The underlying concrete core should be tightly bound and dry, remaining surface dust should be removed by brushing or further vacuum cleaning.

The sections will normally be separated by a waterproof membrane. The maximum level acceptable is 7% for the application of M689 Sealercoat. Where previous coatings have been applied, these must be completely removed prior to application of the M689 based systems.
