Roof Cement

I don't use the stuff very often but have ran into a few situations recently where it was actually the best remedy on a couple repairs. The problem is i can not find any plastic roof cement anywhere around this area anymore that is not runny and way too wet. Plastic roof cement used to be harder and worked much better. I hate the runny schiat! lol I have gone back on a couple jobs where this crap was used and water is bleeding through the mess 6 months later because the schiat is still not hardened up! W.T.F. is up with this!>>>

All of them spread easy for me. If I put a bucket in my truck, unopened, and leave it that way, I will somehow spread it into my house and from a-hole to appetite on myself. Carpet and even the dog will share in my cement spreading endeavors. :blush:

( Wife wholeheartedly agreed with this post too.) :huh:>>>

"artiscally a'spreadin tha mamy ther "

LOL........ one of yer bess lines e'r, me lad. Fer sure.>>>

YO HO HO AN A BUCKET OF THA BLACK.....ARGH!>>>

I use Henry 906 It has a tiny bit of solvent on top as it is a wet/dry patch cement. It has nice body and trowels nice and smooth. Ole Jack would be proud of me>>>

Hi, lanny. I assumed if his mastic was "runny and way too wet" that it was what Jed described as having "a little residual liquid on top." Usually that means it's 'wetpatch' which has more solvents to facilitate sticking on wet surfaces but I have seen plastic roof cement (not wetpatch) that was sloppy that way also, and like VT slater I have found Karnak pretty decent. All the modifieds seem to set up pretty quickly, even though they remain pliable. The slurpier it is the less we better use. I have reached a point where I use so little of any of the cutback products that it's not a live issue for me but in the past I have often solved the viscosity problem merely by allowing some of the solvents to take voluntary leave on their own time. I'm sure there's more chemistry to it than I am giving the mastic kings credit for, but I just strained and resurrected a thirty-year collection of latex and solvent-based paints during the last two weeks, and more often than not brute force and awkwardness will more than have its way with these baseline products, despite how strenuously any experts might object. They don't hold up to UV. They're not a membrane unto themselves. The solvents in them dissolve asphalt products. I use the runny stuff with glassply to achieve absolutely killer patchwork on built-up roofs, along with a lot of working it with a trowel to express it through the glass, but even then, it doesn't take a huge amount of it. All the excess gets screeded off and returned to the can. In a perverse sort of way, mastic that is too runny actually forces us not to use too much of it which is a good thing. Flashing compound used to work well in a lot of cases.>>>

Yeah Henry was the other good brand. Henry or Mulehide. I cant find either one around here anymore! Grrrrrr!!!! Nothing but runny azzzz shiatt!!! :woohoo:>>>

To stiffen up summer roof cement (muck) my guys would use gypsum or any other suitable talc. Oldtimers used asbestos before it was banned.>>>

egg Said: If you are in a pinch and dont mind a McGuyver-type solution, open up a couple of new cans, drain off any excess solvent on the top, and leave the lid off for a couple of days. Check it every now and then. Stir it as needed. When it has reached the consistency you want, trowel the top level-smooth, pour in an inch of water to cover it, and replace the lids. Enjoy.

I tried that thinking the same ting, but when it got up around 100f some how it ran. I use Karnak and have good luck so far.>>>

The S.O.B.'s that work for me call it "Cement Roof". It always takes me a moment to figure out what they are saying. :laugh:>>>

Yeah i think the stuff i used to like was made by MuleHide. It was wet/dry plastic cement. Can't find it anymore! :woohoo:>>>

I think shipments got mixed up and you got a load of Yankee caulk Ole Willie. I've been struggling all winter with a Dixie formulation up here and my forearms are about as big as Popeye's. :laugh:>>>

Arrrrr, well shiver me monays ther , we says for shuuuuure. Ole Jack says use tha refined kine ther, he do fer a fakt. Mister Willies Yo ho ho an a bucket of black.....Arrrrrrr>>>

Must be a northern thing. I have never heard of summer vs. winter grade. When i was a sub for years we used the shiat to seal under the shingles and on top of the vents, pipe flashings etc. ( sealing the shingles down to the metal at teh sides and top ) ( not visible ) It was always fairly hard out of the containers what ever time of year you purchased it. I did not do the work for a few years and now i am doing it again and this has changed. In the old days you could turn the bucket upside down and nothing would come out. Today the shiat would just slide right out and you would have a huge mess. I've tried several different kinds purchased at several different places. Same result! The runs!!!!! lol>>>
