Are you looking for more glamour in your home interior? Do you want what's new in décor with an elegant splash? Is your room painted a great color but needs more "wow"? If you answered "yes", then I'd recommend going with the revived trend for faux painted texture for your walls.
There are new patterns and techniques. And the paint companies have developed new products for a new look to the wall finishes. These are not like the faux finishes of the past. Think of this a liquid wallcovering.
Lots of metallic for richness. Tone-on-tone effects with color, shine and matte finish. There are smooth or brushed finishes with multi-layer. The look is luxury, sophistication, richness and glamour. The idea is to create fashionable, classic interiors with drama.
An ideal area for this is the entry which is the first impression of your home so make a statement. A powder room is a smaller space and faux finishes made the room special. I always like dining rooms to have a feeling of romance and a wall with dimension, pattern and shine helps to create this mood.
Unless you are a great DIYer, I'd recommend a professional painter who has a specialty with faux finishes to do this work for you. However, if you give it a try yourself, you or a painter can always paint over it successfully.
