The designated sheen of a paint is a good indicator of the stain resistance and washability of the paint. Most generally, the higher the gloss in a paint, the easier it is to clean. Therefore, a gloss paint is easier to clean than a semi-gloss paint.
Gloss paints are effective in kitchens, bathrooms, entrance ways and dining rooms. The gloss finish reflects light to brighten the area along with having a surface that is easy to clean. A child's bedroom, hallways, woodwork, playrooms and ceilings are good areas to use semi-gloss. The softer reflection of the light adds brightness but provides a more calming atmosphere.
If flaws exist in the wall surface, choose a semi-gloss paint over a gloss. Gloss paint reflects more light, thus causing any flaws in the surface to show more readily.
A misconception exists that many individuals feel the higher the gloss or sheen of a paint, the longer the paint will last. This is not true. The quality of the paint plays a very important role in the longevity of the painted area. A low-quality gloss paint is less durable than a high quality semi-gloss paint. It is also important to note that low quality gloss or semi-gloss paint adhere poorly to the walls and do not dry as hard. This complicates the way the walls are cleaned. Scrubbing too vigorously will cause the paint to separate and peel from the walls.
