Many people are opting for liquid screed floors due to their ease to lay and the final results of beautiful smooth floors. However, there are certain processes when laying them which some people think they are able to skip. One of these key processes you need to do is moisture testing. Think you can just make do and ignore this crucial test? Keep reading to find out why we think you should not.
What Does the Moisture Test Do?
A screed moisture test tests that the floor is sufficiently dried out. Moisture testing is incredibly important as it will let you know whether or not you can lay your further flooring coverings. You need to find out whether or not a floor is set as there can be serious issues if you try to proceed with the build without proper screed testing.
Depending on the project, it could take over 100 days for the screed to fully dry. When these sort of time frames are being used, every stage needs to be signed off upon completion as anything which goes wrong can delay things even longer.
Laying the floor prematurely can result in a poor quality of the floor overall and this often isn’t acceptable. If you are looking for high-quality floors, you need to give them time to dry out and moisture testing is the best way to ensure that this happens. Let’s take a closer look at some of the tests you can do.
This method is not used very often anymore as it can take some time to implement and get the necessary readings but it can still be accurate. A calibrated hygrometer is placed onto the screed in a sealed environment for 72 hours. It measures the moisture released by the screed in this time by measuring the humidity of the sealed area.
Concrete Moisture Test
This method is much speedier and is used to yield accurate results in a short amount of time; perfect if you are constrained by deadlines. All you need to do is lay a calibrated Tramex meter against the screed to get the moisture content.
A dry screed is one which registers anything below a moisture content of 0.5%. Even once this reading has been obtained, the room should be kept at a controlled temperature of 20°C with a humidity rating of approximately 50%. This should ensure that the floor will maintain the correct quality needed for the final floor finish.
Testing your floors might seem like an unnecessary step, especially if your build is behind schedule, but it has more benefits in the long run. It will cause you more problems trying to fix a floor that was not laid correctly as opposed to just taking the time needed to perform the necessary tests. No matter how dry you think your floor is, just perform a quick screed test to make certain. Your floor might appear to be dry even if it isn’t, so just do the test quickly to find out and save you trouble later on.
