Romabio Marmorino Venetian Plaster, Flat

Coverage: per 25KG size - Approximately 300 ft2 – 400 ft2 (per coat) depending on absorption and type of base. Marmorino Flat can be applied to directly to all interior walls surfaces composed of drywall, painted or non-painted, using an appropriate primer. Custom color tint matching is available.

STEP 1 - Primer Coat - Dilute BioGrip Medium primer with 30% water. On porous surfaces apply product abundantly so as to penetrate sufficiently to consolidate and bond correctly. On slightly porous surfaces apply product evenly as needed to cover surface completely, being careful not to leave voids or unpainted surfaces. Allow to dry for at least 8 – 12 hours before applying any type of finish paint or plaster product.

STEP 2 - 1st Coat - Apply Marmorino GF with a thin layer of product and cover entire surface and then remove excess by tilting trowel to approximately 30°. Once excess has been removed, smooth surface using a 30° angle, compressing plaster using the same angle, in arched trowel motions, with a forward and backward direction, to create a smooth surface as is possible and allow product to slightly set.

STEP 3 - 2nd Coat - Apply Marmorino Flat to prepared and properly cured base as indicated above for 1st coat, using a round edge trowel specially designed for fine plaster applications. Apply a thin layer of product and cover entire surface and then remove excess by tilting trowel to approximately 30°. Once excess has been removed, smooth surface using a 30° angle, compressing plaster using the same angle, in arched trowel motions, with a forward and backward direction, to create a smooth surface as is possible and allow product to slightly set. Then begin to compress setting coat of Marmorino, pushing gently with the weight of the trowel to create a perfectly smooth and flat surface. Only work it enough to achieve a relatively smooth and even surface. Maintain a clean trowel at all times during finishes. At the last phase of drying and finishing, using a 15 – 20° angle on the finish trowel; burnish the Marmorino surface to achieve the desired sheen and decorative effect. Typical time lapse for this product to set between initial application and final burnishing is 1 – 3 hours when applied to a Marmorino GF or natural stucco base, depending on heat, humidity and base coat absorbency. Once the 2nd coat has visibility dried, a 3rd coat can then be applied.

STEP 4 - 3rd Coat - Once Marmorino Flat has visibly dried, repeat the steps of the 2nd coat indicated above, applying less material than at the initial onset of applying and covering the surface. Apply only enough material as is necessary to cover surface and permit a very smooth and flat surface. Follow instructions indicated in Step 2 including the burnishing with the trowel to create a professional and traditional finish as is historically typical for Marmorino plasters.
