Abstract

Polyvinyl acetate (PVAc) was synthesized from vinyl acetate monomer under atmospheric pressure and temperature of 72°C for three hours. Results obtained on the physico chemical analysis carried out on PVAc indicate that the specific gravity was 1.18, pH 4.2, density 1.25g/cm3, viscosity 0.40 centipoises, and refractive index 1.40. Comparison of these results with the literature values shows that physico chemical properties of the synthesized PVAc were in conformity. The PVAc was then used as a binder in the production of Trowel paint. The results of the physico-chemical analysis of the Trowel paint showed that the pH was 7.92, the specific gravity 2.3 and the hard drying time was 22 hours, which were also within range of the standard. The adhesion and opacity were excellent in line with the literature standard. The excellent covering power of this paint makes it to be used directly on non- plastered wall, thereby saving the cost of plastering
