if you've got some weathered wood siding that needs a repair you could put up fresh wood and wait for it to weather in and look natural but there's a better way I'd like to attribute this tip with it's anonymous I heard somebody talking about this in a lumber yard in the West Coast 20 years ago and the idea was to simply take some baking soda mix it with water and paint it on the kind of wood that you'd use outside something with a lot of tannins in it because that resists exterior conditions so what we're gonna do is we're simply gonna mix up some baking soda it doesn't take very much baking soda and if you're wondering an exact measurement I don't really don't have one it's a couple of tablespoons for probably you know a half a cup of water it's pretty milky white you know and you can see the particles floating around in here and you have to stir it regularly to keep it from settling out on the bottom but once you get it dissolved you simply start to paint it onto the the project now the piece of wood that I've got here is a piece of Redwood it works especially well on redwood it also works on red cedar I've tried it on that I've also tried it on oak I've even tried to undo gloss fir one time it worked on that not so good on pine all right looks a little wet now but fortunately I've done a test piece of this and it's been drying over in the corner so I can show you what it looks like after it's been sitting for a couple of hours this is a size had about three applications on it you can see where it's slightly discolored in here slightly darker that's where I took a rag to get rid of there's gonna be a little powder residue on here I took a rag to get rid of that and ran over a little bit and that's what just a little bit of baking soda will do here's the same thing same idea with a piece of white oak this has got three applications on it and this is one application this is no applications down here again it's a wood that's high in tannins and that's what's reacting with the baking soda if you're wondering what this does on the outside is that going to affect the wood pretty the natural aging of the weather is going to take over and and it will blend in it's it really works amazing I want to try this on furniture it works really good on oak thanks anonymous you
