Embodiment 1

[0025] Table 1 is for the ease of removing graffiti falling on the surface layer, and expresses its effect according to different materials used for graffiti.

[0027] In this example, the surface layer formed by applying a water-repellent solvent-condensed silicone resin paint and the surface layer formed by applying acrylic polyurethane paint as a general weather-resistant finishing material were sprayed with a paint sprayer. The removability of the graffiti was evaluated after graffiti was applied with an oil-based marker pen, and the releasable layer formed of the releasable paint applied thereon was peeled off.

[0028] The removability of graffiti on the surface layer made of a water-repellent solvent-condensation silicone resin paint is good regardless of whether a paint sprayer o...

[0033] The results show that if the physical properties of the hardened peelable layer formed by the peelable paint are that the elongation rate is above 100% and the tensile strength is 100kg / cm 2 The above shows that the operability of removing scribbles is very good.

[0034] From the above, the present invention has the following effects.

[0035] In the present invention, a surface layer is first formed by a water-repellent solvent-condensed silicon...

Abstract

Provided is a method for conveniently removing scribbles from buildings without injuring its surface layer. A solvent condensation type silicone resin coating material having water repellency is applied through a primer layer onto the surface of a substrate of a structure to form a hardly bonding surface layer. Scribbles are then formed on the surface layer and a releasable coating material is applied thereonto to form a releasable layer. The releasable layer is peeled from the surface layer after curing the releasable layer to thereby remove the scribbles from the surface of the structure.

Description

technical field [0001] The invention relates to a new method for removing graffiti on the surface of buildings, such as the outer surfaces of road facilities such as piers and bridges, the inner surface of tunnels, the inner and outer surfaces of houses and buildings, and the surfaces of road auxiliary facilities such as pillars and guardrails. method. Background technique [0002] On the surface of the building, it is often graffitied by misbehaving people. They are usually scribbled with paint sprayers and oil-based markers. [0003] As a method of removing such scribbles, one of them is to wipe them off by wiping with a thinner-containing rag or the like. However, wiping off graffiti requires a lot of manpower and time, and it is very difficult to completely wipe off, and it is easy to scratch the surface layer. [0004] Therefore, recently, such a method has been proposed, that is, on the surface of a building, coatings for preventing graffiti are pre-coated to form a...
