Polymer-modified cement repointing mortar

Sika Australia supplies polymer-modified cementitious repair and repointing mortars for masonry facade remediation on Class 2 strata buildings. Sika's repointing mortar range includes polymer-modified, pre-bagged products formulated for improved adhesion and reduced shrinkage compared to standard cement mortars. Products in the SikaMonoTop and SikaRep series are typically used for masonry repair and repointing in high-exposure and high-movement locations — parapets, exposed copings, coastal facades, and zones where standard cement mortar has repeatedly failed. The specific current Australian product designation for polymer-modified masonry repointing must be confirmed with Sika Australia technical — Sika product range designations are subject to periodic revision and the current Australian catalogue may differ from international product data. Sika is available nationally through Sika Australia trade branches, Parchem Construction Supplies, and specialist building trade merchants. Confirm mortar class designation (AS 3700), compressive strength, pot life, and colour availability from the current Sika Australia TDS before specifying.

Mapei Australia supplies polymer-modified cementitious mortars for masonry repair and repointing including the Mape-Antique MC product — a polymer-modified mortar specifically formulated for conservation masonry work — and the Mapegrout series for structural repair and repointing in high-exposure applications. Mape-Antique MC is a mineral, pre-bagged mortar modified with polymers and natural aggregates for repointing old and heritage masonry where a softer, more breathable polymer-modified option is required over standard cement mortar. Mapegrout BM is a higher-strength polymer-modified base mortar suitable for structural repair and heavily exposed parapet and pier repointing. Confirm the appropriate product with Mapei Australia technical for the specific substrate and exposure classification. Mapei is distributed nationally through the Mapei Australia trade network and Bayset building materials. Confirm current Australian product names, mortar class designation (AS 3700), and colour range from the current Mapei Australia TDS before specifying.

Fosroc polymer-modified cementitious repair mortars distributed nationally by Parchem Construction Supplies (DuluxGroup) are used for masonry repointing and surface repair on Class 2 strata buildings. Fosroc RepaBuild MF is a fine-grade polymer-modified mortar for surface repair and joint filling, while Renderoc Classic is a pre-bagged polymer-modified repair mortar for base coat repair and repointing applications. Both products provide improved adhesion and reduced shrinkage compared to standard cement mortars, making them suitable for high-exposure repointing applications such as parapets, exposed copings, and coastal facades. Parchem Construction Supplies operates trade branches in most Australian metropolitan and regional centres — providing consistent technical support and product availability nationally. Confirm the appropriate Fosroc/Parchem product for masonry repointing (rather than concrete repair) with the local Parchem branch before specifying — the Fosroc range includes both concrete repair and masonry products which are different formulations. Confirm mortar class designation (AS 3700) and colour range from the current Parchem TDS.

Ardex Australia supplies polymer-modified cementitious mortars for masonry repair and repointing on Class 2 strata building facades. Ardex X 32 is a single-component polymer-modified repair mortar for masonry and concrete repair that can be used for joint repointing and surface repair in high-exposure applications. The Ardex range for masonry applications includes products with enhanced adhesion, reduced shrinkage and improved durability compared to plain cement mortars — making them suitable for parapet coping repointing, coastal facade joints, and locations where standard cement mortar has failed. Ardex products are available nationally through Ardex Australia trade distributors and hardware merchants. Confirm the specific current product appropriate for masonry joint repointing (versus concrete structural repair) with Ardex Australia technical before specifying — the Ardex range spans both masonry and concrete repair applications with different formulations. Confirm mortar class designation (AS 3700), compressive strength, pot life, and colour range from the current Ardex Australia TDS before specifying.
