There are many methods to spray lacquer, including gravity-fed spray gun, HLVP, and pre-catalyzed lacquer. To spray lacquer effectively, you need to follow certain guidelines and use the appropriate equipment. This article will teach you about spraying lacquer and its various methods. This article is written by an experienced painter, so you can expect the results you are looking for.
If you’re a DIYer and want to learn how to spray lacquer, an HLVP sprayer is an excellent option. The airflow of an HLVP sprayer is vital to atomizing the paint properly and to cooling the motor faster. There are many benefits to owning one, but be sure to research the power and capabilities of each model before you make the purchase. Read reviews or contact the manufacturer to find out what features it can handle.
The power consumption of an airless sprayer is not a big issue with an HVVP sprayer, but it will require a lot of power to spray lacquer. An airless sprayer will also result in waste when using lacquer, and the high-pressure HVLP sprayer is ideal for this. The size of the tip is important, too: an HLVP sprayer can use a 1.3-mm tip, which is ideal for small jobs where atomization is essential. HVLP systems can spray lacquer with low pressure using a stainless steel piston to push the paint through.
The HVLP spray gun and the lacquer can be mixed together. A spray gun with a wide nozzle is best for lacquer, as it can spray with a higher viscosity than a standard paint gun. Besides spraying lacquer, an HVLP spray gun is useful for spraying shellac, nitrocellulose lacquer, or other types of finishes. Using an HLVP spray gun with a nozzle that is large enough to fit the lacquer helps prevent bubbles.
The best HVLP sprayer for spraying lacquer is the Fuji Semi-Pro Gravity Spray System. It is the best sprayer for beginners, as it produces a high quality polished finish. It has a high-quality motor and gravity feed cups. It can handle continuous use, too, which is essential for lacquer projects. Unlike many HVLP sprayers, this model also produces a high-quality clear coat.
If you’re considering switching to a pre-catalyzed lacquer, you’re not alone. Many pre-cat lacquers are KCMA tested, including Mohawk’s Duracoat. But these pre-catalyzed lacquers are more sensitive to exposure than post-cat lacquers and, as a result, they can sometimes fail to cure. Often, this is a result of repeated exposure to the elements. It is important to remember that while the catalyst improves the durability of the coating, it also limits the flexibility of the final product. Over-building the final finish may result in problems with adhesion and cracking.
Pre-catalyzed lacquers are a great choice for low-traffic areas, since they are very durable and food-safe. They resist water, alcohol, and most foods. Trade Coatings Pre-Catalyzed Lacquer is also easy to apply, isocyanate-free, and remarkably easy to repair. You can use it to paint on a variety of surfaces, including concrete, masonry, and wood.
The downside of lacquers is that they don’t hold up as well as other wood finishes. While humidity is not a concern in Arizona, the humidity will eventually trap moisture, resulting in “blushing,” a problem known as bubblegum. As a result, spraying lacquer on a humid day can cause problems. In Arizona, for example, spraying lacquer on a humid day can cause the paint to blot and crack.

Using a gravity-fed spray gun
Using a gravity-fed paint sprayer is better for small-scale projects. This type of spray gun does not require any pre-pressurized lacquer, and gravity helps feed the paint evenly. The only advantage is that it does not require large canisters and wastes less lacquer. Despite the disadvantages of gravity-fed sprayers, many people find them beneficial.
While using a gravity-fed spray gun, it is essential to follow the manufacturer’s instructions. If you’re using nitrocellulose lacquer, make sure that the sprayer is set at the lowest setting. In case the gun does not have a low-flow setting, you may need to adjust the spray nozzle to lower the pressure. The spray gun should be held at an angle of eight to 14 inches away from the surface.
A gravity-fed spray gun has two interchangeable nozzles. The smaller one is designed for delicate work, while the bigger nozzle is for thicker substances. Moreover, the spray gun comes with a revolving system that allows you to adjust the nozzle size easily. As a result, you can achieve a high-quality finish on a variety of projects with a smaller gun and a bigger one for larger ones.
The other advantage of gravity-fed guns is that the liquid does not have to mix. You can even mix up the material yourself. This is a great advantage for lacquer and urethane because they have different atomization properties. They’re also less messy than airless sprayers, which can be problematic. Also, gravity-fed guns won’t create waste or contribute to excessive amounts of waste.
Adjustments to spraying lacquer
If your lacquer is too thick, you may need to add a bit of water. Always mix the fluid thoroughly before adding more. Lift the mixing stick and look for worm casts. If you see any, your Lacquer is too thick or there is too much water. To ensure the best results, mix the lacquer before spraying it onto the surface. To make the best adjustments to spraying lacquer, follow the following steps:
The most important adjustment to make before spraying lacquer is to determine the humidity level in the room. Spraying lacquer in a high-humidity environment can cause the lacquer to blush. Spraying early in the morning will yield the best results. You should also keep your spray gun moving at all times. The consistent flow of the lacquer is essential to achieving an even finish. The final coat should have a little overlap, but you should not let it affect the look of your lacquer.
A retarder is an additive to lacquer that can reduce the quality of the finish. Retarders prolong the drying time, which can cause potential problems with the lacquer. A sanding sealer, on the other hand, is a lacquer that contains ground glass particles. This reduces the reflectivity and makes the lacquer finish look less appealing. Finally, there are the different types of finishes available: gloss, satin, and matte lacquers. The latter two types of lacquer have added elements and colors to them. They tend to give the lacquer finish a dull appearance and reduce its clarity.
The first adjustment to spraying lacquer is to determine the desired sheen. Many lacquers have different sheens, and some work better straight out of the can. However, a glossy finish is desired. You should consider the sanding process and the humidity level before spraying. Besides the sheen, you should also consider the flowout of the lacquer. To ensure a glossy finish, you should also adjust the amount of solvent you use.
Cleaning out spray tips and nozzles
When spraying lacquer, you should thoroughly clean the nozzles and tips of your spray gun to prevent the buildup of varnish. Lacquer is a thick and sticky liquid, and any buildup will clog the spray gun’s nozzles and tips. Not only can this mess result in an uneven application, but it can also damage your paint canister. To avoid this problem, cleaning the spray tips and nozzles regularly is essential.
First, be sure to clean your spray canister thoroughly. If it is not big enough, you can always buy larger canisters from the manufacturer. Make sure to check the thread size of your spray canister and the pressure rating of the lacquer canister before purchasing. Cleaning the sprayer is one of the least favorite tasks that everyone has to do, but it is an essential part of lacquer spraying.
The spray nozzle itself can be cleaned by filling a small container with a cleansing agent. Once the solution is removed from the spray nozzle, you should turn the spray nozzle in the opposite direction to reorient it in a reversed position. In this way, you can use the same spray nozzle again. Once you are satisfied with the results, you can replace your spray tip.
When cleaning your spray gun, remember to use high-quality lacquer that is pre-pressurized to prevent dripping. The lacquer should be at least two millimeters thick before it reaches the spray tip. If you choose the wrong lacquer, it will end up in splatters on the painted surface. Clean the tips and nozzles regularly to prevent the buildup of lacquer.
