| Résumé : |
There are many ways moisture can affect concrete floor coatings but moisture testing alone is not sufficient to detect all potential problems. 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 concrete |
