After lots of reasearch and questions I have begun refinishing my home. It is roughly 2500 square feet of log surface area, and is made from D profile tongue and groove yellow pine logs. It was previously stained with Woodguard and then painted over, and then neglected. Surprisingly the wood is in relatively good condition. I am going to apply Sashco Transformation and will be taking it down to bare wood before applying the stain.
I asked on an earlier post about smoothing out the deep grooving that exists on the surface of the logs, and after rremoving the paint and most of the Woodguard stain I think I have determined what this gooving is. It appears that sometime in the past the logs were blasted with way too much gusto, and as a result there are many surface areas that are very rough and have had small grooves blasted onto the surface of the logs.
I want to take these rough areas down to smooth wood but do not know the best tool to use. Right now I am thinking that an angle grinder would be best, but am unsure of what kind of sanding disks to use, how many I will need, and were to get them. I saw zirconium sanding disks at Lowes that appeared like they would work, but I am unsure if these disks are safe to use on logs.
There are a few locations that are extremely rough and will be difficult to smooth by sanding alone. I was considering using a Wood Shark Grinding Disk for these areas before sanding.
Any suggestions are appreciated.
Yeah, definitely not clear pictures on that site. I believe it is the same thing as this product from Perma-Chink: http://www.pcsproducts.com/p-81-grinding-disks.aspx
I started sanding yesterday using the grinder and the hook and loop sanding disks you recommend. They are working well. In fact the area I was concerned the most about (the locations with the damaged surface) is very easy and fast to sand down to smooth, clean wood. The area I was least concerned about (under the porch where it has weathered the least) is much more difficult. All in all I am making good process with these tools, and hope to have it finished in 3 or 4 weekends. Thanks again for your advice.
