Caulking

Posted by Rob Lane on October 25, 2010 at 8:55pm in Pool Service Topics

I have tried Vulchem 116 and it bread loafed in response to moisture in the subgrade.

I have tried 100% silicone and it did not stand the test of time.

I have tired two part polysulfide and a bulk gun. It went down in 2008 and is now showing signs of single side loss of adhesion.

DOES A CAULK EXIST THAT CAN STAND A KANSAS WINTER????

    It should hold. Check the specs (I think you can find them on the site) to make sure, but that should be within spec.

    Thanks for responding.
    All of our decks slope to the outside at 1/4" per foot. Will the Sikaflex SL run down the slope?

    Sorry for arriving so late to the party, but give Sikaflex SL a try! It comes in quart sized tubes (it is a gun grade material) and is used on freeways and bridges quite a bit. Self leveling and very durable, not to mention already mixed (no 2 part issues!). I've only seen grey and tan, but that covers most applications that I come up against.

    Here's a link to the manufacturer: http://www.sikaconstruction.com/

    Good luck!

    That is what i thought you were trying to do. For the expansion joint on the deck we have always used Vulchem45SSL(Semi Self Leveling). We will clean out the joint, add either backer rod or sand to fill the large gaps, and then apply the vulchem. It is not a cheap product, but works very well and since it is semi self leveling, it makes for a very nice finished product when it is done properly. This joint will typically have to be redone after 5 years or so, but we have not found anything else that will last as long. We are in Cleveland Ohio so i would assume our winters are similar if not worse.
    For the line above the tile, we have used silicone as it sticks and will not run down. Like anything else it will need redone after 5 years or so, but we have not had any issues with short life on it.

    Typically, the joint behind the coping, the joint between deck sections, and just above the tile.
