These are important about polypropylene engineering fibers!

(1) Application of polypropylene engineering fibers: various ready-mixed mortars, such as: leveling mortar, plastering mortar, thermal insulation mortar; masonry mortar, caulking putty, exterior wall coating, etc.

(2) The amount of polypropylene engineering fibers: the use of polypropylene engineering fiber generally does not need to change the mix ratio of the original design. The general dosage per cubic meter of mortar is 0.9-1.5Kg, and the recommended dosage is 1.0Kg per cubic meter of mortar.

(3) Note: The fiber is only used for crack resistance. After blending, the addition amount of various other additives in the original mortar mix ratio cannot be changed.

(4) Input and agitation of polypropylene engineering fibers: polypropylene engineering fibers and cement should be stirred together, and the fiber should be floated at the top.

(5) Testing of polypropylene engineering fibers strength: the addition of polypropylene engineering fiber generally does not affect the strength of the structure, but the mixture should be verified by experiment before each project is used for the first time.

(6) Finishing pressure surface of polypropylene engineering fiber: When the mortar is closed, steel or iron trowel should be used as much as possible. The wooden trowel is not smooth enough to hook out the fiber.
