Our Technical Services department monitors 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.
- 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.
- 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.
- Warm Weather Installation Guidelines
We are writing to clarify our recommendations for the installation of ARDEX and W.W. Henry materials (to include patching, leveling, tiling and ARDEX Engineered Concrete Repair Systems materials) during periods of warmer weather. In accordance with the Portland Cement Association, “…if the temperature… will exceed 77°F, a plan should be developed to negate the effects of high temperature.” There are four temperatures that need to be checked: air, substrate, material and water. Knowing these temperatures and employing the installation guidelines described below will help ensure the desired results are achieved.
- APCS Cleaning and Maintenance Procedures
We are writing to share our recommended cleaning and maintenance procedures for the ARDEX Polished Concrete System (APCS) products. These procedures are detailed below.
- 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.
- 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.
