Performance improvement of cement-coated wood products with interface binding agents

A multi-layered fire-resistant lignocellulosic panel, comprising:

• a first layer, wherein the first layer comprises a lignocellulosic substrate;
• a second layer wherein the second layer comprises a cementitious binding agent slurry, the cementitious binding agent slurry comprising:
• a cementitious fire-resistant coating and an interface binding agent,
• the interface binding agent comprising a silane, a siliconate, an alkali silicate, or a combination thereof.

A method of creating a lignocellulosic panel with a cementitious coating that is resistant to delamination, the method comprising:

• depositing an interface binding layer onto at least one surface of the lignocellulosic panel, the interface binding layer comprising an interface binding agent and the interface binding agent comprising a silane, a siliconate, an alkali silicate, or a combination thereof;
• depositing a cementitious coating layer over the interface binding layer such that the interface binding layer is disposed between the cementitious coating layer and the lignocellulosic panel;
• and
• permitting the cementitious coating layer to cure onto the lignocellulosic panel.
