토벽화 마감층은 채색층을 지지하는 벽체 층위로서 벽화 보존에 직접적으로 관련된 중요한 층위이다. 이는 주재료인 토양에 섬유 보강제, 보강 매제 등이 혼합되어 제작되며, 이 중 보강 매제는 물성 및 내구성 향상을 위한 것으로 문헌자료에 따르면 전통적으로 사용되던 아교, 풀 등의 천연 유기 접착제가 주를 이룬다. 매제의 사용 조건은 흙 반죽(plaster)의 작업성(workability)에 직접적인 영향을 주며 나아가 마감층과 벽화의 효과적인 조성과 내구성에 영향을 미치는 중요한 요소이다. 그러나 보강 매제의 사용법과 관련한 전통기술은 일제강점기와 근대화를 거치며 단절되어 현대의 문화재 수리보수 및 보존처리에 전통기술이 충분히 적용되는데 어려움이 있는 실정이다. 또한 관련 연구가 벽체 제작을 위한 토양의 종류 및 배합비율에 집중되어 있어 보강 매제를 중심으로 한 연구가 매우 적고, 대부분이 제작 후 물성만을 평가하고 있어 작업성을 평가하고자 하는 시도가 없었다.
따라서 본 연구에서는 전통적으로 토벽화 마감층 제작에 사용된 것으로 여겨지는 천연 보강 매제인 아교, 전분풀, 도박풀을 3%, 5%, 7%, 10% 농도로 적용하여 제작특성을 평가하였다. 특히 매제의 조건에 따라 흙 반죽의 작업성부터 완성된 마감층의 물성 및 내후성까지 전반적으로 평가하여 이에 관련한 자료를 확보하였다.
연구 결과, 토벽화 마감층 제작에 있어 보강 매제의 종류 뿐 아니라 농도에 따라서도 전반적으로 차이가 뚜렷하였으며 그 내용을 확인할 수 있었다. 매제의 점도와 흙 반죽의 작업성 사이에는 상관관계를 보이지 않았으며, 매제의 배합에 의해 세립질 토양 입자의 응집 양상에 차이가 발생하였다. 응집 양상은 종류에 따라서도 차이를 보였다.
아교를 배합한 흙 반죽은 농도가 높을수록 건조하고 쉽게 부서지는 등 작업성이 매우 떨어져 마감층 제작에 불리하였으며, 작업성의 저하로 인해 완성된 마감층의 강도가 보강 매제를 배합하지 않은 경우보다 낮았다. 다만 저농도의 아교를 배합할 경우 매끄러운 표면을 얻을 수 있었으며, 동결융해 작용 후에도 표면 열화가 나타나지 않아 표면 안정성이 매우 높았다. 따라서 아교는 3% 이하의 저농도에서 보강 매제로 사용되었을 가능성이 있으며 이를 평가하기 위한 추가적인 연구가 필요하다.
전분풀은 흙 반죽의 유연성이 높아지고 오래 유지되어 작업을 지속하기에 유리함을 가진 보강 매제였다. 또한 토양 입자가 치밀하게 제작되어 강도 보강의 효과도 뛰어났다. 그러나 7% 이상의 농도로 사용할 시 동결융해에 의해 표면에 얼룩이 진해지고 굴곡이 심하게 형성되는 등 표면 안정성이 떨어져 7% 이상의 농도로는 사용되지 않았을 것으로 보인다.
도박풀을 보강 매제로서 배합하면 작업성은 우수한 편이었으나 작업을 오래 지속하기에는 불리하였다. 전분풀과 마찬가지로 강도 보강의 효과가 있어 농도가 높아질수록 강도는 높아졌으나 5% 농도 이상에서 균열이 발생하여 벽화 조성이 어려운 건조양상을 보였다. 농도 3%의 경우에는 균열이 발생하지 않고 동결융해 후에도 표면이 안정하여 보강 매제로서 적합한 것으로 나타났다.
관련 기술의 단절로 연구자에 따라 해석에 차이를 보였던 토벽화 마감층 보강 매제에 대하여 본 연구를 통해, 아교, 전분풀, 도박풀을 보강 매제로 사용한 마감층의 특성을 규명하고 제작 방법에 대한 기초자료를 제공할 수 있었다. 이는 앞으로 토벽화 마감층의 전통기술 및 재료를 복원하고 보강 매제의 용법을 명확히 제시하는데 활용될 수 있을 것으로 기대된다.
