Put on the polishApply only one thin coat. Then, remove any dust nibs with 1,500-grit sandpaper or a piece of brown paper bag. Finally, using a soft cotton rag or polishing pad, buff the finish to a high shine using automotive paste wax, photo below, which has fine abrasives that polish the finish even further.
It takes oil-based polyurethane 24 hours and water-based polyurethane 6 hours to dry enough to be able to walk on it in socks and proceed to the next step of the application process (sanding or applying the next coat). Don't confuse dry time with curing time which can take up to 1 month depending on conditions.
4.Prime the Surface
- Apply oil-based paint primer. Using a primer will give your paint a better surface to stick to. The primer also keeps any stains on the wood from coming through the paint.
- Allow the primer to dry overnight for best results. Another coat may be necessary if any wood grain shows through the primer.
Do I have to apply a clear coat after staining? While staining creates a rich, deep color that highlights natural wood grain, it does not provide long-term protection. A polyurethane top coat protects the wood from scratches, stains and water damage.
All but two of the finishes tested fared well, but the Minwax Wipe-On Poly was particularly impressive, drying in three hours to a light satin sheen and offering excellent water resistance. It's a thin finish that requires more coats to build when brushing, but it still yields good results.
Gloss oil-based varnish, polyurethane and Danish oil can last 10 or 20 years, though satin finishes and stains may fail sooner as pigments and flattening agents disable the driers. Water-based coatings and paints can also be viable longer than three years. Shellac, though, can go bad in under a year.
Wash it first with dish soap and water, then lightly sand the old finish with 220-grit sandpaper. Vacuum off the dust, then apply the finish as usual. Apply at least two coats to achieve an even sheen.
Generally, more than 3 coats of poly doesn't do much good. It's really not needed nor recommended. Each additional coat needs to be buffed so you are kind of buffing off half of the previous layer. It's kind of like nail polish where it takes longer and longer to dry and cure for each coat.
ALL oil based varnish and poly varnish will yellow eventually over time. Some yellow less and more slowly than others. Pratt & Lambert 38 is one of the latter and you might want to give it a try. However, if you want a finish that will not yellow you want to use a waterborne clear acrylic.
Polyurethane can be oil- or water-based, and you can use either kind over latex paint; however, oil-based polyurethane tends to yellow as it ages, whereas water-based varieties stay transparent. Oil-based products also dry more slowly than water-based ones, giving you more time to work.
Overview. Minwax® Water Based Wipe-On Poly is a durable, clear finish that combines polyurethane protection with classic, hand-rubbed beauty. Applied with a cloth – no need to worry about drips and brush marks. Great for furniture, railings and trim.
Yes, you can apply a wipe-on poly with a rag.
You can rub out all types of film forming finishes, including shellac, lacquer, oil based varnish and polyurethane, waterbased coatings and catalyzed or conversion coatings. There are three strong reasons for doing so.
Polyurethane is so durable and water-resistant, it has largely replaced shellac and varnish as a wood finish. Originally, it had to be brushed on, but different formulations mean it can now be applied as a spray or by wiping it on with a rag.
Using steel wool or sand paper allows you to create a uniform surface for the next coat of polyurethane, which generally looks nicer, more professionally, etc. In my experience, assuming the finish is dry, there isn't a difference other than the coarseness of the sand paper or steel wool.
Minwax wipe on poly is food safe since it is a clear oil-based finish.
Topcoat with No-Shine PolyurethaneOn the shelf at the paint store, you'll find products that run the gamut from full gloss to semi gloss to satin to matte. They are all water-based products, differing only in the amount of flattening additive they contain.
