Hypervent adhesive -- what kind of adhesive has people used?
- Thread starter C-Nile
- Start date
Rich,
I didn't know what Hypervent was so I had to go look (Google) and they talk about joining sections by using a flap, but I didn't see what type of material it was or what type of adhesive to use. Looks like interesting stuff. I had considered DryDeck for the same purpose. This looks like it might allow the mattress to slip around some. What does it look like to you on that score?
Good luck. I have used "Barge" cement for many things. It is a rubber cement type of adhesive, a contact that works and holds and wears very well, but I don't know what there fabric is so can't say if it would work on that or not.
I'd probably ask them for a recommendation.

Hello Harvey,
Thanks for responding. Actually, I'm thinking about using double sided tape -- the stuff used for golf grips that is 2" wide. Incidentally, I just installed the Hypervent today, albeit it was installed unglued in 3 pieces. The center cushion prevents the one top and two side pieces of Hypervent from slipping, and the weight of the berth cushion keeps the Hypervent in place. One thing I did differently then what the manufacturer recommended was to allow the hypervent to extend 6 inches out and up from the edge of the cushion such that it rests against the hull. That is because the cushion fits tight against the hull. If I were to cut the Hypervent to the dimensions of the cushion, the cushion would touch the hull and prevent circulation of the air from underneath, in which case it would circumvent the Hypervent. The manufacturer suggested cutting a strip that one would place between the sides of the cushion and the hull. I thought my way would promote greater circulation.
We will be sleeping in our boat in another 2 or 3 weeks, so after our trip, I'll take pictures and report to the group on our results.
Thanks!

Due to the way I installed the Hypervent up the sides, and given that there are 3 pieces involved, it has to be taped. That's great to know that the Hypervent has worked for you in your Tomcat. On our Marinaut, the Mascoat Delta-T has done a great job of mostly eliminating condensation on the interior of the hull. However, since the water tank is located directly under the board upon which the berth cushion sits, moisture really builds up on the underside. So we are hoping we enjoy similar success to you using HyperVent
Harvey, ET. AL.:
Incidentally, I tested double-sided tape on the Hypervent fabric, and it does not hold at all. The fabric is some sort of plastic material. What is nebulous is that the instructions state, "Lay the pieces together, spread or spray an adhesive on the flap according to the directions for the adhesive." It would have been nice if they specified the type of adhesive. I read up on "Barge" cement, and am not sure if it will work or not. I'm going to contact HyperVent Marine to see what they recommend, and will let the group know the outcome of my experiments with gluing together scrap pieces.
Thanks!

C-NILE, we also used hypervent on our c-dory and loved it. Just cut it to size and glued the flaps. I used a contact spray adhesive from a wholesaler I deal with. DO NOT use Barges cement, it will eat the fabric. Found this out the hard way trying to patch canvas tarps for an outfitter I worked for, had to fix all the patches the following year. If you can talk to an upholstery shop or any place they glue foam together, they should be able to show you what product will work. The stuff I used is from George N Jackson, 840 spray adhesive. Hope this helps.

C-Nile: I ran across Hypervent online the other day... how thick is it? Seems like it would provide a little additional cushioning as well. So, it sounds like you also want to create a barrier on the sides of the cushions... great thinking, we will follow your example ... let us know the adhesive you finally use.

I'm sorry to respond late, but I just returned home after a short vacation.
Mark,
Thank you very much for your warning not to use Barges, and I'll check into the 840 Spray Adhesive. Actually, I wrote to the factory representative for advice, and he promptly got back to me stating, "We use a spray adhesive or glue sticks, but any adhesive you are familiar with will probably work. We do not recommend tape." I'm glad I gave his company the business; they have great customer service.
Mary,
While HyperVent would add a little to cushioning, I doubt you would notice it, since it will sit under 4 inches of berth cushion. I'll let you and the group know how it works, and will take extensive pictures. The material is 3/4" thick. Please check the new photo added to my album "C-Nile" showing a cross section of the HyperVent material.
Thanks everyone,
Rich

