Product Information
SCHÖNOX RR is a cement-based rapid-setting repair mortar suitable for use on all cement- and gypsum-based substrates. It is designed for rapid-drying patchment repairs in interior areas.
SCHÖNOX RR can be installed up to 2”. Users can layer thicknesses above 1/16” up to 3/8” without aggregates and up to 2” with aggregates.
This heavy-duty, fine-grained compound is extremely fast-drying, even in higher layer thicknesses. It produces a very smooth surface with high hardness and strength and low shrinkage.
SCHÖNOX RR is rated EMICODE® EC 1PLUS R for very low emissions. It is suitable for castor wheel loadings above 1/16“ according to DIN EN 12529.
SCHÖNOX RR is suitable for patching, filling, and leveling of:
- Concrete, cement substrates
- Gypsum substrates
- Old substrates, such as ceramic tiles
- Old water-resistant adhesive residues
- Wooden substrates
- Stair steps and wall breakouts
SCHÖNOX RR can also be used on underfloor heating systems.

* All values are approximate, are subject to local climatic fluctuations based upon conditions at 70°F with atmosphere of less than 65% relative humidity following the recommended mixing ratio. Do not install underlayment or topping before the substrate has dried thoroughly.
Usage
Mixing Ratio:
Mix each 25 kg / 55 lb. bag with 5.5 liters / 5.8 quarts of water.
*If SCHÖNOX RR is extended with dry, clean aggregate (aggregate is added last) at a layer thickness of 3/8”–2”, type and amount of aggregate used will affect product performance. As qualities of locally available aggregates vary, we recommend performing tests prior to use on a larger scale. Do not overwater!
Recommended Working Method:
- Using a clean mixing bucket, add SCHÖNOX RR to cold, clean water to form a homogeneous mixture. Mix thoroughly for approx. 3 minutes using a heavy-duty drill (min. 600 RPM) is recommended to obtain a lump-free mix.
- Apply, smooth, and shape the leveling compound using a stainless steel smoother or a smoothing trowel.
- Do not mix more material than can be applied within 15 minutes.
- Protect curing SCHÖNOX RR layers from high ambient temperatures, direct sunlight, and draughts.
- Clean tools in water immediately
