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!

  • 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.
  • 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.
  • ARDEX SX™ Traffic Recommendations
    We are writing to clarify suitable traffic conditions for areas where ARDEX SX™ 100% Silicone Sealant for Tile and Stone Applications is used. ARDEX SX is suitable to receive pedestrian traffic in residential and light commercial applications. Please note that ARDEX SX is not recommended for floor installations in heavy commercial applications, such as airports and shopping malls. However, ARDEX SX is suitable for use in non-traffic areas and on walls in heavy commercial applications.
  • Recommendation Clarifications for Glass Tile Installations
    We are writing to clarify our recommendations for installing glass tiles. Please see the following chart; “X” denotes an approved application:
  • ARDEX UI 720™ FLEXBONE® Recommendation
    We are writing to clarify our recommendations for installing ARDEX UI 720 FLEXBONE over adhesive residue. If the adhesive residue is tacky, spread a polyethylene cleavage membrane or slip sheet (min. 4 mil thickness) over top prior to installing ARDEX UI 720 FLEXBONE. This will prevent the floating membrane from sticking to the adhesive.
  • 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.
  • Pre-Leveling with ARDEX ECRS Mortars
    We are writing to clarify our recommendations for using ARDEX TRM, ARDEX FDM, ARDEX FDX or ARDEX FP (hereafter referred to as “ECRS mortar”) beneath ARDEX underlayments, toppings, dressings or sealers.
  • ARDEX BACA Recommendation
    We are writing to clarify our recommendations for installing ARDEX BACA. For all applications, ARDEX BACA must be allowed to dry to the touch prior to placement of the repair mortar or concrete. The mortar or concrete must then be placed within 24 hours.
  • ARDEX ARDIFIX™ Packaging and Recommendation
    Packaging: ARDEX ARDIFIX will now be available as a 2 gallon unit that contains 1 gallon each of parts A and B. This size will be offered in addition to the 22 oz. dual-cartridge dispenser. Mixing and Application: The 2 gallon unit has its own mixing and application instructions.
  • APCS Installation Environments
    We are writing to clarify suitable installation environments for APCS applications. APCS applications are used with great success in interior, dry environments that receive foot traffic and/or minimal rubber-wheeled traffic, such as retail shops, showrooms, residences and office lobbies.
