Thorough substrate preparation is essential.
All contact surfaces must be sound, clean and provide good mechanical key. Remove all loose material, plaster, paint and oily deposits.
Roughen smooth concrete by scabbling or other mechanical means.
Corroded reinforcing steel should be fully exposed and cleaned back to bright metal. Cleaned steel should be protected by Steel Primer.

The substrate should be surface dry before application of Cretex LM Primer.
Ensure Cretex LM is applied as soon as the LM Primer has become tacky and before the priming coat has dried.

Stir well before use.
Apply the Cretex LM Primer using a stiff bristle brush, working well into the surface.
