Me too.
Teenagers not kids, im still a kid.
$12 garage floor seal today..... its not real permanent, but will keep the dust down for the next few months.
Should be enough time for a paintjob.
My floor makes a lot of dust, as i made the mix of cement a bit wrong on a couple of sections.
So a $12 bottle of pva glue, mixed with equal parts water, (8l gave 2 coats) and a $1 rolling sleeve.
First i swept, blasted it with a leaf blower about 5 times and finally a wash with a pressure washer to get the rest of the dust off, and make the concrete damp.
Pva glue is the same as Bondcrete, so i figured it should go well on concrete. A small test 6 months ago confirms it.
