Instructions and Steps<t_XXXXXXXXX> <t_XXXXXXXXX>
First, take the foam gun and clean it with polyurethane cleaner to ensure it is smooth;
Take more foam adhesive, tightly hold the middle of the can, and shake it horizontally along the can body at least 15–30 times, ensuring the prepolymer inside is fully mixed.
Then remove the protective cover from the valve on the gun-type foam thread ring, take out the cleaner from the foam gun, and attach the foam tank to the interface of the foam gun along the threads;
Next, grip the handle of the foaming gun tightly, ensuring the material tank is positioned above, with the foaming gun below the material tank. Open the flow adjustment valve at the rear of the foaming gun;
The tip of the gun is positioned at the bottom or interior of the area to be filled. Simply pull the trigger gently to start the process. The appropriate flow rate can be adjusted via the flow regulator valve behind the foam gun.
After one can is used up, if filling is still required, the empty can can be removed immediately, and the foaming agent can be reinstalled according to point ③, then the work can continue.
Note: After construction is completed, promptly remove the material tank and replace it with a special cleaner to clean the foam gun, so as to prevent residual materials from solidifying and clogging the foam gun.
