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.
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.
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.
