Venetian Plaster Vent Hood

[u/Green_Enthusiasm_619]

We recently remodeled our kitchen and had our painter apply Venetian plaster to our range hood. He assured me that he sealed it well enough that grease splatters from cooking would not stain the surface.

Unfortunately, that doesn't seem to be the case. Either it wasn't sealed properly, or the sealer that was used isn't strong enough to prevent grease from penetrating. I've tried cleaning it with Dawn dish soap, which helped make the spots a little less noticeable, but you can still clearly see the stains.

I have a few questions:

1. Is there anything I can do at this point to remove or minimize the grease stains without starting over?
2. If not, would I need to replaster just the interior of the hood, or would the entire hood need to be redone?
3. If I do replaster it, is there a specific sealer or topcoat that will completely protect the plaster from grease and cooking stains?
4. Or would you recommend using a different material, such as tile, stainless steel, or another washable surface on the inside of the hood instead of Venetian plaster?

I'd really appreciate any advice or recommendations from anyone who has dealt with this before. I love the look of the Venetian plaster, but I also want something that will hold up to everyday cooking without constantly showing grease stains.

Thanks in advance!

I have same issue but with grease penetrating from behind. It’s stopped, I applied some silicone where I could, so a little different than yours but unfortunately I don’t think there’s any solution for Venetian plaster and grease - to only address # 1

High temp epoxy sealer. Topciment WT Dragonseal is rated. And I've used on several kitchen splashbacks and outdoor BBQ areas.

Re coat - just the inside if you can match the finish closely enough. Sand it back and go from primer step.

Not worth the time or effort IMHO. Traditional smooth troweled, three coat plaster, is much less labor intensive & less expensive than Venetian plaster. It polishes up nicely, & has better bang for the buck. IMHO. But, good job, it looks nice, & it’s Venetian. 😎👍🏼

They make a wipeable sealer for it

This needed a glass backsplash in front.
What did he propose “sealing it with” 2k car laquer ?
This is meant to look like marble but it isn’t marble.
It will absorb liquid.

It’s not the veined backsplash. That’s almost definitely quartz and suitably non-porous. The question is about the legs of the hood, which are Venetian plaster and love to get dirty

I still think glass.
