TOP 10 Best guns for polyurethane foam

The device of absolutely all prefabricated foam guns is almost the same. However, manufacturers offer variations of these tools. There are plastic, metal, collapsible, cast systems on the market, as well as budget and high-end foam guns. This is the main detail in the repair work associated with the sealing of joints and cracks. We have prepared a rating of the best polyurethane foam guns in 2020.

Pistol selection criteria

In the event that one-time work will be carried out with foam, then you should not buy an expensive pistol. But if the process of using is systematic, you need to consider options for a quality tool. They have a number of design differences that increase the service life, and are designed for convenient use.

1. The design of the pistol. Collapsible systems are much better, as they make it possible to carry out cleaning from foam, thereby increasing the working capabilities of the gun during subsequent use. Teflon-coated metal parts make it easy to remove foam residues. It is good if you have: an adjusting screw, special recesses for the fingers, a dispenser.
2. Material. Cast metal is a much more reliable option, it differs from silumin in weight - cast products are much heavier. Affordable plastic is used for disposable systems, and the combination of alloy and plastic will make it possible to build a mansion or renovate an apartment.

We have selected models that have been noted by multiple users and received high-quality professional ratings. The craftsmen tested these models and gave a quality rating for each of them.
