description A method for sealing a loss circulation zone of a subterranean well includes delivering a loss circulation product into a wellbore of the subterranean well. The loss circulation product has a solvent, a fibrous material, and a first reactant. The fibrous material traps the first reactant to form a porous cake across a fracture of the loss circulation zone. A second reactant is delivered into the wellbore of the subterranean well, the second reactant passes through the porous cake and reacts with the first reactant, reducing a porosity of the porous cake across the fracture so that the loss circulation product seals the loss circulation zone.
