Will it reduce the shine which is what I'm hoping or not mix %26amp; be streaky or ???What happens when you mix semi gloss paint with flat or satin paint?
Yes it will adjust the sheen. Two considerations though:
It is non-linear. Adding one part of flat (5 sheen) to 10 parts of gloss (85 sheen) will produce something like a 60 sheen (semi-gloss to satin). If you add equal parts of 5 sheen to 85 sheen you will get about 20 sheen (not 45).
The flattener is in suspension and it takes a lot of shear to get it distributed. If you are going to do this, I'd highly suggest getting one of those little squirrel cage mixer and put it on your drill and mix very very well.
Also, if you are going to do this measure very carefully so you can replicate the formula should you need more.What happens when you mix semi gloss paint with flat or satin paint?
I'm sure it's fine, as long as it's the same base...you can't mix latex and oil, etc..you know this I'm sure.
You also want to make very very sure you mix enough paint to finish the room...AND leave enough leftover to stash away for future touchups or whatever. Because even if you try your best to duplicate today's recipe exactly, it would be amost impossible to get it perfect, and you won't be able to get more of that paint.
Probably will do exactly what you want. I would go for mixing it with the flat paint for that 'semi flat' almost semi gloss look.
why dont you mix it and find out! yes it will but it will also adjust the color a bit
yes it will reduce the shine only by proportion to what you mix. the only thing shinier for interior paint than semi-gloss is gloss. if you mix the lesser shine satin or flat, you will come up with a matte finish that can't be duplicated.
