Any moisture condensation or observable darkening of the color of the concrete underneath the sheet suggests excessive moisture and astm d the slab is not ready for d42633 moisture-sensitive floor covering.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. However, the reverse is not true. Another plus asfm that the test provides hard numbers expressed as astm d RH that make it very easy for astm d when the slab is dry enough for installing the finished floor. A concrete floor slab with excess moisture pretty much guarantees a flooring failure due to serious problems such as discoloration, bubbles, curling, adhesive deterioration, cupping, buckling, warping, mildew or mold.
Method for Indicating Moisture in. If the document is revised or amended, you will be notified by email. For a relatively minor investment in testing equipment, contractors and flooring installers can save s4263 time and money. Subscription pricing is determined by: Concrete by the Plastic Sheet.

Standards Subsctiption may be the perfect solution. Its approach has been scientifically proven to provide a true picture of the overall moisture condition of the slab.
No serious flooring failures due to hidden, excessive moisture in the slab. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
No serious flooring failures due to hidden, excessive moisture in the slab. A positive result with observable moisture underneath the plastic sheet confirms that the concrete slab is too wet for a flooring installation.

The test method involves taping an inch mm square of polyethylene film onto a concrete slab and waiting at least 16 hours.
Observable moisture on the underside of the plastic sheet depends on astm d dew point, which in turn depends on the surface temperature of the concrete. Afterward, the underside of the sheet is examined for signs of moisture. Yes, it matters a great deal. You may delete a document from your Alert Profile at any time.
