Sometimes problems are not apparent or may not even exist until coatings have been applied. Performing a moisture survey — an inspection of a building and its environment prior to performing any tests — will provide a clearer picture of the potential problems moisture in both liquid and vapor form can pose.

- FIGURES : 1. This area has been properly prepped for the ASTM F1869 test. Images courtesy of the author unless otherwise noted - 2. ASTM F2170 test. The floor is prepped (blasted or ground) around the test area - 3. This section of floor has not been prepped which could restrict the emission of moisture from the concrete rendering false test results. That, and the fact that there is a close crack, makes this an unsuitable test area - 4. This floor is clean, but it has not been properly prepped. Tight surface laitance will restrict the emission of moisture rendering lower (false) test results - 5. Exterior conditions such as snow piled against a building create potential for future moisture problems - 6. Moisture is trapped under entrance mats - 7. Moisture can lift coatings systems at saw cuts - 8. A hand-troweled finish on a floor patch - 9. Moisture damage to vinyl composite tiles is evident by the appearance of curling edges - 10. Osmotic blistering can indicate moisture problems in underlying concreteEn ligne : http://www.paintsquare.com/archive/?fuseaction=view&articleid=5885 Format de la ressource électronique : Web Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=28399
