Water proof about everything.

Needed ingredients.

1. Mineral Spirits
2. 100% clear silicone caulking.

Empty container to mix in and a stir stick.

I used about 1/4 of the silicone tube and the quart of mineral spirits.  If I had more mineral spirits I would have thinned it more.

It's a hindsight thing, pour in the amount of mineral spirits then add silicon until it's almost as thick as water.

A drill with a stirrer makes it a lot easier because it takes a while to break down the caulk.

(edit)  I have found that mixing the Silicon and Mineral Spirits in a plastic water bottle works best.  Put in the ingredients, screw the lid on and shake.  If the bottle has one of the popup drinking spouts, just open it up, squirt out a trail, then use a brush to spread it around.  It will still cure in the bottle so use it or lose it.

Don't use an expensive brush, (I have found that if you work the brush as the silicon on the bristles cures, the brush will still be good for water based paints.  The bristles are sealed so any paints slide right off.  i have not tried oil based apints with a siliconed brush, but silicon is not paintable.

I painted the mixture on an apron as a test.  It did not change the color, nor the texture of the fabric.  Doesn't seem to have added any weight either.

I had plenty left over, so the 2'X4' piece of Luan I used to paint the apron got a coat as well. 

It soaked in almost immediately, so i flipped it over and did the other side as well.

After curing for 2 days, i poured water on both the board and the apron.

The water beaded and ran off.

I still have about a pint left.   (here kitty kitty)

Mineral spirits is not kind to all things, so make sure the material won't be harmed and have fun.

Should be good for all outdoor stuff including patio furniture.

Since the silicone soaks into the fabric and fills the voids and coats the threads, this will probably extend the life of whatever fabric you use it on.

SAFETY NOTICE!  No open flames or smoking.

Enjoy.

Does this recipe work on polyester oxford fabric?
GrumpyOldGoat (author)  greensngravy25 days ago
You will need to try it in a small, inconspicuous spot if you have doubts.

I do not know the affect may have on any manmade fabrics, other than the Flags I treat before putting them on the flagpole.

Mineral Spirits in general do not attack most fabrics.
I bought a used hamilton beech mixmaster at the goodwill and mixed up a ketchupy batch of your recipe for my Alaknak tent. I applied it onto the outside tent top liberally to the seams and the entire top. Looks like it penetrated and adhered very nicely. I will keep you in thw loop once it starts to rain here.
GrumpyOldGoat (author)  greensngravy18 days ago

Good idea for mixing a batch.

Let me know how your project works when it's raining.

Completed painting a nice thick coat onto the outside tent top yesterday and last night it stormed pretty good. This morning I opened the tent door and found it bone dry and water pooling on the tent top with no leaks! I think it worked!
GrumpyOldGoat (author)  greensngravy16 days ago

I call that excellent planning on your part.

Glad it worked as advertised.

After the waterproofing has been applied and is dried, does it stick to itself when folded??

MarkL23 MarkL2320 days ago

Not thick, I am looking to waterproof tent siding on a pop up trailer. I just want to make sure it wont stick to other layers as it is in the lowered position.

GrumpyOldGoat (author)  MarkL2320 days ago

You should be good to go then.

GrumpyOldGoat (author)  MarkL2320 days ago

No, but the question raises another question....

How thick of a coat are you planning on putting on the article?

Most of the fabric I have coated the silicon is thin enough to soak in between the threads and not leave a layer that is thick enough to cause any problems.

Thank You for checking it out, and I hope it works well for your purposes.

what is the price of the made 1 liter? Is it as good as Always Dry products?

GrumpyOldGoat (author)  bandurenko3 months ago

I make no comparisons to other Instructables or commercial products.

The 'cost' will vary from maker to maker and the cost of materials and the concentration.

I actually tried this last night and I'm anxious to test the pieces of fabric out. My only concern is that I'm waterproofing a backpack that I am selling and I don't want any of my customer's walking around like complete fire hazards. I can't find anything that states that the mineral spirits loses flammability as the vapors go away. Please help!

GrumpyOldGoat (author)  alybianca4 months ago

The fumes are the flammable part of mineral spirits.

I have never put a match to silicon caulk to see if it is flammable.

yes how long does it last i am interested in this idea, and i look to coat clothes that will be wet most of the time., can it last a year being emerged in ocean water and washed every 2 days??

