Today it is already difficult to imagine any repair and construction work without the use of polyurethane foam. And in each case, it will be important to use not only the proposed solutions based on the cylinder and the available tubes to it, but also to resort to the use of polyurethane foam using a gun. And then a logical question arises - a gun for polyurethane foam - which one is better to choose. This issue should be taken seriously, because the use of a pistol will significantly simplify work at height and will allow you to perform better work on foaming the seams and the formed contour.
Features of technical use and advantages
Before using a gun for polyurethane foam, it is important to decide what it will be needed for and what advantages it will give when carrying out this type of work. If we are talking about one-time foaming of the space between windows or doors, then you should not purchase a gun and it will be enough to use the proposed set of tubes and a can of foam. But if the frequency of the installation work carried out is performed more than once, then the use of a gun will allow you to get much greater productivity and create catalytic criteria for its use.
And here it is worth highlighting a number of advantages that will allow you to get a familiar and so familiar gun for polyurethane foam, namely:
- Profitability. Achieved by uniform foam distribution and detailed applied pressure. This gives an advantage of 3 times, allowing not to spray an excess amount of polyurethane foam on the surface of the seam or space, when installing any of the elements in the existing opening.
- Practical and productivity-enhancing. By using a gun, the installation performance can be improved. By creating the best criteria for foam movement and a detailed approach to the process. You can more easily squeeze out the foam and fill the seam space, and not the wall sections or product elements.
- Relevance for detailed sealing and narrow spaces. Using a pistol, you can approach the supply of foam in more detail and introduce it even into the most difficult to reach places.
- Reuse the foam cylinder. With the correct use of the pistol. You can reuse the remaining foam, which cannot be done by simply taking a can of foam.
These criteria make it possible to apply a gun for polyurethane foam, taking into account the specifics of the work and certain volumes of seams or the existing space for foam. It should be noted that this kind of device will allow a universal approach to work and exclude significant defects in the joints of individual products.
Design features of the tool
Before choosing a tool for construction work, it is important to study in detail its design features. This will eliminate the choice of a poor quality and suitable solution for each of the cases. and in the case of a gun for polyurethane foam. Each of their pistols has separate elements, namely:
- Housing. This element can be made of both metal and plastic;
- The metal barrel allows you to create a concentrated jet of foam and a needle rod is located inside it;
- Lever. On its surface there is a trigger that drives the exhaust valve;
- Tip. Due to the selection of this element, you can select the profile and amount of sprayed foam;
- Adapter. Its feature will be the fastening of the foam cylinder and the possibility of feeding a pistol into the system. In this case, the adapter (reducer) has a valve that controls the movement of foam in portions;
- Adjusting screw. This element allows you to control the movement of the trigger and the force with which foam enters the gun barrel.
Rules for the use of a foam gun
With the correct use of any construction tool, we can talk about its durability. In this case, the gun for polyurethane foam is no exception, and if you take into account the yard of the rules and follow them, then mono will talk about continuing its perishable use in construction and installation work. In this case, it is important to take into account the safety of work, because the foam in the cylinder is easily flammable and, if it gets on the skin or if parts of the body are opened, it can cause irritation. Therefore, it is worth considering a yard of rules, namely:
- Before using a new can of foam, shake it thoroughly. Then screw the top of the valve to the gun vertically. Then the pistol is turned over to the working position, and the work is performed with a firm grip on the pistol handle.
- The surface on which the polyurethane foam will be applied must be free of debris and dirt. It is best not to apply the foam at high ambient temperatures, as this can affect the bonding process to a heated surface.
- The increase in the intensity of the foam supply should be carried out by screwing in the control screw, and not by pressing the trigger harder. It should be understood that the pressure generated will allow the foam to escape quickly, for this it is worth preparing the volume and space for foam distribution. This will eliminate the loss of material and poor quality work.
- All work carried out should be carried out with gloves, and with the presence of overalls, will protect the opening of the body, so that the foam does not get on the skin. In no case should you remove excess foam by hand, for this you should use a rag or spatula.
- To carry out the work of foaming the space, it should be from top to bottom, so that you can control the placement and distribution of foam in the seams evenly. It will also allow you to see the result of foaming as you move the gun nozzle.
- To clean the gun after completing work, you should use a special tool. This will allow the device to remain in working order, even with a long foaming process and periods of inactivity.
- In the absence of work or minimal interruption, it is worth leaving the balloon upright, avoiding direct sunlight.
- When reusing the cylinder and the remains of the foam, it is worthwhile to resort to rinsing and the foam supply area, this will eliminate the cylinder jam and give a reason to use the material completely.
During storage, it is unnecessary to remove the cylinder, this allows you to keep the instrument in working order for many months.
The main criteria for choosing a foam gun
The most important criteria for the choice of equipment will be its reliability. Both the workflow and the criteria for practical application will depend on this point. To do this, you should carefully consider the choice of product. And here it is worth giving preference to methodical products, which will allow not only to ensure tightness, but also the best process of moving the polyurethane foam, without corroding the main elements of the product.
It is also worth noting the item with the selection of a light pistol, which will allow less hand fatigue and perform large amounts of work without rubbing calluses and more securely in the hand. Giving a reason to practically perform any volumes. in addition, watch the video on choosing a foam gun.
