Silicone Finger Painting Party on Welding Blanket (and Harbor Freight backpack sprayer)

 

sold at harbor freight.about 7 ft by 5 ft. they are a chemically treated canvas,about $20. 

Tore a hole very easily

Any snag will open up a hole too easily.

Biggest complaint is how much fiberglass dust is in the air anytime you move it.

  Will tear easily.. 

easy to bend but have to be careful not to tear.

 Unfortunately it had small tears in a few spots right out of the bag.

 I would buy again.

I bought the 4x6 blanket to put under my small wood stove in my wall tent to protect my floor. It does a good job for what I bought it for. It's light weight and folds small for packing and storage. 

expect to be itching like crazy for a while from all the fiberglass you'll have sticking in your skin.

  Also, we were both full of fiberglass rash for days. Went through gloves, heavy pants and sweatshirts. 

If I have any negatives, it would be that the blanket sheds tiny fiberglass pieces

OH so they use that toxic PTFE treatment. Definitely good to use silicone. I'm gonna go spray the rest with the Kiwi camp spray silicone.

Habor F's welding blankets (made in Russia) are actually Linen. Linen has a higher flash point than cotton. I have used them and they are OK.

PTFE Coated Fiberglass cloth is manufactured in a 38" wide fabric.

So I put the $25 Harbor Freight Welding Blanket on top of the car since I figured not many would notice the black silicone stains. haha. https://garcomfg.com/2015/09/01/g15sil/ 

Feature: thermal insulation, fireproofing, oil resistance. ... It has very good abrasion resistance and good resistance to oils and solvents.

 

It's about half to 2/3rds covered in silicone.

That's a sideways shot. Can't really see anything more.

 I bought this blanket to cover a pellet smoker in the winter, and when i opened the blanket i noticed it shed fiberglass fibers. will this stop?

Mine is not shedding, and I've had it for a while now. If you're talking about when you first got it and opened the package, isn't that just typical "newly manufactured product" characteristics ?

But fiberglass is not a tough, robust material, it's woven glass...I doubt it will handle a lot of abuse or rough handling.

 

 

I tried to focus on the seam edges since that was the complaint about the $80 "fire blanket" - the edges were not covered in silicone.

 

So you figure it's gonna "fray" over time and then the fiberglass will "shed." But actually the edges of the welding blanket are FOLDED over. So that $80 "mat" does not have folded edges? amazing.

So this should help for now and then during the summer I can dunk the whole thing in a bucket of odorless mineral spirits-silicone. But again since my edges are folded over - it's probably not such a big problem for now.

Of course it has to fully evaporate before being by a fire. So that's why for now I used no mineral spirits.

I also bought a 4x6 welding blanket to put down under the stove. I also read in a thread about people using the car windshield reflectors under the stove as well.

 good idea but not very fire proof? I don't know - it's aluminum I guess.

  On tarp of the welders blanket I put a section of windshield reflector directly under the stove.

I have a car windshield reflector - so I'll try it - just under the stove itself. 

OK so... my hands were of course COVERED in silicone - so I used this nasty "degreaser" that worked well but was more toxic than the silicone. It's supposedly mainly citrus but has some petroleum solvent stuff in it.

So people said on this model number of backpack sprayer - it leaks at that joint. So inside the tube fits in but not that far. So I put silicone around the tube on the outside of the tube. But it's far enough back so it shouldn't cover up the opening of the tube - I hope not! haha.

So I'll leave it out for the day and then box it up later. It should get enough air to cure hopefully.
