Common Mistakes People Make When Painting

A home or any other building looks totally different after the application of a fresh coat of paint. It’s why we all cringe when someone slightly dings or scuffs a relatively new paint job; however, as the damage is minor, more often than not, we shrug it away. However, bigger, bolder, and more conspicuous imperfections are difficult to ignore.

While knowing how to fix them is an admirable quality, it’s better to avoid making these errors altogether. Read on to discover some of the most common mistakes people make when painting and how to avoid reinventing an imperfect wheel.

Failure to Smoothen Out Old Paint

It is vital to prepare the surface you wish to paint before commencing the project. This is the key area where a lot of painting mistakes begin manifesting. After one has scraped away the loose, peeling, or flaking paint, the remaining section of old paint typically has some rough edges to it. These edges need to be sanded down as the new paint will spread out over them, creating a problematically thin coat.

In addition to getting rid of old peeling paint, if you’re painting on a glossy surface, ensure to scrape it off as well before giving your interior or exterior walls that new coat of paint. It presents a similar issue with the flaking coats, as the new coat of paint won’t have the best coverage, nor will it stick properly.

Neglecting Using a Primer

After failing to prepare the surface to be painted properly, failure to use a primer is the second most common mistake made by DIY homeowner painters. A well-done coat of primer will be of significant benefit to the external walls. It is doubly important to prime wood that hasn’t been painted before. Furthermore, unpainted wood surfaces exposed by peeling, flaking, scraping, or sanding during surface preparation, need a coat of primer.

Primers give you that sleek, durable finish as they cover up flaws within surfaces. If the walls or surfaces requiring the paintwork are in good shape, were previously painted, and have a flat but non-glossy finish, then it’s acceptable using paint-and-primer-in-one solutions. Painting over a difficult surface, however, will require you to use a premium all-in-one mix designed for unpainted surfaces or a stand-alone primer.

Applying Paint on Wet Surfaces

Painting on a wet surface is a common mistake that’ll end up costing you sooner rather than later. Painting exterior walls early in the morning when the dew is still clinging to the surfaces can cause you problems. So will painting after light showers, after power washing the house’s exterior and not giving it time to dry, or even painting too late in the evening when it’s cold and atmospheric moisture is condensing on the cool walls.

Moisture seeping from behind the surface to undergo painting presents a potential source of problems. It can result in peeling and blistering. Open seams at corner intersections and where doors and windows meet walls are the usual problem channels. For an easy fix, attentively caulk these areas. Siliconized acrylic caulk can also be used to seal cracks or splits in the siding. Ensure the caulk is paintable to prevent speedy erosion of the paint job.


Painting your own interiors and exteriors is practical and fun if you know of all the technicalities involved.
