What is used to block the gap between the heating pipe and the floor?

If the heating pipe has a sleeve, we can block the hole in the wall with cement mortar. When we fill the hole in the wall, we need to clean it up first, and then fill the hole with cement mortar. After the hole is filled, you can brush a layer of waterproof paint and then decorate the wall. Or we can block the hole in the wall of the heating pipe with plaster.

You can also use flame retardant foaming agent to fill the holes in the wall. According to experts from Qijia. Com, the combustion-supporting foaming agent can be used in the range of-10 to 80 degrees Celsius. The temperature of hot water in the liquid circulation system is about 60-80 degrees Celsius; Therefore, when we use flame retardant foaming agent to fill the heating hole, there will be no hot melt phenomenon; Moreover, the flame-retardant foaming agent has good elasticity and will not affect the thermal expansion and cold contraction of the heating pipe.

When we use flame retardant foaming agent to fill the wall hole of heating pipeline, we should clean the wall hole first, and then fill it with foaming agent. Usually, the injection amount of foaming agent is two-thirds of the filling volume. After the foaming agent is cured, the corresponding foaming agent is removed with a knife; Finally, we treat the wall with cement mortar.
