Vycor Plus 4 in. x 75 ft. Roll Fully-Adhered Flashing Tape (25 sq. ft.)

A:  Better check with both manufacturers for compatibility. I used it with ever built house wrap. Very sticky and seals completely. Don't expose to direct sunlight.

A:  I know that Hydro Gap has “their own” brand of flashing they probably suggest you use, but honestly I don’t believe it makes much difference at all. It seemed very similar in material and application to this vycor stuff. I used the vycor wrap on a window install and it worked great-no leaks no problems.

A:  Cannot be exposed to sunlight. So, dont use on rv roof. RV suppliers have similar products that can be exposed to sunlight.

A:  yes you can, but it might be better to use silicone cualk. it all depends on the area you are trying to seal.

A:  This will break down under direct sun light. It can be used on an RV roof but then it must be covered up by the main roof material. This is only flashing and not a full roof system.

A:  I wouldn’t due to wind force . . . Use something with better adhesion.

A:  I used this product when installing a new window. I seems to me to be a good quality adhesive material. The only thing being on top of an rv roof would be sun exposure maybe “melting” the properties a bit but then again that may not matter at all. Its worth a shot.

A:  Most of mine was exposed for only a few days. The vycor that was in direct sunlight for a few weeks did shrink. Cover if you can.

A:  Yes, per manufacturer's instructions, maximum recommended exposure is 120 days.

A:  It cannot be left in direct sunlight. Cover ASAP!

A:  If you mean exposed to UV from the sun, I'm not sure what the manufacturer says but I have had this stuff exposed for a couple years and it was still in good condition. You will need to put staples on the edges to keep it from peeling off it if is stuck to plywood or house wrap. It stays stuck very well to aluminum or vinyl.

A:  Not sure if there is a limit, but I have some that was installed six months ago, and I still haven't installed the siding. The flashing tape looks a lot better than the house wrap that has been exposed for the same amount of time.
