Overview

Patch. Reprofile. Restore.

Polymer Modified Repair Mortar is a single-component cementitious repair mortar for general-purpose concrete surface repair. The acrylic polymer modification delivers excellent adhesion, low shrinkage, and high freeze-thaw resistance without requiring a separate bonding agent for most applications.

The workhorse product for concrete restoration – used across building maintenance, façade repair, and refurbishment contracts.

Key Features

  • Single-component – just add water
  • Polymer-modified for enhanced adhesion
  • Low shrinkage – minimal cracking on cure
  • Trowel-applied 5–40 mm per coat
  • Compatible with steel reinforcement (alkali pH)
  • EN 1504-3 Class R3 certified
