Sealing new vent April 14, 2010, 06:15:18 pm Yahoo Message Number: 111815Before I seal my roof seams with Eternabond tape, I'm going to remove the bathroom vent (fan doesn't work) and replace it with a Fantastic Fan vent. Should I first cover the screw heads with a layer of polyurethane sealant or just cover with Eternabond?Thanks, Art

Should I first cover the screw heads with a layer of polyurethane sealant or just cover with Eternabond? --- Art, when I "Eternabonded" the roof on my 2003 a few weeks back, I found that the original sealant around the vents and along the roof edges had deteriorated from around several of the screw heads, leaving them poking up. A couple of the screw heads under the strip of Eternabond that I had put on the seam between the front cap and the roof a year or so after delivery had also worked through the Eternabond. (I cut away enough of the E-bond to get a grip on the screws and tightened them about 1/4 turn, then ran another strip over the original strip.) The screws were all still tight, but to make sure that the heads didn't poke through a single-layer strip, I cut small "squares" of Eternabond and stuck one over each of the offending screw heads, *then* ran the strips. Let the little buggers try to get through now! ;-) A few of the screws in various places were put in geewhoppered at manufacturing; Lazy Daze's "fix" for the "screw ups" was a quarter-sized blob of sealant. I chiseled the blobs off, covered the screws with a little patch of E-bond, and then ran the strips. It's *such* a fun job, and one I don't want to do again for a long time, if ever, so I was careful to pay attention to the details.Joan

How come the factory (Vince) is so against Eternabond tape? I mentioned it to him last month when I was there and he was adamant about not using it. He claimed it will fail and it was a PITA to remove. Then told me it would be cost more to remove it etc. Not having first hand knowledge of the product I backed off.What gives?

Adding sealant on top of the screw heads will prevent the Eternabond from sticking to them and the frame around them. I would go with just the Eternabond, leaving the screw heads free of sealant.BTW Before gluing a fan down, I outline where the base will sit with masking tape to help contain the sealant's squeeze-out. After the sealant has been applied and the fan screwed down, carefully pull the tape up, along with the extra glue. I would let it cure for a week or two before applying the Eternabond tape. I use a small artist pallet knife, instead of a putty knife, for spreading the sealant. I find its small, thin blade gives better control. The one I use looks like a miniature mason's trowel. http://tinyurl.com/y6npq7nLarry
