What types of resin mortars are covered under this code?

The code covers Furan, Phenolic, Epoxy, and Polyester resin mortars.

Which Indian Standard provides the testing methods for these mortars?

The testing methods are detailed in IS 4456 (Parts 1 and 2).

IS 4832

: 2000

Chemical Resistant Mortars, Part II: Resin type

CurrentSpecializedSpecificationMaterials Science · Flooring, Wall Finishing and Roofing

This standard prescribes the requirements for resin-based chemical resistant mortars (furan, phenolic, epoxy, and polyester types) used for bonding chemical resistant masonry units. It specifies essential physical properties, chemical resistance, and storage requirements for ensuring durability in highly corrosive industrial environments.

Practical Notes

The pot life and curing time of resin mortars are highly sensitive to ambient temperature. Mix only quantities that can be applied within the working time.

Ensure strict adherence to the manufacturer's recommended ratio of resin, hardener, and filler to avoid poor curing and compromised chemical resistance.

Substrate preparation is critical; ensure surfaces are dry, clean, and primed (if required) before application.
