[SML] Tips for Painting a concrete stage floor

[Bill Conner]

I'd use PPG Breakthrough V50-410.  It's a black satin100% acrylic.  Follow
directions which are mostly cleaning.

Epoxy would probably be more durable, but touch up - like if they splatter
some scene paint - would not be easy.  One of the virtues of Breakthrough
is how well a spot touch up blends in. Though perhaps they will usually
build show floors over this and that could protect the epoxy from needing
frequent to.

I like satin because it looks clean from damp mopping or dust mop.  Flat
always seems to look dirty and streak, but it is a preference,
Breakthrough is available in flat as well.
