Dry time is the recommended length of time between coats of product, often called recoat time, and cure time is the length of time recommended before subjecting your finished project to daily use. The following factors can influence your dry time:
TEMPERATURE AND HUMIDITY
All of General Finishes products' dry and cure time recommendations are subject to the conditions of the room in which you are refinishing and storing your piece. Ideal conditions are 70°F/21°C and 50% humidity. Cooler temperatures and high humidity levels can prolong dry time any from 8-10 hours.
APPLYING OIL AND WATER-BASED PRODUCTS TO THE SAME PROJECT
When applying an oil-based product over a water-based product and vice versa, dry time increases. It's extremely important to be sure your first application of finish has completely dried before applying the next layer. When switching from an oil-based product to a water-based product, wait 72 hours to apply your next coat of product. When switching from a water-based product to an oil-based product, wait 24 hours.
YOUR STARTING SURFACE
Applying product to a raw wood surface will result in a shorter dry time. When applying over an existing finish, dry time increases.
METHOD OF APPLICATION
Painting your finish on will require a longer dry time. If you are applying and then wiping off, or spraying, dry time is less.
Before adding additional coats of product, the following DRY times should be honored:
The following are average CURE times based on recommended temperature and humidity:
- 21 days for water-based products
- 30 days for oil-based products
- You can use a piece lightly after about 7 days but be cautious - the finish will still be curing for another 2 or 3 weeks.
Some of General Finishes wait times might seem a bit generous but we need to account for all variables beyond our control. You can test your surface for dryness ahead of schedule by knowing what to look for. There are two ways to tell if it is an oil-based product is dry. If it is no longer tacky and it doesn't smell, it is dry. You can tell if a water-based product is dry by touching it. If its cool to the touch, it's not dry. If you can sand a water-based topcoat to a powder, its dry.
