(K51-1)  
Description  
KemikoRepels (K51-1) is a 0-VOC, extremely user-friendly, waterborne silane/siloxane emulsion  
for sealing KemikoStone Tone Stained concrete and other cementitious substrates. KemikoRepels  
Sealer is a water viscosity, single component product that is formulated to repel water, reduce  
efflorescence and frost damage, allows substrate to breathe, has very little or no odor, does not  
contain solvents, and preserves stained concrete color and natural gloss. KemikoRepels Sealer is  
resistant to UV and high alkalinity exposure.  
Applications  
KemikoRepels K51-1 is applied to properly prepared stained and bare concrete, new and existing  
stucco finishes, fired clay brick, and many other cementitious mortars. Typical applications include  
commercial and residential driveways, walkways, facades, pool decks, stamped and stained  
concrete, new architectural poured in place and precast concrete, and many other horizontal  
and vertical above grade exterior surfaces requiring additional protection. Excellent replacement  
product for high VOC solvent base water repellents and sealers with excellent wetting properties.  
Not formulated to be applied over previously sealed substrate, non-porous substrate, KemikoDyes or  
Rembrandt™ Polymer Stain.
