This code lays down recommendations for the storage, mixing, application, and curing of resin-type chemical-resistant mortars used for bonding acid-resistant bricks and tiles. It covers phenolic, furan, epoxy, and polyester resin mortars primarily used in aggressive industrial and chemical environments.
Code of practice for the use of resin-type chemical-resistant mortars
Quick Reference Values
Typical mortar joint thickness3 mm to 6 mm
Minimum curing time before chemical exposure7 days at 27°C
Pot life at ambient temperature20 to 40 minutes
Practical Notes
Resin mortars are highly sensitive to temperature; high temperatures drastically reduce pot life, while low temperatures delay curing.
Ensure the substrate is completely dry and free from dust, oil, and grease before application to achieve the required bond strength.
Mix only the amount of mortar that can be consumed within its pot life to avoid material wastage and premature hardening in the mixing vessel.
