• What is Eisenwall and what makes it a "premium" grade plastering cement?

    Eisenwall premium plastering cement is a proprietary hydraulic cement blend used in exterior plastering applications where accelerated set times, higher strength, superior durability, enhanced impact resistance, and reduced cracking are desired.

  • When / Why should Eisenwall be used?

    Any time it is desirable to save time and money and achieve a high quality, durable, crack-resistant exterior plaster finish is an ideal time for the use of Eisenwall premium exterior plastering cement. Many contractors realize significant time savings on their construction schedule when using Eisenwall cement. Eisenwall is ideal for schools and other "high traffic" public institutions that require a highly durable and impact resistant exterior finish.

  • What special equipment/procedures are required for the application of Eisenwall?

    Eisenwall is applied in much the same way as traditional plastic cements or Portland and lime. However, Eisenwall has a shorter setting time and certain precautions need to be taken for optimum application.

  • Can Eisenwall be mixed with Portland-based plastic cement to enhance its properties?

    While the Rapid Set Cement used in the manufacture of Eisenwall is compatible with virtually all Portland based plastic cements, mixing Eisenwall with other plastering cements will decrease its performance and is not recommended.

  • Can Eisenwall be used for crack repair or window/door installation?

    Eisenwall is ideal for patching holes and cracks and repairing damaged plaster areas from installation and retrofit of new windows and doors. Remodeling contractors can achieve significant time savings when using Eisenwall.

  • Is Eisenwall a "waterproof" plastering material?

    The special chemistry of the Rapid Set Cement used in the manufacture of Eisenwall makes it highly water resistant. Eisenwall also has very low permeability and is highly resistant to sulfate attack, outperforming type-V Portland cements.

  • Do I need special training or approval to use Eisenwall?

    While Eisenwall is applied in much the same way as traditional plastic cements, minor training is desirable and applicators must be manufacturer approved.

  • Can Eisenwall be machine applied (sprayed)?

    Eisenwall can be applied by hand (trowel) and by machine. Eisenwall contains special additives that make it easily workable by hand and ideal for pumping and gun spraying.

  • What is the minimum/maximum placement thickness and associated coverage areas of Eisenwall?

    Eisenwall can be placed in thicknesses from 3/8 in. to 3/4 in.+ in one coat. When gun applied it is sometimes desirable to place one coat and "double back" to achieve the desired thickness as soon as the first coat has achieved sufficient rigidity. Approximate coverage area is 5 square yards at 7/8 in. thickness.

  • Is Eisenwall an approved plastering material?

    Eisenwall premium plastering cement is fully approved. Eisenwall conforms to UBC 25-1 and is approved by ICC ESR-2671. Eisenwall is also approved by the city of Los Angeles, one of the most stringent approvals available.

  • What is the working time of Eisenwall and can it be extended?

    Under normal conditions (70o F) the working time of Eisenwall is approximately 75 minutes. During warmer weather or when longer working time is needed the setting time of Eisenwall can be extended with the addition of Eisenwall Set Control, or by using cooled sand and water. Use of warm or hot sand and water can will decrease the working time of Eisenwall.

  • Should I add lime to Eisenwall?

    Under no circumstances should lime be added to Eisenwall. Lime significantly decreases the performance of Eisenwall and could cause adverse effects.

  • Are there any special requirements for sand or water?

    Sand should be clean and free from deleterious amounts of loam, clay, silt, soluble salts and organic matter. High quality washed plaster sand is required. Water should be clean and free from deleterious amounts of silt and dissolved salts.
