Additive for mortar replacing lime mc expert MC-500-0210 1 L

Additive for mortar replacing lime mc expert MC-500-0210 1 L is a liquid admixture formulated to substitute lime in masonry and plaster mortars. Supplied in a 1 L container, the product changes mortar rheology and setting behaviour to improve workability, adhesion and ease of application. It is intended for use in bricklaying, rendering and repair mortars where traditional lime is replaced or reduced.

Advantages

This liquid lime-replacing additive improves mortar plasticity and cohesion, making mixing and trowelling easier. It promotes more uniform application and can reduce cracking risk by enhancing mortar flexibility. The formulation is compatible with common cement and sand mixes used in masonry and plastering, and its concentrated 1 L unit provides a measured dosage for small to medium jobs.

Suitable for

• Masonry mortar for brick, block and stone work
• Plaster and render mortars on walls and ceilings
• Repair mortars for patching and refurbishment
• Situations where lime use is restricted or substitution is preferred

When it may not be suitable

This additive is not a direct structural binder and does not replace cement; it is intended to modify properties of cement–sand mortars by substituting lime. It may not be suitable for high-strength or specialty mortars that require specific hydraulic lime performance or where manufacturer specifications mandate traditional lime content. Compatibility with very fine or unusual aggregate mixes should be tested before large-scale use.

Key specifications

• Form: Liquid additive, 1 L volume
• Intended function: Lime replacement in masonry and plaster mortars
• Effect on mortar: Improves workability, cohesion and flexibility; modifies setting characteristics
• Typical applications: Bricklaying, rendering, repair and refurbishment mortars
• Packaging: Compact 1 L container suitable for small to medium jobs

How to use

Add the product to the mixing water or introduce it during the mixing process according to the required dosage for the mortar type. Mix thoroughly until a homogeneous consistency is obtained and confirm workability matches the application method (trowel, float or pointing). Apply the mortar within its open time and protect fresh work from rapid drying or freezing until initial set. For best results, perform a small trial batch to verify dosage and final properties before proceeding to the full work scope.

What to consider before purchase

• Confirm compatibility with the cement and sand mix you plan to use
• Determine required dosage by performing a trial mix to achieve the desired workability and set time
• Check whether project specifications require traditional lime or a specific hydraulic lime product
• Plan storage and handling: keep sealed and frost-free to preserve performance

Usage recommendations

Use the additive in measured doses and verify performance on a trial panel. Always follow standard masonry and plastering practices: control substrate moisture, avoid application in extreme temperatures, and cure new work appropriately to achieve consistent results.
