Good to Know
- Durabak begins to cure with exposure to air, so minimize exposure to air while working with it.
- The consistency of the Durabak should be runny, as it’s self leveling. If it’s thicker, you can add up to 15% xylene to thin it. It should be mixable after adding the xylene and back to a runny form. If it’s pasty and thick, DO NOT APPLY, rather reach out to us for assistance.
- You will have a few hours of work time once the can is opened (3 to 5 hours normally).
- A second coat can be applied within 1-2 hours, once the first coat is touch dry.
- After second coat is applied allow 24 hours before walking on it. Complete cure is about 5 or 6 days, so no heavy use until then.
When applying Durabak it is important to ensure that each coat does not get too thick. If Durabak is applied in a coat that is too heavy it will trap the curing gasses and leave pinholes which will eventually lead to discoloration in the Durabak.
Be sure to apply moderately thin coats of the Durabak and as a guide you should be getting coverage similar to what is laid out above.
- Temp should ideally be 60 degrees or above for the application, and above 40% humidity.
- Xylene should be applied immediately to clean up any misapplied Durabak.
- If taping off, use 3M Blue tape and remove immediately after second coat is applied.
