no caulking gun needed!

for DIY outside sealing windows to ward off termites (it works). and the only one that survives florida heat and rain. and finally, the best feature. no caulking gun needed! makes it much safer even when on a step ladder to avoid a caulking gun for balance and safety

Flex Seal is awesome.

This stuff works wonders. I had to seal some water leaks around windows on the outside of my house and this worked wonderfully. I used to use regular caulk for things like this. Flex Seal is liquid rubber and will seal any hole or puncture and keep it secure.

Yes! Yes! Yes!

I kept trying to find the perfect Caulk for my bathroom. I think at this point, I tried everything on the market. I would use the regular caulk with the gun but, with the deep gap I had to fill, it took too long to dry and I live in a house full of the male species. 48 hours with no one showering makes my house smell a little rancid. NO amount of febreeze or candles can cover THAT. I saw the price of this caulk and it ruffled my feathers, but, I bought 2 of the clear cannisters and it was WONDERFUL. No caulk gun, no cutting the tip, just take off the tab, adjust the beading thingy and squeeze! It filled the deep gaps like a dream. By the time I made it through the 2nd can and went back to smooth everything out, it had ALREADY STARTED DRYING!!! We still waited the 48 hours to make sure everything was sealed and it's been 2 weeks with no sign of weakness or the mold coming back. I plan to give it 2 more weeks and then if there is still no mold, I will go back over it with 1 can of the white to give it that finished look.
