Recommended thickness and forecasted consumption
Recommended thickness for a long-lasting protection is 3 mm. Since application is carried out by hands, it is hard to obtain a homogeneous thickness: usually an average thickness of 5 mm is recommended so that in no spots thickness will be lower than 3 mm. Theoretical consumption is stated in each technical sheet. Said quantity increased by a 10% for possible wastage grants a min. thickness of 3 mm.
Underwater: touch dry in 10-12 hrs/ complete curing in 7-10 days.
In the air: touch dry 4-6 hrs / complete curing in 7 days approx. at 2S°C.
How to check the dry film thickness of the applied coating
To check the dry film thickness of the applied coating use a magnetic thickness gauge such as Microtest. For the coating applied underwater check the dry film thickness as follows: engrave the coating in order to have a square pattern of 3cm x 3cm. Remove the small block and check the thickness with a gauge. Seal uncovered steel with ZAMSUB FOR SPREADING.
