Hello Stephanie,
As the acting C2C Care community monitor, I'd like to thank you for posting this question to the community. Lead consolidation is outside of my experience, so I will reach out to the community experts. In the meantime, I've gathered some resources, including past community discussions, and I'm hoping community members will be able to provide personal insights. Although the C2C Care program does not endorse any particular manufacturer or product, members are welcome to discuss lead sealant product experiences and recommendations.
Health & Safety for Museum Professionals, a joint publication from AIC and SPNHC, states water-based, low VOC paints are preferred for surface treatments, but they may contain potentially harmful additives (pg. 611). One of the lead sealant products I researched was a water-based, low VOC clear sealant that also contains glycol ether and bis(1,2,2,6,6-pentamethyl-4-piperidyl) sebacate (a biocide and curing agent).

Subject: Encapsulating wooden objected painted with lead paint
I have a piece of wooden wainscoting that has layers of lead paint that we want to preserve, but be able to show. What is an appropriate material to clear coat, but seal in the lead paint so the piece can be displayed without being a hazardous object?
Thanks!
Best,
