Why Preparation Is as Important as the Paint You Choose

Why Preparation Is as Important as the Paint You Choose

Paint failure isn't something anyone wants. But interior painting, exterior painting, or HOA painting all have their fair share. Not every factor that could affect paint performance is within our control, but we notice three critical issues behind paint problems over and over again. Here's what they are and how local house painters like Trico Painting avoid them.

Improper or Incomplete Surface Preparation

Painting is more than an art; it's a science. For proof, look at surface preparation. According to ScienceDirect, "Surface preparation cleans the adherend surface and/or introduces chemical functional groups at the surface to promote wetting and chemical bonding between the adherend and the adhesive. Contaminants include grease, dust, and oil; metal surfaces also become contaminated with oxides generated by corrosion."

In other words, surface preparation makes chemical reactions between paints/stains and the primed surface they're applied to possible so that the paints can stick to the primer, the primer can stick to the surface, and one coat of paint or finish can stick to another. Without proper preparation of the base surface (also known as the substrate), the whole process is degraded from the start.

Surface preparation includes the following steps:

  • Removing any old paint or stains from the surface: failure to do this can lead to paint bubbling or blistering.

  • Cleaning any dirt, dust, debris, mold, mildew, or other contaminants from the surface Inside, this can be done with professional-grade cleaners trusted by interior painting contractors. For exteriors, pressure washing services make the whole process more efficient and effective.

  • Removing wood rot: Wood rot removal from anywhere where wood is crumbling, cracking, or giving off a damp, musty smell is critical since you don't want it to spread and cause further damage to your property.

  • Repairing surface damage: Smoothing surfaces with dents and dings, or replacing any rotted boards or beams, will improve your finish dramatically.

  • Letting surfaces dry: This comes into play during surface prep and during primer, paint, and stain application too. Complete drying is necessary to ensure that paint looks its best (and performs its best) as soon as it goes on the surface.

Skipping any of these steps will compromise the appearance of your paint. Taking the time necessary for best results will help your paints protect your home's interior or exterior for years to come.

Mismatching the Paint to the Area and/or Surface Type

Just like surface preparation, choosing the correct paints and primers for your project is a science. In theory, it's not impossible to use interior paint on exterior surfaces, but we don't advise taking that risk. Simply put, match the paint type to the area you're painting. Don't use interior paint outside since it creates far more problems than it solves.

  • Interior paints can't withstand rain, snow, wind, UV, mildew, or temperature extremes, so they're not going to protect your exterior surfaces effectively.

  • Interior paint has less pigment and fewer binding resins than exterior paint, which means proper adherence to the surface will be a challenge.

  • Interior paint finishes are also too porous to perform well and have the impact exterior paints would on the same surface.

Similarly, it's not a good idea to use exterior paints inside. These paints contain mildewcides and are not designed for interior use. In fact, they can cause respiratory problems. The higher volume of acrylics in these paints can cause a lingering odor, which is unpleasant in interior spaces.

As you might expect, the chemistry of paints for various surfaces is specifically engineered to coat and stick to those surfaces. When looking for paints for your next painting project, check the surfaces they're designed for to ensure you have a good fit.
