Hi all,
I've been asked to finish the wooden frames of a rather large contemporary house. The frames are pressure treated pine and the owner wants to use the Osmo product line.
I did some test runs on a few pine trim pieces with the Osmo colored woodwax. But I'm seeing a lot of blotching, as expected with pine. The blotching is very intense in some areas and I'd like to avoid it. So I'm reaching out to get some advice. I should add that I'm a newbie to finishing. So any help is much appreciated. Here are a couple of questions:
1- I haven't tested on pressure treated pine. The test piece that I used wasn't pressure treated. Is there any relationship between pressure treating and blotching. Will it intensify it or reduce it?
2. I know that I can use a sealer like shellac prior to the application of the Osmo to prevent blotching. But right now, even without the sealer the stain is not penetrating much and I'm afraid that the shellac might intensify this issue. Any suggestions?
3- The owner wants the Osmo because of its low VOC and its natural-looking matte finsih. From my point of view, the extra good thing is that you just do two quotes and you don't need to sand in between. Are there any other products with a similar profile (matte, low VOC, easy to apply)? I know Rubio has one. But that seems too expensive to me.
By the way, I just joined the forum and am looking forward to being a member of this amazing community!
Thanks again!
