You need to wait a minimum of 3 days with warm temps before you can topcoat MinWax with a lacquer product.
Lacquer can be used on most woods, but it cannot be used on mahogany and rosewood; the oils in these woods will bleed through the finish. … It cannot be used over other finishes or over oil-base stains or many fillers; the solvents in lacquer will dissolve other finishes and incompatible stains and fillers.
Most wood stains can dry completely in 24 to 48 hours. Some, like General Finishes stains, may only take between 3 and 4 hours. You can then apply the polyurethane coating. However, for caution, you may want to wait 72 hours to make sure it dries completely.
Ideally, lacquer should be applied over the base colour just as the base colour has begun to flash off. This is because adhesion is created when the solvent in the lacquer reanimates the still curing colour coat.

Question: How many coats of lacquer should I apply to wood? Answer: A minimum of three coats work best for ideal longevity and protection. Sand with sandpaper that is meticulously fine in texture. Make sure to wait between each coat.
Despite being available in variances, polyurethane is more durable. It is thick and leaves a strong coating. Lacquer is thin and penetrates the wood surface. It is also durable but susceptible to scratches and discoloration after some time.
Polyurethane, varnish, and lacquer are tried-and-true sealants with excellent waterproofing properties. They’re either brushed or sprayed onto clean, sanded wood and then allowed to dry completely, prior to the piece being lightly re-sanded and recoated.
In general, you should wait between 24-48 hours for the stain to dry before polyurethane. If you don’t want to take any chances or think the stain might not be dry enough, wait an extra day before applying poly.
If you applied the stain correctly, and it still remained tacky, it could be due to rainy weather or high humidity. … In either case if the tackiness doesn’t go away, wipe the wood down with mineral spirits or naphtha to remove most of the stain, let it dry thoroughly, then try again using a fresh can of stain.
Actually, it’s not really to make a dry faster, it’s to give it the best opportunity to dry naturally. A couple of these things are heat and humidity. When the manufacturer does drying tests, they use a warm room with no humidity. These are optimal conditions for a finish to dry, and of course it speeds up the process.
You must scuff-sand each coat to ensure a good bond. Sand too soon and you’ll pull the finish.
Let the base coat dry completely before moving on to the clear coat. It’ll usually take about 30 minutes for the base coat to dry, but depending on the temperature and humidity, it could take closer to 60 minutes. You’ll know it’s dry when it’s smooth to the touch and your fingers don’t drag on it when you touch it.
Lacquer is available for application with either a brush or as a spray. … Brush-on lacquer will dry quickly but is formulated to give you at least a little bit of time to apply and even out the finish. Use a bristle brush, preferably of high-quality natural bristles, to apply the lacquer.
The instructions on the can will indicate that you can apply a water-based clear coat right over an oil-based stain if the stain has thoroughly cured. However, the curing time can be several days, especially with an open-grain wood such as oak where the stain can sit uncured deep in the pores.
Minwax Semi-Gloss Oil-Based Lacquer (1-Quart)
The best alternative method on how to get a high gloss finish on the wood is by using a varnish or lacquer. You can easily spray lacquer but if you are using a varnish then you have a choice between both brushing and spraying. Though, you will be more comfortable with spraying as it takes less time and is an easy job.
No, you can’t apply poly over lacquer as polyurethane won’t bond. The two can’t be used interchangeably because if you put Polyurethane over lacquer, the surface will bubble up and flake over time.
2 coats. To deepen the color, apply a third coat. Optional, for additional luster or sheen a clear protective finish can be applied. Recommended finishes include Minwax® Fast-Drying Polyurethane or Minwax® Wipe-On Poly.
Yes, you can spray “brushing lacquer”–although depending on your gun, you will most likely want to thin it first with lacquer thinner. Keep in mind that spraying is not necessarily faster than brushing. You will have to spray more coats to equal a single brushed coat.
Orange peel is the most universal defect in a sprayed finish. … The most common cause of orange peel is an imbalance between the viscosity of the finish and the amount of air atomizing the liquid as it exits the gun. The thicker the liquid, the more air that is required; the thinner, the less air needed.
You can use a high-quality sponge roller or low nap velour roller to roll the Lacquer on the surface. Make sure you apply thin coats. Applying the Lacquer too thick or re-coating to quickly can cause a foggy-looking effect. Between coats, you may repeat lightly sanding your piece and wiping it with your tack cloth.
Between each coat, allow the lacquer to fully dry, and rough it up with 400 grit sandpaper, wiping dust off before applying the next layer. Three or four coats of lacquer should give you a smooth and shiny finish. The lacquer should be free of dimples, even and smooth.
Although lacquer is a durable finish, it does sustain scratches – especially on tabletops. Most scratches aren’t difficult to level out with fresh lacquer, but you may have a problem matching the sheen of the area you repaired with the rest of the table.
Three years is a safe number, but the truth is that older coatings, properly stored, may be viable much longer, though shelf life varies from one finish to another. Nitrocellulose lacquer can last indefinitely, and even decades-old lacquer is usually just fine.
If finishing a darker wood, such as walnut, mahogany or cherry, then one of the other finishes such as shellac or lacquer is better. … They also make the wood look richer and continue to darken as they age. If drying time is important, shellac and lacquer finishes dry the fastest followed by water-based finishes.
Lacquer is a modern wood finish that is commonly used on high end furniture. It is fast drying, impervious to water, and maintains its transparency as it ages. Lacquer finishes are popular because they don’t yellow with age, protect well against liquids, and require very little maintenance.
If you apply a second, unnecessary coat of stain to wood that is already adequately covered, you risk creating a tacky surface that is prone to early peeling because the second coat is not penetrating the wood surface, but simply laying on top of the first coat of stain.
Wood stain is designed to penetrate into the grain of the wood, not to remain on the surface. If you happen to spread it too thickly, or you forget to wipe off excess, the material that remains on the surface will become sticky.
You can polyurethane over oil-based stain but not over the water-based stain. Other than that, you can polyurethane over gel stain without any issue. But always make sure to let the gel stain surface dry completely before applying the polyurethane layer.
David and Ash agree that hot weather is worse than cold weather for staining wood. Extreme heat causes the stain to dry too quickly, leading to uneven color and brush strokes.
Penetrating wood stains are not intended to be a surface finish. If applied too thickly, they won’t dry properly and will remain tacky to the touch. … To remove excess oil stain from wood, simply apply another coat of stain, allow it to soak in for a few minutes, then wipe it off.
If your coat goes down too thickly, just wait. With time and patience, it will dry. Humid weather – the #1 problem caused by humidity is longer drying times for stains and clear protective finishes. If it’s humid out, you can usually expect the stain or clear finish to take longer to dry than it says on the label.
Yes if you blow air (especially heated air) over various oil-based finishes they will dry faster.

Lacquer and shellac finishes are reversible finishes so it is more important to sand out the “trash” in the finish than a very complete sanding. Always sand with the grain when hand sanding. … When sanding before the final coat, switch to 800 grit paper. Remove all dust before proceeding to the next step.
If you’re hand sanding lacquer, start by wetting the surface lightly and using 320- to 400-grit sandpaper to smooth the surface until you see your desired sheen and finish.
Bubbles are caused by the turbulence created by the brush gliding over the surface much more than from shaking or stirring the finish. The problem is worse if your shop is hot or if the finish and wood are at different temperatures. … To remove bubbles that have dried in the finish, sand them out and apply another coat.
