Vasari Plaster & Stucco application is very simple even though there are many long explanations. Most people figure out how it works within 30 minutes just by playing around with the plaster on a few sample boards. You don't have to be a professional or an artist to get excellent results. After working with the plaster on a sample board or wall, you'll get a feel for it. One important thing to keep in mind is that the details of preparation can be as important as the plaster application itself. Simply follow the instructions below or watch our videos, and if any questions come up, please search our blogs, revisit our videos or email us. 

MARMORINO and STUCCO  Marmorino plaster is made with a fine sand, lime and crushed marble. It can have a soft, elegant finish with a light natural texture or more mottled with deeper texture and variation. It compliments both traditional and modern settings depending on how applied. Marmorino can be very durable, especially with a sealer or wax. We can make your plaster more durable by special request if going in very high traffic areas. Color combinations and creative styles are unlimited. Our plasters are very environmentally friendly, healthy and its qualities will improve with time.  Vasari's hypo-allergenic products will breath with your home absorbing moisture and naturally prevent mold or mildew growth.

STUCCO is very similar to Marmorino. The biggest diffference is that the Stucco has much more sand and larger aggregate than the Marmorino. This provides for more thickness, durability, and texture if desired. It can also be applied relatively smooth with minimal variation and texture. Because of this, it is more recommended for exteriors on larger scales. The proceeding application instructions are for for both the Stucco and Marmorino. The only real application difference is that Stucco will usually have a slightly longer drying time and will have about 20% less coverage than the Marmorino per bucket, as it is much thicker.



  • well primed new sheetrock with a high grade primer
  • previously existing latex paint (as long as it's not peeling off the wall)
  • well primed wood (or well primed anything)
  • unsealed cementatious coatings
  • unsealed concrete
  • cement boards, cement blocks, and most dense 'non-flakey' or dusty surfaces



  • floors
  • countertops
  • unprimed joint compound
  • raw sheetrock
  • pools
  • oil based surfaces
  • unprimed yeso

Marmorino is mostly used on interiors but can also be applied on exteriors. We recommend sealing it outside. You can even use it in shower stalls preferrably over a cement brown coat.



Depending on how you apply it, a 5 gallon bucket will cover about 100-120 square feet. That's both coats included. If you're going over previous heavy texture, you'lll get 80 square feet per 5 gallons. If you're doing it really thin and tight, you might get up to 150 square feet  or more per 5 gallons over a very smooth surface.



There are several brands of synthetic 'Venetian Plaster 'on the market commonly found in paint and home improvement stores. Our products are not comparable. Our plasters feel like real stone because it's made from stone. The other synthetic products feel synthetic, like plastic. There are lots of other natural wall finishes products out there. They all work a little different. So point is -- try to forget everything you ever learned about other products. We don't like using spatulas and tiny trowels to do large rooms. We don't like sanding all day to with fine sand paper to make it look like something.  If you're a contractor, like a drywaller, stucco guy or concrete finisher, please, forget what you know.  This is completely different...and easier.


If applying Marmorino on drywall, for new construction, drywall or gypsum board should be1/2" to 5/8" thick. This is standard thickness. The drywall should be taped at least at level 3 or 4 for Marmorino. If you're doing thicker coats, you can get away with level 2. This means there were three passes of joint compound on the tape joint. If you still don't understand - just don't have bumpy tape joint.  You can easily apply Marmorino as the final coat on top of cement brown coat. This can be a single coat or a double coat. Otherwise, over drywall, you will always do a minimum of 2 coats.

You can apply Marmorino over existing textures. Make sure that the wall (if doing interior) is well primed or well painted, When working with thicker than normal textures 

Any trim around the wall should ideally be stained, varnished, lacquered or finished already. The reason for this is that when trim is worked on; chances are the painter will stain the plaster or over spray lacquer, regardless of how well they mask it. This can leave a messy line between the wall and trim, especially if the plaster will be unsealed. It's harder to install trim on a textured / plastered wall.
