About this product
A thin epoxy for soaking into rotted or soft wood. Unlike most epoxies on this site it is slower to tack-free (36 to 48 hours) than to pot-life out (20 to 40 minutes), which is the point: it keeps soaking in.
Using this specific product
TotalBoat Penetrating Epoxy is listed here as the Rot repair sealer version for rot repair, wood consolidant, and epoxy sealer. For mixing and curing epoxy, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.
Before you start
- Confirm the package says Rot repair sealer; related versions can use different timing.
- For rot repair, wood consolidant, and epoxy sealer, pay particular attention to mix ratio, batch size, temperature and pour thickness.
- The source gives no conditions for this time. At 75°F (24°C).
How to check readiness
Check the coolest or thickest part for firmness before sanding, demolding or loading. The data sheet gives a pot life of 20 minutes at 85°F and 40 minutes at 40°F. The data sheet gives a tack-free time of 36 to 48 hours at 75°F. Reserve full cure for demanding use, chemicals, washing, immersion or load—not merely gentle handling.
Avoid this mistake
A larger batch can heat faster while a thin film may cure more slowly.
