It's the cleanup.
I hate it. It's the worst.
And, I could just as easily buy throw-away stuff, but that goes against my principles. Which, of course, is why corners of my house are cluttered. Brutal.
At any rate, I finally wrap my mind around getting the project done. Calculations of square footage are done, sanding and scraping are done, gathering supplies, and finally buying the paint.
While sanding and scraping, I realized - why am I not wearing a mask?
One thing that I hope we've all (most of us, anyway) have realized is that small particles get in the air. While we absolutely cannot avoid all particles, regardless of what level of mask we wear, we can reduce the quantity - or load - that we inhale.
So, I grabbed my gaiter and went to work. I also put it on while painting because, my logic told me that, while rolling paint on, there would be droplets invisible to the eye that would get in the air that I certainly didn't want to breathe.
Am I certain that I'm right? No, as I have no way to test my hypothesis in a practical way. Err on the side of caution? We all measure risk. Protecting my lungs from harm is something that makes sense to me!
