I been staring at paint samples for 6 months trying to find something that felt right for my dining room. A designer friend mentioned Venetian plaster and I ended up here. Matched it to BM White Dove and the result is unreal. It has like an added warmth that paint just doesn't replicate. Already ordering for the living room.

Used Grassello on a fireplace surround. First time working with plaster and the application guide was clear enough that I felt confident going in. Took two weekends but the result looks like something out of an Italian villa

The color matching to Sherwin-Williams is what sold me. I have the rest of my apartment in SW Accessible Beige and needed the accent wall to coordinate exactly. Matched it perfectly. The search feature in the color picker made it easy.

Beautiful product. Took me three tries to get the burnishing technique down on a test board before I touched the real wall, which I'd recommend to anyone. End result is stunning. Took off one star only because I wish the quart size had a clearer coverage estimate for my wall dimensions. The project planner helped once I found it.

I was nervous to spend this much on something I'd never used before but I ordered a quart to test first. Now I've done three walls. The color I picked (BM Pale Oak) looks completely different in morning light vs evening and I'm obsessed with it

Was having issues w the burnishing step but I called and the guy I talked to was really helpful. The result is really pretty though!

How to Apply

Application

Prepare the Surface

Clean, dry, and structurally sound. Remove loose material, oil, grease, and dust. Fill irregularities. Prime with Violante PRIMO STRATO. Allow to dry fully before proceeding.

First & Second Coats

Apply in thin even layers using natural strokes to avoid choppiness. Work in sections, keeping a wet edge to avoid lap marks. Allow each coat to dry before proceeding. No more than 2 coats in the first 12 hours.

Third Coat & Burnish

Apply the final coat very thinly in a similar style to coats 1 and 2. Once partially set, burnish with a clean stainless steel trowel using firm strokes from all directions. Burnishing intensity controls the final level of gloss.

Curing

Initial hardness develops in 24–48 hours. True final hardness is achieved through carbonation, as lime reabsorbs CO₂ from air. This natural process continues over several months.

Questions

Frequently Asked

GRASSELLO can absolutely be applied by a skilled DIYer. It does have a learning curve compared to regular paint. We recommend practicing on a sample board first, watching application videos, and starting with a low-visibility wall. For large, high-visibility projects or mirror-finish results, a professional applicator will deliver the best outcome.

Yes, priming is essential for adhesion. We recommend Violante PRIMO STRATO, our micro-granular anchor primer formulated specifically for lime plaster application. It creates a textured, bonded base that ensures the plaster locks to the substrate properly. Apply one coat and allow to dry fully before starting your first GRASSELLO coat.

Yes, with the right protection. Allow the plaster to cure for at least one week, then apply 2 coats of a Natural Stone Impregnator or water-based stone sealer. This creates a moisture-resistant surface suitable for bathrooms and wet areas. For direct shower walls with constant water contact, proper sealing is critical.

Properly applied lime plaster is one of the most durable wall finishes available. GRASSELLO actually hardens over time through carbonation, becoming more durable as it ages. With normal care, a well-applied GRASSELLO finish will last the lifetime of the building.

Yes, you can paint over GRASSELLO with standard interior paint once it has fully cured. You can also apply a new coat of GRASSELLO over an existing finish. If you want to change the tinted color, the easiest approach is to apply a fresh coat in the new color directly over the existing finish.

Small repairs can be made by feathering fresh GRASSELLO into the damaged area using the same technique as the original application. For best color matching, use product from the same production batch. New plaster will initially appear slightly lighter and will blend more naturally as it cures and ages alongside the existing finish.
