  • ARDEX 8+9™ and ASTM E514
    We are pleased to announce that ARDEX 8+9™ Rapid Waterproofing and Crack Isolation Compound has passed ASTM E514 Standard Test Method for Water Penetration and Leakage Through Masonry. During a 4-hour testing cycle, ARDEX 8+9 was exposed to 40 gallons of water per hour and 10 lb. of air pressure per square foot. Testing showed that ARDEX 8+9 provides total installation protection from water penetration and reduces the risk of condensation development in the building envelope.
  • High Rolling and High Point Loads Vinyl Flooring
    It has come to our attention that there is confusion in the market over when it is necessary to upgrade to a high-performance, high-solids, two-component epoxy adhesive for the vinyl flooring installations. First, it should be noted that, in general, resilient flooring manufacturers test in accordance with ASTM 970 – Standard Test Method for Static Load Limit, which measures a vinyl’s ability to withstand and recover from indentations introduced into the material through the application of a static point load. The Resilient Floor Covering Institute (RFCI), commenting on this testing methodology, has warned that the criteria for static loading as specified by ASTM 970 may be insufficient, particularly in regards to the ASTM 970’s deficiency in addressing dynamic loads. Citing RFCI’s definition of a dynamic load, “Dynamic loads are created when a load is placed on the floor, and then moved around the floor's surface by a rolling, sliding or dragging motion.” Based on this definition, loads such as these are common within the daily operation of a hospital or medical care facility. While vinyl flooring often is able to withstand static loads in accordance with ASTM 970, it may fail when those same loads become dynamic. The selection of the proper adhesive can help to mitigate the risk of static and dynamic loads from permanently deforming the vinyl flooring.
  • 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 Cleaning and Maintenance Guidelines
    By routinely cleaning your floor properly, you will maximize its performance, appearance, and slip resistance. If you have a floor cleaning service, make sure they are instructed according to this guide.

    We are writing to clarify our recommendations for installing glass tiles. Please see the following chart; “X” denotes an approved application:
  • 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 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.
  • Recommendations for Resin-Backed Tiles
    We are writing to clarify our recommendations for the installation of resin-backed tiles using ARDEX tile mortars. There are two options for this application: 1) onsite testing can be completed, or 2) a recommendation can be provided by the ARDEX Technical Service Department once the tile in question has been tested.
  • 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 K 60™ ARDITEX Over Wood Substrates
    In response to market feedback, and subsequent to extensive in-house and field testing, we are pleased to announce that ARDEX K 60 can now be installed over properly prepared wood substrates. The wood subfloor must be a minimum of 3/4” tongue-and-groove, APA-rated Type 1, exterior exposure plywood, or an approved OSB equivalent, must be constructed according to prevailing building codes and must be clean, sound, solid and securely fixed to provide a rigid base free of undue flex. For details regarding substrate preparation, please see the installation recommendation linked below.
