What Is SikaMix Plus?
SikaMix Plus is a ready-to-use, brown liquid admixture that modifies and improves the properties of cement-based mortars and plasters.
It functions as an air-entraining and plasticising agent. When added to the gauging water, SikaMix Plus introduces microscopic air bubbles into the mix. This increases the plasticity, cohesion, and workability of the mortar or plaster, which in turn alters its handling and application characteristics.
SikaMix Plus also influences the properties of the hardened material, improving aspects such as frost resistance and durability. The product is CE marked and complies with EN 934-3 as an air-entraining/plasticising admixture for masonry mortar.
Applications
- Bricklaying & Blockwork Mortars: Creating workable mortars for the high-quality laying of bricks, blocks, and other masonry units.
- Renders & Plasters: Producing smooth, cohesive, and easy-to-apply mixes for internal and external rendering and plastering, suitable for various coatings.
- General Masonry Mortars: Enhancing any site-mixed mortar where improved workability, durability, and frost resistance are desired.
Benefits
- Improved Workability: Produces a smoother, more pliable 'fatty' mortar that is easier to handle, spread, and finish.
- Reduced Water Demand: Allows for a reduction in the amount of water needed to achieve desired consistency, which can lead to increased final strength and density.
- Enhanced Strength: Contributes to improved compressive and flexural strength in the hardened mortar or plaster.
- Improved Frost Resistance: Increases the resistance of the cured mortar or plaster to freeze-thaw cycles.
- Minimises Cracking & Shrinkage: Helps to reduce the tendency for cracking (including the "butterfly" effect) and crazing.
- Reduces Efflorescence: Aids in minimising the unsightly white, powdery deposits that can appear on masonry surfaces.
- Non-Corrosive: Formulated to be non-corrosive to embedded steel reinforcement as it does not contain chlorides or other corrosive substances.
- Improved Adhesion: Promotes better bonding of mortars and plasters to substrates.
- Optimised Setting Time: Can contribute to more controlled setting characteristics.
- Economical Usage: Highly concentrated formula ensures cost-effective application.
- Ready & Easy to Use: Supplied as a ready-to-use liquid for straightforward addition to the mix.
- Consistent Quality: Helps produce mortars and plasters with greater consistency and reliability.
Compliance & Standards
- Conforms to EN 934-3:2009+A1:2012 as an air-entraining/plasticising admixture
- CE Marked
Dosage & Usage Instructions
Recommended Dosage:
- The typical addition rate is 125ml to 250ml of SikaMix Plus per 50kg of cement. The exact dosage will depend on the desired degree of plasticising/air entrainment and the specific mix components (sand type, cement type).
- An alternative guide: Approximately 0.125 Litres (125ml) per 25kg bag of cement.
- For larger mixes: 1 Litre of SikaMix Plus added to 200 Litres of gauging water is generally sufficient for gauging approximately 4 x 50kg (200kg) of cement for mortar or render mixes.
Mixing Instructions:
- SikaMix Plus should always be added to the gauging water before the water is mixed with the cement and sand.
- Measure the required amount of SikaMix Plus and add it to a known quantity of clean gauging water. Mix briefly.
- Add this water/admixture solution to the cement and aggregate in the mixer, and mix according to standard practice until a consistent, workable mortar or plaster is achieved.
- Do not add SikaMix Plus directly to the dry cement/sand mix.
- Trial Mixes: It is recommended to carry out trial mixes to determine the optimum dosage for specific materials and site conditions.
Note on Substrate Preparation: While SikaMix Plus enhances the mortar, the mortar itself should be applied to properly prepared substrates. For instance, concrete surfaces should be clean and sound; stone substrates should have friable particles removed. Substrates should typically be saturated with water without standing surface water before mortar application.
