Supi Saunavaha Sauna Wax | Clear or Black, by Tikkurila

Sauna benches and walls take water, sweat and heat every session, and bare wood shows it. Supi Saunavaha is Tikkurila’s sauna wax: a water-based finish with natural wax that soaks into the wood and forms a barrier against dirt and water, for benches, paneled walls and ceilings, doors and window frames. Choose clear to keep the wood’s own color, or black for a dark finish. The clear can covers about 97 to 126 sq ft, and the wood is ready for use 24 hours after waxing.

How to wax a sauna

  • Prepare: clean new wood of dust, mist it lightly with water, let it dry and sand off the raised fibers. Wash old or dirty wood with Supi Saunapesu cleaner first, rinse, let it dry, then sand and wipe off the dust.
  • Protect the floor: the wax soaks easily into tile grout, so cover it.
  • Test: try black on a hidden spot, such as under a bench; the final color depends on the wood.
  • Apply: stir well, then put on one coat along the grain with a foam brush or sponge, no more than the wood can absorb, because too much leaves the surface slippery. Do small surfaces in one go and large walls one or two boards at a time.
  • Dry: it is dust-dry in 30 to 60 minutes and ready for use after 24 hours. Add a second, light coat the next day if needed, and keep coats thin on the benches, where a thick layer can make them feel hotter.
  • Heat it up: preheat and ventilate the sauna well before the first session.

Work when the wood is dry, the air is at least 41°F and the humidity is below 80%. Brushes clean up with water.

Good to know

  • It is not for oiled wood, unless the oil has worn almost completely away.
  • Colored wax wears with use, most of all on the lower benches, and you can recoat at any time the same way.
  • Wait about a month after waxing before washing the wood with Saunapesu.
  • For thermally modified wood, Tikkurila’s data sheet calls for the wax tinted to shade TVT 318R, so test clear or black on a hidden spot first.
  • The wax contains preservatives that can cause an allergic reaction, so wear gloves. Store it where it will not freeze.

More ways to look after the wood are in our sauna wood care collection.

Why we carry accessories

Accessories Are Great. A Sauna You Actually Use Is Better.

We stock accessories like this one so our sauna and heater customers can get everything for the room in one place. If you already have a sauna you love, welcome. If you are still planning one, or the one you have never quite gets hot enough, take a look at what we really do.

Free shipping for life on accessories

On its own, this ships for $24.95. Put it on the same order as a sauna or heater and it ships free. After that, accessories and materials like this ship free on every order you place with us, for life. Use the same email and we’ll recognize you at checkout.

The Rabbit Hole Ends Here

Did you always have opinions about cedar? No. No you did not. Most people shopping for a sauna end up with a dozen tabs open, three brands that all say they are the best, and a forum thread that argues both ways. We have built, installed and fixed saunas like the ones we sell, and we use our own at home. Tell us about your space and we will tell you which sauna and heater fit it, and which ones don’t.

  • A heater sized to your roomWe match the heater to the room’s volume, walls and glass, so it heats the way it should.
  • The whole project, thought throughSpace, electrical, freight and install get talked through before you order, not discovered after.
  • Still here afterThe same people answer when a question comes up mid-build, and long after delivery.

The best sauna deal is the one you don’t have to buy twice.
