Dicor over Surebond

[nosek]

My question:

If I want to float some Dicor over Surebond SB-140 will it stick ?
The Surebond was used to seal a Skylight replacement.

if surebond has silicone in it like I believe it does, no it won't stick to it.
Nothing sticks to silicone including silicone on top of silicone.
but you can try

According the their website, 140 is a butyl sealant. SDS does not show silicone.

Looking at the Dicor website, self-leveling dicor can be used over butyl, and is actually recommended. Just make sure you get the Dicor past hte edges of the Surebond.
