Stucco Romano

Technical characteristics STUCCO ROMANO is a natural lime based, decorative stucco that makes it possible to recreate a finish with an effect similar to marble. The special formulation of the product, made up of lime, selected marble powder and special additives, gives it an excellent adhesion to the support and a smooth flow in application making it easy and quick to achieve a perfect matt or gloss finish according to the desired effect. STUCCO ROMANO, thanks to its natural composition it guarantees the surface maximum levels of vapour permeability and aids the natural diffusion of humidity through plaster and brick work, thus avoiding the formation of mould and bacteria over time. The product has low odour, is non inflammable and is friendly to both humans and the environment. Ideal Use Decoration of interior walls and furnishings. Surface Preparation Clean the surface and apply a coat of the fixative IL PRIMER by OIKOS to insure perfect adhesion of the product to the surface. On rough and irregular surfaces, screed with STUCCO IN PASTA PER RASATURA by OIKOS. Application Method Warning: intense colours must be left to settle for approximately ten hours after being gìhaving been coloured in order to regain a suitable consistency. For an impeccable result, apply the product in three coats using the special Inox Steel Trowel by OIKOS. • First coat: proceed to screed the surface with STUCCO ROMANO. Wait 6 ÷ 8 hours until dry. • Second coat: proceed to apply a thin coat over the surface in such a way as to obtain a completely smooth but matt surface. Wait 6 ÷ 8 hours until dry. • Finish: for the best results, mix the product thoroughly before use to make it fluid, after this apply a thin coat of product, overlapping the trowel marks and at the same time polishing the surface with the blade of the trowel. According to the intensity of the polishing and the tool used in applying the finish, it is possible to obtain an end result with varying levels of gloss. Finishes To protect and enhance the sheen of the finish, after 6 ÷ 8 hours, apply CERA PER STUCCO by OIKOS. In the event that a greater level of impermeability and washability is desired apply PROTETTIVO PER STUCCO by OIKOS after 4 ÷ 5 days.
