I replaced my expansion joint this past weekend. I debated on Sikaflex, but used Vulkrem 45SSL instead. It comes in 4 different color options as well. It was a little bit more money (then Sikaflex), but it is a semi self leveling sealant vs a Full Self Leveling. It is advertised as being made for pool joints as well. Worked out great and flowed nicely from the caulk gun. It wasn't too runny, but I can't imagine how the Full Self leveling would have been if this is considered Semi Leveling. It leveled out perfectly everywhere. I found it online cheaper then a lot of other online retailers at Coastal Concrete. I had found some good reviews on this stuff and expecting it to last several years. I'm glad that back breaking job is finished, ha ha.
Pool mastic replacement. DIY or not

I'm curious as to how the Vulkrem has held up after a year? Looking at taking on this project myself in the coming weeks.
I am needing to do mine soon. Probably just go with some Sikaflex. How much did y'all buy? I probably have 100 linear feet I need to do. I know there are many factors but are we talking (5) or (20) 29 oz. tubes? It looks like previously it was filled with sand then sealed with sealant. I assume sand was used rather than backer rod due to the non-uniform shape of the flagstone. Anyone else filled with sand up to about half an inch then put sealant on top?
I have to replace mastic and have a very large pool approximate 160 linear feet how many tubes of Vilkrem would I have to purchase? I Believe its sand filled, should I get the backer rod before pouring. HELP 
Also, as long as we are reviving an older thread, how is everyone's mastic holding up? Vulkrem or Sikaflex?

Mine has broken down on 2 sides - but I didn't prep those sides as well as the first section I did. Plus, there is a bit of movement on those sides that are separating. I will be replacing it this next spring when the weather warms back up. I used Sikaflex...
I am not sure if I will use Sikaflex again or "upgrade" to the new deck-o-seal one part.

How viscous is the Sika self leveling stuff? I'm thinking of using it on hairline cracking in my deck. Very small 1/32" at most, but at least 5 or 6, 7 or 8 foot cracks. Deck is stained, the sandstone color would be close. Just ooze it in and sprinkle with sand?

I am not sure it would be able to fill a tiny hairline crack - it is a pretty light liquid, but I would look for a crack sealer for something smaller than 1/32".
