Customer Questions & Answers
Q : What percentage does concrete have to be to be able to paint? My meter is reading OL?
A : This may vary according to the product you are applying to it (for example some primers are specifically designed for damp concrete) but unfortunately a reading of OL makes it impossible to ascertain exactly how damp the wall is as it is outside the measurement range
Q : The meter is saying ol in brick concrete mode does this mean there is damp in wall.
A : Hi Ian, the manual is a bit ambiguous as it says a reading of OL means "Out of range for this meter" - so whether this means the reading is outside its scope of measurement, or it can't read anything at all, I wouldn't like to say (although it looks like we were previously advised the former) - I would advise calling Draper's customer service department if possible? on 02380494344
Q : What does the reading OL signify?
A : I can confirm that if you are receiving a reading of OL, then the reading is over the limits that the detector can detect. (Over 40% moisture reading in wood and over 2.0% in material)
