For Engineers

LRM ™ mortar as a repair layer for concrete surfaces that have been destroyed or honeycombing gives a uniform look to the desired surface. This mortar has been noticed by supervisors and designers to eliminate cracks, honeycombed, roughness of concrete surfaces in exposed concrete facades, which need to maintain the shape of the concrete, and also due to its cost-effectiveness.

For Contractors

This product, which is a type of modified polymer, only needs clean and potable water to prepare the mortar, which is easy to mix and implement. There is a very strong connection between the bonds of this mortar, which can be called a cosmetic repair mortar for smoothing the concrete surface. This mortar is used for the facade of the building or places where beauty is considered to fill the voids and seams of prefabricated concrete walls. Also, LRM™ mortar can be applied to underlay all kinds of epoxy and polyurethane paints.

Application Instructions

How to prepare

Before preparing the mortar with the required thickness, you should wet a thin layer that is in direct contact with the LRM™ mortar. When this product is used to fill the cavity, the material is spread directly in the pores with a hemp cloth and a trowel. The concrete surface must be completely clean and free of oil and grease, without water and additional substances, dust, and Damaged concrete must be removed. Moisten the desired surface for high adhesion.

Mixing procedure

Pour the dry ingredients gradually and little by little into a container and mix with a certain amount of clean water or mix with a mixer at low speed until a homogeneous and uniform gray mortar is obtained.

Clearing the surface

Tools and mixers should be cleaned with water immediately after use. It will be possible to clean the dried and left materials only by mechanical methods or special brushes.

Guide to Quality Control (QC)

• Using a mask due to the creation of suspended particles in the air
• Use gloves to prevent skin allergies
• Use safety glasses to prevent eye irritation
• Use of clothes/gloves and safety glasses in environments exposed to chemicals
• The environment should be well ventilated
• In case of skin contact, wash with soap and water
• Contact with eyes should be washed immediately with plenty of water
• In case of breathing problems during use, visit a doctor.


It can be used up to 12 months after production in unopened special packages, in case of storage, the packages should be kept at ambient temperature, in a dry place and away from direct sunlight and moisture.
