Paint has a variety of sheen, it can be latex or oil-based. But most people choose latex paint, because of its longevity and it’s easy to clean up. It is also fade resistant and it dries quickly. However, oil-based paint works great as priming for real wood moldings and trim because it protects the wood from stains and knots better than latex. Oil-based paint is more durable than latex but it dries longer. You also need to use turpentine or paint thinner for cleaning up.
You should also consider the sheen. Always remember that glossier the paints are easier to clean up. For areas with high traffic, like kitchen and playroom if you have kids, opt for high gloss sheen because you can easily wipe out the wall stains.
Semi-gloss which is considered as a common alternative to high gloss can also be a great fit for bathrooms and kitchen, it’s easier to wash out and it’s less shiny than. When it comes to price semi-gloss is cheaper than high gloss.
If you walls has a lot of dents and dings you can use a satin sheen because it’s really great in covering up. Don’t use a glossy paint for walls with dents and dings because it will just draw more attention to it. Satin finish is more appropriate for walls with pocks, divots, and scrapes because it draws the light in and tricks the eye into seeing a more even surface. Satin sheen have a satiny smooth finish and could also be used in kitchens, baths and hallways.
For walls with lots of imperfections, you should use a flat or matte paint. One coat is usually enough to help you get away with imperfections. But the downside of this type of sheen is that this doesn't go well with good cleaning and tends to show more dirt so this sheen works well with rooms that doesn’t get lots of fingerprints and dirt on them.
The most popular sheen is eggshell, can hide imperfections just like flat but eggshell is easier to wash, it’s also more durable and has a smoother texture. It seems to have best of both flat and glossy characteristics, so it recommended for most rooms.
Ceiling flats which is specially made for ceilings, this has extra spatter-resistant characteristic, this doesn’t have sheen and the best finish to hide surface imperfections.
