Rosthern Log Home Restoration: A Failing Stain That Was Starting Rot

A failing stain stops being a cosmetic problem the moment it stops keeping water out. That’s where this log cabin in Rosthern, Saskatchewan had landed — the old finish had given up, and rot was already working into the logs underneath it. Frontier got the call to do the one thing that actually fixes that: take the finish all the way off, back to bare wood, and rebuild the protection from there. Here’s how that played out, log by log.

The Project: A Log Cabin in Rosthern, Saskatchewan

Rosthern sits in central Saskatchewan, between Saskatoon and Prince Albert. Frontier’s crew is fully mobile, and log homes across the prairies are familiar ground — we’ve stripped and refinished a Pioneer log home in St. Wahlburg and a lakeside cabin on Lake Katepwa, and we work right across Saskatchewan.

The Problem: A Failing Stain, and Rot Starting Underneath

This cabin’s old stain was failing, and that failure was already creating rot issues underneath it. This is the part homeowners tend to miss. A finish is the wood’s raincoat — once it breaks down, water gets into the logs and stays there, and wet wood is where rot starts. Brushing a fresh coat over a finish that has already failed doesn’t stop any of it. It just puts a new layer over the problem.

The only durable fix is to remove every coat and get back to sound, bare wood. That was the plan here.

Media Blasting Back to Bare Wood

To strip the old finish, the crew used media blasting rather than chemical strippers or sanding the whole cabin down.

Frontier blasts with 50/100 grit crushed glass — recycled wine bottles, 100% silica-free. It cuts through failed finish without the toxic runoff of chemical stripping, and the spent media is inert; it settles into the soil and in most cases acts as natural drainage for the lawn. Windows, doors and the foundation were masked off first, and every log came back to clean, raw wood ready to take a fresh finish.

Four Coats of Sansin Espresso, Sprayed and Back Brushed

With the logs bare, the crew put four coats of Sansin in Espresso back on — sprayed, then back brushed. Spraying lays the finish down quickly and evenly. Back brushing works it into the wood instead of leaving it sitting on the surface, and it catches the runs and thin spots a sprayer alone leaves behind. Four coats, applied that way, is what proper protection looks like on a log home.

It’s also why the finish choice matters here. Frontier has written before about why Sansin systems outperform oil-based stains — the short version is that a breathable finish lets moisture escape instead of trapping it under a film, and trapped moisture is exactly what leads to blistering, peeling and rot. On a cabin where a failed finish had already started causing rot, that’s the whole point.

Why We Take It All the Way Back

The logic is the same on every log home restoration we take on: strip the failed finish off completely, get down to sound bare wood, and rebuild with a finish applied properly and in enough coats to actually protect it. It’s more work than re-coating over what’s already there. It’s also the only version that holds — and on a home where a failing stain has already started causing rot, it’s the only version worth doing.

Seeing a Failing Stain on Your Own Logs?

If your stain is breaking down, the wood underneath is already on the clock — the longer it sits, the closer it gets to what you see in the photos above. This Rosthern cabin is what that looks like caught and turned around: blasting, prep and staining, all handled in-house by our own crew, the way it’s been done since 2000.
