It is important to take the necessary precautions to ensure that the coating is applied correctly and that the warranty on the product is not voided. To do this, it is best to use a firm step when applying the coating and to stop frequently to measure the thickness of the wet film with a wet film gauge. When using Acu-Shield, for example, the thickness of the wet film should be a minimum of 20 thousandths of an inch wet for each layer, and each layer should cure for 24 to 48 hours.
