How do I remove old glued-down vinyl tile from a basement concrete floor in a Moncton home before installing new LVP without damaging the slab?

Removing glued-down vinyl tile from concrete requires patience and the right approach to avoid damaging your slab. The adhesive used in older installations (especially pre-1980s) can be extremely stubborn, but with proper technique you can get a clean surface ready for your new LVP.

Start by testing a small corner section to determine what type of adhesive you're dealing with. Use a putty knife or floor scraper to lift an edge of one tile. If it comes up relatively easily with some adhesive residue, you're dealing with newer water-based adhesive. If it's rock-hard and the tile breaks into pieces, you likely have older solvent-based or cutback adhesive, which is much more challenging.

For easier removal, apply heat to soften the adhesive. A hair dryer or heat gun on low setting can warm the tiles enough to make scraping easier. Work in small sections, heating the tile for 30-60 seconds, then immediately scraping with a wide putty knife or floor scraper. Keep the tool at a low angle to avoid gouging the concrete. In Moncton's humid climate, this process works best during drier periods when the basement isn't fighting condensation on cool surfaces.

For stubborn adhesive residue after tile removal, you'll need a solvent approach. Citrus-based adhesive removers are safer for indoor use than harsh chemical strippers. Apply the remover, let it sit for the recommended time, then scrape with plastic scrapers to avoid scratching the concrete. Mineral spirits can also work but require excellent ventilation. Never use a grinder or aggressive mechanical removal on a basement slab - you risk creating low spots that will telegraph through your new flooring.

The concrete surface must be completely clean and level before installing LVP. Any remaining adhesive bumps or residue will create an uneven surface that shows through luxury vinyl planks. After all adhesive is removed, vacuum thoroughly and wipe down with a degreasing cleaner. Check for any gouges or low spots that might need concrete patching compound.

Before installing your new LVP, address moisture management - critical in any Moncton basement. Even if the old vinyl wasn't showing moisture problems, concrete slabs constantly wick moisture in New Brunswick's climate. Install a Dricore subfloor system or similar moisture barrier before your LVP. This prevents moisture wicking from below and adds a thermal barrier against the cold concrete.

This is definitely DIY-friendly work, though it's time-consuming and physically demanding. Plan for a weekend project and ensure good ventilation throughout the process. If you discover the adhesive contains asbestos (common in tiles installed before 1980), stop work immediately and hire a certified abatement contractor - this isn't worth the health risk.
