ABSTRACT
Water-based paints were formulated using polyvinyl alcohol as binder and applied on cement surface. The polyvinyl alcohol (PVA) was dissolved in cold water and the mixture stirred continuously at 80oC for 5hours until a homogenous solution was obtained. The solution obtained was highly viscous with a light amber colour. The paints were formulated using the PVA solution and subsequently, applied onto a flat cemented surface using a small hand brush. The viscosity and density of the paints were found to be ranged between 37-39 centipoises and1.02-1.09g/cm3,respectively. Series of test such as drying times, weathering and adhesion were successfully carried out. The formulated paints also recorded a very good light property of 7. The overall performances of the paints were found to be very good.
