Short answer

For a tear or gouge, lay a spare piece over the damage with the pattern aligned, cut through both layers at once, remove the damaged piece and drop the patch in. For a bubble, slit it along a pattern line and inject adhesive with a syringe.

Sheet vinyl is patched by cutting the patch and the hole at the same time, so they are identical by definition. It is the one technique that turns a visible repair into an almost invisible one.

What you'll need

A spare piece of the same vinyl
A sharp trimming knife with new blades
A straight edge
Masking tape
Vinyl flooring adhesive and a syringe
A seam roller
Seam sealer, if available

Step by step

Decide whether to patch at all.A patch in the middle of a plain floor always shows a little. In a busy pattern, or under a table or an appliance, it disappears. Be honest about where the damage is.
Find matching material.An offcut, a piece from under an appliance, or a piece from inside a cupboard. Cutting a donor piece from a hidden area and patching that hole with anything is the classic move.
Align the pattern.Lay the donor piece over the damage and shuffle it until the pattern lines up exactly. Tape it down firmly on all four sides so nothing can shift.
Cut through both layers at once.A sharp knife against a straight edge, following a pattern line wherever possible. One firm pass rather than several — repeated passes wander.
Follow the pattern, not a rectangle.Cutting along a grout line, a plank edge or a strong pattern feature hides the joint completely. A rectangle in the middle of a pattern is obvious.
Remove the damaged piece.Warm it with a hairdryer and lift it out with a scraper, then scrape the old adhesive off the substrate.
Dry fit the patch.It should drop in with no gap and no overlap. Adjust before any adhesive goes down.
Bed it in adhesive.Spread thinly, let it become tacky, drop the patch in and roll it from the centre outwards.
Seal the seam.A vinyl seam sealer run along the joint chemically welds the edges and stops water and dirt getting in. It is what makes the repair last.
For a bubble, find out why.A bubble is a failed bond. If the floor is damp or the adhesive was never right, injecting more adhesive is temporary.
Slit and inject.A single knife cut along the length of the bubble, ideally on a pattern line, then adhesive injected with a syringe through the slit.
Roll and weight the bubble flat.Work the air out towards the slit, roll it, and weight it overnight. Seal the slit afterwards.

Tips

Change the blade before you make the cut. A blade that has cut anything else is already blunt enough to tear vinyl rather than slice it.
Warm the vinyl gently with a hairdryer before cutting. It cuts more cleanly and the patch beds down flatter.
Take a donor piece from inside a fitted cupboard, under the fridge or behind a door. Nobody sees those and the patch there does not need to be invisible.

Common mistakes

Cutting the patch first and then the hole — Two separate cuts are never identical, so there is always a gap or an overlap somewhere. Cutting both together guarantees a perfect fit — it is the whole point of the technique.
Not sealing the seam — An unsealed cut edge in vinyl lets water and dirt down to the substrate. The edges then lift and discolour, and within a year the patch is visible for a reason that had nothing to do with the pattern match.

If it doesn't work

Patch visible as a line

Cause: Cut across the pattern rather than along it — Fix: Redo following a pattern feature; seal the seam.

Patch edges lifting

Cause: Seam not sealed or adhesive short of the edge — Fix: Lift the edge, apply adhesive right to the cut and seal the joint.

Bubble returns after injecting

Cause: Damp substrate or contaminated surface — Fix: Test for moisture; the section may need lifting and relaying.

Patch sits proud

Cause: Old adhesive left under the patch — Fix: Lift, scrape the substrate flat, and re-bed.

Questions people ask

Can cushioned vinyl be patched?

Yes, and it patches well because the pattern is usually busy and the surface forgiving. The seam sealer matters even more, because water into a cushioned backing spreads.

How do I get rid of a small dent rather than a tear?

Gentle heat from a hairdryer sometimes relaxes a dent in vinyl and it recovers. Deep indentation from a heavy appliance foot is usually permanent.
