Common Painting Problems
Failing paint on window frames is a very common problem.
The most common cause of peeling paint on window frames is the presence of moisture. Moisture can be introduced to a window frame by direct rainfall or condensation and will penetrate a painted surface several ways. It may enter through any crack in the paint, either through a joint that has not been properly sealed, through a crack in a window pane that has faulty putty, or through a gap between the siding and the window frame. Once water has penetrated the painted surface, it is naturally absorbed by the wood below. It will then expand and contract with temperature changes, and force the paint from the surface. When the wood is damp, the paint is “sitting” in the window sill and not “sticking,” as it should. Once the seal of the paint has been broken, moisture absorption will occur with every rainfall, repeating the cycle.
Another cause of peeling paint on window frames is a break down of the existing coat of paint. If paint failure is not caused by moisture, it will surely fail with age. Sunlight is a harsh enemy of a painted surface, with ultra-violet rays breaking down the protective resins in paint. The paint then cracks, eventually peeling from the surface exposing the bare wood exposed, which will eventually dry rot, or become “dozy.” A good test is to take a pencil, depress lightly on the wood; “dozy” wood is soft.
Regardless of the cause of paint break down, overtime the result is the same: rotten wood. If not repaired in time, failed paint will offer little or no protection to window frames, and the unprotected wood will eventually rot. Therefore, it is important to repair peeling paint as soon as possible. If left unattended, rotten wood can not be repaired. The deteriorated wood must be replaced, and this can be quite costly. Depending on the construction of your windows, sometimes the entire window must be replaced.
Fortunately, Student Works Painting can nip most wood rot problems in the bud, saving significant repair bills down the road.
Our crew begins by preparing all windows thoroughly, before applying any paint. The first step in this preparation is to scrape all loose paint from the window frames. We use long handled scrapers or, tough wire brushes, and plenty of elbow grease.
Once the loose paint is removed, we will sand the rough edges with 60 or 80 grit sandpaper in order to smooth them as much as possible. Marks may be noticeable when we are done, but they will not be pronounced. Once we have removed the loose paint and smoothed the surface, we will thoroughly wash the window frame. If at this time the wood is still damp from moisture, we may need to leave it for a day or two to dry.
Once dry, we will spot prime any bare wood. This seals the wood providing an ideal surface for adhesion of the finish coat. To avoid future moisture problems, all cracks and joints will be thoroughly caulked, and all failing putty will be removed and replaced. By attending to the preparation in this manner, we have ensured that all entry points for water have been sealed, and that future moisture problems are very unlikely.
Once these steps have been completed, we are ready to paint. It would be foolish to go to all this effort, and then apply a low quality paint, so our finish coat will be of the highest quality paint available. It will contain top quality resins and pigments, and have additives to prevent chalking, fading, mildew and fungal growth. If you are not changing colours, it is likely that one coat will be sufficient.
