Zusammenfassung:The present invention relates to mortars which include a blend of cellulose ether compounds and exhibit improved pot life, water retention capability, and open time, as well as high tensile strength values. These mortars can be used in the fabrication of external insulation finishing systems (EIFS), particularly in hot environments. The cellulose ether blend includes hydroxyethylcellulose ether and methylhydroxyethylcellulose ether. Water soluble anionic polyacrylamide and hydroxypropyl starch can also be added to the mortar.
