For any interior and exterior paint job or paint maintenance project, it's important to determine how long the project will take before getting started. While certain elements may be predictable and help establish a specific timeline, a couple of unexpected factors could prolong the project. When figuring out the timeline of a paint maintenance project, the following are some key factors to consider.
Controllable elements impacting paint jobs
Some aspects of the paint job are under your control. These will be easy to quantify in terms of how they will affect the length of the project. Consider these factors:
Area to paint (m2)
The main factor to consider is the size of the area you'll need to paint. For instance, if you're painting most of a large multi-story building, this will likely take far longer than a smaller structure. Also, the larger the space, the more surface preparation you'll need to complete before painting.
Before starting any paint project, calculate the total area by multiplying the surface's width and height. Based on how long it takes to paint a single square metre, you can get a better idea of how long the project may take. A simple area calculator can help you figure out the space required.
Number of coats
The number of coats you need to apply will also affect the length of the project. The larger the surface area you need to paint, the longer it will take to apply a second coat or even more. Generally, it's best to use two coats of paint, which will double the amount of time it takes to apply the first coat. If you determine that you need to apply more, consider how each layer will multiply the total duration of the paint job.
Type of paint
The kind of paint you use will impact the total amount of time it takes to dry. In some cases, paint jobs may require a glossy and smooth look, in which case oil paint may be the best choice. Meanwhile, other projects may benefit from latex paint, which features low volatile organic compound (VOC) content and increased resistance to cracking.
Typically, oil paint takes around six to eight hours to dry, with another 24 hours required before you can apply a second coat. On the other hand, latex paints only take about an hour to dry, with no need to wait longer than four hours before applying the next coat.
In recent years, the concern for environmental sustainability has grown and as a result, many people are turning to using eco-friendly paint instead of traditional paint. Find out more about eco-friendly paint here.
The complexity of the surface
The surface texture you need to paint can greatly influence the total amount of time the project takes. For example, walls with popcorn textures and other textured surfaces will require more thorough painting than flatter surfaces. There may also be various structures to paint around, including piping and other protrusions.
In addition, you need to consider other areas, such as trim. These elements will often require a stain guard or primer to properly prepare.
Curing times
Another potentially controllable element is curing. It all depends on when you decide to paint the building's exterior. You may not be able to predict the weather, but you can take a look at the forecast and see if there will be rain. If you don't expect rain for around a full day after painting, the paint should have enough time to cure. You should also try to paint when it's not too humid, considering this could further prolong the curing process.
Of course, curing time will also depend on the paint you use for the paint job. For example, acrylic and latex paints don't take as long to cure as oil paints.
Uncontrollable elements impacting paint jobs
You may be able to control some of the factors that affect the timeline of a paint maintenance project. But you may need to adapt to a couple of unexpected elements. These uncontrollable factors could include:
The environment
Depending on the location of the building and the environment, weather and other conditions could impact project length. You may need to plan ahead for certain expected weather conditions, but the weather is never entirely predictable. You might encounter heavy rain or storm conditions that prevent you from being able to complete the project for a certain amount of time. These elements may also cause damage to newly applied paint surfaces, requiring you to apply additional coats.
Unforeseen repair requirements
Even if you inspect the surface area before painting, you may encounter unanticipated repair issues during paint maintenance. You may discover underlying damage behind walls, for instance, which would require more structural integrity work before you can apply a new layer of paint.
Take all major factors into account before starting your paint job
Before beginning any paint maintenance project, you need to consider all the factors that can affect the project timeline. From the surface area and types of paint to the environment and potential weather, there are a myriad of elements that can affect the outcome. Be sure to consider each potential circumstance and plan accordingly. This will help ensure the paint job goes smoothly from start to finish.
