Tech Spec Product Info User Generated Content
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.

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...

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.

      Comments about BoatLIFE Life-Calk:

      I used this on my Com-Pac 25 which has cherry wood on the cockpit cowlings under the winches. Water was getting under the wood through failed white caulking, so I scraped that out an put in BoatLife Caulk mahogany color. It was really easy to apply, not messy, easy to clean up, and a beautiful match for the cherry that had been protected with penetrating eppoxy and 6 coats of varnich. Very pleased!!

        Comments about BoatLIFE Life-Calk:

        Disappointed by lifespan of product. Will be looking at non-marine products for above waterline.
        Not sure if Lifecaulk's formula changed over the years. I have decided to use Lifeseal for rebedding my chain plates since the lifecaulk crumbled out from there as well as at the toe rail/hull connection. I used Lifeseal for solar vents and the seal was perfect. My dissatisfaction with Lifecaulk has also been echoed by other members of the boating community. However, it still may be diesel fuel proof.

              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.

                    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.
