## Summary description

Liquid plasticizer for floor heating systems, mc expert model MC-500-0450 in a 5 L container. Designed to modify properties of floor heating compounds and screeds, improving workability and flexibility, reducing cracking risk. Suitable for use with cement and anhydrite screeds in underfloor heating installations to enhance application and durability.

## Long description

mc expert MC-500-0450 Floor Heating Plasticizer is a liquid admixture supplied in a 5 L container, formulated to improve the properties of floor heating screeds and compounds. It is intended for use with cement and anhydrite-based screeds in underfloor heating systems to increase workability, improve cohesion, and reduce the risk of shrinkage cracks during curing. The product helps achieve a more uniform application and can contribute to a durable wearing layer when correctly dosed and mixed.
Advantages
The plasticizer enhances flowability and workability of screed mixtures without compromising strength when used according to manufacturer recommendations. It improves adhesion within the mix, reduces water demand, and lowers the likelihood of surface cracking caused by shrinkage. Its liquid form allows for homogeneous dispersion in mixing water, supporting consistent screed placement over underfloor heating installations.
Suitable for
Preparation of cement-based floor screeds for underfloor heating systems
Preparation of anhydrite (calcium sulphate) screeds used in heated floors
Mixes where improved flowability and reduced water content are required
Installation scenarios seeking reduced shrinkage and improved surface integrity
When it may not be suitable
This plasticizer is formulated for cement and anhydrite screeds and may not be suitable for mixes that require specialized additives such as air-entraining agents, retarding admixtures, or polymer emulsions unless compatibility is confirmed. It should not be used as a standalone sealing, bonding, or waterproofing product.
Key specifications
Form: liquid
Volume: 5 litres
Intended use: plasticizing admixture for floor screeds in underfloor heating systems
Compatible screed types: cement and anhydrite (calcium sulphate) screeds
Main effects: improved workability, reduced water demand, decreased shrinkage cracking
How to use
Add the plasticizer to the mixing water or directly into the mix according to the dosing instructions provided by the manufacturer or technical datasheet. Mix thoroughly until a homogeneous consistency is achieved, ensuring even distribution of the admixture throughout the screed. Follow recommended water-to-material ratios for the specific screed product and avoid overdosing. Place and compact the screed over the underfloor heating elements, then cure following standard procedures for the chosen screed type and ambient conditions.
What to consider before purchase
Confirm compatibility with the selected screed material (cement or anhydrite) and any other admixtures you plan to use
Check recommended dosage and prepare correct mixing equipment for uniform dispersion
Ensure storage conditions: frost-free, closed container away from direct sunlight
Verify required coverage per m2 and the volume needed for your project
Usage recommendations
Use the product according to the technical datasheet and local building standards. Measure doses precisely, mix thoroughly, and allow proper curing time for the screed before switching on underfloor heating. Conduct a small trial mix if using the plasticizer with unfamiliar screed formulations or additional admixtures to confirm workability and strength outcomes.
