ATOMO - Zero VOC Sealer/Primer for Outdoor and Indoor Use by San Marco

I didn't use it

This might be good but I don't know because I didn't use it under the Marco Polo paint. It is more a sealer than a primer and it's very liquid and no grains in it ! I bought it per recomandations to the sales person but I end up using Marcotherm as a primer !

Worked as intended

Used twice under San Marco lime paint. One was on rough structolite (usg gypsum plaster) walls, and second on smooth sheetrock. Both worked well. As usual with Decora products, I get a lot more coverage than the literature suggests, making them far more economical.

Nice product 👌
