KBS Rust Converter is dry to the touch in 10 minutes and ready to recoat or topcoat after 24 hours. Those figures are measured at 72 degrees F, 50 percent humidity, and 1.5 mil thickness. Cooler air, higher humidity, extra coats, or a heavy coat will all stretch them out.
You do not rinse it off. KBS Rust Converter is not a dwell-and-rinse product. Spray it on and leave it there permanently. The chemical reaction happens as it dries, turning the rust black, and the converted layer becomes part of the finished surface.
What Changes the Timing
- Temperature. Use the product when the can is between 50 and 90 degrees F. A can that has been sitting in a cold shop or truck should come up to room temperature before you spray.
- Coat thickness. Cure and recoat time is extended with excessively thick coats.
- Number of coats. Multiple coats also extend the recoat time.
Topcoating
Once the converted surface has cured for 24 hours it is ready for paint. KBS Rust Converter is compatible with most topcoats and acts as the primer itself, so no separate primer is required. If you would rather not paint it at all, see what color it turns once cured.
Frequently Asked Questions: Dry Time and Topcoating
You leave it on permanently. KBS Rust Converter is not rinsed off the way an acid-based rust treatment is. Spray it onto the rusted surface and the chemical reaction turns the rust black as the coating dries. It is dry to the touch in 10 minutes and fully ready to recoat or topcoat after 24 hours.
Yes, once it has cured for 24 hours. KBS Rust Converter is compatible with most topcoats and acts as the primer, so no separate primer is required. Do not paint over it before the 24 hour mark, even though it feels dry after 10 minutes.
Dry to the touch in 10 minutes, and dry to recoat or topcoat in 24 hours. Both figures are measured at 72 degrees F, 50 percent humidity, and 1.5 mil thickness.
Curing and recoat time is extended by multiple coats and by excessively thick coats. Temperature and humidity move it too, since the published figures assume 72 degrees F and 50 percent humidity. Cold or damp conditions will slow it down.
If you apply one, wait the full 24 hours first. Allow 24 hours before applying a second coat or before topcoating with a different coating. Remember that additional coats extend the total cure time.
For best results use the product when the can is between 50 and 90 degrees F (10 to 32 degrees C), and store cans between 40 and 100 degrees F. If the can has been in a cold shop or truck, bring it inside and let it reach room temperature before spraying.
