Minimum seam requirements are 1/8" wide by 1/4" deep.

APPLICATION PROCEDURES

WOOD The surface must be dry, clean, and free of all old caulking materials. Cut back weathered surfaces or rot by routing, sanding, or sawing to solid wood. Rotted wood maybe treated with "Git"-Rot. When new wood is coated with preservatives such as Woodlife, the surface must be thoroughly sanded before application. We recommend a thorough washing with an oil free solvent such as BoatLIFE Life-Calk Solvent and Cleaner or pure acetone.

METAL The surface must be dry, clean, and free of corrosion, mill scales, rust, oil, paint, and all old caulking material. Remove corrosion by sandblasting, wire brushing, and grinding or chemical corrosion remover. Rusted surfaces may be treated with "Git"-Rust. When using chemical corrosion removers, thoroughly rinse away all traces of chemicals and thoroughly dry. Cleaning of corrosion-free metal may be accomplished with an oil-free solvent. When using an oil-free solvent (reclaimed solvents should not be used), a progressive cleaning procedure should be used. Wash a small area at a time, then dry with a clean cloth before the solvent evaporates to prevent contaminants on the surface. Always pour the solvent on the washing cloth to maintain a clean solvent supply.

SEAM FILLERS Where necessary, seams should be packed with BoatLIFE Bondbreaker standard caulking cotton, untreated jute, or some other compressible filler material. It is very important that seam fillers are not impregnated with oil or bituminous materials.

APPLICATION LIFE Application life is the period of time that the mixed compound remains at a consistency suitable for application with a spatula or caulking gun. Application life is always based on standard conditions of 75 F and 50% relative humidity. For every 10 F rise in temperature, the application life is reduced by half and for every 10 F drop, it is doubled. Higher humidity at the time of mixing shortens the application life.

CURE TIME Cure time, or the period of time required for the mixed compound to become firm and rubbery, is 72 hours at 75 F and 50% relative humidity. Variations in the rate of cure time may be due to temperature and humidity changes, since each 10 F increase in temperature above 75 F speeds the cure rate by 50% and each 10 F decrease in temperature slows the cure rate by 50%.

CLEANING OF EQUIPMENT Wash equipment and tools with BoatLIFE Life-Calk Solvent and Cleaner or acetone immediately after use or before material cures. Remove cured material by scraping, wire brushing and/or soaking in commercially available stripping compounds. Remove compound from hands by scrubbing with soap and stiff bristled brush.

HEALTH PRECAUTIONS BoatLIFE Life-Calk, Type P is proven to be safe material when handled with reasonable care. The sealant accelerator contains a lead compound. Avoid repeated or prolonged contact with the skin, especially contact with open breaks in the skin and ingestion. Always wash hands before eating or smoking.

          Comments about BoatLIFE Two-Part Life Calk:

          If mixed as the directions say - it is very difficult to use the entire qt before it goes off. I use a gram scale to meter out smaller quentities. The manufacturer needs to redesign the containers so that it is easier to remove the product

          Comments about BoatLIFE Two-Part Life Calk:

          Best to use is very cool weather. Should come with instructions to mix in small quantities as trying to mix and use the entire container at once is difficult to do before it goes off. That said the results are great and I am now going to use it on a 3rd boat.

            Best Uses

              Comments about BoatLIFE Two-Part Life Calk:

              Due to the short pot life it should be mixed in smaller quantities which is somewhat difficult as the amount of catalyst is very small. I use a digital gram scale to accurately measure the correct amount.
