The precautions for flexible filler construction are as follows:
Construction principle: first seam inside, then seam outside, first both sides, then middle. The construction base must be solid and dry. Before the flexible filler is filled, the concrete bonded with the flexible filler should be cleaned to ensure that it is dry and clean. Loose concrete on the surface of the joint can be removed with a wire brush or other methods, and all debris and stone chips in the joint groove can be removed. Apply adhesive to the surface of the jointed concrete, and the painted surface should be 20mm wider than the contact surface of the filler. When filling the filler, the filler should be stuffed into the tank in layers from the bottom to the top, and filled into the desired shape according to the design size. During the filling process, it should be hammered to ensure that there are no cracks and ups and downs on the surface of the filler. After the packing is completed, the packing should be sealed. For example, on a concrete surface under a rib on the edge of a convex joint, the adhesive should be brushed and leveled with a flexible filler. After the flexible filler is applied, it should be protected from mechanical operation. In addition, the following matters should be paid attention to when applying flexible fillers:
Make sure the interface is clean and dry. Ensure that the bond between the filler and between the filler and the concrete surface is compact. When the filler is pasted, it should be exhausted while pasting, so that the connection between the filler and the interface is a dense whole. Please note that the application considerations for flexible fillers may vary depending on the specific material and engineering requirements. Therefore, before carrying out the actual construction, the technical description and engineering requirements of the relevant materials should be read in detail, and the construction should be carried out under the guidance of professionals.
