Quick Answer
SMOOTHING THE INTERIOR WALLS OF AN IGLOO: To achieve a smooth interior, an igloo builder uses a combination of snow removal and re-packing techniques. This process involves scraping away the rough surface of the snow blocks and re-compressing them to create a smooth finish. The end result is a stable and comfortable shelter.
Removing the Rough Surface
To smooth the interior walls of an igloo, you’ll need to remove about 1-2 inches of the outer snow layer. Use a blunt instrument, such as a shovel or a snow scraper, to gently scrape away the surface. Be careful not to damage the underlying snow structure. Remove any debris or ice fragments that may have accumulated during the scraping process.
Re-packing the Snow
Once you’ve removed the rough surface, use a snow shovel or a special tool called an “igloo knife” to re-pack the snow. Hold the shovel at a 45-degree angle and gently push the snow back into the wall, using a compressing motion to pack the snow tightly. This process should be repeated several times, until the entire wall is smooth and even. Aim for a wall thickness of around 12-18 inches to ensure stability.
Final Touches
After re-packing the snow, use a long, thin tool, such as a wooden dowel or a snow rake, to smooth out any remaining imperfections. This will help create a uniform surface and prevent ice crystals from forming. Apply a thin layer of snow to the wall, using a circular motion to blend the new snow with the existing surface. This will help create a seamless finish and ensure a comfortable interior environment.
