Polymer-modified mortar Fischer 53105

Fischer 53105 is a ready-to-use polymer-modified mortar paste supplied in a 0.31 kg volume. Designed for maintenance and small-scale construction work, the mortar provides improved adhesion and flexibility compared to cement-only pastes. The formulation is intended for filling, bonding and repair tasks where a compact, easy-to-apply mortar is required.

Advantages

The polymer modification enhances bond strength to common substrates such as concrete, masonry and plaster. The ready-to-use consistency eliminates on-site mixing and reduces preparation time. Its flexible cured structure helps accommodate minor substrate movements and reduces the risk of cracking. The compact packaging suits small repair jobs and instances where precise quantities are needed.

Suitable for

• Small repairs to concrete and masonry
• Filling gaps and joints in plaster or render
• Bonding tiles, trims or fixtures where a paste mortar is required
• Maintenance work in indoor and sheltered outdoor areas

Key specifications

• Form: ready-to-use paste
• Modifier: polymer-enhanced formulation for improved adhesion and flexibility
• Net content: 0.31 kg per unit
• Color: mortar/grey (appearance may vary by batch)
• Application temperature: suitable for typical construction ambient conditions (check label for limits)

How to use

Apply the Fischer polymer-modified mortar paste to clean, sound and dust-free substrates. Remove loose material, oil and grease before application. For best results, press the paste into gaps or onto the repair area and shape or smooth with appropriate tools within the working time indicated on the product label. Allow the mortar to cure undisturbed until it reaches intended hardness. Curing time depends on layer thickness, substrate and ambient conditions.

Usage recommendations

Use personal protective equipment, such as gloves and eye protection, when handling the mortar. Store the product in a dry, frost-free place and avoid direct sunlight. For exterior exposed applications or load-bearing repairs, consult technical data or a specialist to confirm suitability; perform a small trial application if necessary to verify adhesion and curing under local conditions.
