Q. What is the best way to choose a shine?

The shiny option is a personal preference. Satin gloss finishes reflect less light and glossy gloss finishes reflect more light.

Q. Is one shine more durable than the others?

NO. The additives that distinguish satin from satin and luster do not affect the durability of the surface.

Q. What can be done to prevent blisters in the finish?

There are four options. Mix the can first, do not shake. Second, use a high quality natural bristle brush. Third, work the varnish into the wood, but don't create too much foam. Fourth, before stopping, "wrap" the surface and gently run the brush at a 45-degree angle down the length of each board in one continuous motion. This will burst and smooth any bubbles that may have formed.

E. Must be Minwax®Polyurethane that dries quickly between coats?

Yes. Light sanding (#220 sandpaper) will remove any fine dust particles that may have settled on the still-wet surface. Gentle rubbing will also help rub the surface, improving adhesion of the inner layer.

Q. Why Minwax?®Does quick drying polyurethane sometimes take longer to dry than the instructions say?

The drying time is influenced by the moisture content of the air, the air temperature and the layer thickness. In high humidity, low temperature or thick layers, the film will take longer to dry.

Q. What is the best way to determine how many coats of Minwax to apply?®Fast drying polyurethane?

If you look closely at the wood in bright, direct light, you should not be able to see any dry spots. In this case, an additional coat of paint is required to protect the wood.

Q. Does Minwax work?®Does fast drying polyurethane need to be waxed?

NO. The wax provides an extra layer of protection but prevents the application of an extra layer of Minwax®Fast drying polyurethane in the future without first removing the wax. Instead, we recommend using itMinwax® wood cleanerto keep the wood clean and beautiful.

WARNING!Removing old paint by sanding, scraping, or other means may produce lead-containing dust or fumes. Exposure to lead dust or fumes can cause brain damage or other adverse health effects, especially in children or pregnant women. In order to control exposure to lead or other hazardous substances, the use of appropriate protective equipment is required, e.g. B. Properly fitted respirator (NIOSH approved) and appropriate containment and cleaning up. For more information, call the National Lead Information Center at 1-800-424-LEAD (in the US) or contact your local health authority.


  1. The surface must be dry and free of old paint in poor condition, paint, wax, grease, varnish, dirt or other foreign matter.
  2. Sand to get a smooth, even surface. Remove any dust with a cloth soaked in mineral spirits.
  3. Stir in Minwax®Quick-drying polyurethane before and during use to prevent settling at the bottom of the container. Mix so that the product rotates from the bottom to the top of the box. NEVER MOVE.
  4. Apply a thin coat of Minwax®Quickly dry polyurethane with a good quality natural or foam brush.
  5. Leave to dry for 4-6 hours. Then lightly sand the entire surface with fine sandpaper (220 grit) to ensure an even finish and good adhesion. Remove all dust.
  6. Apply second layer. If a third coat is desired, repeat step 5 prior to application.
  7. Leave the last coat on for 24 hours before light use.

When using on wooden floors, use a lambswool or synthetic pad or natural bristle brush and keep the tip wet to avoid marking your knees. For maximum durability we recommend three coats. Avoid heavy traffic and furniture changes for 72 hours after the last coat of paint. Do not pull when changing furniture. Do not lay carpets or clean floors for 7 days.

CLEAN UP:For easy cleaning, use mineral spirits or paint thinner.

COVER:Approximately 125 square feet per quarter.

Note: The above drying times are based on good ventilation, a temperature of 25°C and a relative humidity of 50%. Lower temperatures, higher humidity, lack of air circulation or applying thick layers will increase the drying time. Always test the adhesion between layers. Do not rub or reapply if the surface is sticky. A slight orange discoloration may occur when applying polyurethane to light wood surfaces. For best results, always collect the sample from an inconspicuous area. For light wood surfaces we recommend protection withMinwax® Polycrylic® protective coating.

Aerosol instructions

WARNING!Scraping, sanding, or removing old paint can release lead dust. Lead is toxic. Contact the National Lead Information Hotline at 1-800-424-LEAD or sign upwww.epa.gov/lead.

  1. Protect adjacent areas from spray. (Wet overspray can be removed with mineral spirits.)
  2. Hold the container vertically 12 inches from the surface. Fully depress the button and spray in smooth, sweeping motions, slightly overlapping strokes. Apply enough material to untreated wood to seal open joints, edges and end-grain surfaces.
  3. Apply thin layers to avoid bleeding and loosening. Repaint within 2 hours. If that's not possible, wait at least 72 hours, then lightly sand and repaint.
  4. Apply at least three coats to untreated wood and two coats to previously treated surfaces.
  5. Leave the last coat on for 24 hours before normal use.

For semi-gloss or semi-gloss gloss only:Shake vigorously for two minutes. Shake occasionally for 10 seconds during use.

Note:Drying times above are based on a well ventilated temperature of 77°F and 50% relative humidity. Lower temperatures, higher humidity, lack of air circulation or applying thick layers will increase the drying time. Due to its orange properties, application on white or pastel stains is not recommended. Instead of this,Minwax® Polycryl-Schutzlackrecommended. Always do a spot test in an inconspicuous area to ensure satisfactory results.

Care of the nozzles

  1. After each use, clean the valve by turning the container upside down and spraying until only clear gas comes out.
  2. 2. If the spray button is clogged, wear eye protection and wipe the button opening with lacquer thinner. DO NOT insert a needle into the spray button opening.

Clean up:For easy cleaning, use paint thinner and follow the manufacturer's safety instructions.
