gun foam and charges him

Many have experienced what a polyurethane sealant, and as far as he is crafty if improperly handled with him.Two stages of expansion followed utjazhki can disrupt even the most seemingly-quality fill, if a little wrong with the dosing of individual portions.By the way, grouting portions recommended for the simple reason that the masses hardening occurs from outside to inside.If the layer is too thick, it is already at a depth of 3 cm under the crust there is moisture deficit is not coming from the outside, voids and sink.

household Dosing cylinders with nozzles in the form of tubes is difficult, due to the very high density of the sealant on output.Disposable gun to spray foam professional can reduce the probability of faults due to the relatively low density sealant output, thereby decreasing the secondary expansion and shrinkage is very low.Important role plays and ease of operations for filling seams and gaps.

ready to work under the gun assembly foam

to use ordinary household bulb polyurethane sealant enough to shake it a couple dozen times, and then install the nozzle and press the valve by turning upside down, so that the gas does not corrode faster foam.However, there is a certain disadvantage - a balloon should be to empty all at once.Otherwise, after a short time the mass of the tube and valve hardens, and all that was left inside, throw together with capacity.

nozzle diameter for domestic cylinder is approximately 6.5 millimeters, due to which gas is discharged with a slight pressure and poor foams mass, leaving it too dense.

gun under mounting foam uses several different bottles, which can not be applied with a household head.The special thread on the site of the valve allows the screw container with foam in a special slot at the top of the gun.With an installed charge tool becomes a weapon similar to paintball.After pressing the trigger gun, as expected, he makes a shot, releasing from the bore foaming sealant lump.It is noteworthy that one professional balloon can be used repeatedly.

How to make the right choice for gun foam?

Like any other tool, Gun for construction foam spraying represented by a large number of models.Best cheap - plastic.However, the choice for gun foam should be based on practicality, and so preference is given to the most reliable tools.The operating principle of each of them is the same - there are two valves, is connected to the upper primary filling tube, it departs from the strip, which is located inside the shaft, the second valve unlocks after pulling the trigger.

Screw balloon on a special ring, to turn away to the limit, it is screwed until you hear a hissing sound, and that the gun is loaded, foam filled chamber within, and from the front of the work it separates the second valve.So, if you use the tool repeatedly, sooner or later, all channels are tightly clogged with sealant, despite regular cleaning.Therefore it is better to choose a gun, completely disassembled.This will give the opportunity to thoroughly clean every detail and bring an instrument of labor in readiness before the next fill joints and cracks.

However, such a tool would be more expensive, and not folding plastic will cost you 20 or even $ 10.Try check valves to purchase tools, it can be done with a special cleaning liquid (acetone), which is also poured into the cylinders under pressure .Screw a bulb and take a few test "shots".If after filling the channels of the front flap is not oozing liquid, so everything is in order.
