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.

beware : doesnt work with acid cured silicon (the one that smells like vinegar) but only oxime cured

saltyfruit made it!1 month ago
Hi! I did this last night, but I think I did it wrong :( I applied the mixture to a jacket, but after it dried it had that white chalky deposit spotted here and there on the jacket [see picture]. Anyone know what I might have done wrong? And what I could do to get ride of the white spots?

For context, I used about a quarter of the same silicone tube as in the picture and about a quart of the minerals like the author said he used. Checked to make sure all the silicone had been dissolved, and the mixture was about as thick as watery glue or maybe oil.

I'm thinking maybe I could use more mineral spirits and rub at those sections with a toothbrush to dissolve the deposit? Any input or comments?

It worked though, definitely is waterproof though! I poured water on it and it beaded off. Also saw the surface I accidentally spilled some of the solution on and after the rain this morning the water was beaded on the surface.

The only thing i can think of is maybe the mineral spirits lifted something out of the fabric.
Maybe detergent residue that wasn't rinsed out completely?

Let me know if a toothbrush and mineral spirits might dissolve and lift the spots out.

ACTUALLY i had just thought of that myself! I did wash this jacket recently because I wanted it to be clean before waterproofing BUT i had only hang dried it after since i didn't want to use the dryer. I really think its detergent. I'm wondering if water and a tooth brush might be a better choice. I'll post with updates. Thanks for the quick reply!

GrumpyOldGoat (author)  saltyfruit1 month ago

The problem with water is if the residue is already waterproofed it will be wasted elbow grease.
I hope something works.

Yes that's my fear as well. All I can hope is it worked. I soaked the jacket in a bucket of hot water and scrubbed it up with a toothbrush on all the patches of white until they went away. It's drying now so I'll update later :)

Also! The jacket is 100% cotton if that helps

Does this recipe work on polyester oxford fabric?
GrumpyOldGoat (author)  greensngravy2 months 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)  greensngravy2 months 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)  greensngravy2 months 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 MarkL232 months 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)  MarkL232 months ago

You should be good to go then.

GrumpyOldGoat (author)  MarkL232 months 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)  bandurenko5 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)  alybianca6 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)  coolboysix67 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.

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)  chadabshier8 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.

alohanmabuhay10 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)  alohanmabuhay10 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?
