The Log Home Neighborhood

An online log home community for log home enthusiasts.

I'm working with a log home company to restain our home, which was built in 2002. The original finish was a sashco cascade and did marginaly ok for durability. I contracted with the same log home company to re-stain it this year and use sascho transformation. They power washed it and then applied multiple coats of transformation... long story short it made it look lousy. Sashco recommends corn cobing the old stuff off before apply transformation, cuz the old stuff will bleed through.

The company came back and agreed to blast the house. The areas that were not coated with transformation were coming off very well, but the coated areas they had to really work it hard and the logs look very weathered now. The other areas with just cascade look great.

Are there other options to remove the newly stained areas without cratering the logs so much? My wife and I are concerned that this process is tearing off multiple years of wear-n-tear!!

Eek! I'm Charis with Sashco. I'm sorry to hear you're having such issues with removing our stain. Long story short: corn cob blasting and power washing won't do a whole lot to remove fresh stain, and unless done carefully, power washing will just gum everything up. The one thing that will do a pretty good job of removing fresh stain and/or power washing damage is blasting with crushed glass or chemical stripping. Blasting with crushed glass is much like cutting with surgical knives. The sharp, cutting edges of the glass are very precise and cut off the fresh stain, leaving the underlying wood in very good shape - no "cratering" that can occur with other types of blasting. Chemical stripping can be done but is much more labor intensive and environmentally unfriendly.

Give me a call at 1-800-767-5656 ext 164. We obviously want to help you get this done right.

Thanks for your reply. The freshly stained areas are all gummy and fortunately, the companies abrasive blaster equipment broke down. They aren't due to come back until Monday but had planned on blasting with Corn. I've provided them with your feedback and both of us will reach out to you to discuss. THANKS again.

Doug - FYI - I will be out of the office tomorrow. If you call the 800 # first thing in the morning, I'll have them connect you to my cell phone so we can discuss. Otherwise, you can reach me on Monday.

Thanks again! -- Charis
Apply a chemical stripper (maybe multiple times) to those area's and allow to work. remove it and have it blasted. Using finer cob material takes longer but looks better All the areas that are really pitted need to be sanded to knock the hard grains down and smooth out and harden the soft grain pitted areas. I have a few pics of some blasting pics take a look if you'd like. Hope this helps and there are plenty of enviromentally friendly strippers out there that do work.

Unfortunately most contractors and companies recommend media-blasting as the best way to remove old finishes. The truth is it is a terrible way to remove finish as you have witnessed. My company has been restoring log homes for over 20 years and the only way that we remove years of built up finish are by hand-sanding the building. This produces the best results and is less dusty and dirty than media-blasting and is environmentally friendly as opposed to chemical strippers. Please visit our website for some information on my company and the procedures we use to restore log homes. If you have any questions feel free to email me at or call me at (906)202-0595.

Hi Lee,

Hopefully you are still alive and well in the log business.  I realize this post is older then dirt but I'm looking for answers.  Sanding is pretty labor intensive right?  What do you use, Osbourne?  If so are there any grinders that don't vibrate your hands to sleep?  Any tips are appreciated! 

Please call me at 906-202-0595 or email me at

I am very well alive and have been growing my business. I will help you out with the overall process. I have some white sheets I can provide you with but I need an email address.

Best Regards,

Hi Doug, Sorry to hear of your problems. Fresh stain is hard to get off and in our way of thinking
any one who knows anything about it would never had tried to power wash or cornblast first.
We do a process where we use soygel We put it on any type of fresh stains or any type of
oil base stains and it is not a stripper but a dissolver and it pulls the stain out of the wood grains
and then we let it set for overnite and the next day we cornblast it off. It takes no life out of
your logs and looks great for you to borate and stain again. If you would like a information on
it just gives us a call at 866-906-2955. Yes cobblasting is dusty but done the right way is very effective and will not pit or harm the logs. Trouble is there are many out there that don't know what they are doing. Please visit our site at for more info.Good luck, Dolly
I agree I have not witnessed one log home whose logs aren't torn up from corn cob blasting even if you know what you're doing.
I've been to plenty of jobsites and witnessed contractors that were successful at corn cob, walnut, or glass blasting without damaging logs. I've seen many other methods work just as well.

While media blasting should be a last resort for homeowners and people who are not confident or haven't had success with the equipment, there are plenty of contractors that can media blast, do a light buffing where needed and leave your logs looking great.

The trick is to do your homework when hiring a contractor. Make sure that they have media blasted more than twice. Make sure they are insured, licensed and bonded. Check references and make sure they have a portfolio and are willing to give you the phone numbers of some of their past customers.

I guess my point is that yes you will be able to come up with pictures of blasted logs that look terrible. You will also be able to come up with pictures of the opposite if you are willing to research the subject further.

Media blasting is a tool, and in the right hands it can be an effective one. Good luck with your projects.

We have been blasting new softwood timber to make it look old (we call it WeatherAged) for years. It is much easier to control the depth and quality of the finish on a flat timber surface on the ground before installation. Not so much on a round log surface 12 feet high in the air. I imagine the applicators inconsistency and inexperience is adding to the woes expressed here. The spray angle (perpendicular to surface) and distance away from surface (6" or so) makes a big difference.

We've blasted hewn and planed surfaces with sand, walnuts, corn, baking soda (fire repair), glass, etc. At one time corn was a favorite when cheap. Walnut is too big. Sand has to be sized just right (like the three little bears). If you blast inside a home, it is a mess and using a reversed blower door works best.

Strippers are no fun with hewn surfaces. Too many nooks and crannies to reach. The best solution is to do it right the first time and spend the money on surface prep. Go to this picasa site to see some nice finished photography and try to find the stuff we've WeatherAged.

The website you posted is great - great pictures. It seems everytime I advocate on this forum for corn blasting, I get "blasted." I have been doing similar work for years - interior and exterior logs, doors, beams, etc. I really like the term "weatheraged." Is this a product or a term you have coined. Is it open for others (like myself) to use?

I have been trying to educate others that it is not the blasting, rather it is the blaster who determines the finished product. One thing I have not seen mentioned is the use of a fan nozzle when blasting. They certainly are not a cheap accessory to the corn blaster, but worth every dollar.

It appears you have been doing this for a long time, so I have a professional question:
I have been blasting log homes since 1982. I have used sand, corn, walnut and glass. 20/40 corn is my personal choice. There have been only two times that I found a finish I could not remove with corn. The most recent time, we tried soy-based and citrus-based strippers as well as corn and glass blasting and finally had to resort to sanders and mini grinders to remove the finish. The common factor in both these homes was that someone had previously sand blasted the logs (5 to 10 years before). The finish was a simple oil-based meseners UV plus - a product I have never had any trouble removing before. I did notice as we were sanding/grinding, there were fine particles of sand embedded in the logs.

So, do you think the sand blasting could have changed the composition of the finish of the wood that would make in near to impossible to remove the finish?

I am always interested in increasing my knowledge base and expanding the services I can offer my customers.

Thank you in advance for taking the time to give me your input.
