The present invention discloses a two-layer re-sticking process for a paper guard to assist in the restoration of old calligraphy and painting. The process uses a paper guard with a smooth surface to be moistened and then tightly applied to the back of the second layer of the painting core through the surface tension of water (commonly known as "water roots") as a support. The second layer of the painting core will be adsorbed on the paper guard as a whole, and the second layer of the painting core can be safely and losslessly lifted up and separated. The auxiliary paper carrying the first layer of the painting core and the protective paper adsorbed with the second layer of the painting core are sprayed with water to be soaked. When the two are swollen to the maximum size, the excess water is sucked out (commonly known as "pulling dry") to shape them. Then the protective paper and the auxiliary paper are cut into squares at the same time. The size of the painting core remains unchanged when sizing. It is ensured that the edges of the auxiliary paper and the protective paper guard completely overlap to achieve the accurate re-sticking of the first and second layers of the painting core of the sandwiched rice paper. The re-sticking process of the present invention not only solves the problem of the shell of the sandwiched rice paper painting core, but more importantly, the painting core does not suffer secondary damage, and the original rich color sense and solemn brushwork of the sandwiched rice paper painting are retained to the maximum extent, thereby extending the life of the calligraphy and painting.
