As sophisticated and high tech as they are, modern day gadgets are susceptible to getting damaged or destroyed as a result of getting soaked in the water or spilled on by coffee or any other beverage. Waterproofing your phones, tablets, or laptops is a good way of keeping them dry and safe, regardless of how much they are soaked in water or spilled on by hot or cold beverages. Here are some practical tips on how to make things waterproof.

    1. Although some mobile phone models are designed to survive daily drops and splashes, there are others that get damaged at the slightest fall or getting soaked in the water. It is a fact that water and electronic circuitry do not mix. Here are some practical tips to make your mobile phone waterproof:
    2. Wrap the phone with a clear heat-shrink film. Make sure that the film is designed for draft-sealing windows.
    3. Use a heat gun to mold the film to the phone. Make sure you have everything covered because any missed spots can cause water to leak in and damage your phone.
    4. If you are looking for something more reliable, try vacuum-sealing the phone, using a plastic bag from a FoodSaver device. Ensure that it is not so tight that you cannot dial a number. While this solution is only a temporary quick fix, it may help keep your phone from getting damaged by water.

    1. Waterproofing a camera may be more challenging than a mobile phone. The former is more fragile and has more components than the latter, which has only few moving parts. There are water-resistant cameras on the market, but if you want to waterproof your current camera, here are some suggestions:
    2. The easiest way to waterproof your camera is to seal it in a Ziploc plastic bag. This can help protect your gadget from moisture when soaked in water.
    3. Secure both sides of the seal with silicone. This will provide a strong barrier, and will keep water from finding its way inside the delicate parts of your camera. Again this may be a temporary solution, so utmost care is still needed.

    Laptop.

    1. Just like a camera, a laptop is a fragile piece of hardware. It has delicate parts, such as spinning drives, LCD, and open ports, to name just a few. Here is how you can make a waterproof laptop:
    2. To protect the keyboard and trackpad area, cut a sheet of polyethylene.
    3. Make a flip-up skirt from 40-mil PVC to keep liquids from entering the edges, while still allowing you to use the ports and other components.
    4. For additional security, spray mineral oil lubricant on the USB, video, and power ports. Then use a custom earplug putty as an injection mold. This will help protect the side ports of your Laptop form accumulating water or any other liquids.
    5. Water or any other liquids can cause damage to your gadgets. However, these helpful tips can make your phones, laptops, or cameras still functional, even after getting soaked in the pool or bath tub.

How to Waterproof Fabrics

Meme waterproof me so you don't get a surprise next time you sit on me after it rains.jpg

There are several methods effective in waterproofing fabrics. Three procedures for waterproofing outdoor fabrics will be provided below.

  1. 1
    The first method to waterproof your outdoor fabrics involves using mineral spirits and clear silicone caulking compound.
    They can be found at your local hardware store. Waterproofing these items will not only protect the fabric from precipitation, but will prolong its life.
    Advertisement
     
    1. Use a ratio of one quart of mineral spirits to every one-fifth tube of clear silicone caulking compound. Both products are available at any hardware store.
    2. Pour the mineral spirits into a bucket first, and then add the silicon caulking compound.
    3. If you have a drill and stirring tool, stir the two until thoroughly mixed. If you have no drill, you can pour both ingredients into a two-liter soda bottle, cap it and shake them until completely mixed.
    4. Test a small spot on the fabric before applying the waterproofing mixture.
    5. Use a quality paint brush to apply a smooth coating onto the fabric. It is excellent for your outdoor furniture sets, including the seat cushions, pillows, and parasol. The mineral spirits/silicone mix must be used right away, and will not keep well. So, whatever is not used should be discarded securely.
    6. Warning: Do not expose your waterproofed fabric to flames. There should be no smoking around any fabric.

  2. 2
    The second method to waterproof fabric involves using ordinary powder laundry detergent, water, and alum.
    Alum can be purchased at your local grocery store.  
    1. Use a ratio of 0.45 kg (one pound) of powder laundry detergent to 7.5 liters (two gallons) of hot tap water (120°F to 150°F, or about 50°C to 65°C).
    2. Stir the detergent into a large bucket or basin of hot water until you have a consistent mixture.
    3. Submerge the fabric item into the solution, and keep it until it is soaking wet.
    4. Hang the wet fabric from a clothes line until it is dry.
    5. Now mix 0.25 kg (half pound) of alum with 7.5 liters (two gallons) of hot water in a basin or large bucket.
    6. Once the fabric item is dry, soak it in the alum/hot water solution for a couple hours.
    7. Once again hang the item on a clothes line until it is dry.

  3. 3
    The third method to waterproof your fabric requires soybean oil and turpentine.
    Soybean oil is in your grocery store aisle. The turpentine can be acquired at a hardware store.  
    1. First, you will need to mix a ratio of 237ml (one cup) soybean oil with 118ml (half cup) of turpentine in a large spray bottle for waterproofing smaller items.
    2. For large items, mix a bigger volume of this solution in a large basin or bucket. Be sure it is thoroughly mixed, and apply it to your larger items with a quality paint brush.
    3. Depending on your items, either hang them out to dry, or lay them on a clean flat surface to dry. Use a fan to speed up the drying process.

Note: Use a medium-bristle high quality paint brush for a better coating, and to avoid loose bristles on your fabric as you apply the waterproofing agents.

Tips

  • For your batteries, use a urethane waterproof coating. Simply apply some coating on the top edges of the battery and that's it.
  • Use a thermos or wide-mouthed bottle. They help contain liquids so they can also keep the water from coming in.
  • Condoms are not just great for population control. They are also excellent as underwater housing for your gadgets. Try them on your digital cameras, mobile phones, or even remote controls.

