Product Description

Sherwin Williams Epidek M689 - Formerly Leighs is a 100% solids, two pack epoxy primer / floor sealer for concrete floors.

Best Uses

Sherwin Williams Epidek M689 is formulated for application to suitably prepared concrete substrates as a primer/sealer coat.


Blast track / scabble all surfaces to remove any laitence 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 our technical team.

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 Sealer coat.

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. Recommended application via roller or float.

Recommended topcoats: Macropoxy M630V2, Epidek M153, Macropoxy M262, Epidek M339, Epidek M377, Epidek M689 must be overcoated within 3 days at 23°C or 4 days @ 15°C.
