Sealing the Vista View Windows

Hi All, Quick question. What is the best sealer to use to try to reseal my fixed curved windows on the front of the Argosy? The Glass leaks when it rains because the original gasket material has shrunk in certain spots. It's not the metal frame leaking, just the glass. Any Ideas? Thanks.

Vulkem sealer, only.

I used a razor knife to cut back the old gasket then used the blue painters tape to keep it neat and put in a pretty heavy bead of Vulkem. So far it has been holding up pretty well. Someone on here took the windows apart and replaced the seals...

Andy, The majority of the gasket is still in place. i was concerned that vulkem would be too thick to flow into the low spots. What do you think? George.

Clean and/or cut away the old Vulkem.

Clean the glass at the metal molding. Clean the metal molding at the sheet metal junction.

Install a bead of Vulkem sealer into those two areas.

If you do it correctly, you will never have a leak from those areas again.

Clean up the excess Vulkem with mineral spirits or kerosene.

Andy

While your asking Andy a question - if you don't mind.

Andy - what about Parbond - just bought 6 tubes from you to seal the outer metal frame edges of all windows. Would that not work as an edge seal on the glass/frame also.

Generally speaking, Par Bond is used for small seams and Vulkem is used for large seams.

Sealing the glass to metal flanges in the vista view and stack windows, should only be done with Vulkem.

Andy, the gap I refer to is between the actual glass and the metal frame, actually the channel that the glass gasket sits in. It can't be more than an 1/8th inch at most, and the original glass gasket fills the channel in 90% of the circumference of the glass. Won't Vulkem be too thick?, or should I apply Vulkem around the window and over the existing glass gasket? Thanks George.

The glass to metal junction, "is exactly" where you install the vulkem, "only."

In doing so, if done properly, you will never have another water leak from that source.

Say Andy, Just got to thinking, before I call you and order up some Vulkem, for the benefit of the other forum members, What is the proper way of sealing the window to the frame? What is the best way to get the Vulkem easthetically pleasing? Obviously you don't want a big globby bead of the stuff around the front windows, but Vulkem is kind of hard to spread. Most of the existing gasketing material is still flush to the frame, it's only depressed in certain spots. (where it leaks). So the Vulkem is going to be pretty thin most of the way around. Sorry for the winded question. Thanks. George

George.

Obtain some "good" masking tape, about 1/2 wide.

Cut out as much of the old Vulkem that may be on the edge of the glass at the molding.

Clean that junction so that it is chemically clean.

Install the masking take on top of the molding next to the glass, but not on the inside edge.

Install masking tape about 1/4 inch away from the molding on the glass.

Cut the tip of the Vulkem cartridge so that you get about 1/4" bead.

Apply the Vulkem between the two strips of masking tape.

You can smooth out the vulkem and remove the excess as needed. You can further smooth out the Vulkem with gasolene, kerosene, mineral spirirts, or the like.

When done smoothing out the Vulkem, simply remove the two pieces of masking tape.

Makes for a nice looking professional job, every time.

If your hands shake a little bit, have a beer before you start.

If not, then have 2 beers when your done.

The best time of the day to do this little operation, is when the sun is out, "AND" the glass and molding have considerably warmed up. Makes the Vulkem flow very nicely.

Andy

Sealing that overhead vista window

Is vulkem stiff enough and sticky enough to hold my vista glass against the frame for the long haul? I was planning on leaving the plexiglass interior pane out when I reassemble. Would you recommend a backer rod between the glass and the aluminum retainer to hold the glass?

Vulkem is sticky enough, but you cannot use it to fill the gap, since it takes several days to really cure out.

You can perhaps use some solid rigid rubber material that has very little give, to hold the glass in place, then seal it with the Vulkem.
