Over time, your log home’s exterior can become dirty, grayed, and covered in mildew. Sandblasting provides a deep clean to restore the wood’s natural color and texture. But how do you know when it’s time for this intensive process? Consider log home exterior sand blasting when you notice these telling signs.

Significant Dark Streaking

If you see extensive dark or black streaks and spotting on the logs from mildew, mold or grime, sandblasting is probably warranted. These streaks indicate a deep dirt buildup that routine cleaning can’t remove. Sandblasting penetrates and lifts away the deepest staining for a refreshed look.

Buildup in Nooks and Crannies

Check crevices, joints between logs, undersides of overhangs and other nooks and crannies closely. If you notice heavy dirt or mildew accumulation in these tricky areas that evade normal cleaning, sandblasting can thoroughly clean what brushes simply can’t reach.

Previous Stain Won’t Adhere Properly

If it seems like new stain just won’t adhere properly or soaks in unevenly during re-finishing, excessive dirt is likely preventing proper penetration. Sandblasting will completely strip away all residue so the wood absorbs stain evenly again.

Flaking or Bubbling Paint

If existing paint or stain has started severely cracking, flaking or bubbling, it means the wood needs to be taken down to bare fibers again for proper adhesion. Sandblasting completely strips the damaged layer, so fresh stain can adhere and protect the logs.

Visible Wood Damage From Moisture

Carefully inspect for graying, splintering or swelling wood, which indicates moisture damage. Sandblasting can restore moderately damaged wood by removing the degraded surface layer to uncover better wood underneath.

Logs Look Grimy Despite Scrubbing

If your cabin’s logs just look grimy, dingy and dirty no matter how much you scrub them, sandblasting is a sure way to renew the wood’s natural color and pattern. It provides a deep clean when surface washing fails to cut it.

Prepping for Major Remodel or Addition

Anytime you plan a major wall redo, addition or remodel, consider sandblasting first. It takes the exterior down to an even, fresh-wood look before restaining. This ensures your new stain or treatment adheres evenly across the whole surface.

As Part of Regular Upkeep

Some homeowners opt to sandblast their log exterior every 5 to 10 years as part of regular upkeep between deep cleanings. How often depends on your climate and preference, but it’s an effective way to rejuvenate siding periodically.

Recognizing when to call in professional sandblasting services helps keep your log exterior in optimal shape. If discoloration, staining and buildup persist despite regular care, it’s time to sandblast. Proper prep is key for the best stain absorption and adhesion in future treatments.
