The dry primer layer thickness of the Briosil primer 6/7360P should be 70 μm for ideal protection. In case you prefer spray application, then apply two thin layers of 35 μm.
The recommended dry layer thickness of our Therm-O-signal topcoats is 40-50 μm. In case you prefer spray application, then apply two thin layers of 20-25 μm. It is not recommended, to apply one thick layer of 40-50 μm by spray, as it involves a high risk of sagging.
Please note that excessive use of our primer and topcoat will result in boiling points during the curing process.