GrumpyOldGoat (author)  coolboysix65 months ago

There are too many variables in your question. I cannot predict anything because it will depend on the saturation of the Silicon in the fabric, the type of fabric, the detergents used as well as the absorption the fabric is capable of.

It will not provide the protection of high quality rain gear that is designed for your job description.

That being said, if you get it into the fabric in a dense enough coating for your requirements it will not breathe well and probably feel clammy in short order.

Try a top and pants in a light gel to nearly liquid consistency, roll it on, then force it into the fabric with a squeegee to ensure penetration.

Let it cure and try it.

The Silicon caulking i use has a 50 year life expectancy.

I wish you luck.

how long does the water proofing last for after washing?? a particular beeze wax method described on another site claims if you heat beeze wax until melted, applying a thick coat over the material will be proofed for a year.

The Silicon I used has a 50 year life expectancy. A lot will depend on the penetrations and density of the silicon caulking in the mixture.

cam.beveridge5 months ago

also can this be used on coloured fabrics without affecting the colour of the fabric?

I love this idea, and would like to make my snowboard and hunting jackets more waterproof, but i have a couple concerns.

Mostly about the use of Mineral Spirits. Does the odor/fumes of mineral spirits wear off with time? Once mineral spirits are completely evaporated, would the jacket still be quite flammable or are the mineral spirits gone by that point? Would I be a walking fire hazard? Not that I'm planning on using these jackets around open flame, but still... seems dangerous.

Do you use your apron for your BBQ? If it was still quite flammable, wouldn't that be a dangerous idea? Please let me know. Thank you.

GrumpyOldGoat (author)  chadabshier6 months ago

When the smell is gone, the fumes are gone.

So far I have worn the apron at both gas and charcoal grills, a treated windbreaker around campfires and weed burning parties with no problems.

alohanmabuhay8 months ago

Great idea Grumpy! Do you have or could you make a youtube video showing you throwing a bucket of water on the treated items and beading and rolling off dry? That would be an AWESOME demonstration!

GrumpyOldGoat (author)  alohanmabuhay8 months ago

Youtube is for watching.

NOT for those who have never leaned, and are happy in their ignorance of how to...

But a good idea for someone, but it would just be water splashing and running off.

Are there any other names for mineral spirits or is there something that will do the same job because i cant find any in things like homebase

paint thinner/mineral spirits/white sprits

lraquet lraquet2 years ago
Is it just white spirit?
yes it is
GrumpyOldGoat (author)  lraquet2 years ago
The only other name I have found for Mineral Spirits is "Stoddard Solvent" named after one of the inventors.

Where do you live?

And have you searched the internet locally for more information?

Interesting instructable. I have a question for you Grumpy. In Greece I can't find Minerall spirits, but I can find white spirits. Wil I get the same waterproofing results by using white spirit instead of Mineral spirits. Thanks in advance.

found a local PAINT THINNER brand labeled also as "mineral spirits" or "white spirits"

GrumpyOldGoat (author)  Divemaster1 year ago
The only thing I can say is try it and see.

You may try a paint store instead of a mass marketer just to ask.

I have no idea of what, or why, they name stuff differently than what (I consider) the normal name.

Like "aluminium" instead of the (correct) "Aluminum".

I think that when it crosses our borders it changes slightly to become an entirely different metal with different names.

i tootally distroyed (for bad sttorage) a Montagne iglu tent i wonder if this could work on a that plastic fabric .. (?) (that grey paint just fall out)

Hi,
I was reading one of your posts where you said "you have a tandem 5x12.
And whether or not you could build a vardo on it?
I just so happened to start just such a project.
I had a 12x6 2 inch steel tube chassis made.

read all about and follow my progress on this sight.
I'm 1stimevardobuilder

Thanks, maybe we can share ideas.

I love that you posted this. But I was wondering is there anyway you could be used in a spray bottle. I have a lot of fabric that news weather proofed for ouroutdoor area and I don't really want to spend an entire year hand painting all of it I'm going to try it on a few scraps first to see how well it works. I was just wanted somebody had already attempted the spray bottle

GrumpyOldGoat (author)  Tiggercookies1 year ago
I have often thought about using a pump sprayer but not sure it could be cleaned adequately to to use it a second time.
I don't know if the mineral spirits would eat the innards to prevent a second use either.

Maybe a cheap 1 qt hand held pump sprayer would be the best to start with so you're not out that much if it doesn't clean well.

If you want to give it a try and post your results back here it would be greatly appreciated by all of the users.

We like new ideas and methods for anything fun.
