TDS Deck Sealant is a one-part, paste-like neutral cure system which when exposed to moisture in the air reacts to form a tough, flexible solid rubber compound. The sealant is a thixotropic material, and when cured, has excellent temperature stability and chemical resistance. Because the sealant is neutral cure, it is non-corrosive to all substrates. No Primer Necessary.

Seams must be clean and dry. Surrounding wood should have 12% moisture content or less. DO NOT ATTEMPT TO CAULK WET SEAMS. Work under cover when possible, otherwise only open as much seam as can be cleaned and re-caulked in the same day. When caulking, the ambient temperature should be between 40-90°F (5-33° C). If it is too cold, caulking will not cure. In the tropics, the teak deck may become so hot from the sun that the uncured caulking will bubble out of the seams.

1) Seams must be thoroughly cleaned back to fresh wood. Old caulking can be removed with a razor knife and reefing hook, a router, or circular saw. After removing old caulk, sand the wood on sides of seams with a piece of 80-grit sandpaper. Remove any debris in seams with a reefing hook, a brush and a vacuum or compressed air. Be sure that compressed air system has traps for moisture and oil.

2) Thoroughly clean and de-oil teak in seams with clean rags dipped in acetone or Isopropyl alcohol. Change rags frequently. For best results, appropriate bond breaker tape should be applied to the bottom of a seam before caulking. (if joint depth greater than 8mm)

3) Do not use Primer ! To begin caulking, cut the top of the caulking nozzle to fit in the seam; and puncture the inner seal. Squeeze the end of the nozzle with a pair of pliers to allow the tip to reach the bottom of the seam. Apply SIS 440 to bottom of seam, allowing it to flow upward until crowning above the top of the seam. Smoothly pull the gun along the seam. Avoid starts and stops or changes in direction that may entrap air.

4) Immediately after application, draw a flexible putty knife over the seam at a 30° angle. Apply enough pressure to make sure caulking fills the bottom of seam and leaving the caulking a bit high to account for settling. Make sure seam has no entrapped air after application that could have entered the seam from the “starting and stopping process”, before continuing. The excess caulk can be sanded or carefully cut with a sharp chisel after the curing of the caulk has taken place.

5) Allow Black caulking to cure for at least 48 hours, for White and Grey caulking a minimum of a week in warm and tropical climates. In Europe and other colder climates it is recommended to wait at least 12 days before proceeding. When the caulking has cured remove excess with a sharp chisel or razor knife and sand surface of deck with 80-grit sandpaper. Note! 100-grit sandpaper or higher is recommended for White and Grey caulking, as to leave a smoother finish that traps less contaminants. Use a grinder with a soft pad. When sanding, hold surface of pad flat against the deck and keep it moving to avoid sanding a depression into the deck surface.

CAUTION: Wash thoroughly after handling. Wear protective gloves and eye protection. If on skin: Wash with plenty of soap and water. If skin irritation or rash occurs: Get medical advice/attention. If in eyes: Rinse cautiously with water for several minutes.
Remove contact lenses, if present and easy to do. If eye irritation persists: Get medical advice/attention. Take off contaminated clothing and wash it before reuse. Use with adequate ventilation. Avoid repeated and prolonged skin contact. Keep out of reach
of children. See SDS for first aid information. Dispose of contents/containers in accordance with local, regional, national and international regulations.

NOTE : Paint and varnish do not adhere to caulking. After sanding teak wood and caulking, be sure to thoroughly clean any surrounding surfaces that are to be painted with the appropriate solvent to remove any residue. Test surfaces before painting.

SHELF LIFE & STORAGE : Stored in a dry area at temperatures between 0°C - 26°C (32°-80° F) in the provided cases, the sealant has a shelf life of eighteen /18 months from the date of production. Note! Product date code on packaging is batch code and date of manufacture.
