1. Remove mill glaze, road grime and other foreign substances from the logs. You can do this by using a log wash solution (Wood ReNew), sanding, power washing or corn-blasting, depending on the condition of your logs.
2. If you elect to wash your logs with a cleaning solution, always remember to apply cleaners from the bottom of the walls upward, then rinse from the top down. Always make sure to thoroughly rinse cleaning solution off the walls. Follow manufacturer’s directions when using cleaners.
3. After waiting for the logs to dry, apply a borate preservative (Shell-Guard or Armor Guard) and allow to dry. Next apply your interior and exterior stains. You may want to apply your exterior clear-coats after chinking, to improve appearance and make cleaning easier. The final step is to apply external sealants and chinking if your house requires it.
4. All log homes will need some amount of sealing – regardless of the log profile or construction style – in between log courses, at corners and around windows and doors. the sealant or chinking you use must be compatible with whatever stain you apply to your log home. If you are not sure, call the manufacturer.
5. To test your finish or stain, use a spray bottle to mist the logs with water. If the water beads up and runs off like a freshly waxed car, then it’s doing it’s job. If logs soak up water, then you’ll need another application of finish.
6. How soon you will need to re-apply stains to your log home depends on many variables. Severity of weather exposure, care during preparation and stain application, the quality of the stain used and amount of pigments in the stain are the primary factors. You should expect 4-7 years or more when using LIFELINE stains, especially if the house is sheltered from the sun.
7. Graying wood (especially on the topside of round logs) is caused by UV damage to the wood substrate. To fix this, you must remove the stain to get at the wood underneath, by stripping or sanding. Treatment with Wood ReNew, OxCon or sanding removes this damage. This UV damage can be significantly delayed and reduced by use of UV-Boost in the first coat of LIFELINE finish on the logs.
8. If your finish loses its adhesion, it can start to peel, blister or crack. To avoid this peeling, only use one coat of stain to finish on logs that have more than 20 percent moisture content. Use a moisture meter to determine this. Once your log falls below 19 percent moisture content, you should apply multiple coats as per manufacturer recommendations.
9. Can you feel drafts at corners? Use Energy Seal or Perma-Chink to seal horizontal and corner joinery wherever needed. Seal upward facing checks larger than 1/8″ wide with Check Mate. These can trap and hold water and should be weather-tight.
10. Check flashing around the windows to ensure that all water is being channeled out and down the exterior walls. Water stains on the logs or drafts around the windows or doors indicate that air and water is infiltrating your home. The right sealant is the solution for this problem.
11. If blisters appear in chinking that has been applied in direct sun, puncture them with a knife tip and flatten them out against the uncured chinking.
