They will need to be ground clean and then sanded before applying a good latex interior stain made for log homes. Call Timeless Wood Care at 800-564-2987 for help and the materials you will need.

It is probably due to weather conditions, humidity & temp.

I would brush roofing tar on the part of the logs in the ground after applying a good borate treatment to the entire log.

A lot of it has to do with the weather conditions. This happens all of the time with log homes.

It should be done within 3 years. You will want to watch the finish and once you notice that the sheen is dissipating it will need an application.

Yes you could put siding over the logs, but you MUST get the rot repaired before you do or it will continue to rot under the siding and cause structural issues in time. Call Ryan at 877-788-5647 for help.

This is one for a flooring specialist. Someone in your area should be able to help answer this.

You could, but more than likely as the Sikkens continues to fail under the solid stain it will peel away. Nice part about solid stain is you can do spot repair work without a lot of hassle.

Call Dave at 800-564-2987. He should have a couple of products for you.

I guess it depends on the condition of the varnish, but eventually it will have to come off. Stay with a good quality latex log home stain like Life Line.