Questions and Answers

What is recipe and method for making cotton water proof using paraffin wax?

What is the formula and application method for making bleached cotton fabric water proof using paraffin wax.

You don't need a recipe. Simply heat your paraffin wax, use a brush to paint it onto the cotton, and then use a hair dryer to get the wax to fully absorb into the cotton. Once the wax has bound with the cotton fibers, you will have a strong and waterproof cotton fabric.

Waterproofing Sailboat Cover and Cushions?

Hello, we like to waterproof our Sail Covers outside, the seat cushions in and outside the boat. What is the best to do that? Thank you for your answer.

You can use the same recipe recommended above, which is just some paraffin wax, a paint brush, and a hair dryer. Just heat the wax, paint it onto the cushions, and then use the hair dryer to make sure the wax soaks in. Just keep in mind that you want to do this somewhere you don't mind spilling a little wax, as it can be messy when all of the wax is under the heat.

How to make an IP65-rated HDMI into IP66?

I wonder how IP66 rating can be achieved on a IP65 HDMI

You cannot do that. This is an industry standard that can be achieved in the product through factory production technology and tests (the product is specially made and tested with specific water jets at a specific pressure and for a specified time). You will have to buy a new HDMI cable, socket, or connector.

How can I make my DIY flip-flops water-poof?

I bought some plain white foam flip-flops with the idea to decorate them myself. I drew on them using sharpie, hi-lighter, markers etc. How can I now make them waterproof so I can wear them around?

Purchase some plain beeswax. This can be sourced out online or in a craft supply store in the candle making section. Rub the beeswax all over the surface areas of the flip flops. It will leave a wax coating but do not worry. Then take a blow dryer and set it to low. Melt the wax until there is no noticeable build up and let dry. Your flip flops will now be waterproof. You may need to reapply once a month depending on how often you wear the shoes.

How do I waterproof the components of a drone?

I have a quad-copter which I took apart in order to convert it into an RC boat. But I'm having trouble finding a way to waterproof the components of it in order for it to withstand water damage. I have seen people buying a spray can but I don't have the time/money to buy one. Any ideas I can do to protect my drone/future boat?

Was this helpful? Yes | No | I need help

You could try something like beeswax or a candle but that will not protect as well as something like the CorrosionX spray. For the most part, drones are fairly waterproof. Beeswax would need to be heavily applied each time you planned on using the boat in the water. There are other products used on wooden boats that are a heavy wax substance so your drone would be protected short term.

How to diy make windshield and glass water repellent. how to diy make metal hydrophobic

For the windshield, you can cut a potato in half and rub the cut side all over a clean windshield or 1/2 cup rubbing alcohol to 1 cup water. These will need to be applied regularly to get the Rain X Hydrophobic results. For metal, you would need to purchase an Oleophobic treatment. There currently is nothing DIY for metal. Some manufacturers use a laser to make metal hydrophobic but these types of lasers are industrial grade and not available for purchase on the mass market.

How to make cardboard tubes waterproof?

Hello I want to make a small homemade boat for fishing, but I don't have materials such as drums. I do however have these long cardboard tubes. So is there a way in which I can make them waterproof? Thank you.

Was this helpful? Yes | No | I need help

Not for the long term. No matter what you coat on the cardboard, it will still become water logged and you will sink. Not to mention that it is not strong enough to withhold your weight in the water. There are many other ways to make a boat. Consider the Vikings who crossed oceans in large boats made out of wood and animal fat. In this YouTube Tutorial you can see how to make a wooden boat inexpensively. My son made one of these for a school project and 4 years later, he still uses it on calm waters for fun.

Do you have a cheaper way to waterproof paper?

I would like to know a cheaper way because these options are very expensive

You could use wax paper. Take the paper and put it between two sheets of wax paper. Place a tea towel on top of the paper and wax and then use an iron to set the paper and wax. If you want to preserve something out of paper that is not flat, you can gently dip in melted white candle wax.

I want to waterproof lounge suites as business which is not silicon based?

I want a way that does not use silicon and a solution I can use with a spray gun

Because you would like to use a spray gun, your options are limited to silicone, lacquer or chalk paint. The chalk paint will have a color so this should be used when updating a piece of outdoor furniture. Something like melted beeswax would work if you sprayed fast enough while the wax stayed warm but I personally would not risk this to chance.

Is Alum treated fabric washable?

I just waterproofed some pillow covers for our patio using the detergent and Alum method. I would like to know if I can now wash them or will the Alum be washed out? Thanks!

The Alum will be less effective or completely washed out. You can reapply after you have cleaned the fabric each time. Really you should every few months anyway or more often during a rainy pattern of weather.

What is the property of the soybean oil and turpentine that makes the fabric waterproof?

My classmates and I are planning to make a project about soybean oil, then I saw this process. What property of the soybean can help me win our project and make it waterproof. I mean its a unique idea to have soybean as a waterproofing material right? Thanks, it would mean a lot.. I have tried: Yes, tried to search on Google but it just showed 'WIKIPEDIA' and we can't find the property of it WITH THOSE WORDS.

Was this helpful? Yes | No | I need help

This is because it is not really the soybean that makes the item waterproof but rather the oil itself. You can use any type of oil from flaxseed to canola to waterproof an item. Even animal fat such as bacon grease can be used to make an item waterproof. The turpentine basically seals the oil in the fabric.
