Deck rubber turning bad

Hi all,
The black rubber between the planks of my deck is turning off.
In some places, it looks like the rubber is going down deeper in between the planks and make a crevasse.
In somme place the rubber is sticky like a chewing gum in the sun.
And everywhere, it leave black marks on your clothes or your finger if your rub it gently.
Does anyone know what can be done and what to do to avoid it in the future?

From How to Clean Teak - TeakDecking Systems

DO NOT USE CHLORINE BLEACH in an attempt to bleach the decks. Chlorine will attack most caulking products, turning them to goo.

The bond breaker is laid in the bottom of the channel.

Re: Deck rubber turning bad

If you elect to fix it yourself, a daunting task on anything larger than say a 7' 4" dinghy, which probably hasn't got any seamed decking, I recommend getting a powered caulking gun. I was in construction my entire life and had really strong hands, and had emptied thousands of tubes of adhesive and caulking, but when I reseamed part of my boat my hands ached from squeezing that particular caulking out. I ended up using an 18 volt Ryobi caulking gun, and still decided that some areas would last til the next owner and really didn't look too bad if you squinted a little.
