With the first coat, apply the coat generously with a square of the cotton t-shirt rag, and allow it to soak for 15 minutes. Tack cloths are treated with materials that can interfere with the polyurethane. Hit it with 400 grit sandpaper one more time, and wipe it down with a dry microfiber cloth. This raises the grain and gives you an opportunity to sand once more and have a much longer-lasting finish. Wipe it down with a moist microfiber cloth. If sanding for a smooth finish, I like to use 300 or 400 grit sandpaper. If you are using an “off-the-tool finish”, you can skip steps 5-7 and move onto step 8 where you will be ready to wipe on the finish. In the Mason jar, mix equal parts boiled linseed oil, oil-based polyurethane, and mineral spirits (the amounts don’t matter, as long as it’s all equal parts, I try to only make as much as my project needs so I’m not having to store jars of unused furniture finish). Gloves - As a safety precaution, I recommend using gloves and working in a well-ventilated area.ĭon your gloves, and set up your project in a well-ventilated area. They will leave bubbles on the surface of your finish. Rag - Old cotton t-shirts work really well to avoid streaking that a natural bristle brush can leave behind. I generally just use a piece of scrap wood from my woodshop. Stirring Stick - This does not have to be anything fancy. Mason Jar - I like to mix and store the furniture finish in a mason jar because they have an airtight seal and handy dandy measuring marks on the side. I commonly use Jasco Odorless Mineral Spirits. Mineral Spirits - The mineral spirits help both of the other components dry faster. With water-based finishes, this recipe will fail.*** I don’t know about you, but I hate sanding! *** A common mistake people make is not making a distinction between water-based polyurethane and oil-based polyurethane. ![]() This clear satin spar varnish still adds a warm amber hue, and I love it because I don't want the finish to be super shiny which requires quite a bit of sanding to cover flaws left behind. ![]() I commonly use Helmsman Indoor/Outdoor Spar Urethane. Polyurethane *** - The urethane helps the boiled linseed oil to harden and therefore protects against water damage and other elements. It does not, however, harden well, which is the job of the polyurethane. Boiled Linseed Oil - I commonly use Jasco Boiled Linseed Oil which oils and protects the furniture and gives it a beautiful glow.
