Swedish finish (acid-curing conversion varnish like Glitsa) has been used in Oregon and the Pacific Northwest for decades. It gives floors a hard, high-gloss shine, but off-gasses formaldehyde and strong solvents that force families to move out of the house for 7 to 14 days. Modern 2-component waterborne finishes like Bona Traffic HD match that durability without the toxic fumes, fire hazards, or mandatory hotel stays. Below is an honest breakdown of how the two finish types compare on durability, fumes, drying times, and real costs for Portland homes.
Service area fit
We help homeowners throughout Portland, Lake Oswego, Beaverton, West Linn, Tigard, Tualatin, Hillsboro, Happy Valley, Gresham, Oregon City, and Vancouver WA choose the right finish for their lifestyle. For years, Pacific Northwest contractors stuck with Swedish finish simply because it was cheap to buy and dried hard. Today, as people restore 1920s Douglas fir in Sellwood and Irvington or white oak ranches in Beaverton, most families want durable finishes that don't force them out of their homes.
Pricing factors
Looking only at a contractor's square-foot quote can be misleading. Swedish finish chemicals cost less for a contractor to buy off the shelf, but you also have to pay for a week or two of hotel rooms, dog boarding, and furnace filter changes once the vapors dissipate.
Direct comparison: Swedish finish vs commercial waterborne
Project planning
The finish you choose changes how you plan your week:
- With Swedish finish: You need to pack bags, find a hotel or Airbnb for 7 to 14 days, board dogs and cats, seal open food in plastic bins, turn off gas pilot lights on water heaters and furnaces, and warn your neighbors about strong exterior exhaust fumes.
- With Bona Traffic HD: You can stay in your house, keep your heating or AC running normally, and walk into the room in socks just a few hours after the last coat dries.
Common floor issues
Choosing the right finish prevents several common headaches in our wet climate:
- Lingering Chemical Odor: Swedish finish fumes absorb into sheetrock, drapes, and HVAC ducts, lingering for weeks after contractors finish.
- Orange Ambering on Douglas Fir: Swedish finishes turn Douglas fir and white oak an intense orange-yellow as sunlight hits them. Bona Traffic HD remains clear and keeps the wood looking light and natural.
- Winter Season Movement: Willamette Valley homes swing from wet, humid winters to dry summer heat. Stiff Swedish finishes can crack along board seams when wood moves. Flexible 2-part waterborne polyurethanes expand and contract with the boards.
- Pet Claws: Modern ceramic-reinforced waterborne finishes flex when dogs run across them rather than chipping off in white scratches.
Materials and finish guidance
Modern waterborne finishes are nothing like the thin, milky finishes from the 1990s. Products like Bona Traffic HD and Loba 2K use cross-linking agents and microscopic ceramic particles that hold up to heavy restaurant and commercial foot traffic. Sealers like Bona NaturalSeal or NordicSeal also allow you to keep raw Scandinavian tones without the artificial pink or orange tint caused by solvent-based finishes.

Frequently asked questions
Q: Why do some contractors in Portland still use Swedish finish?
A: Swedish finish has been around for decades in the Pacific Northwest. Many contractors learned on it 30 years ago, and the chemicals are cheaper to buy than modern 2-part commercial waterborne finishes.
Q: Does Bona Traffic HD hold up as well as Swedish finish?
A: Yes. Taber abrasion tests show Bona Traffic HD matches Swedish finish in foot-traffic wear while handling board movement and impact better without chipping.
Q: Will waterborne finish turn my wood orange?
A: No. Waterborne finishes dry crystal clear and contain UV blockers that prevent the ambering common with oil and acid finishes.
Q: When can dogs walk on the floor?
A: With Bona Traffic HD, pets can walk on the floor in 24 to 48 hours. With Swedish finish, animals must be kept away for at least 7 to 10 days due to toxic solvent off-gassing.
Q: Do I have to turn off gas pilot lights with waterborne finishes?
A: No. Waterborne products are non-flammable and safe around gas water heaters and furnaces.
Floor care guidelines
- First 24 Hours: Walk in clean socks only. Keep humidity between 35% and 55%.
- First 72 Hours: Finish hits 90% cure. Move furniture back using clean felt pads under all legs.
- First 7 Days: Avoid area rugs so the floor cures evenly with ambient airflow.
- Routine Cleaning: Vacuum with a bare-floor tool and clean with a damp microfiber mop and wood floor cleaner. Never use steam mops.
