We live in an older house with large floor vents (1in square gap grates), 3 kids and 2 kittens so everything seems to manage to get into the vents and then the air ducts. Is there a way to help reduce the amount of "junk" that falls through but won't block airflow?
I recently painted my fireplace and used a masonry primer. It was quite expensive, and i have over a half a gallon left. Can i use it on interior walls and ceilings like normal primer? Thanks Y'all Very Much!!😁
