Are the parts pre-finished or what type of finishes can be applied?
A5: GRG (Glassfiber Reinforced Gypsum) and Plaster products are supplied unpainted for finishing after installation. Porviding that the correct primer is used, any latex or oil based finish can be applied. Due to the nature of gypsum or plaster, surface pinholes may appear. However, your Painting Contractor can fill these at the time of priming. High-gloss are not recommended unless your installing contractor also provides the desired level of surface preparation.
