Frequently Asked Questions

What is polymer repair mortar used for?

Polymer repair mortar is used for concrete surface restoration including spall repair, patch repair, protective overlays, and structural rebuild. Our epoxy mortar achieves ≥75 MPa compressive strength, while polymer-modified cementitious options (≥45 MPa) are more economical for general repairs.

How thick can repair mortar be applied in one layer?

Application thickness depends on the product: epoxy mortar 5–50 mm, structural repair mortar up to 80 mm, and self-leveling mortar 3–20 mm per layer. For deep repairs, our Structural Repair Mortar XQ-SJ-SR can rebuild up to 80 mm without formwork.
