Re: Bedding Deck Hardware With Butyl Tape

What's the deal with black!???

last summer I re-bedded a newfound metals portlight that the previous owner had bought but not finished installing. I used almost 1/2" thick round black butyl rubber that he'd also purchased from them.

I missed a spot and did a craptacular job securing the port so it leaked a little bit.

So I spent an entire day pulling it off the other day. Some of it came off well, some of it pulled paint and primer off the steel, and some of it is fantastically stuck on there in tiny bits I can't ever seem to get off. If I make a ball and roll it it 'sorta' works till my fingers stick together and make and unholy mess.

I tried turpentine and Acetone, neither seem to do much of anything. It's fairly cool/cold now, would it be easier in warmer weather?

Is black always so messy? Is the grey stuff better? (I used some flatter gray stuff I bought at camping world on a different hatch the black is WAY stickier so is the grey stuff inferior?)

There are literally hundreds of formulations & products sold as "butyl tape". The majority of it is simply unsuitable for deck hardware sealing.

Some of the black is very good quality but a lot messier than is necessary. I will no longer use black and I would not sell it either.

I used the NFM black stuff when I did my ports and only wish I had Bed-It Butyl tape back then.. Lots of the grays and off whites are not true butyl tapes such as the stuff often sold at RV stores. Gray is tough to do in a good quality tape, white is next to impossible...I have been trying to get my extruder to make one in white that meets my specs but they simply can't.

The fillers needed to make it off white literally ruin the product. I've tested over 40 tapes and only a hand full are decent quality..

This is the same with polyurethane sealants. There are literally hundreds of products sold that are a polyurethane sealant like 4200, Sikaflex etc. but not all the "formulations" are the same..

Re: Bedding Deck Hardware With Butyl Tape

I tried to get roles of butyl from Toronto area yard that used to do C&C factory warranty, plus a lot of other boats. Rebedding hand rails, genoa tracks & stanchions before spring launch. Their parts guy said "I haven't seen any of that stuff for years, it's all the same, just go to a glazer". I worked in that yard for 7 years and we ALWAYS used factory spec. So, I ordered some from Mainsail, it shipped next day to my niece in DC and I'll pick it up on our turkey trip Thursday. Thanks again MS!

Re: Bedding Deck Hardware With Butyl Tape

I bought some from MS and have used it to bed deck hardware, stuff works great. I'd rather spend a little more for proper materials than to do a job more than once.

I just recently bought a Freedom 25 off EBay of all places and while I was bringing it down the intracoastal canal from Pt Arthur to Kemah, TX I got into some little showers. I noticed a few small drippy leaks from bolts on the deck/hull joint and around the compass. There was significant travail on this trip but this was at the beginning.

Having read the first page or two of this thread, I rushed out and bought some of this wonderful stuff that I knew I could get cheap from home depot. After I messed around with it a little, I came back and read the whole thread. I have now received two rolls from Maine Sail and the HD stuff will be used when I re-work my carport, not the boat!

There is a HUGE difference between the products. If I did not know they had the same base, I would not believe it. The Home Depot stuff is more like plumber's putty. It will fill the gap but not take a whole lot of movement. When it is compressed, it does not stick and elongate like the stuff Maine Sail is selling when things are moved and pulled apart.

Maine Sail, you DE MAN! Thanks!

Have FUN!

Glad I could help!!!

As I have mentioned many times I tested over 40 products for over a year before bringing Bed-It Tape to the marine market. In fact I am still testing other manufacturers and products and am still in the search for a white or off white products that meets my standards... I think it is a needle in a haystack but I keep trying. Was just sent a sample last week of a "new formulation" and sure enough it was new but still no good....

Glad you liked it and always glad when I can help...

Yep I went through the exact same process. I tried ebay and found something that's close. And then I tried McMaster and bought "Stay-Soft Glazing Rope":

"Easy to apply, this butyl rope seals leaks in ridges, eaves, gutters, and headers. Also holds glass in frames for a weather-tight seal. To use, uncurl rope and press in place. It stays soft and pliable for years. Application temperature range is –40 to +95 F; operating temperature range is –40 to +212 F. Diameter is 1/4". Comes in 20-ft. roll. Color is gray. This product is compliant under all state VOC rules in effect on October 1, 2008."

It's also close. But it never quite felt like how it was described here. So finally I bought some from Maine. His tape is softer, stickier, and comes in a nice thin tape form instead of round.

This stuff is similar to epoxy in that it all has the same base but still has be formulated just right for specific applications. A lot of variations are close but not quite the same. Maine is doing the work of sorting through that and selecting just the right thing.

So I strongly suggest everyone reading this thread buy from him and save themselves the time, trouble and money of working with the wrong thing.

I'm almost certain it's the correct stuff after reading this whole thread.

Thanks for the great tutorial. As a new, first time sailboat owner I really appreciate having detailed and illustrated instructions to use.
