|
|
I am doing a repair to an existing bridge,
I am putting a telescoping crown over the metal framework of a bridge in a pontic area. essentially bonding metal to metal here.
What I want to do is sandblast crown and framework, sim 2 , both surfaces, cure and cement with anchor. I should not have to place an additional layer on uncured sim on either of these metal surfaces..Correct?
If I used Sur, instead, I should use cured sur 3 on each sandblasted surface and place anchor and seat. Also Correct? |

Why bother bonding?? What's the purpose?
I'd just cement with an RMGI like Fujicem. _________________ No, Donny, these men are nihilists, there's nothing to be afraid of.... |

No. It could still work, but no it will not be as strong. _________________ "You need me on that wall."
