1. They Release Harmful Toxins Into the Air
We've said it before , and we'll say it again. Standard wall mending agents contain a plethora of harmful toxins that pose immediate and long-term health risks. Commonly-found mending agent chemicals like ethyl acetate, xylene, and formaldehyde can cause irritation to the eyes and throat, nausea, headache, dizziness, anemia, and life-long respiratory issues from mere inhalation.
When you're tackling wall projects, particularly in confined indoor spaces, there are no two ways about it: you're breathing these toxins in.
2. They Leave You at Risk for Mold
A lot of the standard mending agents on the market are not waterproof, which means they become breeding grounds for dangerous mold . Even if you do find other mending agents purporting to be 100% waterproof, they tend to shrink a lot over the drying process — meaning air pockets will begin to emerge in cracks you once filled. Whether they appear in an exterior wall with exposure to rain and snow, a bathroom wall prone to settled moisture, or another part of the house where there's an undiagnosed leak, these gaps in your drywall provide an ideal environment for mold to take over.
It puts your family at risk of nasal and eye irritation, wheezing and coughing, fever, shortness of breath, and chronic headaches. And it puts your home at risk of exorbitantly expensive structural damage.
3. They Force You to Re-do the Same Work Again and Again
The common shrinkage of most standard mending agents doesn't only create a dangerous environment for airborne mold contaminants. It also means that, if you'd like to avoid the obvious eye sore and less-obvious health risks of re-cracked walls, you'll need to re-do the very same repair job. You'll have to spend more money and more of your free time. And in the process of re-applying the agent, you'll be exposing your loved ones to the release of harmful, health-compromising toxins all over again.
At first glance, the inefficacy is an inconvenience. Upon further inspection, it's a mending agent shortcoming with potentially grave consequences.
