Yes, Eggshell and Satin are very similar. Though i would recommend scuffing the walls with a sanding block or sandpaper to help with adhesion . Also current and new colors will make a difference, you may need to use primer if applying a lighter color over a darker one or if there are excessive stains on the walls.
As both paints are latex based it is not absolutely necessary.
Satin has a high gloss than eggshell, so it wouldn't hurt is at least use a de-glossing wash (like TSP) before painting. Be sure to rinse well and allow to dry completely.
The condition of the old paint, its age and the colours you are using may directly effect the need for sanding & priming.
- If you need to patch or repair the surface then you SHOULD sand and prime the retouched area at the very least.
- If the surface is clean and in very good repair, the colours are close and the satin paint is old, it may be un-necessary to prime.
- If you are trying to cover a very dark colour with a light coloured paint then a prime coat will reduce the chance of the dark "showing through"
Yes, as long as the surface is free of dirt, wax and grease, and the eggshell and satin are both the same type, ie latex or oil, then you should have no trouble at all painting a satin sheen paint over an eggshell. Also, if the base is water based and the topcoat is oil, that will work fine too.
More important is, that both paints are of the same kind (like: oil-based paint, acrylic paint, latex paint). Semi-gloss is more easily painted over then high gloss, but first better find out what the old paint layer is made of. Check with the help of alcohol - if paint comes off in any way when you rub it with a cloth of alcohol, it's latex or acrylic paint (and can be painted over with acrylics).
I would recommed satin or eggshell. Satin and eggshell paint or both easy to wipe/clean and better to withstand multiple cleanings.
No, because eggshell paint is intended only for indoor use, like kitchens or bathrooms. For exteriors, use paint with a satin finish.
There are different kinds of satin paint - you'd have to know if it was latex, oil, enamel, alkyd etc.
Two entirely different things. Acrylic is a type of water-based paint (usually latex/acrylic) and eggshell refers to the sheen (ie flat, satin, eggshell, semi-gloss, etc...). Also some people assume eggshell refers to a certain color, however with many paint companies, the term "eggshell" refers to the sheen texture (feels like an egg shell) and not the color of an egg (which, of course, depends entirely on the type of bird if came from). :)
If you mix a flat and semi-gloss 1:1 you should end up with a paint in the eggshell range. Mix the same paints 1:3 and you should end up with a satin. Experiment with small amounts to get the desired gloss.
Yes, depending on the mix ratio, you will end up with an eggshell or satin finish.
The flat latex paint will stick to satin or semi-gloss latex paint without any problems. The main consern is making sure the surface is clean and sound before begining to paint, plus use top quality paints for the best results.
Yes or it can be the same as the wall paint if it should be flat.
Sure you can!it will work just fine
Many hotels that use paint use satin or semi-gloss latex paint in their interior applications.
