What is pre-mixed masonry cement repointing mortar?

Pre-mixed masonry cement repointing mortar is a factory-blended dry product — masonry cement (a proprietary blend of Portland cement, limestone filler, and air-entraining agents), fine aggregate, and colour pigment — supplied in 20–25 kg bags, mixed with clean water only on site. The factory-controlled blending eliminates the proportioning errors common in site-mixed cement:lime:sand mortar, delivering consistent colour and strength across large Class 2 strata repointing jobs.

Boral Pre-mixed Masonry Cement Repointing Mortar

Pre-mixed masonry cement repointing mortar — Boral — national supply

System Description

Boral's pre-mixed masonry cement repointing mortar is a factory-blended product combining masonry cement, sand, and colour pigments — mixed with clean water only on site. Boral offers a colour-matched range of repointing mortars in standard shades (cream, grey, charcoal, and other colours) designed to match common brick mortar joints on Class 2 strata facades. The factory-controlled blending eliminates the site batching errors in cement:lime:sand proportioning that cause strength variation and colour inconsistency when mixing from separate components. Each bag is a consistent pre-measured quantity — reducing waste and improving consistency across large repointing jobs. Available through Boral trade centres, Bunnings Warehouse, Mitre 10, and independent masonry merchants nationally. Confirm the AS 3700 mortar class designation and compressive strength from the current Boral product data sheet — masonry cement mortars vary in designation between product lines. Commission a 28-day cured trial panel before approving colour match.

Technical Properties

  • Factory-controlled blending — eliminates site batching errors in proportioning
  • Colour-matched range available — cream, grey, charcoal and other standard colours
  • Add water only — no separate cement, lime, or sand components required on site

Limitations

  • Colour range limited — match against existing weathered mortar and commission a 28-day trial panel before ordering full quantities
  • Higher cost per unit than site-mixed GP cement + lime — pre-mix premium applies
  • Not suitable for soft historic brick — same rigidity and low vapour permeability as all cement mortars

PROCUREMENT SOURCES

Confirm suitability with the current manufacturer TDS before specifying or applying.

Do not confuse pre-mixed masonry cement mortar with:

  • GP cement + hydrated lime site-mixed mortar — the alternative where separate GP cement and hydrated lime are batched on site — more flexible for large volume projects but requires accurate proportioning — listed on the GP cement + hydrated lime mortar page
  • Polymer-modified cement repointing mortar — pre-bagged products with polymer admixtures (Sika, Mapei, Parchem, Ardex) for improved bond and reduced shrinkage — specified for high-movement zones, coastal parapets, and where standard mortar has repeatedly failed — listed on the polymer-modified cement mortar page
  • Natural hydraulic lime mortar — for soft historic and heritage brickwork where original mortar was lime-based — listed on the repointing mortar — lime page
  • Tile adhesive or grout — these are entirely different products for tiling; do not use tile grout for masonry repointing
  • Render repair mortars — polymer-modified cementitious mortars for concrete repair (spalling, delamination, carbonation) — Sika MonoTop, Fosroc Renderoc — not masonry joint mortars
