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™ 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.
- Grade Levels for LU 100 GS-4 and K 22 F
There are three grade levels that we come across on any given job site: below grade, on grade and above grade. While most of our products are suitable for installation on all grade levels, ARDEX GS-4, ARDEX LU 100 and ARDEX K 22 F are limited to “above-grade” applications only where the space below is properly controlled for temperature and humidity. While this may seem straight forward, there are some special circumstances when determining where these products can be used. By definition, an on-grade substrate is one that has direct contact with the ground and sits on the surface of the earth. A below-grade substrate is also in direct contact with the ground, but is below the surface of the earth. Finally, an above-grade substrate is classified as being above the earth’s surface with no ground contact.
- 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.
- 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 Underlayments and RH Readings Above 90
It has come to our attention that floor covering and adhesive manufacturers are approving their materials for installation over concrete with relative humidity levels up to 100%. While we historically have deferred to the flooring manufacturer to determine whether moisture mitigation is needed prior to installing an ARDEX underlayment, there now are exceptions to that policy. We first confirmed this via a technical update in June 2012, attached below for your reference. As an addendum to Update 12, we are asking you to contact the Technical Department if ARDEX underlayments or toppings are being considered for installation over concrete in conjunction with any adhesive or floor covering that is approved for installation at relative humidity levels above 90%. This not only will help us ensure your success by providing a sound recommendation but also will help us stay informed on this emerging market trend. We appreciate your help with this.
