Usage instructions

Before construction, the surface to be worked on should be cleaned and sprayed with water to moisten it. Shake the material tank up and down for about one minute, then invert it and install it at the connection port of the spray gun. Rotate counterclockwise to open the flow valve and adjust the flow rate. When filling the vertical gaps, spray from bottom to top. The surface will be solidified in about 10 minutes, and can be cut in about 60 minutes. Use a small knife to remove the excess foam, and then treat the surface with cement mortar or paint.

Construction Notes

Before construction, remove the floating dust and oil stains from the surface, and spray a little water on the surface. When filling vertical gaps, do it from bottom to top. Please clean the spray gun immediately with the dedicated cleaning agent after use. This product does not protect against UV rays, so other protective materials should be applied on the foam surface.
