If it were my pool deck, I'd install new wood. The Sikaflex is optional,
but it will make the wood last a few years longer.
The joints are there to control cracking, and if you fill them with
something solid, you might get cracks somewhere besides the bottom of
the joint. Hot weather can lead to cracking just as easily as cold
weather. Do you remember Texas freeways in the Sixties? The expansion
joints squeezed up in the summer heat and drove me crazy every summer.
"Ka-thump, ka-thump, ka-thump" for hours without a break. Unfortunately,
the expansion/contraction of concrete never stops, so you have to keep
the control joints forever.
I haven't used it, but many pools have a plastic spacer that fits the
joint. It looks kind of like Sikaflex, and it would be removable to
replace the underlying spacer, whatever you use.
