When installed in accordance with Siniat installation guidelines, the finished surface of all Siniat plasterboard accepts most types of decorative finish: emulsion or oil based paints, stipples, enamels, textured coatings and wallpapers. Matt finishes give the best appearance; gloss or sheen finishes tend to highlight any surface irregularities, as will harsh or glancing light. In order to obtain the best finish to the walls, Siniat recommends the following: Lay down the nap of any scuffed areas using MastaFinish, MastaLite or MastaGlide jointing compounds. The surface should be free of dust and other foreign matter. Ensure that the joint treatment is thoroughly dry before applying the sealer. Always seal over jointed and unjointed areas. Use roller application for paint. Overworking of sealant coat on jointed areas may cause paint to lift. Roller application applies uniform texture over the entire surface. Use only the best quality paints and other finishes. Use of sealers or undercoats that are water-based is preferred to reduce the possibility of raising the paper linerboard nap. Lightly sand between coats if nap is raised. Apply finishes in strict accordance with manufacturers' instructions.
