All surfaces must be thoroughly dry before applying Fortis Coat 519. It is best applied with a 5mm good quality roller. It is best to pour directly out of the can/pail provided onto the floor and work your way across the room. If you must work out of a tray or working pot decant sufficient for immediate use. Seal original container to prevent moisture exposure. Decant only the amount that is sufficient for 30 minutes use and do not return unused product to original container. Sand lightly between coats to remove defects using 150 grit mesh screen.


Substrates should be thoroughly sanded or ground to provide a keyed surface. If applying over existing coatings adhesion should be tested. Remove all potential contaminants.
