Works where other Stuff Fails September 30, 2009
emalinx (taylor, michigan)
The product description does no say how wide this roll is. There used to be wide and narrow versions of the product. I am taking a chance a buying it anyway because the picture shows the right number of calk strands.
The wooden covers of my crawlspace vents do not fit air tight, and the furnace air ducts are in the crawl, uninsulated. Between the crumbly cinderblock foundation, and the square of plywood used to cover the vents, there is an irregular gap that must be filled airtight before each winter. Tape won't stick, regular calk can't fill the big holes and regular calk will not stick to dirty or crumbling surfaces. If you use any other calk and it falls off in mid winter, you cannot re calk if the temp goes below zero.
Mortite is awesome. You can use the whole width, or separate the strands to make a narrower strip. It is like pliable clay, clean and easy to work with. It used to be reasonably biodegradable, made of chalks. It doesn't bond permanently, but sticks great against brick, cinder, rotted wood the problem surfaces.
Here is how I seal my vents. Remove plywood vent cover. Cut a square of closed cell foam to fit the opening. and place it into the opening on top of the screening. (I cut up the foarm mat sold to use under sleeping bags). Cut four lengths of the widest mortite (about an inch wide) and lay the strips about the opening so the center line of each strip is on the edge of the vent openting all around. The opening will be 'framed'. Press the putty lightly against the foundation, just enough to hold it it place. Carefully press the plywood vent cover back into the vent opening. The vent cover will press into the mortite lining the opening and make a great seal. Then, and this is the most important part, break off four more strips of mortite to cover the four sides of the rectangle opening. Lay each strip so half the strip overlaps the house foundation, and half overlaps the vent cover. Now you have a mortite sandwich with the edges of the vent cover. Press the Mortite tightly against the foundation of the house to make it sticke real good. Lasts all winter airtight, and my vent covers are rotted and wet. In spring, the putty comes right off
Great product, Much better than calking October 29, 2008

I used this to seal the gaps around a window air conditioner. Also use it to seal some older windows that had small air leaks. Sticks great and stays in place but is relatively easy to remove when desired. Can re-use many times. Best use is anyplace where caulking may have been used but easier removal is needed. Great for anything that is seasonally installed.
