SikaMix Mortar Plasticiser 5L
SikaMix Mortar Plasticiser 5L is a high-quality liquid admixture developed to improve the workability and consistency of cement-based mortar. Suitable for a wide variety of masonry and construction tasks, it helps produce smoother, more cohesive mortar that is easier to mix, spread and finish.
It is ideal for bricklaying, blockwork, pointing and rendering projects, making it a practical choice for professional builders, bricklayers and experienced DIY users. The generous 5-litre container is well suited to larger projects or regular trade use.
Improves mortar workability
Mortar needs to be workable enough to spread easily while maintaining the body and consistency required to support bricks and blocks. SikaMix Mortar Plasticiser introduces microscopic air bubbles into the mix, helping improve its handling characteristics without relying on excessive water.
The resulting mortar is smoother and easier to work with, allowing it to spread more consistently across bricks and blocks. Improved workability can make it easier to achieve full and even joints while reducing the physical effort required during application.
Its plasticising action can also help mortar adhere to masonry units more effectively, supporting a cleaner and more consistent finish across the completed work.
Reduces the need for lime
SikaMix Mortar Plasticiser is formulated to reduce the need to add lime to many general-purpose mortar mixes. This simplifies preparation and helps produce more consistent batches when the product is measured and used correctly.
Reducing the number of separate components required in a mortar mix can make site work more convenient, especially when preparing multiple batches throughout the day. It also reduces the handling and storage associated with additional bags of lime.
The product should only be used as directed and is not intended to replace lime in every specialist or traditionally specified mortar. Always follow the project specification and seek professional advice when working on heritage buildings, older properties or structures that require a particular mortar composition.
Suitable for a variety of masonry projects
This mortar plasticiser is suitable for many common building and maintenance applications, including:
- Bricklaying
- Concrete blockwork
- General masonry work
- Pointing and repointing
- Cement rendering
- Repairs using suitable cement mortar
Whether constructing a garden wall, completing an extension, laying concrete blocks or carrying out general repair work, SikaMix Mortar Plasticiser helps create a mortar that is easier to handle and finish.
Helps produce consistent mortar
Consistency is particularly important when preparing several batches of mortar for the same project. Variations in water or additive quantities can affect the behaviour and finished appearance of the mix.
Using SikaMix Mortar Plasticiser according to the stated dosage helps improve batch-to-batch consistency. Its liquid formulation makes it straightforward to measure and incorporate into the mixing water.
The correct quantity must always be used. Overdosing can introduce too much air, reduce mortar strength and affect its overall performance. Do not add extra plasticiser simply to make a stiff mixture more fluid. Instead, check that all components have been measured accurately and that the specified mix design is being followed.
Application guidance
Shake or agitate the container before use if instructed on the packaging. Measure the required quantity carefully and add it to the mixing water rather than pouring it directly onto dry cement.
Place the required sand and cement into a clean mixer and begin mixing. Gradually add the prepared water and plasticiser solution until the mortar reaches the required consistency. Avoid adding excessive water, as this can weaken the finished mortar and increase the risk of shrinkage, cracking or staining.
Continue mixing until the mortar has an even colour and uniform texture. Use the prepared material within its normal workable period and do not attempt to revive mortar that has started to set by adding more water or plasticiser.
Dosage requirements can vary depending on the application, mix proportions and site conditions. Always consult the latest Sika product information and follow the instructions printed on the container.
Storage and safe handling
Store SikaMix Mortar Plasticiser in its original, securely closed container in a dry location. Protect it from frost, extreme temperatures and direct sunlight. Keep it away from children and animals.
Suitable protective gloves and eye protection should be worn when mixing and handling cement-based products. Fresh mortar is alkaline and can cause burns or irritation after prolonged contact with skin. Wash off any splashes promptly and follow the safety guidance supplied with both the plasticiser and the other components of the mortar mix.
