본 발명은, 기재층과 상기 기재층의 편면에 적층한 실리콘점착층을 포함하는 실리콘복합 방오시트로서, 상기 기재층이 불소 수지로 구성되고, 상기 실리콘점착층이, 경도가 아스커C 경도계로 5 이하이며, 또한, 모르타르테스트피스에 대한 점착력이 5N/25mm 이상인 것이며, 상기 기재층의 표면 중, 상기 실리콘점착층을 적층한 측의 면의 반대측의 표면이 방오면인 것을 특징으로 하는 실리콘복합 방오시트이다. 이로 인해, 장기간 안정되게 방오성, 세정성, 세정용이성, 내마모성을 나타내고, 또한, 피착체에 용이하게 첩부하고, 피시공면의 깨짐이나 어긋남에 대해서도 추종가능한 실리콘복합 방오시트, 및 그것을 이용한 낙서방지 시공방법을 제공한다. The present invention is an anti-fouling silicone composite sheet including: a substrate layer containing a fluororesin; and a silicone adhesive layer stacked on one surface of the substrate layer, having a hardness of 5 or less as measured with an Asker C hardness tester, and having an adhesive force with respect to a mortar test piece of 5 N/25 mm or more, wherein the substrate layer has a surface on which the silicone adhesive layer is stacked and the other surface is an anti-fouling surface. By the above configuration, the present invention provides an anti-fouling silicone composite sheet capable of exhibiting anti-fouling performance, washability, easiness of washing, and wear resistance stably for a long period, easily attachable to an adherend, and conformable even to cracking and shifting on the application surface; and a method for performing a prevention of graffiti by using the anti-fouling silicone composite sheet.
