does anyone know of a quick drying surface glue to tack a 2" ribbon of kevlar around a corner before epoxying

I have a situation where I need to tack glue a 2" wide Kevlar ribbon around two corners and have it hold tight while I coat with epoxy.  The run is about 6' long, 1" wide and 1/2" high on both sides. I tried to just use the epoxy but the corners would lift and get air bubbles under them. Staples did not work either because it did not hold the Kevlar tight enough to the wood.   My hope is to roll on a light surface glue that does not penetrate too deep into the Kevlar fibers and also leaves the gaps between the fibers open for the epoxy to flow and saturate the ribbon. I would like it to dry relative fast but with some working time so I don't have to spend all day tamping the Kevlar down again and again.   super glue did not work.

Any ideas out there?   Someone has had to have solved this problem.  I can't believe I am the only nut that has run into this issue.    or    Maybe I am.

Someone more knowledgeable will chime in hopefully, but I use Pliobond for similar situations.  I flame it off and give it 24 hours before continuing.

If you spread the epoxy first then let it tack up so its good and sticky then press the Kevlar down.Cover with more epoxy then lay plastic sheeting over stretch it tight with tape.

Or the other way wet the Kevlar with epoxy let tack up and stick down,never tried this way but should work.

It worked    but    5 hours for the epoxy to get tacky enough to hold down the Kevlar and then I had to go back every 15 minutes to re-press it as some of the Kevlar wanted to lift away.     Thank you for your advice.  I wanted a quicker way but I got it done.

Is this an inside corner or an outside? Is the corner 90 degree? If an outside corner is it beveled?

Glass reinforcement fabrics do not go around, or fit into, sharp corners very well. If this is an side corner or edge, you might consider putting in a small epoxy filet to round it, then once the filet is tacked up lay down the kevlar. Kevlar does not wet out as nicely as glass.

The corners were rounded a bit for a smoother fit. I took the advice of tungsten and it worked but took quite a while for the epoxy to get sticky enough to hold.  It is done and holding now I get to add more epoxy and then paint.   Thank you for your advice.   hope to have my little fishing boat in the water soon.

Bob,
Drift boats have a smooth, flat bottom for a reason. Those raised strips of wood on the bottom are not going to be friendly and could be downright dangerous on waving water.

yes I know

This is just a little 8' lake fishing boat, not a river dirft boat.  It is designed after the shape of a river drift boat with a flat bottom to get into shallow places like weeds and lilly pads.   I wanted the strips to help guid the boat in a straight line while rowing and gliding.  This is my second boat project and I am learning the process before I build a bigger boat.  Also this little boat does not have reinforcing ribs so if I did put it into a rough river it would be tooth picks with in a 100 feet or two.  Eventually I will attempt a real drift boat and will be asking a lot more questions. I am taking baby steps to learn.  when I look at the projects many of you folks here have completed I thought it best to learn (by mistake sometimes) on a smaller project to ease the pain. Plus I like fishing on small lakes so the boat will at least serve a purpose.

Thank you for your comments and some day in the future I will be asking the harder questions as I take on the chalange.

PS   I will also have to learn the ins and outs of drifting a river.

Glad to hear it's a lake pram. I've done my share of river rescues over the years and It often someone who made a silly mistake. That looks like a fine lake pram. Enjoy the process and the end result.

Thank you.

I respect the water and always like to error ( if you want to call it that) on the side of caution.

If I do get around to building a real river dirft boat it will be because I have had some training with someone who know what they are doing.  Lots of training not just one go around. I junped out of perfectly good air planes. 13 hours of training for 3 minutes of thrill.  I don't just want to know what I am doing if everthing goes right, I want to know what to do if things go wrong. 

 

Good drifting and fishing if you do so.

Bob

I am back to making more sawdust for a while.

Bob, I think that you are a perfect candidate to attend the annual Wooden Boat Festival in Vida, OR at the end of the month. Lots of boats, builders and things to see. I would be happy to make sure that you get a ride and a drift boating lesson if you show up. We will have plenty of boats and very experienced boaters.

Rick,

Bummer...  I just spent a week up in Whistler Canada on vacation.  I won't be able to make it this year but will mark my calendar to pay attention for next year.   I am also right in the middle of selling one of my rental properties which will hopefully close at end of month and have to stay close for signing.  Thank you for the invite. I would love to show up next year and take a ride. I should be retired by then and have more time available to play and build.
