays stain-free. There are several methods to achieve this, and it's also possible to print on a waterproof T-shirt. If you're printing onto a waterproof T-shirt, it's best to use a screen-printing method. If you're waterproofing a T-shirt with a print on it, there are a few different approaches you can take. You can use a waterproofing spray, wax, or a special detergent. If you're waterproofing a T-shirt, it's important to note that you should always follow the manufacturer's instructions and test on a small area first to avoid any damage.

Use a waterproofing spray for cotton

If you want to make your t-shirt print waterproof, one of the simplest methods is to use a waterproofing spray designed for cotton. Most t-shirts are made from cotton, so it's important to use a spray that's suitable for this fabric.

A good waterproofing spray will make your t-shirt water-repellent while maintaining breathability. You can also use these sprays on denim, so they're a great option if you want to waterproof jeans or a denim jacket, too.

Before you start, lay your t-shirt out on a flat surface and smooth out any creases or wrinkles. You can also use an iron to ensure your t-shirt is completely flat, but be sure to let it cool down before applying any spray.

When you're ready to apply the spray, hold the can around 10-15cm away from the fabric and use long, even strokes to cover the entire surface of the t-shirt. Pay particular attention to the seams of the t-shirt, as this is where water is most likely to get in. You can use a small brush to apply extra spray to the seams, making sure to cover every part of the fabric.

Once you've applied the spray, leave your t-shirt to dry in a well-ventilated area. The drying time will depend on the product you use and how thickly you've applied it, but it's usually best to leave it for at least 24 hours. Check the manufacturer's instructions for guidance on drying times and whether the spray needs to be reapplied for best results.

Using a waterproofing spray is a quick and easy way to make your t-shirt print waterproof, and it's a great option if you're looking for a solution that won't alter the appearance of your garment.

Use wax

To make a T-shirt print waterproof using wax, follow these steps:

Step 1: Gather Your Materials

You will need a bar of wax, a hairdryer, a clean shoeshine brush, and a T-shirt you want to make waterproof.

Step 2: Prepare Your T-shirt

Ensure your T-shirt is clean and dry. If it is new, consider washing it first to allow for any shrinkage.

Step 3: Heat the Wax and T-shirt

Place the wax in sunlight or use a hairdryer to soften it. You can also use a heat gun to heat the wax, but be cautious to avoid overheating it. Additionally, heat up the T-shirt with a hairdryer to prepare it for waxing.

Step 4: Apply the Wax

Rub the wax onto the T-shirt using long strokes, ensuring the strokes do not overlap. Use your fingers to even out the wax. If the wax becomes cold and sticky, reapply heat to that area. Repeat this process until the entire T-shirt is coated.

Step 5: Heat the T-shirt Again

Once you have applied the wax, use the hairdryer again to heat the entire surface of the T-shirt. This ensures that the wax covers all areas, including hard-to-reach spots.

Step 6: Let the T-shirt Dry

Allow the T-shirt to dry for several days. The drying time can vary from 4 to 5 days, depending on the thickness of the wax coat.

Step 7: Remove Excess Wax

After the T-shirt is dry, use a clean shoeshine brush to remove any excess wax. Be gentle and avoid brushing too hard, as you only want to remove the excess and not the wax that has adhered to the fabric.

Step 8: Check for Water Resistance

To test the effectiveness of the waterproofing, dip the T-shirt into a container of water or expose it to rain. Observe if the water beads and rolls off the surface, indicating that the waxing process was successful.

Step 9: Reapply Wax as Needed

Over time, you may need to reapply wax to maintain the water resistance of your T-shirt. This can be done annually or as needed when you notice a decrease in performance.

Step 10: Care for Your Waxed T-shirt

When washing your waxed T-shirt, avoid using a washing machine. Instead, wash it gently by hand in a bucket with cold water and mild soap. Let the T-shirt air dry.

Use vinyl textile paint/ink

To make a T-shirt print using vinyl textile paint/ink, you'll need to use a screen-printing process. This method is suitable for printing on umbrellas, nylon, and similar fabrics.

The first step is to create a screen, which you'll use to apply the ink to your T-shirt. You can do this by attaching a stencil of your desired design to a fine mesh screen. Ensure that the screen is securely fastened to a frame, so it remains taut during the printing process.

Next, you'll need to prepare your vinyl textile ink. This type of ink is specifically designed for screen printing on nylon and other waterproof materials. Follow the manufacturer's instructions for mixing and preparing the ink.

Once your ink is ready, you can begin the printing process. Place your screen over the T-shirt, ensuring that the stencil design is aligned with the desired printing area. Using a squeegee, firmly pull the ink across the screen, forcing it through the mesh and onto the T-shirt. You may need to apply multiple coats of ink to achieve your desired level of opacity.

After printing, allow the ink to dry completely before handling or wearing the T-shirt. Refer to the ink manufacturer's instructions for recommended drying times and any additional curing instructions.

It's important to note that screen printing with vinyl textile ink may not be suitable for all types of T-shirts, especially those made from blended fabrics. The ink is designed to adhere directly to the fabric fibers, so the presence of certain coatings or foreign materials, such as polyester, may affect the adhesion and durability of the print. Always test the process on a small area of the T-shirt before committing to a large print run.

Use a hydrophobic chemical

If you want to make your T-shirt print waterproof, one method is to use a hydrophobic chemical. This involves purchasing a ready-made hydrophobic T-shirt that has been treated with a special solution to repel water and stains. These T-shirts are often marketed as "liquid-proof" or water-resistant rather than fully waterproof, as they may eventually soak through in heavy rain.

There are a few things to keep in mind if you decide to go with a hydrophobic T-shirt:

• The hydrophobic properties may not last forever and can diminish over time, especially after multiple washes. Some companies claim their shirts will last up to 50 washes if cared for properly.
• The shirt may shrink after the first wash, so it's important to check the care instructions and follow them carefully.
• While the shirt will resist water and stains, it may not handle all liquids equally. For example, Tabasco sauce may leave stains even on a hydrophobic shirt.
• The shirt may have a slightly stiff feel to it at first, but this should fade away with wear.
• The hydrophobic properties can help reduce body odour by preventing it from sticking to the fabric.

If you don't want to buy a new hydrophobic T-shirt, you can also try treating an existing shirt with a hydrophobic solution. This could be a more cost-effective option, but it may not provide the same level of protection as a ready-made hydrophobic shirt. Some hydrophobic solutions can be applied using a spray, while others may need to be applied with a brush or roller. Keep in mind that you may need multiple coats of the solution to achieve the desired level of protection, and be sure to follow the instructions carefully for the best results.
