Question

I need to glue glass to glass, glass to porcelain and glass to metal. The glued up pieces will be outdoors year round in NE Pa. Will life-seal be a good glue for this type of application?

Jason: Thanks for the tip. The only problem I see with the 3M 5200 is that I can only find it in white or black. When I'm gluing up glass I need a clear adhesive. Thanks, Bill

Frederick: Thanks for your response. I think you are correct that the flex may be very important, especially when I'm joining glass to glass. Thanks again, Bill

Answered on 06/05/2013 by Bill Bauersfeld

Answer

Lifeseal will provide a good seal with mild to moderate adhesion; if strong adhesion is required then I would use 3M 5200 which is nearly permanent.

Answered on 06/08/2013 by JASON WALL

Answer

Bill, Wow! I've not tried the glass to glass, but as Boatlife remains pliable, I bet it would work. Your glass to glass may be cold outside, warm inside so the flex will be even more important. The other glue joints should be OK for the same reason. Regards ...

Answer

Bill, I think Life-seal will work very well for those applications. I use it seal Lexan to aluminum hatch frames, varnished wood, and painted fiberglass. It has held up for the last approximately 20 years. It failed once when I applied it in temperatures around 40 degrees F. Good luck,

Would you use lifeseal to seal the metal screws and holes that were screwed into an aluminum boat to hold on a bracket for a fish finder transducer?

Asked on 07/14/2011 by jim z

Top Answer

I used the lifeseal around the portlights I rebedded. If I need to seal something below the waterline I would use something like 3M adhesive sealant.

Jim, I would...Some paints might have difficulty painting over this product so check compatibility with the top coating you might be using or a required primer sealer before top coating is applied over the sealer. Harry

Answer

Addendum: The stainless would attack the aluminum as it is more noble, cationic, and there could be some corrosion of the aluminum. Disregard my comment about the stainless rusting as that was not accurate. Jason

Answered on 07/17/2011 by JASON WALL

Answer

Yes, BUT... You don't give very much information so I will make the assumption that this is an underwater application. ¥Ë_¥Ë_¥Ë_¥Ë_You say "metal" screws, but the type of metal is VERY important. ¥Ë_¥Ë_¥Ë_¥Ë_Although aluminum and stainless steel get along fine above the waterline, stainless steel should never be used underwater. ¥Ë_¥Ë_¥Ë_¥Ë_When it is, such as for prop shafts and trim tabs, notice that there is always a sacrificial anode attached to protect the stainless steel from corrosion. For an aluminum hull you should use aluminum fasteners. ¥Ë_¥Ë_¥Ë_¥Ë_If you can't find the correct aluminum fasteners you need for your application then use bronze. ¥Ë_¥Ë_¥Ë_¥Ë_However, when aluminum and bronze are in contact with each other underwater they form a galvanic cell and the aluminum corrodes. ¥Ë_¥Ë_¥Ë_¥Ë_If you use bronze fasteners you will need to completely electrically isolate them from your aluminum hull with plastic sleeves and washers (they are made just for this purpose). ¥Ë_¥Ë_¥Ë_¥Ë_But it is much easier and there is less potential for leaks to just use aluminum fasteners. ¥Ë_¥Ë_¥Ë_¥Ë_The same goes for your fish finder bracket - if it is not also aluminum then it too will need to be electrically isolated from your aluminum hull. I have used BoatLIFE Life-Seal both above and below the waterline as a sealant for various materials and am very satisfied with it. The tube does say that Life-Seal is for use with aluminum. ¥Ë_¥Ë_¥Ë_¥Ë_Be sure that your contact surfaces are clean clean clean! ¥Ë_¥Ë_¥Ë_¥Ë_You might want to roughen smooth contact surfaces with some 120 grit sandpaper. ¥Ë_¥Ë_¥Ë_¥Ë_Some people advocate further tightening fasteners after the sealant has cured - this is a bad idea as doing so has the potential to break the bond between the sealant and fastener, and at the very least puts it under stress and it may separate over time. ¥Ë_¥Ë_¥Ë_¥Ë_ I hope this answers your question.

Answer

For anything permanent at, under, or around the waterline I would only use polyurethane.

Answered on 07/18/2011 by ANDREW OMSTEAD

Answer

Yes, Boatlife Lifeseal can be used for bedding your fish finder bracket to the boat console and it will also seal the screws and holes.

I have used it outside & eventually mold forms on it. But, it can be cleaned. I do not know if any sealant truly prevents mold.

I have not had good success as of late regarding the mold/mildew resistance of BoatLIFE Lifeseal. For the first time in over 20 years I'm going to try a different product.

Answer

Tom, The BoatLife Lifeseal and Caulk are great products and I would use no other for caulking and seating. I have never used the BoatLife in your application. My opinion is that it is a sealant and not a glue. I would not use it for your application, unless you used an external reinforcement (larger diameter pipe) with clamps. Sorry I can do no better. Regards ...

Answered on 06/06/2012 by FREDERICK CARTER

Answer

The package says it adheres to "ABS and other plastics." So, I would think that it would adhere to PVC pipes. I use it around the house for any caulking that needs to be done, inside and outside. Works great for me. Another suggestion that I know for a fact works on PVC pipes is Mighty Putty (check Amazon for this). We had a PVC pipe in the basement that we no longer wanted connected. The plumber put a cap on it but it leaked water all the time, so I got the Mighty Putty and applied where the cap met the pipe and no more leaks.

Answered on 06/07/2012 by MARSHA PERKINSON

Answer

In my opinion, this is not an appropriate application for this product. This is a bedding compound intended to form a gasket-like sealing interface between two surfaces. It will not be successful in pthing a crack externally on a PVC substrate. Suggest sanding then applying a fiberglass tape wrap with next resin if replacement if the failed component is not feasible.

Question

Do you recommend life seal for caulking chainplates (metal to fiberglass)? Currntly using lifecaulk, but need to rebed every few years. Hoping for longer service without water incursion with lifeseal. A little worried about your descriptions of lifeseal not curing in a sealed environment, as chainplates are essentially sealed except at edges.

Asked on 08/31/2018 by Bill from Bainbridge Island, WA

Top Answer

Lifeseal should work for that, I used it in various "sealed environment" locations and it did cure the whole way through.

Answer

In my efforts to seal chainplates, I have tried Life Seal many times. It sticks to fiberglass but not stainless steel. Even after using an acid-etching primer, the bond to stainless failed. Three years ago I tried butyl rubber tape caulk which comes in strip form on a roll. It worked! All my chainplates are watertight for the first time in 25 years! I recommend that Jamestown Distributors carry it along with a How-To page describing its use for this purpose. It is now available at Defender Industries. Dennis

Will fresh life seal stick to cured life seal? After a lot of searching I used it to seal my sunroom - glass to aluminum. However I still have a small leak somewhere.

Question

I have restored bronze portlights and am preparing to re-install them. Previously, the exterior "trim/dressing" was teak...I have changed those dressings to starboard. Question: Will Lifeseal remain attached to the starboard? I feel it will adhere to the bronze without problem. There have been numerous leaks previously...I want them to stop!

Asked on 05/14/2013 by Drew Snillor

Top Answer

I haven't used this product for that specific purpose. However, I have used a lot of Lifeseal and do feel it is the best of all similar products. I am confident you will be happy with it. If I had any leaks, it's the first stuff I would try. Hope this helps.
