BONDEX-421 is a water based epoxy primer designed to deliver exceptional adhesion even on the most demanding surfaces, providing a strong bond to low porosity substrates such as ceramic tiles, quarry tiles, timber and concrete. With its rapid curing, low odour and easy application, it is a highly versatile solution, suitable both as a specialist bonding primer for difficult conditions and as a general purpose primer. In some situations, two coats may be required to ensure complete sealing and a smooth, uniform finish, always offering a durable and reliable base for the highest standards of protection and coating performance.
