11. Report discrepancies immediately to Ivy Hill, as installation of products installed with visual defects, mixed production runs or
incorrect style will not be honored.
12. Ivy Hill cannot accept responsibility for any loss or damage that may result due to processing or working conditions and/or
workmanship outside our control.
13. Ivy Hill uses the highest quality materials and performs all ASTM testing through third party testing. We advise users to confirm the
suitability of this product by their own tests.
JOB-SITE TESTING
1. Before job-site testing, the building envelope must be sealed (walls, roofing, windows, doorways etc., installed).
2. The area to receive the LVT flooring should be maintained at a minimum of 65° F (18° C) and a maximum of 85° F (29.4° C) for 48 hours
before, during and for 48 hours after completion.
3. The installation area and materials to be installed shall be maintained at a minimum of 65°F (18.3°C) and a maximum of 85°F (29.4°C)
for 48 hours before, during and for 48 hours after completion of the installation.
i. Relative humidity level extremes should also be avoided. General recommended humidity control level is between 35–55%.
If a system other than the permanent HVAC source is utilized, it must provide proper control of both temperature and
humidity to recommended or specific levels for the appropriate time duration.
4. Test sites must be properly prepared and protected for the duration of testing to achieve valid results.
5. Surface flatness for all subfloors: The surface shall be flat to 3/16″ (3.9mm) in 10 ft. (3050 mm) and 1/32″ (0.8 mm) in 1 ft. (305 mm).
To check flatness, place a 10-ft. straight edge, string, laser level or use another suitable method on the surface, and measure the
gap.
6. Concrete subfloors:
i. Concrete subfloors must be finished, cured, and free of all sealers, coatings, finishes, dirt, film-forming curing compounds
or other substances that may prevent proper bonding of the flooring materials (ACI 302.1 and ASTM F710).
ii. Randomly check concrete subfloor for porosity using the drop water test. Place a 1″-diameter drop of water directly onto the
concrete subfloor. If the water droplet does not dissipate within 60 to 90 seconds, the subfloor is considered non-porous.
iii. Concrete subfloors must have a minimum compressive strength of 3000 psi. Concrete subfloors shall not consist of
lightweight concrete or gypsum
iv. Moisture testing: Perform either the preferred In-situ Relative Humidity (RH) Test (ASTM F2170) or the acceptable. Moisture
Vapor Emission Rate (MVER) Test (ASTM F1869). For acceptable moisture limits please refer to the specifications of the
adhesive of choice.
v. Alkalinity: You must test surface alkalinity (pH) as per ASTM F710.
7. Wood subfloors and underlayment panels shall have the moisture content tested using a suitable wood pin meter. Readings
between the wood subfloor and underlayment should be within 3% and have a maximum moisture content of 14% or less.
MOISTURE SUPPRESSANT SYSTEM
Concrete subfloors that exceed adhesive specifications will require a Moisture Suppressant System. Due to complexities
associated with moisture vapor transmission, emissions and movement of soluble salts (alkalinity) in concrete subfloors, Ivy
Hill does not offer, recommend or warranty a specific solution for excess moisture in concrete slabs. However, there are many
companies that offer solutions with warranties for excess moisture in concrete slabs.
Ivy Hill suggests that you reference the current ASTM F710, “Standard Practice for Preparing Concrete Floors to Receive Resilient
Flooring,″ and ASTM F3010, “Standard Practice for Two Component Resin Based Membrane Forming Moisture Mitigation Systems
for Use Under Resilient Flooring Systems.″ Contact one or more of the following or other moisture suppressant system suppliers
