Time Between Coats
Definition - What does Time Between Coats mean?
Time between coats is the time required for the application of the second coating after the first coating has been applied. This period can last from minutes to hours, depending on the type of paint or coating used.
Observing the recommended time between coats ensures proper application of coating. Not observing proper intervals between coats makes the painted surface more prone to damage or the effects of corrosion such as flaking, peeling and rusting.
Corrosionpedia explains Time Between Coats
Time between coats should be observed when applying coatings to all surfaces, equipment and machinery. Improper application of paint related to the interval of coating application could result in peeling, which could result in coating failure.
In order to prevent this from occurring, the right type of paint and proper application should be implemented. For optimal results, at least two coats are required, preferably applied through a crisscross pattern to prevent thin spots. The initial coat must have the right coverage and should be dry according to standard measurements of wetness and dryness. To ensure enough coverage, a barometer may be used.
Adequate time between applications of coats should be allowed, which is about 20-30 minutes on average. Allowing time for drying is very important, as it makes the coating impermeable to rusting oxidation. Additionally, inadequate time between coatings decreases the paint's protection and takes longer to dry.
