Purpose of Styrofoam:

Waterproof plugging: Repair and plugging of water supply pipeline, sewer and other vulnerabilities.

Usage method and procedure:
first take the foaming gun and clean it with polyurethane cleaning agent to ensure smooth flow;
take another Styrofoam, hold the middle part of the tank body tightly with your hands, and shake at least 15-30 times with force along the horizontal direction of the tank body. Make sure that the prepolymer in the tank is fully mixed;
then remove the protective skin cover of the valve on the Styrofoam thread ring of the gun, remove the cleaning agent on the foaming gun, and install the foaming agent tank on the interface of the foaming gun along the thread;
then hold the handle of the foaming gun tightly, make sure that the material tank is placed above and the foaming gun is below material tank, and open the flow regulating valve at the rear of the foaming gun;
the gun head is aimed at the bottom or inside of the part to be filled, gently pull the trigger and start the construction. It can be adjusted to the appropriate flow through the flow regulating valve behind the foaming gun.
After a can is sprayed, if it needs to be filled, remove the empty can immediately, reinstall the foaming agent according to the method of point ③, and continue the construction.
Note: After the construction is completed, remove the material tank in time and replace it with a special cleaning agent to clean the foaming gun, so as to avoid curing and blocking of residual materials and damaging the foaming gun.
