How do I remove old vinyl floor tiles and their adhesive?

Lifting old vinyl tiles is mostly patience and heat. The one part that genuinely matters is establishing what you are dealing with before the first tile comes up, because some old floors should not be disturbed at all.

Safety

What you'll need

• A hot air gun or a wallpaper steamer
• A long-handled floor scraper
• A wide stiff scraper
• Adhesive remover or a citrus-based solvent
• Bin bags and a dust mask
• A floor scrubber or a stiff brush

Step by step

1. Date the floor before touching it.9-inch (229mm) tiles, a black tarry adhesive, or anything in a house that has not been refloored since the 1980s, should be treated as potentially asbestos-containing until tested.
2. Get a sample tested if in doubt.A UKAS-accredited lab will test a small sample inexpensively. It is worth the wait, and the answer changes the entire method.
3. For modern tiles, start at a damaged edge.Any lifted corner or a cut edge at a doorway. Getting the first tile out gives the scraper somewhere to bite.
4. Use heat.A hot air gun on the tile for twenty or thirty seconds softens both the tile and the adhesive. A wallpaper steamer works too and is gentler.
5. Push, do not chip.A long-handled floor scraper pushed at a low angle under a warmed tile lifts it as a piece. Chipping at a cold tile shatters it and takes ten times as long.
6. Work in a sequence.Straight rows from one wall, warming the next tile while lifting the current one. It becomes a rhythm and the whole floor goes far faster than expected.
7. Deal with the adhesive separately.The residue left behind is a job in itself. Adhesive remover, applied and left to dwell for as long as the tin says, then scraped wet.
8. Keep it wet.Wet scraping keeps dust down whatever the material. Never sand or grind dry adhesive residue.
9. Change scraper blades often.A sharp blade does the work. Most of the effort people expend on this job is spent pushing a blunt blade.
10. Neutralise and rinse.Solvent removers leave a film that stops new adhesive gripping. Wash the floor with detergent and rinse thoroughly, then let it dry fully.
11. Assess the substrate.Once clear, check for damage, damp and flatness. This is the moment to do the levelling and the moisture test.
12. Dispose of it properly.Bagged and taken to a household waste centre. Tiles confirmed as asbestos-containing must go through a licensed route.

Tips

• Encapsulating is a legitimate alternative to removal. Where tiles are sound and firmly stuck, a levelling compound over the top avoids disturbing them entirely — and is the recommended approach for suspected asbestos tiles.
• A powered floor stripper can be hired for a large area and turns a two-day job into an afternoon.
• Do the whole floor before you start on the adhesive. Switching between the two tasks doubles the setup time.

Common mistakes

• Sanding or grinding old adhesive residue — Dry abrasion of any old floor adhesive creates a great deal of fine dust, and if there is asbestos in the bitumen that dust is the actual hazard. Chemical removal and wet scraping are the only appropriate methods.
• Laying a new floor over solvent residue — Adhesive removers leave an oily film. New flooring adhesive cannot key to it, so the new floor lifts at the edges within months and the whole job has to be done again.

Alternatives

• Encapsulate rather than remove: Prime over the sound tiles and cover with a levelling compound or a ply overlay. Faster, less mess, and the correct approach where asbestos is suspected.
• Overlay with plywood: 6mm ply screwed over the existing tiles gives a fresh base without disturbing anything. Adds height, which matters at doorways.
• Powered floor stripper: Hired machine with a reciprocating blade. Worth it beyond about 20 square metres and dramatically reduces the effort.
