House Painting Inciteful Answers
Not all exterior painters have the knowledge and understanding of the composition of paint. Therefore, most are not able to articulate and convey a clear understanding, in such a way that the average person can understand how paint works.
Having these small discussions could establish realistic expectations in relation to the durability of paint coatings. Here is a light discussion that may help!
An Overlooked Function of House Paint
When considering water-based paint durability, one must first understand that latex/acrylic paints are developed in such a way that enables finished paint coats to breathe.
But because it’s breathable, this doesn’t mean water-based paints are any less durable than oils. In fact, this design arguably helps the overall performance of the paint.
The Importance of Water Permeation
Oil paints don’t breathe as well as acrylic polymers. The permeation rate of paint is important. Moisture transfer is one of several reasons there has been such extensive research and development associated with acrylic paints in the past few decades.
Allowing water and gas vapors to pass through the paint film allows the painted material to dry and limits the chances of the paint blistering. The ability to transfer moisture is extremely important for brick and wood applications. But what does this all mean in terms of durability?
Allowing moisture to transfer also helps keep the paint stuck to the painted area. In simple terms, a good permeation rate helps improve overall adhesion.
We all love the look of a freshly painted house. Just through a change of color alone, exterior house painting can breathe new life into any new or older home. But why is paint a necessity?
House Paint Protection
Exterior house paint protects exterior surfaces from rain, sleet, snow, ice, sun/UV protection, and insects just to mention a few.
Needless to say, paint has a lot of requirements to properly protect our homes. Therefore, it would be safe to say that climate has a lot to do with how long paint will hold up on the exterior of your home. Is your home west facing?
UV & Dark Colors
The placement of the home in correlation to the sun is a factor when considering how much exposure your home will endure. The color of your home also has a lot to do with durability!
Darker colors absorb more heat. Also, darker colors require more colorant or (tint). The requirement of more tint allows less room in the container for other raw materials. Less volume of solids results in less durability and more frequent repaints.
The Initial Paint Job
Often overlooked, regardless of the paint quality, correct surface preparation is the most important part of any exterior painter’s responsibilities. If the surface is not prepped properly the paint coating will simply fail.
However, the original level of quality when the home was built and the previous painters both contribute to what you may view as a problematic paint job. Does your exterior often fail in random locations? Does this leave you feeling as if your home requires you to pay extra attention to potential touch-ups? Do you feel you are having to re-paint more frequently than expected?
These are just a few of many reasons it’s important to contract a (professional) house painter. It would have been ideal to have an outstanding exterior house painter from inception to the last repaint. But let’s be honest, builders don’t get paid a penny more whether they use cheap or great paint.
On the other hand, most homeowners don’t know enough about paint to know the difference. So, if you have already purchased the home you’re likely already facing low-level paint quality. However, hiring a professional painting contractor can help mitigate some of your current and potential problems.
Hiring Smart House Painters
By contracting someone with good preparation practices and that has outstanding product knowledge, it will without a shadow of a doubt be more cost-effective for you long-term.
In conclusion, make sure the exterior painting contractor that you hire can clearly articulate, thoroughly explain themselves and the reasons behind their product choices and approach.
