Product Overview
SikaMix Plus Mortar and Plaster Admixture supplied as a ready-to-use brown liquid. This admixture is designed to modify and enhance the performance of cement-based mortars and plasters, providing improved plasticity, cohesion, and long-term durability.
Acting as both an air-entraining and plasticising agent, it introduces finely dispersed air bubbles into the mix when added to gauging water, producing smoother, more workable mortars and renders.
The result is an easier-to-handle, more consistent material with reduced cracking, shrinkage, and improved frost resistance. SikaMix Plus is CE marked and tested in accordance with EN 934-3 as an air-entraining/plasticising admixture for masonry mortar.
Features & Benefits
- Improved workability: Creates a smoother, more cohesive mortar with enhanced handling, spreading, and finishing qualities.
- Reduced water demand: Lowers the amount of water required to achieve target consistency, contributing to increased density and strength.
- Enhanced strength: Supports improved compressive and flexural performance in hardened mortars and plasters.
- Improved frost resistance: Introduces micro-air structure to enhance resistance to freeze–thaw cycles.
- Minimised cracking and shrinkage: Reduces drying and thermal cracking, including fine surface crazing.
- Reduced efflorescence: Limits the formation of white salt deposits on masonry surfaces.
- Non-corrosive composition: Contains no chlorides or aggressive substances, ensuring safety for embedded steel reinforcement.
- Improved adhesion: Promotes superior bond strength between mortars or plasters and various substrates.
- Controlled setting behaviour: Aids in achieving consistent setting times under variable site conditions.
- Economical use: Concentrated formulation provides efficient performance at low dosages.
- Ease of application: Supplied ready for direct addition to gauging water for simplified site use.
- Consistent quality: Assists in producing reliable, uniform mortars and renders across multiple batches.
- Product form and colour: Ready-to-use brown liquid admixture for addition to gauging water.
Applications
- Bricklaying and blockwork mortars: Produces workable, durable mixes for high-quality laying of bricks, blocks, and masonry units.
- Renders and plasters: Generates smooth, easily applied coatings for internal and external use.
- General masonry mortars: Enhances workability and durability in all site-mixed mortars exposed to varying conditions.
Installation Guidance
- Dosage recommendation: Add 125–250 ml of SikaMix Plus per 50 kg of cement, depending on mix design and required workability.
- Preparation of solution: Add the measured quantity of SikaMix Plus to clean gauging water before introducing the liquid to the dry mix.
- Mixing procedure: Combine the prepared solution with cement and aggregate in the mixer, following normal mixing practice until uniform consistency is achieved.
- Direct addition: Do not add SikaMix Plus directly to dry cement or sand.
- Trial mix verification: Carry out trial mixes to confirm optimal dosage for site materials and conditions.
- Substrate preparation: Ensure all surfaces are clean, sound, and suitably dampened prior to mortar application.
