Abstract
This study was carried out to access the effect of gypsum plaster on the dry rate of emulsion paint. Gypsum plaster sourced from paint manufactures was added in presence of other raw materials to archive a better formulation. The pH the present product (8.4) falls within standard value of paints .The viscosity of the archived was 10 poise compared to that of standard products (8 poise). The dry time however recorded was 70 minutes compared to that of standard product which is usually 90 -110 minutes. These results underscore the need to further explore the use of gypsum plaster in the manufacture of paints considering its positive effects on the properties of paint especially in the reduction of the dry rate.
