JOINT EXPANSION It is recommended that dimensions be established for each joint in conformance with service conditions. Width of joint may be determined by calculating expansion and contraction of limits of the structure during temperature extremes and multiplying by a factor of 4. For example, if a joint will open and close 1/4" under temperature extremes, the joint should be designed 1/4" times 4, or 1" wide. No joint should be less than 1/4" wide.
INSTALLATION
PREPARATORY WORK The sealant bonding surfaces should be sound, clean and free of contamination such as release agents, water repellent treatment or other surface contaminants. Where adverse conditions are suspected, sanding is advisable.
METHOD OF APPLICATION Life-Calk can be applied directly from cartridges or bulk pails.
APPLICATION PROCEDURES 1. Clean joints and wash with Life-Calk Solvent and Cleaner.
2. Apply bond breaker.
3. Apply BoatLIFE Life-Calk Primer.
4. Apply Life-Calk with a hand or air operated caulking gun, putty knife or trowel, pushing cartridge away from you.
5. Tool seam.
CAUTION: DO NOT OPEN CONTAINER UNTIL READY TO USE
NOTE: It is important that the sealant be tooled to assure complete wetting of the bonding surface in order to obtain maximum adhesion. Care should be taken not to disturb the seal until completely cured.
CURE: Since Life-Calk sealant is a moisture/temperature cure and requires the absorption of moisture from the surrounding atmosphere, an increase in the relative humidity or submersion in water will result in a shorter tack free time and faster cure.
CLEANING OF EQUIPMENT: Wash equipment and tools with BoatLIFE Life-Calk Solvent and Cleaner or Release before material cures. TESTING IS RECOMMENDED.
Life-Calk is also paintable and sandable after complete curing occurs. Since curing time varies with the environment test a small area of the caulking. If the paint does not dry in a reasonable amount of time, a latex primer can be used. Do a second test of a small area.
*Note: Curing time will vary based on temperature, relative humidity, and age of product.
Tips:
To speed cure time, spray a little water onto one-part LIFE-CALK. To clean up tools, equipment and uncured LIFE-CALK use LIFE-CALK SOLVENT AND CLEANER or RELEASE. Push the caulking gun, do not pull it. In cold areas, warm tubes and cartridges before use. Fill in small cracks with LIQUID LIFE-CALK. Use LIFE-CALK PRIMER if there is any question about whether or not wood is oily (except with LIFE-CALK 2-part type P). Remove cured sealants with RELEASE by spraying edge of sealant. Work bonded area between surface and sealant with a scraping tool and RELEASE until sealant is weakened.
2013-03-29A shopper asked: I applied boat life cauking to a teak deck area. There was one aera that I missed full coverage can in just add a new bead to that area?

2013-03-29FREDERICK CARTER: Dear Boatlife Person,
Due to Boatlife pliability, I would be certain that this would work. Extend the bead to fully cover the bead that is in place, with several inches of new Boatlife to cover what has been done.
Happy Boating!

2012-08-27CATHY ROSENBERG asked: The clear caulk on our fiberglass boat has become moldy. How do i remove the caulk without damaging the fiberglass? And, what type of caulk is best to re-do it? Caulk line is above water line.
+Expand Answers
2012-08-28FREDERICK CARTER: Dear Cathy,
Not only do I use Boatlife on my boat but I use it, exclusively, in my home. I insist that plumbers not use their caulk but use mine, instead. I have set sinks, caulked windows, outdoor hose bibs, ect., with Boatlife.
The Boatlife solvent is also excellent. Last time I orderd the solvent, I ordered a case. I share with my friends. I would try that for the caulk removal. Use heavy gloves and a mask in tight places.
I would also have a multi-tool close by with the putty knife blade. I have a Sears Craftsman as I am unable to afford a Fein. The putty knife blade can be filed, extremely flat on the bottom, beveled on upper edge (be sure to de-burr). I think that holding the tool as flat as you can will help slice the old caulk away. It is the only method I have discovered to remove dried grout from ceramic tile, without damaging the tile. I hope some of this will help. Regards, Fred.
2012-08-31Cathy Rosenberg: Is the solvent safe for the gel coat on my fiberglass boat?
2012-08-31FREDERICK CARTER: Cathy,
I have never had any problems with fiberglass damage. I even use it when I want the fiberglass super clean. After your work is finished, wipe dry and then rinse with water. It will remove any wax that you had so reapply whatever you had on the surface.
Regards,
Fred
2012-08-29Cathy Rosenberg: So, the solvent will not damage the gel coat on the fiberglass boat?

2012-02-03DAVID BROWN: Before it is curred yes, but masking area and avoding "excess" material where you don't want it would be better.
2012-02-03WENDY BYAR: In the shop we have used paint thinner to clean up squeeze out. But its better not to get the sticky stuff spread around in the first place. Use masking tape on either side of the joint, scrape off the excess while the tape is in place, then peel up the tape. With luck you won't need furthur clean up.

