A Study on the Development of Nature-friendly Water Repellents using Traditional Finishing Techniques

Abstract

By the analysis on the principle and effect of 'Kongdam,' (waxing the floor base sheets with ground beans) one of the traditional finishing methods, this study, which had intended to provide the fundamentals for the development of an environment-friendly water-repellent utilizing the traditional techniques in contrast with the other water-repellent used at present, received the following results. 1) In the experiment for the ratio of beans and water, it was difficult to apply 1:1 proportion due to the insufficient amount of water. It was possible to apply the 1:2 proportion on the base sheet of the earth finish, but there were some sticking to the surface. There was no sticking from the 1:3 proportion, and hardness increased. 2) Perilla Oil : For hardness in the experiment for the ratio of water, the values of surface hardness resulted up to 8H in all the proportions. For water permeation, the 40:60 proportion showed no penetration. 3) In the comparative experiment for hardness, water-repellent resulted lower than the original hwangto finish with the hardness value between 2B and 3B. The surface hardness of boiled linseed oil or bean oil resulted 3H or 4H, and the Kongdam resulted the highest(8H). 4) In the comparative experiment for water permeation, water-repellent allowed complete water penetration, similar to the case of the original hwangto. The boiled linseed oil and bean oil allowed penetration from 0.7cm to 2.4cm. For the case of Kongdam, it allowed penetration of 0.2~0.3㎝, which showed the best result. 5) It appears that the result is based on the lithification of protein in the bean water and the dryness of the perilla oil. And the water repelling capacity was more effective when only oil was applied on the earth finish. It seems the traditional technique of Kongdam has combined both principles properly. 6) There is a significance for Kongdam as a way to keep the tradition because it has been a Korean traditional technique to repel water, but also in a sense that it uses no chemical substance harmful for men, it is important to study the technique more in depth. To develop it further, many more experiments in terms of its performance as water-repellent should be carried out, and more studies on the traditional finishing techniques should be undertaken in the future.
