Generally, a concrete impermeability tester is provided with a test mold, and before a concrete sample is pressed into the test mold of the impermeability tester, the important thing is to paint a sealing layer on the outer side surface of the concrete sample, and the purpose of painting the sealing layer is to completely seal the outer side surface of the concrete sample and the inner wall of the test mold, so that the marginal leakage phenomenon cannot occur in the process of detecting the applied water pressure.

The common methods for smearing the sealing layer in the test comprise paraffin sealing and cement-grease sealing, wherein the paraffin sealing refers to smearing a layer of molten paraffin with a small amount of rosin added in on the outer side surface of a concrete test piece, then pressing the test piece into a test mold preheated by an electric furnace or an oven by using a pressurizer to enable the test piece to be flush with the bottom of the test mold, and contacting the test mold with pressure after the test mold is cooled, and the preheating temperature of the test mold is determined by that the paraffin is slowly molten when contacting the test mold but does not flow. The cement and grease sealing means that a sealing material is uniformly coated on the outer side surface of a concrete test piece in a scraping mode by using a triangular knife, the thickness of the coating is 1-2 mm, then a test mold is sleeved on the coating, the test piece is pressed in, and the test piece is flush with the bottom of the test mold.
