10oz Marine Caulk Cartridge, Black - Premium Quality - SIS440 - for Teak Deck Seams - Provides First Class Appearance - UV & Chemical Resistant, Non-Corrosive

I was very pleased with the way it filled the seam and sanded. I prefer it to others I have used.

good product.

That’s it

I find this caulk to perform very well on my teak deck. But prepare well! Clean out the old caulk, clean with acetone, lay down a slick tape on the bottom of the groove so that the caulk only sticks to the sides of the teak and then apply carefully with blue masking tape protecting the teak itself. The caulk should last for 5+ years if applied correctly. Looks very nice!

Only time I've had an issue with this product. Had a hard time with this tube from the start and at the end of the tube I found this rubbery mess.As I used most of the tube, I'm hesitant about asking for a refund but it is a 1/4 of a $32 tube.

I use this product to fill my teak deck seams. I have tried several different brands To do this including two part sealers & have found this to be the easiest to apply, long lasting, & looks good.

The best stuff out there. Just finished resealing the teak on my 41 ft sailboat and would not use anything else. Had to redo sections where I used a different sealant just one year earlier.

This product a must have for woody boater or for someone working with boat and deck.Used it first time on my new deck made for my pre-war Chris Craft, this for over five years ago and is still in great condition.
