What a wonderful medium paint is! It is easy to apply with many shades and finishes. It is not expensive unless you choose to use an expensive brand (by the way I would recommend sticking in your budget) and it can be manipulated in many ways.
Here are 8 tips to think of when using paint:
When Choosing from a Swatch: Look for a color that appears slightly lighter and less strong than what you are seeking. When this color is applied to a large room it will reflect upon itself making it seem more intense.
When Matching a Color: Go to a color specialist. This is when you need someone who knows what they are doing.
When Thinking of Using White Paint: In an older property or in the use of an older person's home, white can seem to clinical and modern. Choose an off-white.
When Painting Woodwork: Consider using a satin or eggshell instead of gloss for a softer effect. In high traffic areas though, gloss is much easier to clean.
When Finding the Right Shade: Paint will always look darker when it dries.
When In Doubt, Try Another Color: If you hate it as it is going up, paint a small area. Sleep on it. If you still hate it in the morning, another color is necessary.
When Deciding on the Finish: Flat paint is never a good idea. Repeat, Flat paint is never a good idea. Even if you are trying to save money, spend the extra money now instead of later. Flat shows marks super quick and you will be super annoyed.
When Debating Another Coat: Just do it already.
