A person holds a cigarette over an ashtray; behind are a smartphone, vaping device, and a partially visible laptop on a white surface.

If you’ve ever moved into a home or apartment previously occupied by a smoker, you know how pervasive and unpleasant the smell of cigarette smoke can be. One common question is whether simply painting the walls can eliminate this stubborn odor.

Unfortunately, the answer is a resounding “No,” especially if your home has drywall. Let’s explore why painting is insufficient and why Biosweep of Central Florida’s advanced odor removal technology is the best solution.

Why Painting Isn’t Enough

Drywall, a common material in most homes, acts like a sponge, absorbing cigarette smoke and its odors deep into its structure. This means the smell isn’t just on the surface; it’s embedded within the walls, and a coat of paint will only temporarily mask the smell.

Odor Penetration

Cigarette smoke contains tar and other residues that penetrate deeply into porous surfaces. Even if you use multiple coats of paint, these residues can still release odors over time as they continue to seep out from within the walls. You can often see and feel how much tar is built up on the surface. If your property has had a heavy smoker for decades, there could even be a sticky substance on the walls.

Surface Sealing Issues

Paint alone often lacks the sealing properties needed to block odors completely. While specialized primers like shellac-based products can help somewhat, they are not foolproof and can be labor-intensive and costly.

Comprehensive Contamination

Cigarette smoke doesn’t just affect the walls. It infiltrates ceilings, floors, carpets, furniture, and HVAC systems. Painting addresses only one aspect of a larger problem, leaving many other surfaces untouched and still odorous.

Reactivation by Humidity

Environmental factors like humidity can reactivate trapped odors in painted walls, causing them to resurface. This means that even after painting, the smell can return under certain conditions.

Volatile Compounds Remain

Everyone knows that smoke stinks, but few know about the dangers of “thirdhand smoke”, which is compounds off-gassing from the buildup of cigarette smoke. According to researchers at San Diego State University, drywall contains gypsum, which is a sponge for volatile compounds (VOCs). These VOCs continue to leech into the atmosphere of the home even if you paint over the drywall.

The Superior Solution

For truly effective and lasting odor removal, Biosweep of Central Florida offers a cutting-edge solution: the photocatalytic oxidation process. Here’s why it works:

  1. Advanced Technology: Biosweep’s process uses powerful oxidation and hydroxyl radicals to break down and eliminate organic compounds, including those causing cigarette odor, at the molecular level. This is far more effective than surface-level treatments like painting.
  2. Comprehensive Treatment: The process treats the entire environment, not just the walls. It effectively removes odors from air ducts, carpets, furniture, and other materials where smoke residues have settled.
  3. Safe and Non-Toxic: Biosweep’s technology is safe for humans, pets, and the environment. Unlike some odor removal methods that use harsh chemicals, the photocatalytic oxidation process is non-toxic and eco-friendly.
  4. Permanent Results: Once treated, the odors do not return. The technology ensures that all smoke residues are fully broken down and neutralized, providing a permanent solution rather than a temporary fix.
