Measuring, Taping and Cleaning a Tap Floor
Share
Three things go wrong when a studio orders its first marley floor: the quantity is worked out in square metres, the seams are taped with the wrong product, and six months later someone cleans it with whatever was under the sink. All three are avoidable in about five minutes of arithmetic and one correct shopping list.
The metreage sum
Adagio and Adagio Tour both come 1.6 m wide on a 31 m roll. You cover a room in parallel runs down its length, so the number that matters is how many 1.6 m strips fit across the room — not the floor area.
Runs = room width ÷ 1.6, always rounded up.
Linear metres to order = runs × room length, plus a little for squaring up.
A 9 m × 12 m studio: 9 ÷ 1.6 = 5.6, so six runs. Six runs down a 12 m room is 72 linear metres. Note that 72 linear metres is not the same as the room's 108 m² — and it is not 108 linear metres either. Ordering by area is the single most common way a first floor order comes out wrong.
Round up, then round up again. A partial run still costs a full 1.6 m width — there is no half-width. And a run that comes up 200 mm short against a wall cannot be fixed with an offcut without putting a visible seam in the middle of the room.
Our rule of thumb: add one metre per run for trim and squaring. On the example above, order 78 linear metres rather than 72.
At 31 linear metres a roll, 78 metres is two full rolls plus a cut length, or three rolls if you want the spare. We cut Adagio by the linear metre, so you are not forced up to the next whole roll.
Which tape goes where
There are two completely different jobs here and they take different products. Using one for the other is the second common mistake.
| Seam tape (on top) | Joins the runs where they butt together and keeps the join flat. Goes on the surface, in a colour matching the floor — or clear, which reads least under light. |
|---|---|
| Double-stick tape (underneath) | Holds the floor down. Goes under the perimeter and under every seam. Nothing visible from above. |
Butt the runs, never overlap them
Runs go edge to edge with no gap and no overlap. An overlap is a ridge, and a ridge under a tap plate is both a trip hazard and the place the floor will start to fail.
For tap specifically, use the double-stick
This is the one place we would push harder than a general dance floor guide. Tap drives the floor sideways far more than ballet or contemporary does — the whole technique is lateral force against a surface that has to stay put. Seam tape alone will let runs creep over a term, and once a run has crept the seam opens. Double-stick under the perimeter and the seams is cheap insurance in a tap room.
Rosco recognises three installation methods: temporary (taped seams), semi-permanent (double-stick) and permanent (full adhesive with welded seams).
Permanent is Adagio 2000 only — Adagio Tour is specified for temporary installation. Adhesive quantities, welding and subfloor preparation are all set out in Rosco's Dance Floor Installation Manual, which is the authority on method — not us.
Cleaning, and why the wrong product is a safety issue
Rosco makes two cleaners for these floors: an all-purpose one for routine cleaning and a heavy-duty one for built-up grime and residue. Use those.
Household detergent is the problem, not the dirt. Supermarket floor cleaners and dish detergents leave a film. On a dance floor that film changes how the surface releases underfoot — sometimes grippier, sometimes slicker, usually unevenly across the room. That is a safety matter rather than a cosmetic one, and it is the most common reason a floor that was fine last year suddenly feels wrong.
We are not going to invent a cleaning schedule for you: Rosco publishes no frequency guidance, and a floor doing twelve tap classes a week is not comparable to one doing two. The honest version is that routine cleaning goes on whatever cycle your room actually needs, and the heavy-duty cleaner comes out when routine cleaning stops bringing the surface back.
The shopping list
For a taped installation, per room:
- Rosco Black Marley Floor Tape — 50 mm × 33 m, $45 — or grey / white to match, or clear vinyl tape if you would rather the seam disappeared
- Rosco Double Stick Floor Tape — 48 mm × 25 m, $79 — one roll per perimeter plus seams; measure before you order
- Rosco All Purpose Floor Cleaner — 9116, 3.8 L, $165
- Rosco Heavy Duty Floor Cleaner — 9112, 3.8 L, $195
Send us the room instead. Email sales@cfats.com.au with the width, the length and what is underneath, and we will come back with the cut length, the roll count and the right quantity of tape. Floors and pricing are on the tap dance floor page, and the case for Adagio under tap shoes is in why tap sounds different on Adagio.
