石膏用黏合底漆

I was nervous about getting plaster to stick to my smooth interior wall, but this primer grabbed onto the surface immediately. The mineral-based formula with aggregates gives it a nice tooth for the topcoat.

The mineral-based formula grabs onto the wall so well that I didn't have to worry about the plaster slipping off, even on the exterior patch I did. Coverage was solid in one coat, which saved me a ton of time before my color coat went on.

Went on thicker than I expected thanks to the high-solids mineral formula, and the aggregate texture gave my plaster something real to grab onto. Two coats over bare drywall and I haven't seen a single blister or peel.
