| Phase II • Pre-cast Concrete Deck Pate Preparation & Coating Application |
) Concrete Deck Plates For San Mateo Bridge Concrete deck plates have been sandblasted and are ready for application of PoxyPrime primer. The picture shows installation of PoxyPrime to deck plates by spray technicians. Because the deck plates lay horizontal, the PoxyPrime fills in all the bug holes, pin holes and holidays, eliminating the need for applying PoxyPrime BF. Once the primer has cured (slightly tacky), the deck plates are ready for application of the polyurea intermediate coat.
