Six Tips for Painting Window Trim

By bearing in mind a few simple tips when painting a window trim, you can avoid the risk of painting the window shut or simply of making a complete mess.

Tip 1 – Start Early

Because you will probably want to keep the windows open after the window trim has been painted, start the job as early as possible. This will enable you to keep them open for the longest time possible before nightfall.

Tip 2 – Protect the Glass

Before beginning any painting work, take some precautions to protect the glass pane so that it sustains no damage and/or paint marks. Masking tape placed along the edge of the window pane is the best method to use. If the adhesive is stronger than necessary for the task, try pressing it to your clothes before placing it against the glass. Make sure it is completely straight to prevent voids in the paintwork after the tape is removed.

Where masking tape is not available, soak some strips of newspaper in water before carefully pressing it against the glass, however, this method is unlikely to remain in place for more than one brushstroke.

If necessary, cover the window ledge with newspaper to protect it from errant drops of paint.

Tip 3 – Use the Correct Equipment

An angled sash paintbrush will allow you to reach into the corners of the window trim and prevent you from missing any spots. Make sure that the type of paint you use is suitable for the material that the window trim is made out of.

Tip 4 – Prepare the Surface

If the window trim has previously been painted or has an uneven surface for some other reason, you may want to take time to prep the surface to receive the paint. Depending on the material to be painted, it may be sufficient to make use of some fine sandpaper.

Tip #5 – Take Your Time

Though it is tempting to rush through any paint job, it is not a good idea to do so on a window trim if you want a clean and uniform finish. Avoid overloading the paintbrush so that you do not risk drip marks that dry and make up part of the end result. Keep a wet sponge handy to immediately remove any mistakes before they have a chance to dry.

Should you be painting the trim of a double-hung window, carefully lift out the removable sashes and paint these first. Leave them to dry (for at least 24 hours) while you paint the rest of the window.

Tip #6 – Consider Result

Be aware that paint is capable of acting as a very efficient substitute for glue! Avoid painting the window jamb if you know that there will not be sufficient time to allow it to dry properly. Consider the potential result and determine whether you will be concerned with a spot that is only seen when the window is open. The overall look of the window trim will not be affected if you fail to paint the jamb.
