MasterEmaco N 303 - Single component polymer modified fairing coat cosmetic mortar for concrete surfaces

MasterEmaco N 303 is a single component acrylic polymer modified repair mortar for use as a "fairing coat" or cosmetic mortar. When mixed with water, as directed, a fine grey trowellable mortar results which can readily be applied to fill in pores, blowholes and blemishes on a concrete surface.

MasterEmaco N 303 can be used as a 'skim' coat prior to the application of protective coatings.

MasterEmaco N 303 is specially formulated to produce a shrinkage compensating mortar with no cracking when applied in a thin section. Adhesion to concrete and flexibility are excellent.
