Abstract:
For wall coatings on both interior and exterior surfaces, numerous substances can be used to
improve aesthetics, protect against weathering, and provide practical advantages. These coatings
provide walls with resilience, water resistance, and aesthetic value while also functioning as a
layer of protection. The development of a natural surface coating made of plant extracts is critical
for long-term sustainability. A natural surface coating is an environmentally conscious alternative
to synthetic coatings. Our study prioritizes using plant extracts in the coatings to reduce harmful
effects associated with the current coating industry and as a reaction to the growing demand for
environmentally conscious products. Furthermore, it can boost local economic growth by using
resources, preserve traditional knowledge, and limit the usage of toxic chemicals. This holistic
approach promotes sustainability, environmental stewardship, health and safety, and cultural
preservation. The experimental emphasis of the research is on the production of a natural surface
coating utilizing wood apple (Limonia acidissima) gum and other natural extracts. The methods
included coating formulation, testing, and application, as well as determining the best extraction
technique for wood apple gum. There were four treatments in the study such as 20%, 50%, 60%,
and 80% of wood apple gum with Dorana (Dipterocarpus glandulosus) oil and Haldummala
(Trachylobium verrucosum), named as T1, T2, T3, and T4 respectively. This investigation explored
the complex properties of coatings, looking closely at water resistance, viscosity, adhesion, pH
levels, and aesthetic appeal. From the study, it was identified that horizontal cut that was 100%
depth was the most effective technique to extract wood apple gum. The top-performing treatment
(T1) obtained a level 5B rating in adhesion and it exhibited ideal pH ranges and viscosities
comparable to those of available wall coatings in the market. Furthermore, T1 showed the
maximum hardness level (8H), while all treatments showed promising signs of water resistance.
The findings of this study may have a substantial influence on several sectors through the
provision of environmentally friendly substitutes, reduction of environmental impact,
enhancement of public health and safety, promotion of innovation, creation of new business
opportunities, fulfilment of customer demands, and preservation of traditional values.
