Consult Technical Team for further information.

Surface Preparation

Blastrack/scabble all surfaces to remove any laitance or contaminated surface layers to expose fresh, sound and firm concrete.

The underlying concrete core should be tightly bound and dry, remaining surface dust should be removed by brushing or further vacuum cleaning. Fibre filled concrete must be treated specially, please consult Sherwin-Williams.

The moisture content should be checked in at least two places within each section of concrete. 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. Any areas of floor which are pitted, very rough, or have any large blow holes, should be smoothed off using a 5:1 by weight blend of P515:M689 prior to application of the Epidek M689 Primer. It is recommended that prior to application of Epidek M689 systems contact is made with Sherwin-Williams.

Due to the varying nature of concrete substrates, it is to be advised that a small trial area is prepared of the Epidek M689 system prior to coating the entire floor area.

Application Conditions & Overcoating

The material must be applied at temperatures in excess of 10°C. the substrate and ambient air temperature must be in excess of 10°C and the relative humidity should be no more than 85%. Substrate temperature should be at least 3°C above the dew point and always above 0°C.

Application below 10°C is not recommended.

Development of satisfactory physical properties including hardness and abrasion resistance will be obtained within 24-48 hours at a temperature of 10°C. In order to achieve optimum water and chemical resistance, curing temperature needs to be maintained above 10°C during curing.

If it is desired to overcoat outside the times stated on the data sheet, please seek advice from our Technical Team.
