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
