Which gun is better for polyurethane foam? Which gun to choose?

Foam is one of the most popular building materials widely used in decoration and repair. In view of the characteristics of this composition, it is very important to know which gun is best for polyurethane foam. Modern manufacturers offer a wide selection of devices that will make work easier and more convenient.

What to consider when choosing

To begin with, we note that today you can buy a gun at a price of 200 rubles or more. To choose the right and stable working product, you should pay attention to a number of features:

1. Material. Modern models are made on the basis of metal, plastic powder mold or metal, which is coated with Teflon. The lightest and most convenient products to use are created on the basis of powder spraying.
2. Gearbox. Ideally, it should be made of cast metal and coated with a layer of Teflon. Such a coating is not accidental: it does not adhere to the foam; moreover, it is always easy to clean. A plastic gearbox is also good, especially if it is from a domestic manufacturer.
3. Body. Which gun for polyurethane foam to choose? Pay attention to the housing. Ideally, it should be metal, however, all-plastic models are pretty good. True, in some products, plastic is so poor in quality that it corrodes under the influence of foam or a cleaner.
4. Collapsibility of models. Modern guns for working with polyurethane foam can be disassembled or be integral. The main feature of collapsible models is the ability to decompose them into parts and clean.
5. Needle material. Avoid buying a gun that is simply covered with paint: it will peel off immediately, so working with it will be inconvenient. Ideally, the needle should be made of brass and steel.
6. The presence of a dispenser. This is an important functional element because it can be used to control the amount of polyurethane foam supplied.

Check before purchase

To understand which gun is best for polyurethane foam, several devices should be tested. And you need to do this before buying. The check is the simplest. First you need to check the operation of the starting mechanism: since the pressed products are delivered to the stores, gas under pressure is inside them. As soon as you pull the trigger, you will hear "zilch": this suggests that you can safely take the gun!

If there was no characteristic sound, then you can buy the cheapest bottle of foam cleaner, put it on the gun. Pull the trigger a couple of times, listen to the sounds - there are no gaps in the connections of the gearbox or the fitting with the valve. Check gun for spraying foam in different modes. So you can test his work more thoroughly.

Cheap or expensive

Before you buy a gun, decide for yourself for what purpose you need it. If you just finish window or doorways, then there is no point in buying a professional unit - you can get by with a budget model. If you need a gun seriously and for a long time, to solve complex and constant problems, choose the one that has a metal body and a Teflon coating. At the same time, pay attention: a good gun for polyurethane foam is characterized by high-quality assembly and fit of every detail. The advantage of such models is the ability to assemble and disassemble.

What are the benefits

Modern brands offer a large selection of sealants with a plastic applicator, but not all of us are comfortable using them. In this regard, a foam spray gun is a better solution:

1. It can be configured so that the foam comes in a specific dose. It is also possible to change the supply of material depending on what the depth and width of the seam will be.
2. As soon as the trigger is released, the foam ceases to flow.
3. A special needle placed in the housing prevents air from entering the device. That is, at any time, you can interrupt the work, while the foam does not freeze in the cylinder.
4. If you are considering which gun for mounting foam is better, pay attention to the models in which you can change the cylinders. This expands the scope of work, in addition, there is no need to disassemble and clean the device.
5. Convenience is also a positive aspect of pistols. To use it, you need to use only one hand.
6. Most manufacturers offer models in which parts are made of metal. This guarantees the reliability and resistance of products to mechanical stress.

Application features

Which gun is better for polyurethane foam? We will consider popular brands a little later, but for now we will determine what are the features of the use of these units. Using them is very simple:

1. First, the gun is attached to the cylinder, while its nest should be lubricated to ensure the tightness of the connection.
2. The cylinder is turned over, the screw is installed in such a position that the foam flow is optimal. The foam output is controlled either by pressure force or by a screw.
3. First pressing the trigger release air. Foam application should be uniform and accurate from the bottom up, while the joints do not fill the gap to the end.
4. During a break in work, store the cylinder vertically.
5. At the end of work, disconnect the cylinder, wash off the remaining foam from the gun, and do it quickly - so that the material does not dry out.

Remember the principles

To choose a good gun for polyurethane foam, you need to have an idea of ​​how it works. In addition, the quality of its operation depends on the thoroughness of the preparation of the treated surface. If there are splashes from the foam, you can remove them with simple acetone or a special foam liquid. After cleaning, the surface is abundantly wetted with water, so that the foam does not creep and does not stick. Before use, the cylinder should be heated to a temperature of 20 degrees.

If you are installing elements that are highly susceptible to deformation, choose a special foam that has a low level of foaming. It shows resistance to mechanical damage, has small pores in size, therefore, it is characterized by low water absorption. After hardening, the foam should not be thicker than 3 cm, and it should not be touched until the layer has completely hardened.