Fellow C-Brats,
I just completed installation of HyperVent in the Marinaut 215 Berth. This was necessary, because the water tank is located directly under the berth, and condensation builds up under the berth cushion. Please note that the Mascoat Delta-T does a wonderful job of insulating the hull, and it reduces the amount of condensation therein. It's a marked improvement over my CD 16 sold last year.
The type of adhesive I used was DAP Contact Stik. It looks like double-sided tape, and applies like double-sided tape, but unlike double-sided tape that does not adhere to the surface, Contact Stik is very elastic, tacky and sticks very well. Thus far, I'm pleased with the results. I chose this adhesive over contact adhesives and other glues, because my wife is highly sensitive to petrochemical fumes; Contact Stik gives off no noticeable odors.
I added a nested photo album dedicated to my HyperVent installation.
Finally, the manufacturer recommends cutting the Hypervent to fit the berth cushion, and then install a side strip of their Hypervent material between the hull wall and the berth cushion to allow the underside of the berth cushion to breath along the sides of the hull. I thought that for my situation, it would be better to cut the HyperVent pad to extend out 6 inches from the circumference of the berth cushion. I was pleasantly surprised to see that the HyperVent material conformed to the sides of the hull, resulting in ample circulation of air along its sides.
Thanks,
Rich

we put it on our Tomcat and did not have to do any glue type of any nature. It really did away with any condensation.

I now what you are saying Ted. It does pretty much stay in place, and most people may not need to glue the pieces together. In my particular situation, because the Hypervent had to be cut into three pieces and its sides extended somewhat up the hull, if it had to be glued, otherwise we were experiencing considerable slippage.
Rich
My wife and I want to thank those of you in this forum who recommended Hypervent for under the berth. We just spent last night in 45-degree temperatures (Connecticut,) and there was no condensation under the berth cushion! Incidentally, there was very little, if any, condensation on the interior hull walls of the Marinaut, which is probably due in large part to its Mascoat Delta-T coating. As I stated previously, without Hypervent, the underside of our berth cushion is conducive to condensation build-up, because it sits directly on a board located directly above our fresh water tank. We really love our set-up now, and we recommend to anyone having berth condensation issues that they may want to pursue this forum's recommendations in utilizing Hypervent as a condensation mitigation tool.

We put cheap back packing pads from Wal Mart under our mattresses, and it seems to have made a considerable difference, but have not used that in super cold weather.
The other cheap alternative is the pink foam which is used as an under lay for house siding from Home Depot.
I would guess that it would be just a bit over $100 for the Hypervent for a V Berth in a C Dory 22.

Last summer, up in Desolation, Blake on (I think) C-Flyer, had some mats in his boat, in the cockpit and hall-way that were a softer padding, but like a spun mesh out of a plastic, no metal wire parts. Seemed like that would be a good pad for under the vee-birth. I thing he said they came from "Boat Mats" but when I looked that up it didn't look the same, --> more like custom named floor "Welcome" mats.

I don't understand how there would be condensation forming under the v-berth mattress. Condensation occurs when moist air hits a cold surface. The mattress should keep the air from getting behind it (I would think). Plus the warm air rises (think exhalations) and I would expect that you'd be more likely to find condensation on the ceiling and not down low.
The only situation I see would be the condensation running down the side walls and then under the edges of the mattress.
I also don't see how a water tank in the bow would make a lot of difference. It would mostly be at ambient temperature. The only issue might be if the temperature is changing fast and the temperature of the water in the tank lags (i.e. boat warming up in the morning after a cold night). I'm planning on moving my water tank to the bow compartment and didn't think that there would be any problem with condensation as a result of that, but perhaps I need to re-think that.
We have used our boat in Nov and Dec (down to freezing temps) and had not noticed any wetness under the mattress, there was some dampness on the ceiling though.

I have heard of people using several of the cheap furnace filters to make up a hypervent like mat under the v-berth mattress. We use the hypervent material on Meander and it has worked well for us for 5 years. No glue, and with hypervent on the side of the mattress as well to allow the air to circulate. Worth the investment IMO as it really does reduce the condensation under the mattress. Yes, we did get condensation prior to the installation of the hypervent. At least in the cool climate of BC.
We have used Hypervent material under the mattresses for a few years and find that it does reduce condensation beneath the mattresses.
We have had no problem with the Hypervent sliding around, and have not glued strips to go up the hull. Covering just the horizontal surface beneath the V-berth mattresses has worked for us.
It is installed with the paper-like covering on top so there is no abrasion to the bottom of the mattresses.
The Hypervent material is designed to maintain an airspace, so it isn't compressable. At the same time, it's not going to give any additional cushioning; it's firm stuff.
It seems to work quite well and my only complaint(s) are that (1) it's expensive, and (2) the bottom side of the Hypervent will tear-up your skin. Underneath it's like thousands of half inch nylon spikes ... and they're Sharp! I would recommend cutting it slightly narrower than the outside edge of the V-berth area (particularly around the porta-potty). It you cut it "flush," that raw edge will be uncomfortable on bare skin. (Don't ask me how I learned that.). You have probably seen green doormats made from stuff that looks like stiff fake grass. Hypervent is very similar.
George&Carolyn (C-Dory Kerri On) have used something like vinyl siding beneath their mattresses, and from what I recall, it worked very well.
