The demand for fresco and sgraffito resulted in Portable Fresco phenomenon. FrescoShop.com offers a variety of portable fresco & sgraffito panels as well as materials to prepare virtually any surface for plaster application. System, developed and refined by the Fresco School makes use of the “Isolating Primer”. ![](https://frescoshop.com/wp-content/uploads/2021/12/single-double-base-fresco-sgraffito-panel-DAIGRAM-500web-1-300x300.jpg) #### Isolating Primer: For **Isolating Primer Coat ([...more details](https://agents.frescoshop.com/what-is-isolating-primer-for-fresco-sgraffito-panels-boards-non-porous-surfaces))** use any thick commercial water based paint, preferably exterior (creates softer, flexible paint layer). Isolating Primer is used to seal wooden (plywood) fresco sgraffito panel prior to application of base plasters ([Fresco plasterGrip or Sgraffito Base and Grip, Arriccio Plaster with Fresco Plaster Weld](https://frescoshop.com/product-tag/plastergrip-adhesives/)). To fortify the adhesion of the base plasters, Isolating Primer can be textured. Texturing helps to mitigate possible adhesion inconsistencies caused by the use of random paint. Textured Isolating Primer (Rough Textured + Fine Textured) is also used to add texture to previously painted or non porous surfaces (drywall, previously painted stucco and plaster walls, etc.) **[Rough Textured](https://frescoshop.com/classic/aged-lime-putty-fresco-plaster/fresco-aggregates/rough-texturing-sand-for-isolating-primer/ "Rough Texturing Sand for Isolating Primer") Isolating Primer Coat**, must be followed with **[Fine Textured](https://frescoshop.com/classic/aged-lime-putty-fresco-plaster/fresco-aggregates/fine-texturing-silica-sand-quartz-sand-for-isolating-primer-90-mesh/ "Fine Texturing Silica Sand (Quartz Sand) for Isolating Primer, 90 mesh") Isolating Primer Coat**! --- #### General Directions: * A light weight plywood panel is painted with a coat of Isolating Primer (any water-based commercial exterior paint): ![fresco sgraffito panel with a coat of isolating primer](https://frescoshop.com/wp-content/uploads/2023/01/fresco-sgraffito-panel-painted-with-isolating-primer-coat-530web-300x235.jpg) * Followed with: **First\***, a coat of Rough Textured Isolating Primer – 3 parts of Isolating Primer with 1 part of [Rough Texturing Sand](https://agents.frescoshop.com/classic/aged-lime-putty-fresco-plaster/fresco-aggregates/rough-texturing-sand-for-isolating-primer) ![rough texture sand marble for isolating primer](https://frescoshop.com/wp-content/uploads/2023/01/rough-textured-marble-sand-for-isolating-primer-530web2-300x226.jpg) ![rough textured isolating primer application ](https://frescoshop.com/wp-content/uploads/2023/01/rough-textured-isolating-primer-application-pic-530web-300x226.jpg) | | | | **Second**, a coat of Fine Textured Isolating Primer – 3 parts of Isolating Primer with 1 part of [Fine Texturing Sand](https://agents.frescoshop.com/classic/aged-lime-putty-fresco-plaster/fresco-aggregates/fine-texturing-silica-sand-quartz-sand-for-isolating-primer-90-mesh) ![90 mesh quartz Sand for isolating primer texturing](https://frescoshop.com/wp-content/uploads/2023/01/fine-texture-sand-isolating-primer-fresco-530web-300x238.jpg)![Fine textured isolating primer](https://frescoshop.com/wp-content/uploads/2023/01/fine-textured-isolating-primer-fresco-530web-300x231.jpg) | | | | Rough and Fine Textured Isolating Primer applied and cured: ![Rough and Fine Textured Isolating Primer applied and cured](https://frescoshop.com/wp-content/uploads/2023/01/fine-textured-isolating-primer-over-rough-textured-isolating-primer-530web.jpg) **\***For a small panel you can skip Rough Textured Isolating Primer coat After Isolating Primer Coat(s) are fully cured (approximately 24 hours after the last coat is applied) the next step is [Fresco plasterGrip, or Sgraffito Base and Grip, or Arriccio Plaster with Fresco Plaster Weld](https://frescoshop.com/product-tag/plastergrip-adhesives/) #### Walls & Surfaces Traditional Lime Plastered walls are no longer common and, if exist, are usually already painted with commercial paint. Whenever a fresco is desired a false wall is built on top of the preexisting one. Building of such walls for fresco is often not possible or cost prohibitive. Textured Isolating Primer is an alternative solution to installation of fresco plaster directly over painted wall or ceiling surface as well as any other non-porous surface. NOTE: Although Textured Isolating Primer will aid to create a genuine buon fresco or sgraffito using any support (wall), [traditional fresco wall system](https://agents.frescoshop.com/fresco-plaster-coats) is always preferred! --- **More from frescoshop.com:** [browse products](https://agents.frescoshop.com/shop) · [categories](https://agents.frescoshop.com/categories) · [agent index](https://agents.frescoshop.com/llms.txt) Published by frescoshop.com.
