Can you add something to flat laytex paint to make it semi gloss?

i think the proper way to do this is have them mix it in for you at the paint store. other wise it wont be mixed right.

Glitter is about all you can do.

You can mix in a water based polyurethane to get a little gloss, for higher gloss paint a layer of the poly over the flat paint.
Paste floor wax over the flat gives a nice finish, hand rubbed gentle sheen, hard work though.
On any of the above experiment on a small preferable separate piece before you tackle the wall.
Why not just get the same color in a glossy?

@pekenoe it is a 15” X 18” area so for the sake of not purchasing a whole gallon, I purchased the sample size. I will have to try the paste floor wax. Thanks for the info.

@lynzeut You’re welcome, I used the floor wax on distressed furniture that I made, really nice feel. Not permanent though, will need to be waxed once in a while.

The craft paint at Walmart works good for small projects too, just needs a protective covering.

Let me know how it came out.

use lip gloss LOL

How did it come out @lynzeut ?
