Exterior Painting: How Often Should You Paint Your House?
If you are like most people in Edmonton, your home will be your most valuable asset. To preserve its value over time and maintain its curb appeal and structural integrity, you have to protect it from the damaging effects of moisture and UV radiation. The best way to do this is through regular exterior painting.
If your house’s exterior shows cracking and peeling paint and you see signs of rot on your wood siding, know that you have waited too long to repaint it. By waiting too long to apply that fresh coat of paint, it also gets harder to prepare the surface for painting.
The question then is:
How Long Does Paint Last On The Exterior Of A House?
The generally agreed timeline for repainting your house’s exterior is 5 to 10 years. But the truth is there is no universal answer to this question. How long a paint job lasts depends on different factors, not least the quality of the previous paint job.
Importantly, though, every house is different. Different construction materials have different strengths as well as varying abilities to hold paint.
Wood weathers fast and, depending on conditions, may need to be repainted every three years. A solid surface like fiberboard can keep for up to 15 years before it has to be repainted, while a brick wall can last for 20 years before it needs a fresh coat of paint.
But what causes exterior paint to fade or deteriorate?
The climate and weather have a big part to play in how long exterior painting lasts. Harsher weather, marked by excessive moisture, high humidity, or too much sunlight will mean paint fades or deteriorates faster.
High humidity and excessive moisture all have damaging effects on wood siding. If either through cracks in the wood or other forms of damage the wood absorbs moisture. As the wood expands and contracts, the paint starts to crack and peel. Where the air is humid, the moisture will also cause the wood to rot.
In Edmonton, our winters are long and brutal. All that moisture means that wood siding in particular will need constant protection with paint.
How To Make Sure Exterior Paint Lasts The Longest
Climate and weather notwithstanding, how long you have to wait before you repaint your house’s exterior depends on the quality of the previous paint job. Doing the following can prolong that time:
Invest In A Good Quality Paint
The first point to consider is the type and quality of paint you choose. Acrylic paint does not fade as fast and has better moisture repelling qualities than PVC paint. Even then, opt for the premium quality paint as that is not only easier to work with but produces a better finish too.
That said, even the best paint will not last long enough or look as good if poorly applied. What happens before you start painting determines how well the paint adheres and looks after application:
Surface Preparation Is Key To A Smart, Lasting Finish
Ensure your surfaces are well prepared by treating all spots of mold, replacing sections of rotted wood, filling all holes and cracks in stucco, and sandblasting all cracked and peeled paint. For wooden exteriors, applying a primer first is a good way of ensuring the paint adheres well and produces a pristine finish.
You should aim for a surface that’s fairly smooth and dust-free. After scraping or sanding it is a good practice to powerwash the surface to remove all dust. Remember, though, that the surface has to be completely dry before you apply paint.
Of course, with exterior painting especially, the more coats you apply the better. Two coats are usually sufficient. But if you are applying a lighter paint colour over a dark one, you may need a third coat to achieve your desired colour.
The more coats there are means the paint does not age as fast. Speaking of that, light paint shades generally fade more slowly than intense, rich colours like orange and red.
For the actual painting, choose warm days so the paint dries well between coats. If it has rained overnight, it is best to wait a few days for your surface to completely dry.
Well Maintained Houses Do Not Need To Be Painted As Frequently
Your house’s exterior is exposed to all kinds of wear that it is not enough to paint and then wait 5 years before you give it any attention.
For the paint job to last, you have to constantly monitor and inspect for dampness, rot, mold, and insect damage. Repairing these early will minimize overall damage and mean your house maintains its looks for longer. It ensures you don’t have to repaint it as frequently.
Good preventive maintenance involves regularly washing off mold before it discolours and weakens the paint. As long as that protective paint film is intact, you can safely powerwash any dirt on your walls and ensure your house’s exterior maintains its looks for longer.
Choose A Licensed, Bonded And Insured Exterior Painting Contractor
Regularly repainting your house is an excellent way to prevent moisture damage and block out ultraviolet rays that weaken paint and causes it to fade. But what you do during and in-between paint jobs determines how frequently you have to repaint.
While repainting your house may seem like the perfect DIY project, you will get the best results by assigning the work to an experienced, licensed, and fully insured exterior painting contractor. This way you get get a predictable result, with a professional paint finish that endures even the toughest conditions.
