Some practical interior painting advice can go a long way toward producing a high quality and aesthetically pleasing outcome. Whether you are planning to do some decorative interior painting or just freshen up a room, good painting techniques give you an edge.
Although architectural interior designs differ from one house to another, the fundamental steps to painting remain the same.
Paint masking and covering
Paint prep – surface preparation
Painting Tools – Application
The selection of tools for interior painting should be based upon the scope of the paint job and the method of paint application. Standard paint applicators include paint brushes, paint rollers and roller accessories, and spray equipment. Choices among sprayers include an airless sprayer, HVLP sprayer, or conventional air sprayer.

Interior Painting - application
There are many aspects of interior painting. You may be planning to paint all the rooms throughout the house or just a single element within a space. Painting a room is basically the same as painting all the individual parts of a room. Below is a list of components that represent a typical living space.
Painting interior walls

Here are some additional surfaces that are often painted.
Cutting-In and Rolling vs. Spray Painting
The most popular method for painting walls and ceilings is with a paint brush and roller. A paint brush gives you the ability to reach into corners that are not accessible with a paint roller, and paint precise lines. This is also known as cutting in paint. A paint roller offers an efficient way to apply paint to the greater part of the walls and ceilings. This relatively easy paint application offers some clear advantages over spray painting, for small and medium size projects. Brushing and rolling does not require extensive masking compared to spray painting. This method also uses smaller quantities of paint.
Spray painting has a definite advantage when painting over very rough and irregular surfaces, such as brick or heavy texture. It can also be a timesaver for large interior painting projects. For the accomplished painter, spray painting doors and trim can be a big timesaver.
Where to Start
The architectural features of a room as well as the method of paint application are things to consider when deciding whether to paint the walls and ceiling before the trim or to do it in the reverse order.
Painting woodwork (trim) is generally more time consuming than painting walls and ceilings. Much of the time, the paint product used for walls and ceilings is different than that used for trim and doors. In rooms with extensive trim detail, I prefer to paint the woodwork before painting the adjacent drywall or plaster. It is easier to cut -in the walls against the finished trim than it is to cut-in the trim against a finished wall.
A new coat of paint must be compatible with the existing coat of paint. This will ensure that the new paint coating performs the way it is intended to. One common example of paint incompatibility is water base paint applied atop existing oil base paint. This usually results in adhesion problems causing peeling and flaking.
Make sure to verify the existing coatings before you purchase your materials. If you cannot find the old paint in your storage area, perform an alcohol test. Moisten a corner of a clean rag with a small amount of denatured (rubbing) alcohol. Rub the damp rag on the old finish. If the existing paint is softened and some paint gets on the rag, it is a water base paint.
Interior Painting Tips:
If the budget will allow, try to use quality paints and paint applicators. Improved workability and coverage, results in a better outcome.
When applying paint, it is important to maintain a wet edge in order to avoid overlapping and thick brush marks. This can be difficult because of the fast dry time of many paints, especially water base paints. Thinning the paint slightly with the proper paint conditioner or thinning agent can make the difference. You generally do not want to thin most paints more than five percent by volume.
Always follow safe painting practices because safety comes first.
