I recently came across some info for Woodguard TC (top coat), but cannot find the product anywhere.  Is anyone familiar with this, is it still available?

I am applying Woodguard to my home and curious if there are any compatible, breathable top coats for a this penetrating stain?  If so, what is the best means for reapplication of the stain once top coat is applied?

I don't know where to find Woodguard TC, but I can tell you that traditional top coats, almost all of which are water-based, will NOT work over top of Woodguard. Woodguard contains non-drying oils - waxes and what not - that interfere with the adhesion of these top coats. You'll experience similar incompatibility issues with most caulking and chinking products over Woodguard, as well. 

Probably not the answer you necessarily wanted or needed, but figured it might help with your research.

Thanks Charis. I sampled transformation and like that as well, although obviously a different type of oil. Most of the wood is pretty dried out and clearly hasn't been treated in years (we bought home 1 year ago). Will transformation adhere over previous finish even if not completely removed. The wood gets very clean with as little as a nylon bristle scrub brush and low pressure wash, although I've used a wash as well, but some finish remains on the more protected areas such as under eaves and north elevations. Prior stain is dark brown with hint of red, so I'm leaning that direction to avoid disparities in color with new stain.

Transformation will usually adhere over previous stains, as long as they've weathered for a minimum of 18 mos. Sounds like you're well beyond that. THAT SAID, it's quite possible the wood itself isn't "sound," meaning free of any loose wood fibers. The low pressure and scrub brush may do a good job of removing any dirt and discoloration, but it may not be vigorous enough to remove those wood fibers. If those wood fibers aren't removed, they'll eventually fall off the logs, carrying with them any stain applied over top. In order to remove that wood fuzz, it will take either a vigorous power wash, along with sanding afterwards to remove wood fuzz.

If you want to, take a minute to visit to download our booklet called "Restoring The Dream." It gives you some basic knowledge on log home refinishing and restoration, what the wood needs to look like before applying more stain, and will give you a fuller idea of what kind of work you may need to do. Your low pressure wash may be enough, or you may need something more extensive.

Hope that helps some. Good luck with your project!

What about Sherwin Williams Woodscapes Solid Color Stain?

Do you mean is there a clear top coat for Woodscapes Solid? Most water-based clear coats will go over a solid stain without any issues. That said, the difference in elasticity between the two products could cause some issues. If one or the other creates a less flexible coat, it will likely crack/peel in a few places when the other, more elastic one pulls at it. It's not usually wide-spread cracking and peeling, but still leaves those spots susceptible to moisture infiltration, so you have to keep your eye on things w/ regular maintenance checks and do the repairs where needed, when needed.

Hope that helps.

Adam, I would stay as far away from Transformation stain as you can. We had it put on our new log home by one of their so-called Certified contractors and it was still the absolute WORST product I have ever encountered. Within two years it was curling along exterior window sills, it was turning black (despite being cleaned before staining with Log Wash), etc, etc, etc. We had our home thoroughly scrubbed and cleaned and restained with Transformation at years 2 and 4 and the Transformation stain never performed as it was claimed it would. Finally, we had the crap blasted off of our home and had it re-stained with Woodguard and it looks great.

Transformation really is far from being a "stain" as it is a film-forming product (ie. a tinted "coating"). It b y no means penetrates the wood and protects it as Woodguard does. In fact, we observed that when Transformation stain gets wet from rain etc, it turns "milky" colored and this is especially noticeable at the bottom of logs where it may be somewhat thicker. My inclination is that it absorbs the moisture - which is never a good thing for a log preservative/stain.

We have also noticed many, many, many log homes with the same issue (black/darkening of the "coating")and they too have Transformation stain on them.

I would talk to several of the large log home refinishers that service your area and ask them (1) what they use, and (2) what their experience with Transformation stain has been. I can tell you that it is difficult to remove as well, and that it may work well in Colorado's climate, but it is worthless in the PA, NY, OH and WV area. I would not recommend it to my worst enemy!
