How do I maintain a stained Ipe deck in Ottawa compared to pressure-treated wood?

Ipe decks require dramatically different maintenance than pressure-treated lumber, and Ottawa's extreme climate makes these differences even more critical. Ipe is a dense Brazilian hardwood that naturally resists moisture, insects, and decay, but it weathers to silver-gray without regular oil treatment, while pressure-treated wood needs more frequent staining and sealing to prevent rot and splitting.

For Ipe maintenance in Ottawa, the key is understanding that this wood doesn't absorb stain like softwood — it needs specially formulated hardwood oils or penetrating sealers. Products like Penofin Hardwood Formula or Messmer's UV Plus for Hardwoods ($60 to $80 per gallon) are designed to penetrate Ipe's dense grain structure. You'll typically need to clean the deck with a hardwood cleaner first, then apply the oil when temperatures are between 15 to 25 degrees Celsius with low humidity — ideal conditions occur in late May through early September in Ottawa. Ipe maintenance is typically needed every 12 to 18 months if you want to maintain the rich brown colour, compared to pressure-treated decks that often need attention annually.

Pressure-treated lumber maintenance in Ottawa involves more aggressive staining because the wood is more porous and vulnerable to freeze-thaw damage. Semi-transparent or solid stains ($45 to $70 per gallon) provide better protection than clear sealers, and you'll need to restain every 2 to 3 years depending on sun exposure. South and west-facing sections of pressure-treated decks take the most punishment from Ottawa's intense summer sun and need more frequent touch-ups.

The critical difference is timing and product selection. Ipe can handle Ottawa winters with minimal treatment, but pressure-treated wood that isn't properly sealed before freeze-up will show splitting, checking, and board warping by spring. Never use standard deck stains on Ipe — they'll sit on the surface and peel. Similarly, hardwood oils won't provide adequate protection for pressure-treated lumber.

Both deck types benefit from annual cleaning and inspection, but Ipe forgives neglect much better than pressure-treated wood. If you're dealing with an older Ipe deck that's gone completely gray, restoration involves sanding or using a hardwood brightener before oil application — a job that often warrants professional help given the specialized products and techniques required.
