Best way to clean floor before placing carpet tiles
We are almost at the end of a basement renovation. We're just finishing up the painting, and then we'll put down carpet tiles. Before we put down the tiles, I want to clean up the concrete floor. The dry wall dust is everywhere! Really, we should have done this before painting. We've tried sweeping and then using the Shop Vac to suck up the piles. But still, dust remains. I tried a dry Swiffer, a wet Swiffer. The dust overpowers them. I can do a few square feet and then need to change out the cloths.
I am concerned that the tiles won't grip the floor correctly if it is not clean.
Any ideas about how best to get rid of all of this fine dust?
