- 39How to tile over an uneven subfloor without tearing it upAn uneven subfloor makes tiles crack and shift if they are laid without a flat surface. Fixing low spots with a feather finish patch or self-leveling compound avoids tearing out the old plywood or linoleum entirely.
- 31How to remove old dried adhesive before laying LVP flooringOld dried adhesive must be scraped away completely before laying a vapor barrier and LVP. Scraping old residue by hand is extremely tedious and can take hours per strip, which stops installers from easily prepping the subfloor.
- 5Painted concrete basement floor keeps dusting and crumblingConcrete floors dust and crumble when the surface is inadequately prepared before painting or damaged during renovations. This breakdown lets dust push through the failing paint and prevents you from maintaining a clean, sealed surface.
- 5How to fix a botched self leveling compound job with dipsWhen self-leveling compound sets too quickly, it leaves behind unexpected high spots, thin coverage, and persistent dips in the subfloor. Fixing this botched application requires grinding down the high areas and pouring a fresh, properly mixed patch layer before you can safely install new flooring.
- 3Removing thousands of embedded staples from a subfloorFloor scrapers often glide right over old flooring staples because they are deeply embedded in the wood. Extracting them individually with pliers takes forever, but simply hammering them flat will cause the new floor to crackle and pop.
- 2How long to wait after floor patch before installing LVT?The exact waiting time between applying a patching compound like Feather Finish and setting luxury vinyl tile is unclear. This uncertainty leaves people questioning if they can safely install their new floor the very next day, especially if the surface required multiple coats.
