PyroDanTheMan Posted February 20, 2017 Posted February 20, 2017 I found the best waterproofing liquid by accident. With a razor blade meeting the pinkie, Band Aids and pressure would stop the bleeding but it still leaked without pressure. Remembering I had a bottle of New Skin in the first aid kit, applied to pinkie, when dry I noticed how flexible it was and also waterproof. An experiment followed, made waterproof fuse out of crappy Visco, also gray paper fuse would burn underwater. It comes in a spray, haven't tried it yet. Only down side it comes in 1 oz. bottle. Probably as expensive as NC, but may be an alternative to someone.
lloyd Posted February 20, 2017 Posted February 20, 2017 Good time fuse is already waterproof... Just sayin' Lloyd
OldMarine Posted February 20, 2017 Posted February 20, 2017 (edited) Liquid Bandage is flexible collodion which is essentially NC lacquer in a different solvent. Ether I think..... high school was along time ago. EDIT: I have a bottle and it smells like ether and camphor which makes sense. Edited February 20, 2017 by OldMarine
CrossOut Posted March 5, 2017 Posted March 5, 2017 I use silicone based scotch guard for outdoor weather protection. Applied via aerosol spray can. You can use it to make almost anything water proof. I use it on my visco, cardboard, paper etc.. it creates a hydrophilic surface on whatever you spray. Water will bead off. If you submerge it in water it like like it stays in a air bubble.
lloyd Posted March 5, 2017 Posted March 5, 2017 Well... if it were hydrophilic, it would certainly "prove" the presence of water, providing positive "water proof". No? <grin>Lloyd 1
lloyd Posted March 6, 2017 Posted March 6, 2017 A good aliphatic resin WATERPROOF glue (like Elmer's, etc. 'brown' wood glue) will be reasonably waterproof when dried. It won't take long-duration soaking -- but then, neither will an NC lacquer coating. Lloyd
UncleBeau Posted December 18, 2018 Posted December 18, 2018 as I mentioned on another post....a very good water proofing is PVC cement.
BetICouldMake1 Posted December 20, 2018 Posted December 20, 2018 Liquid bandage is nitrocellulose with solvent and usually some type of antiseptic. So it will work but you're gonna get way more bang for your buck with some smokeless powder and acetone.
Razerwire Posted July 15, 2020 Posted July 15, 2020 I made a batch of water dynamite crackers. (black powder) I had already made a large batch of reliable slow burning sugar fuse with tightly rolled strips of cotton ball for cores that I've used for multiple projects. Anyway, I had a couple cans of lacquer made specifically for preserving chalk lines so they don't get rubbed off... The cans are designed to spray inverted. I don't build foundations anymore so I gave about 6in worth a test coat. It's fast drying. Worked great. Made fuse semi stiff but with a one inch to the case length it didn't matter. It's cheap too
markx Posted July 15, 2020 Posted July 15, 2020 Contact glues also make very decent waterproofing and they do come relatively cheap. But one has to find a suitable solvent for them to thin it down, so it can be applied more evenly and conveniently. Xylene has worked for me to thin down most contact glue formulations. Other accessible solvents are 50/60.....may work on some brands and not others, but xylene seems to bite down on most. 1
