R-50 Latex Mortar Overlayment

Product Data Sheet

DESCRIPTION

Raeco R-50 is a two component, concrete repair and topping

compound consisting of a uniform,premixed blend of portland

cementsandgradedwashedsilicaaggregateswithaliquidlatex

modiﬁer to promote lasting surface adhesion, for renovation

and new construction. R-50 can be applied from feathered

edge to any depth, for thickness greater than 1/2” (12.7 mm)

use appropriate aggregate. R-50 should be used for horizontal

surfaces.Suitable for interior and exterior use,a sealer or coating

is recommended when used for a wearing surface.R-50 provides

excellent freeze-thaw resistance against the penetration of

deicing salts and other contaminants. Raeco R-50 contains no

gypsum, chlorides, ferrous metals or corrosive agents.

SURFACE PREPARATION

Surfaces to be covered must be structurally sound, clean and free of dust, oil, grease, sealers, curing compounds,

laitance, release agents or other surface contaminants. For smooth surfaces, we recommend mechanical abrasion to achieve an ac-

ceptable surface proﬁle. The cleaning and preparation method selected depends on both the sub-ﬂoor material and its condition.

Acid etching is not recommended. For optimum adhesion, mix R-50 with the latex to a slurry consistency and brush thoroughly into

the area to be covered. Raeco R-2000 may also be used as a bonding medium. DO NOT USE R-50 LATEX AS A BONDING AGENT.
