（特開昭61−21762号）。 However, since this method is extremely inefficient, one of the inventors of the present invention conducted various studies to find a method for coating the epoxy resin coating material efficiently and with a good finish, and developed a method for applying the epoxy resin coating material efficiently and with a good finish. A method was invented in which a roller having a porous circumferential surface was used to impregnate the porous circumferential surface with water and then apply an epoxy resin coating material thereon (Japanese Patent Application Laid-open No. 21762/1983).

される。 The film thickness is not constant because it depends on the builder's sense.
Therefore, for example, in order to ensure a minimum film thickness of 3 mm, it is necessary to apply the film to an average thickness of 5 mm, which increases the amount of material used per unit area. The purpose of the present invention is to provide a method for efficiently applying an epoxy resin coating material to structures that are immersed in water or exposed to water splashes, and with a good finish.
A water-impregnated porous sheet is placed on the bottom plate of a formwork with a side frame placed on the bottom plate, and a water-curable solvent-free epoxy resin is placed on the porous sheet in the formwork. , flatten the porous layer of a roller having a porous layer on the outer peripheral surface using a roller impregnated with water, and remove the laminated sheet of the obtained porous sheet and an underwater curable solvent-free epoxy resin from the mold;
This is accomplished by pasting the resin side of this laminated sheet onto the surface of the object to be coated, and then removing the porous sheet.

It is placed and fixed on the bottom plate 3 so as to form a rectangular or square section.
型枠は側枠４で囲まれた枠の数が１個のもので

The size of the pipe 1 is preferably such that both ends of the pipe 1 protrude outside the side frame 4 when the pipe 1 is placed on the formwork, and the diameter is appropriately selected from a range of 5 to 10 cm. It will be done.

するのがよい。 As the porous layer 2, a foam made of vinyl chloride resin, polyurethane, polyethylene, natural rubber, etc. is used, and a soft foam is particularly preferable. If the thickness of the porous layer 2 is excessively thick, when the epoxy resin coating material is stretched to a uniform thickness, it will hit the side frame of the form and become dented, reducing the thickness of the film formed. It is preferable to set it to about 1 to 2 mm.

A porous sheet 5 inside the formwork
Then, the porous layer 2 on the outer circumferential surface of the pipe 1 is soaked with water, and the epoxy resin coating material is rolled and rolled from the front to the front so that it has a uniform thickness. Make it. The obtained laminated sheet (a layer of epoxy resin coating material laminated on the porous sheet 5) is removed from the mold, and the resin side of the laminated sheet is applied to the object to be coated. Next, the porous sheet 5 is peeled off and the epoxy resin coating remaining on the object to be coated is pressed onto the surface to be coated by hand or using a rotary roller whose porous layer has been hydrated as shown in FIGS. 5 to 8. In this case, the joint portion between the epoxy resin coatings is preliminarily applied with fingers (lightly swiveled 2 to 3 times).