2011-12-12A shopper asked: I have a large access plate on my swim platform that I have to remove to replace the bilge pump. Both the swim platform and the access plate are aluminum. Since it's awash alot of the time, I'm guessing I should be using an "under the waterline" product. And also one that allows me to remove the plate in the future if necessary. Is the Polysulfide suitable for this use?
2011-11-09KIM TOLAND asked: I need a diesel resistant caulk to repair the fuel tank on my boat. The fuel tanks made of laid fiber glass, in the bottom of the boat, with a steel plate lid with screws on 4 inch centers. I took the lid of to repair a leak and have not been able to get it to reseal. I see Boatlife Life-Calk is resistant to diesel. Do you think it is suitable for this application? Your assistance is greatly appreciated.
Thanks,
+Expand Answers
2011-11-09DONALD BEAUVAIS: It is all about preparation of the surfaces, In a well ventelated are use acetone to clan all the contact surface at least twice. Alpply the caulk to the leaky surfaces wait about 15 min. and reassemble and wait 24 hours for complete cure. Also remove the fuel tank to relieve any expansion pressure.
D. Beauvais
2011-11-09DAVID IRWIN: Its worth a try, but I would try cutting a sheet of gasket rubber first. The orange rubber reinforced nylon, You can buy it in small sheets at a Gung - Ho Hardware store or auto parts place. They might even sell a bedding compound to set it in that might be more suitable. Cut out a circle the size of the opening, cut the bolt holes into it and put it in place. Put the cover down on to of it and torque the nuts down on the cover. I'd run a bead of Boat Life or whatever bedding compound they recommend on both sides of your "rubber donut".
Good luck those can be nasty.

2011-11-09DREW DARLING: Hello Kim~
Don't have experience with Boat Life caulk and diesel. But one suggestion is to consider a great automotive product called Form-a-Gasket. It comes in a hand tube and is without doubt impervious to fuels and oils. Find it in an auto parts store.
2011-11-09MARK PELLERIN: I don't think Life Caulk will fix your problem. A lot of fibreglass tanks have been compromised and/or made obsolete by ethanol in gasoline and I assume your engine is diesel.... Nevertheless, fuel is a solvent .. fuel is a solvent.. fuel is a solvent.... did I say ..
This is the second tube (toothpaste-sized, not caulking-gun sized) of BoatLife products that opened up on me at the bottom, squirting stuff all over the place. The cause was using the little nozzle that comes with the tube. It restricts the flow enough to allow pressure to push the bottom open. This results in a huge mess and very difficult to apply material. They need to seal the bottoms better. Colgate learned that decades ago.

Comments about Boatlife Life-Calk:
To neatly apply, mask both the surrounding surface and the sides of the fitting being bedded. In the video, you'd apply masking tape to the teak rail and cut out the outline of the cleat base. Then mask the vertical edge of the cleat base. When the caulk is mostly cured, remove the tape for a nice neat job.
Be aware of silicone caulk when rebedding. Like every other caulk, BoatLife won't stick to silicone. If old silicone is present, it must be mechanically removed, or softened with a silicone digester and then removed. Even silicone won't stick to silicone.

Comments about Boatlife Life-Calk:
Purchased product because directions indicated the calk was paintable. Applied calk and after 8 days painted with 1 part polyurethane primer which would not dry. Called manufactor and after 3 tries, they finally confirmed the calk was not compatible with polyurethane paints. Would have saved me a lot of grief if they notated this on the label.

Works great for sealing a teak toerail. Thin enough to flow into small gaps and cracks. READ THE INSRUCTIONS. Use the primer for teak. I even applied boatlife caulk to a seam wet from a recent rain. It worked perfectly, and even cured faster.

This product was used to bond a plate to the transom for attaching transducers.. all 5 of them to a single plate. Great bond and seal..but very sticky and wear latex gloves as you will get it on everything. Much like applying silicon.. wet your finger before you flatten out the bead or your goint to have sticky fingers...

Comments about Boatlife Life-Calk:
The life calk I installed in mahogany deck joints failed after being exposed to sun and 85 degree temperatures. Failure involved separation from the wood and cracking of the material itself. After talking with the company, they diagnosed the problem: 1) I failed to add a bond breaking material at the bottom of the seam. The material can fail if it is stretched in three dimensions. 2) I did not remove all the varnish on the edge of the seam, and I did not use their solvent to assure a clean surface. 3) I may have left air pockets under the material at the bottom of the seam. I am probably going to try this material one more time in part because I can't find another one that is stretchy AND can be painted or varnished.Since this is a horizontal surface, I may try the liquid version because it may fill and level better and it may stick to the wood better.wish me luck!

Very sticky. Gets on everything if you aren't careful but makes a waterproof seal that can be removed when needed. This is more in the nature of a sealant, not an adhesive like 5200.
