Quick Answer
Chinking over log cabin joints provides a durable waterproof seal, prevents air and moisture infiltration, and helps maintain the structural integrity of the cabin.
Sealing the Gaps
Chinking is a flexible filler material used to seal gaps between logs in log cabin construction. It’s essential to apply chinking to all gaps, typically 1/4 inch or larger, to ensure a watertight seal. A standard chinking application involves applying a bead of chinking to the gap, then using a chinking tool or putty knife to smooth and shape the material. For most log cabins, a 3/8 inch wide chinking is recommended.
Types of Chinking
There are several types of chinking available, including elastomeric, polyurethane, and polyurethane-foam chinking. Elastomeric chinking is ideal for joints up to 1/2 inch wide, while polyurethane chinking is suitable for larger gaps. Polyurethane-foam chinking is a good option for areas with high wind loads or where a higher level of flexibility is required. When choosing a chinking product, consider the cabin’s climate, log size, and joint width.
Applying Chinking for Long-Term Results
To ensure long-term results, it’s essential to properly prepare the joints before applying chinking. This involves cleaning the joints with a wire brush to remove debris and old chinking material. Next, apply chinking to the joint, following the manufacturer’s instructions for application and curing times. For optimal performance, reapply chinking every 10-20 years, or as needed based on cabin condition and weather exposure.
