The aim of this project work is to formulate and produce emulsion paint from local source, which can compete comfortably with the global raw materials for paint production. The major raw material was clay from Enyigba in Abakaliki, Ebonyi State, Nigeria. Other ingredients used were: Water, titanium (iv) oxide, calcium carbonate, kaoline, combizel, P.V.A or acrylic, ammonia, deformer, genippor and formalin. The clay in Enyigba was carefully dug out and physically cleaned. It was then grinded and soaked in water for three days for softening. This was followed by calcinations for four hours at 750°C. The calcined clay was sieved to 0.02 um particle size and further cleaned up with tetra oxo sulphate (iv) acid, H₂SO₄. The prepared paint sample was characterized using standard methods as follows: Specific gravity (ASTMD 153-84): Refractive index (ASTMD 281-12): Oil absorption (AS TMD 281-12): PH (ASTMD 1208-90): And chemical composition determined via Energy Dispersive X-Ray Fluorescence Spectrometer (EDX-RF). The emulsion paint sample produced was subjected to quality control tests based on the Standard Organization of Nigeria, (SON) and was certified correct of the following properties: Colour, hiding power, viscosity, density, cracking, drying time and PH test. It is obvious that Enyigba has a raw material (clay) capable of producing world class emulsion paint with specific gravity, PH and oil absorption of 2.46, 6.67 and 34.30 g/g respectively.
