LCMOLDS Precast Concrete Railing Molds For Balcony

Prefabricated raw materials (concrete, silica gel, plaster, etc.), molds, release agent(for Plastic Molds only),gloves, goggles, scales, mixing tools, support, operating instructions, etc.

These will be better to help you complete the project.

Usually we often talk that the mold release agent is mainly used in plastic(ABS, PP) molds. Before pouring, it should be applied on the inner wall of the mold first. The advantage is that it is convenient to demould after the prefabrication is completed.

Molds made of other materials, such as silicone molds, are not suitable.

Concrete needs to be mixed, so you must control the ratio of various raw materials. During the pouring process, the construction should be done slowly and at a constant speed. When necessary, a vibrating table or a vibrating rod is required to remove the air bubbles in the concrete. After completion, wait for the concrete to solidify and form, depending on the temperature or environment, ordinary concrete takes 4-12 hours.

For the demoulding of large-sized concrete blocks, you can use a rubber hammer to lightly hit all angles of the mold, and the finished product will fall off naturally-provided that the mold release agent has been applied to the inner wall of the mould.

After the finished concrete is demoulded, its strength is not fully hardened, so it must be placed in a ventilated place to dry naturally (it takes about 12-24 hours). Note: Prohibit sun exposure and rain.
