Technical Updates:

Our Technical Services department monitor installation trends, to ensure that our recommendations are optimized for your success. It is sometimes required to adapt our existing recommendations. Current technical updates are listed below and can be searched by product, date or other search term.

Are you preparing for an ARDEX product installation? We recommend reviewing the technical data sheet and technical updates for each product prior to installation. Then, contact us to meet your local sales representative and obtain a job-specific recommendation for your project!

  • High Moisture Conditions and ARDEX Underlayments
    When considering the moisture content of a concrete slab and its resulting suitability to receive ARDEX underlayments without moisture mitigation, we currently defer to the manufacturers of the finishing materials (adhesives and floor coverings) being used. But now, with manufacturers offering resilient floor covering adhesives that are approved for installation at relative humidity levels above 80%, we are adjusting our position, as follows.
  • ARDEX K 60™ ARDITEX IMO Certification
    We are pleased to announce that ARDEX K 60™ ARDITEX has been tested by the UL and meets all Primary Deck Covering requirements of the U.S. Coast Guard and International Maritime Organization (IMO). ARDEX K 60 complies with all applicable requirements in the IMO International Code for Application of Fire Test Procedures (FTP Code) and has been approved for use in shipbuilding applications where the IMO’s performance standards are required. Testing shows that ARDEX K 60 does not contribute smoke, toxicity or significant heat or flame spread, and the product has been issued a Coast Guard approval and a Certificate Approval #164.106/56/0.
  • Cold Weather Precautions for ARDEX and HENRY
    With winter approaching, we are writing to clarify our recommendations for storage, transport and installation of ARDEX and HENRY products during the colder months. General Information: Ideal storage and installation temperatures are detailed in the technical data sheet for each product. Never install ARDEX or HENRY products at substrate or ambient temperatures below 50°F (10°C). Note that, the colder the substrate and ambient temperatures, the longer the drying and/or cure times will be. Ensure that products are dried and/or cured prior to proceeding with subsequent installations and/or opening to traffic. Facilitate drying by circulating the air above the surface; do not blow air directly on the surface.
  • ARDEX P 51™ Dry Time Clarification
    We are writing to clarify that the dry time for ARDEX P 51 will vary with jobsite conditions and could be as little as 30 minutes. As with any waterborne material, ARDEX P 51 drying times are affected by specific jobsite conditions. Higher temperatures, good air flow and low humidity will accelerate dry times. Conversely, drying times may be extended for projects where temperatures are low, air flow is poor and/or humidity is high.
  • Extending ARDEX ERM™ with Aggregate ARDEX ERM
    We are writing to confirm our recommendations for extending ARDEX ERM with aggregate. The ARDEX ERM technical brochure is currently in the process of being updated.
  • ARDEX Products and Dew Point
    Dew point is the temperature at which moisture in the air condenses and forms liquid water on surfaces. This temperature varies based on site conditions. Every space, whether exterior or interior, acclimated or not, has a dew point. In exterior as well as non-acclimated, interior spaces, the chances of being close to dew point are much greater. On the other hand, when an area is enclosed and acclimated (HVAC operating properly), it is not likely that dew point will be reached. For example, in a space with a temperature of 70°F and an ambient humidity of 50%, the dew point for the space is 50°F.
  • Shaw Ecoworx Broadloom Carpet HENRY 351 FastPro™
    The recommendation is as follows: For individual lifts of ARDEX ERM that will be thicker than 2”, including full-depth repairs, extend each bag of ARDEX ERM with 25 pounds of clean, uniformly graded, 1/4” to 3/8” pea gravel dampened to an SSD condition.
  • ARDEX Products and OSHA Silica Standard Housekeeping Guidelines
    We are writing to clarify our recommendations for the installation of ARDEX products with consideration to the new OSHA Standard on crystalline silica. For complete information on the new OSHA regulations, visit www.osha.gov/silica. The recommendations detailed below are the result of independent, third-party air quality monitoring tests and are in accordance with OSHA Silica Standard Housekeeping Guidelines. Affected technical data sheets will be revised accordingly.
  • ARDEX ARDIFIX™ Recommendation
    We are writing to clarify our recommendations for using ARDEX ARDIFIX to fill dormant cracks and dormant joints prior to the installation of flooring materials. Where an ARDEX underlayment and finish flooring will be installed, ARDEX ARDIFIX must be sand broadcasted to refusal while fresh. The sand broadcasted surface of the ARDEX ARDIFIX is required to create a bonding surface for the ARDEX underlayment.
  • ARDEX SD-M™ Substrates that can affect the Performance of the Finish Installation
    In both aesthetics and durability, ARDEX SD-M™ Designer Floor Finish™ has proven to be a strong performer for providing a skim coat finish for concrete and other recommended substrates. This includes solid, non-porous substrates when used with the appropriate primer, as well as ARDEX Toppings or Underlayments where the substrate below would allow the ARDEX SD-M to perform as expected. However, it has come to our attention that ARDEX SD-M is also being installed over ARDEX Underlayments where the substrate below does not allow for maximum performance of a thin layer topping. These problematic substrates include gypsum, wood and adhesive residues.
