Published: July 2026 | By IdeasWood | 8 min read

Protect your log cabin investment with professional wood impregnation. Koralan UK 110 is the essential first layer of protection against pests, fungi, moisture, and weather damage. This comprehensive guide covers treatment options, client responsibilities, and long-term maintenance requirements.

Why Wood Impregnation Matters

Wooden log cabins face constant environmental challenges. Moisture infiltration, fungal growth, insect damage, and UV degradation can compromise structural integrity within months if left unprotected. Professional wood impregnation treatment provides crucial initial protection while you apply final color treatment to ensure decades of durability.

Frequently Asked Questions

Is impregnation treatment mandatory?

Highly recommended. Untreated wood requires painting within 7 days of assembly. Impregnation provides a grace period and extended protection during your preparation phase, but must be followed by color treatment within 12 months.

How long does protection last?

Impregnation typically provides 3-5 years of protection, depending on climate and maintenance. This is why color treatment within 12 months is critical – it extends protection to 5-10+ years.

Can I apply color treatment myself?

Yes. Professional-grade exterior paint or stain applied in 2 coats is recommended. Quality matters – poor application can compromise protection. Follow paint manufacturer’s specifications for your climate zone.

Is it safe for families with children?

Yes. Fully cured Koralan UK 110 is non-toxic and safe for residential use, including sauna and hot tub applications.

What if I don’t treat the wood?

Wood will begin deteriorating within 6-12 months. Mold and fungi growth becomes likely in damp climates. Your manufacturer’s warranty becomes void if color treatment isn’t applied within 12 months.

Can I paint over impregnation later?

Yes, preferably after 6 months for optimal adhesion. Impregnation provides an excellent base for paint and extends the painted finish’s service life compared to untreated wood.
