Description
POLYMER MORTAR is a general purpose non-shrink, cementitious, trowel applied single pack repair mortar for repairs to Concrete sections and Plastered surfaces.
POLYMER MORTAR is composed of good quality cement, properly selected aggregates & additives. It is used & designed for repairing of damaged reinforced concrete elements like columns, beams & structure
Areas of Application
Any General Concrete Repairs areas such as –
Ceiling surfaces, Wall plaster, facade, etc.
Concrete substrates
Patch and Repair Mortars: Grouts for repairing cracks and de-lamination of concrete structures such as sidewalks, driveways, and walls. New mortar will not stick well to old concrete without polymer modification.
Features & Benefits
Ready to use Cement based Polymer mortar – No need to add sand, cement & aggregates, so saves time & energy
Needs to be mixed with water only – No additional dispersion liquid is necessary
High bonding strength –Suitable for overhead surfaces & can also be sprayed
Multi-purpose – Can be applied on horizontal, vertical and overhead surfaces without any form work and can be used along with plastic or steel fibers
Low permeability – Offers extremely low permeability to water carbon dioxide and chlorides
Improved workability. Polymer modification noticeably improves application characteristics, making the mortar more fluid and easier to handle and apply.
Improved strength and durability. Cured polymer-modified mortars generally have improved tensile strength, flexural strength, impact and abrasion resistance, water resistance, and chemical resistance versus unmodified mortars
